FRONT BY MARK FOWLER

That Wacky, Water-Resistive

Barrier So much change and yet so much remains the same. For years, the codes referred to this mystical product as the “weather” resistive barrier but the new I-Codes deemed it more appropriate to call it the “water” resistive barrier. The good news is that the acronym is the same and it remains the WRB in plans and specifications. Recent innovations also include new trowel or spray applied WRBs that are gaining in popularity. This editorial is not to promote or condemn paper, felt, housewraps or f luid applied WRBs as the more appropriate product; these are decisions by the architect and /or installer as to which is preferred for their particular project. I do believe that no single product is the answer to every scenario. The issue I have been tackling is the terminology or use of the phrases “primary” or “secondary” WRB. I wa s sho cke d to h ave some technical experts within our own i ndu s t r y a r g ue w it h me ab out the term inolog y of the W R B . I further found out that everyone has a different interpretation of what the W RB is as it relates to t he ph rase “pr i m a r y” or “se condar y.” I posted this question on the Wall s an d C eilings Bulletin Board (w w w.i-boards.com / bnp/wc) to get a sense of what the guys in the trenches think. After enduring some attacks for wasting everyone’s time, I have come to some conclusions that I think are important to share. The first issue is the “what-awaste-of-time” scenario: Why is this important? Let’s just put the WRB up and just move on. Oh, if life were that simple.

NOT LIKE YESTERYEAR It was simple a few decades ago. But today, litigation is on the front burner and those that do not pay attention to it will get burned. I learned the hard way in construction litigation: right does not make right in litigation. Almost all cases have lots of grey areas; not everything is black and white and covered implicitly by the code or a standard. That is when the experts step in and begin to pontificate their opinion and expertise. You have your expert and the other side has theirs. In the case of these grey areas, the mediator, arbitrator, judge or jury will often rely on one important factor: Who is the most believable expert? The fact that you have put on the product for 25 years, and used the “that’s the way I have always done it” statement carries very little weight in litigation. What does carry weight is your in-depth knowledge of the issue, understanding the controversy that may surround that particular issue, and your ability to back-up your statements. Picture yourself in a jury box and imagine two experts giving testimony on a subject you know very little about. One expert says he knows the subject matter better than anyone else and states his case and although has very little to back up his bravado and claims, he is confident and unwilling to bend. The other expert gives a clear and easy to comprehend description,

understands and acknowledges the controversy that exists and brings in various sources of information to back up his statements. Who do you believe? I can assure you, the second expert tends to win more often than not. The WRB is one of the more controversial products in our industry. And that is the perfect sentence to explain if the WRB is the primary or secondary water barrier. We always have to start at the code as the beginning to prove or disprove a position. When it comes to the water resistive barrier, as per code, there is only one WRB. The WRB can be paper, felt, housewrap or a liquid applied but it is the one and only WRB as it is a product. However, when we sp e a k of managing moisture from a “system” perspective, there are various methods (i.e., barrier, concealed barrier and rainscreen). These are layers of defense to keep moisture out. In almost all exterior assemblies or systems, the WRB is the final barrier to keep liquid water out of the wall assembly. I have often referred to the building paper as the secondary WRB, which is technically incorrect. There is only one WRB but there are two lines of defense against moisture in most claddings over building paper, and as such, the WRB then becomes the secondary line of defense against liquid water. While this seems like splitting hairs or arguing over semantics, this is what construction defect litigation is built on. Experts who understand this and can persuade the party responsible for passing judgment will typically prevail. As a manufacturer, dealer, contractor or even an expert witness, you have to know where the other side is coming from and where they plan to go. I have seen cases lost over a simple misunderstanding of terminology and an innocent contractor get shafted, and that’s why it is important to know this stuff. W&C

NEW STEEL FRAMING ASSOCIATION FORMED A collective of cold-formed steel manufacturers, suppliers and contractors have formed the Steel Framing Industry Association. Open officially on January 10, the association will be headquartered in Northern Virginia. “The SFIA will unify our industry and help make all our businesses more successful through a number of initiatives,” said SFIA interim President Bill Courtney (ClarkWestern Building Systems). “The SFIA will advocate on behalf of companies in the Cold Formed Steel Framing Industry to expand the market through code compliance, promotion, education and innovation.” According to SFIA interim Vice President Kennon Whaley (Southeastern Stud & Components Inc.), “SFIA will be an inclusive, industry-wide association because membership is open to CFS product manufacturers, steel mills, coil coaters, steel coil suppliers, connector and accessory manufacturers, panel and truss manufacturers, equipment and tool manufacturers, supplier/distributor yards, design professionals and contractors.” According to Interim Secretary John Roberts (Dietrich Metal Framing), the association will implement an independent, third-party code compliance certification program for exterior and interior framing products early this year. The program is open to the more than 70 CFS product manufacturers and will ensure that products produced by manufacturing members meet all applicable building codes. Also, the association is planning to develop an independent third-party code compliance certification program for framing accessories. The SFIA will be guided by a Board of Directors that will meet a minimum of two times each year. The Board of Directors and Officers will be elected at the first membership meeting on April 5, 2011, in Las Vegas, during the AWCI Convention and INTEX Expo. The

board will consist of four officers, two small, two medium and two large CFS product manufacturers, one steel mill, one supplier/distributor and one contractor.

GA UPDATES ONLINE CEU PROGRAMS The Gypsum Association has recently updated its three on-line education courses: Understanding the GA-600 Fire Resistance Design Manual (FRDM06); Understanding the Finishing of Gypsum Panel Products Using GA-216 and GA-214, Recommended Levels of Gypsum Board Finish (LFGP07), and Application of Gypsum Panel Products (GA216E). Each of these courses has been approved by the American Institute of Architects as being eligible for AIA CEU credits upon completion with a score of 80 percent or better. Completion of FRDM06 earns a twohour Health Safety and Welfare credit, and both LFGP07 and GA216E earn a one-hour HSW credit. Each of these courses has been updated to reflect revisions of documents that they reference and changes in the model codes that have occurred since their initial posting. None of these changes substantially alters the content of the courses as initially posted. The association’s online courses are available to anyone by going to www.gypsum.org/OnlineCourse/ index.cfm. There, first-time visitors will be required to create an account using an email address for a User ID and an eight-digit number for a password. AIA members are advised to use their AIA membership numbers for their passwords, which facilitates automatic reporting of the successful completion of the courses with AIA. The programs are designed to pick up where they are left off, so that participants may take the courses at their own pace in several sessions. The software is also equipped to remind participants of their passwords using the email addresses they initially sign in with.

DOW ACHIEVES RECERTIFICATION FOR CRADLE TO CRADLE PROGRAM Building insulation products from Dow Building Solutions have achieved recertification by the Cradle to Cradle Certification program, a well-known, multi-attribute eco-label that assesses a product’s safety and environmental impact. Originally certified and announced at IBS last year after rigorous analysis, Styrofoam Brand Extruded Polystyrene Foam Insulation and Safetouch Fiberglass-Free Insulation both recertified at the Silver level, while Styrofoam SIS Brand Structural Insulated Sheathing, Thermax Exterior Insulation, and Styrofoam Brand Spray Polyurethane Foam Insulation all achieved BASIC recertification. Unlike single-attribute eco-labels, the Cradle to Cradle approach takes a more comprehensive assessment in evaluating the sustainability attri-

butes of a product, as well as the practices employed in manufacturing the product. Administered by McDonough Braungart Design Chemistry LLC, a global sustainability consulting and product certification firm, the Cradle to Cradle Certification process evaluates products in five categories: material health, material reutilization, renewable energy use, water stewardship, and social responsibility. Dow products that have achieved renewed Cradle to Cradle Certification are eligible for points that contribute toward various building certifications, such as the U.S. Green Building Council LEED Rating Systems and the National Association of Home Builders’ National Green Building Program.

Where’s the Drainage A

s it pertains to stucco installations, the I nternational Codes require “a water-resistive vapor permeable barrier with a performance at least equivalent to two layers of Grade D paper” on wood-based sheathings. To meet the requirement of installing two layers of water-resistive barriers, most contractors opt for installing a double laminate roll of Grade D building paper in lieu of successive applications of a single roll (see Figure 1, Double Laminate Roll Installation Method, on page 24). A new controversy brewing in residential stucco installation now questions that practice. It began with a voicemail from a bu i ld i n g of f i c i a l i n a we s t-

Should the most effective drainage plane behind l b ildi paper? ? stucco rest b between two layers off building A debate has risen. By Steve Pedracine ern suburb of Minneapolis, who in his message to the Minnesota Lath and Plaster Bureau, expressed some concern about the drainage pla ne beh i nd st ucco wall claddings. It seems a new “expert” on the Minnesota stucco scene contends that the effective drainage plane behind stucco rests between the two layers of building paper. A further contention is that the double-laminate single application method of installing the building paper is ineffective and actually may exacerbate moisture intrusion

issues. Accordingly, the two layers of building paper must be put on in successive applications before the lath and stucco. Frankly, I was glad it was a voicemail, because it dumbfounded me at first. It makes sense when you look at it graphically. “ Wow, he m ay b e r ig ht ,” I thought, as I crudely drew the application of how two separate successive layers of building paper would be installed and function. Have we been wrong all these years? But looks can be deceiving.

where plywood backs up the lath and plaster. Evidently the plywood sheathing pulls the water out of the plaster right through the paper backed lath. This osmosis effect tends to make plywood sheathing swell and at the same time deprives the plaster of water needed for adequate hydration. A simple solution to this problem appears to lie in the installation of an additional layer of weather resistant paper. The results are dramatic and well worth the added cost when lathing over plywood or any large wooden member.” Walter F. Pruter, Furring and Lathing Information Bureau

STUCCO + PLYWOOD = CRACKS

Plane? TWO LAYERS The building codes have held the requirement for two layers of building paper over wood-based sheathings since 1982. Coincidentally the code does not specify if the paper has to be put on in successive applications. Why is it that stucco requires two layers of water-resistive barrier (WRB) where most cladding installations typically require one? To answer this question the Lath and Plaster Bureau went back in time to April 1981 to a symposium on Portland Cement Plastering: “In many parts of the country, plywood sheathing is used to construct horizontal shear resisting elements on a building. It has been observed that the incidence of plaster cracking is usually more extensive and severe

The information extracted from Walt Pruter’s summary is eloquent in its simplicity. Stucco is not a difficult product to understand. It’s a wet, plastic mass that is applied to an armature (lath), which holds it in place as it cures by hydration. If you are going to install it over a material that wants to suck the moisture out of it, you can initially expect shrinkage cracks as a result. Of course, the latent effect of the moisture going into the plywood is that it in turn tends to swell. And as the plywood swells, this results in further cracking of the stucco. Unfortunately, the many detractors out there often attribute these cracks to deficiencies in the stucco or its application, rather than the fact that the restraint capacity of the stucco to resist the cracking has been exceeded. What transpired at that symposium in 1981 was not any great revelation. It was common sense. The authors of the two layer requirement did not complicate it by requiring that the drainage plane be between the layers of building paper. Let’s think about this for a minute: How is stucco any different than any other cladding? Where is the drainage plane behind wood siding? What about cement board or vinyl? That’s right, the drainage plane is between the cladding and water-resistive barrier that is put on over the sheathing. But stucco is different. So we need to change the rules for stucco? No we don’t. I hate to break it to the detractors out there but the drainage plane with stucco is no different than the aforementioned claddings. It is between the cladding (stucco) and the building

The back of a piece of stucco removed from a house. Picture proof that building paper does not stick to stucco.

paper (WRB). Putting the drainage plane between the layers of building paper, defeats the strategy of keeping moisture from the sheathing.

PROVEN DRAINAGE PLANE I am sure that there remain skeptics out there that would say that stucco is a barrier cladding because the stucco they suggest becomes bonded to the building paper during initial application. Some might even say that the lath actually affords some drainage capacity between the stucco and the building paper. The fact is that the drainage characteristics of stucco over building paper have been proven by some noteworthy testing: • In 1996 the Northwest Wall and Ceiling Bureau sponsored research conducted by Federal Testing Laboratories, to test stucco’s water resistance and drainage capacity. When water was sprayed into a designed opening at the top of various stucco panels, it was found to have drained down the full 9-foot height of the panels and weep out the bottom. Interestingly, what was discovered was that as the wet stucco cures and moisture is drawn from the building paper back into the stucco; the initial bond between the stucco and the building paper releases and shallow channels develop in the building paper that allow for the passage of moisture. • This was affirmed in a study sponsored by the City of Seattle in 20 02 . Computer modeling

Where’s the Drainage Plane? conducted by Oakridge National Laboratory observed that: “Proper installation of weather-resistive barriers and integration with flashing is one of the most important factors in the successful performance of exterior walls. Two layers of WRB (one layer installed over the other) behind the exterior cladding was shown to provide better drainage control over one layer).” As an aside, the Minnesota Lath and Plaster Bureau did its own in-house

testing some years back. Initially we were a little alarmed because drainage was not apparent until the stucco reached an optimum cure at 30 days. At that time, the drainage became readily apparent. The key it seems is the proper control of the components of cement, lime, water and properly graded aggregate.

STUPID IS AS STUPID DOES In a former occupation, I had the opportunity to investigate moisture intrusion issues for a well-known

FIGURE 1

FIGURE 2

EIFS company. One thing that stood out in my mind was that in the tearoffs and re-cladding of many of these homes they often used cedar shakes as the replacement cladding. One day as I stood watching two laborers install housewrap on a home, I noticed something very peculiar going on. They were installing the housewrap from the top of the house working down. Now back in those days, they weren’t perhaps as knowledgeable in the physics of gravity, but this method resulted in the housewrap being installed with reverse laps to a shingle board fashion. The obvious implication being that moisture would run into the wall plane instead of away from it in a rain event. Perplexed by this, I pointed this anomaly out to the local building official, who promptly suggested that I mind my own business. Why do I bring this up? Let’s look once again at the detail (see Figure 2). At first blush, it appears that maybe it would be beneficial to have the drainage plane between the layers of building paper. But compare that detail with Figure 3. What happens when you put the two layers up in two separate applications? The second layer creates reverse laps from the first layer. Taking that into account, the graphic takes on a whole new perspective. We at the Minnesota Lath and Plaster Bureau certainly don’t claim to be “experts” but we are knowledgeable and what seems apparent is that installing building paper in a double laminate roll is doing exactly what Walt Pruter explained so many years ago. In stucco applications, it provides the optimum protection from moisture issues and crack control. But those reverse laps illustrated in all the other scenarios it seems would amplify any moisture problem rather than mitigate it.

HOUSEWRAPS

Application of two layers of building paper installed in separate successive operations. The contention is that this method of operation is better than installing the building paper in a single application of a double laminate roll (Figure 1). This is because the drainage plane can be moved to the area between the layers of building paper, rather than between the building paper and stucco. This is ineffectual in both respects because if the drainage plane is moved between the layers of building paper, it gets redirected out between the stucco and building paper, anyway. Read the full article for a better understanding.

Water-resistive barrier housewraps present special challenges when used in a double layer application. Most of these materials are comprised of polypropylene, polyolefin or polyethylene synthetics. What has been demonstrated in their use is that they bond tenaciously with stucco. So what happens to the drainage

plane in a two layer application of one of these polymeric housewraps? It would seem that this would suggest that the drainage plane would be between the layers of housewrap. However if this was not planned and executed with the flashing tied to the drainage plane, disaster might follow. In typical stucco installation practice, however, it would seem rare to have two layers of these products applied in separate applications. Economics usually prevents it from happening. The fact of reality is that a layer of housewrap is often paired with a single or sometimes even a double layer of building paper applied over the top of it (see Figure 4). In that scenario, the flashing attachments to either the housewrap or the building paper would not it seem, significantly compromise the drainage capacity of the stucco installation. What if we reverse the process and put the housewrap on top of the building paper? (See Figure 5.) Assuming that the stucco will bond to the housewrap, the effective drainage plane would now be the area between the housewrap and the building paper. Besides the fact that there is no drainage capacity between the housewrap and the stucco, we can also identify a potential issue where a reverse lap from the housewrap application may be the source of pent-up moisture. However, given the fact that these reverse laps are minimized by the wider width of most housewraps, these potential trouble spots would be few. What seems to be obvious in this scenario is that the value of the housewrap bonded to the stucco is negated, and for all practical purposes we are essentially back to one layer of WRB. As to whether this can perform as well as two layers of building paper, we will let you be the judge. The Minnesota Lath and Plaster Bureau, however would suggest that those words put forth by Walt Pruter nearly 30 years ago should not go unheeded. W&C

A Clean Washer W

eathering the storm was all any of us could think about du ring the 1996 E I FS moistu re intrusion crisis. It all started in a lovely upscale neighborhood in Wilmington, N.C . A lmost overnight, class-action lawsuits against the EIFS manufacturers, distributors and those hard-working applic ator s were m a k i ng he ad l i ne s across the country. Needless to say, my livelihood and that of many of my customers and fellow employees were suddenly in jeopardy. These were the darkest days of my life as I spent the next several years doing my part for a local trade association by speaking with state legislators and working with several national associations trying to revive the industry. The culprit was mainly due to shoddy construction practices: roofers leaving out critical roof to wall flashings and window installers leaving out

Quality, manufacturer-approved EIFS washers and fasteners should be the only option contractors choose. By Craig Barnaby

pan flashings were found to be some of the early instigators. Afterwards, a comment was made by a close friend, the president of CLAPCA, that our industry could not stand one more massive blow. From there forward, it was up to those of us who made our living off of the EIFS, stucco and plastering trades to get it right.

WASHERS, NAILS AND SCREWS EIFS, stucco and plaster fasteners are a critical component for mechanically attaching EPS boards to the substrate. We see almost every day how companies are opting to use cheap substitutes like galvanized roofing nails, 8d nails, or substandard washers. We suspect it’s

because they are cheap and can be hidden from view when coated. We turn away orders for these and other items like the small, thin (weak) green plastic tabs. Zinc, phosphate and oil screws that are used almost exclusively for interior dr y wall applications are being used to secure EPS to the exterior substrate. I would offer this scenario. If someone were willing to cut corners by using non-qualified screws and washers, wouldn’t they also scrimp on the amount of adhesives, mixing method or the application process they use to apply it? If this seems as likely to you as it does to me then why not strengthen this method by mandating, “To be used with only manufacturer approved fasteners.”

Your EIFS manufacturer should approve the specific fastener, screw and attachment pattern that you are going to use with the system. If in doubt, contact an EIFS supplier and request a letter showing which suppliers are approved sources for mechanical washers and fasteners, or contact the manufacturer of the fastener—they will be able to provide you with a letter from the EIFS manufacturer showing that its fastener has been approved. Statements such as, “I am installing a non-warranted system so I don’t need anything expensive” are not new to any of us. But does anyone really believe that an EIFS manufacturer provides a non-warranted system? In the 23 years I have been in this business, I have never seen a shred of evidence that an EIFS manufacturer has a non-warranted system. I would dare say this goes for reinforcing mesh also. Independently tested fasteners are made up of a coated screw, appropriate for the substrate and framing, and a quality 2-inch diameter fingerclosure washer. This is the minimum requirement. Simply saving money on an inferior screw will not cut it. An inferior screw will fail and set up the conditions for an EIF system failure. Use a screw that meets or exceeds ASTM-B117. Thin plastic washers that have not been independently tested for wind-load pull off are simply not worth the risk. W h i l e of t e n ove r looked, the screw hole flaps serve a critical function by sealing off the screw

and preventing thermal shorts that could occur on the finished wall. Today’s engineered manufacturer approved fasteners have keyholes that form a strong mechanical bond with the basecoat. Recent development improvements to the cone design allow use on EPS thicknesses down to 1 inch; this came about by a total depth of 7/16 inch of the washer while still maintaining the maximum wind-load requirement. Depth control is an essential step in the installation process. Think of it in the same way you would when properly installing drywall screws. Install a fastener too deep into the foam and you will have a build-up of basecoat that will cause a crack and a visual “cat’s face” on the finished product. Also, if the fastener is driven too deep, the wind-load that


you want to achieve will be negatively impacted. It is recom mended you use a “depth s top” o n you r

A Clean Washer drill gun to control pull-through of the manufacturer-approved fastener. Proper fastening pat terns are a cr it ic a l pro c e ss i n at t ach i ng the foam board to the substrate. Always consult the specifications of your EIFS manufacturer to ensure proper spacing for maximum windload resistance.

GET ATTACHED Manufacturer-approved fasteners have been used for years in lieu of adhesives. A function of the approved fas-

tener allows the application of EIFS over substrates that cannot be adhesively attached; additional applications can proceed in adverse weather conditions. Architects will have peace of mind that the system they have specified is firmly attached to the substrate. Fastener attachment can also be used with great success when mixed with adhesives. Many things can adversely affect an application using only adhesive; weather outside of the manufacturers’ specifications (too cool or wet), rasping the foam before

the adhesive is cured, or improperly mixing the adhesive. These are issues that will cause a system failure. All of these can be overcome by introducing manufacturer-approved fasteners into the mix. A side benefit to the adhesive and fastener use is rasping of the EPS, which can commence immediately due to the fastener holding the EPS firmly to the wall while the adhesive cures. In my opinion, it should be used in every EIFS application.

Want proof that a combination of adhesive and basecoat work well together? Myrtle Beach, S.C., had a tornado form from two water spouts that landed just south of the famous Pavilion on Ocean Boulevard. These two powerful water spouts churned their way between four high-rise hotels, causing $8 million in damages to the hotels and surrounding area. According to the EIFS installer, Danny Bonnell, founder of Commercial Systems Inc., the company had just completed the EIFS on two of the hotels using a combination of adhesive and manufacturer-approved fasteners. The damage inflicted was superficial and repairs were limited to areas where flying debris scuffed the surface. Bonnell stands by his record of no failures in a high-risk hurricane prone part of the world. Also, he sleeps very well at night knowing he has done the best he can do for his customers’ projects. Bonnell went on to say the other two hotels, in which his company did not do the EIFS installation, did not fare so well. The first one was applied using only adhesive. This project had massive failures in the form of huge areas that were ripped off the substrate. The other was a traditional, hard-coat stucco building in which the lath had been attached using only stub nails. Large sections of the stucco ended up on the ground.

By Del Williams VOCs, after all, serve a vital function—essentially keeping the components from reacting and hardening prior to use. The answer, it turns out, is to remove the very reason VOCs exist in paint in the first place. The new ceramic coating does not come pre-mixed. Instead, the coating consists of two, non-hazardous ingredients that do not interact until applied by a plural component spray g u n l i ke t hose commonly used to apply polyurethane foam or polyurea coatings. Since the components are not mixed and do not meet prior to application, the need for VOC-generating ingredients is completely eliminated.

The final ceramic coating, which is more comparable to a thin layer of cement approximately 6 mils (2mm) thick than traditional paint, delivers a tough-as-nails corrosion-resistant coating that can stand up to just about any application in the industrial, commercial or residential sector.

CONTRACTOR APPEAL When Andy Robbins, CEO of A & K Painting, a Charlotte, N.C.,-based industrial and commercial paint contractor that does work in five states, first heard about the new ceramic coating the concept intrigued him. “The environmental guidelines of the last decade are rapidly becoming standards,” says Robbins. “Since environmental codes are tightening for new builds, remodels, and existing facilities, reducing or eliminating

VOCs in paint has been a growing concern for us and our customers.” Captivated by the possibilities the protective ceramic coating presented, Robbins stayed in touch with the developer, EonCoat LLC, ultimately visiting the plant, participating in testing, and providing R&D feedback from the professional paint contractors’ perspective. “For industrial and commercial customers looking to limit VOCs and HAPs to meet stricter regulation, EonCoat is a proactive way to do so,” says Robbins. “Before the two components are combined in the spray gun, they’re kept separate and, if spilled, are easily cleaned up as mild, non-hazardous substances. After they’re combined, they’re completely consumed and dry within seconds of application. There are no fumes. Contractors could literally spray within 10 feet of someone working in an occupied space with no concern for odor or getting residue on carpet, computers, or office furniture.”

LABOR SAVINGS One coat application and minimal prep for the protective ceramic coating can save paint contractors up to 40 percent, since labor is cut in half and labor is typically about 70 percent of the cost of painting. Unlike paint, which usually requires a primer coat and two topcoats with at least eight hours drying time between each, the ceramic coating’s natural corrosion protection eliminates the need for a primer and a second topcoat. Because it dries within seconds of exiting the spray nozzle, high build coatings in one coat are possible. This accelerates facility maintenance return to service. “Since the protective ceramic coating is dry to the touch in seconds, there’s no wait to recoat,” says Robbins. “Contractors can high build exterior or interior surfaces immediately, which can expedite tight customer schedules. That means many coating jobs in occupied areas could get done in a single day or weekend, instead of taking several weekends waiting for multiple coats of primer or paint to dry.” T h e c e r a m i c c o at i n g b o n d s through a chemical reaction with the substrate, and slight surface oxida-

tion actually improves the reaction. This makes it virtually impossible for corrosion promoters like oxygen and humidity to get behind the coating the way they can with ordinary paints. The corrosion barrier is covered by a true ceramic shell, which resists fire, water, abrasion, chemicals, corrosion, and temperatures up to 1,000 degrees Fahrenheit.

FIRE RESISTANCE The coating has a flame spread rating of zero, which means that flame can be directly exposed to its coated surface and it will not catch fire unless enough heat is generated to make the substrate behind the coating self-ignite. “The anti-fire, anti-water, antiabrasion, and anti-corrosion benefits of the new protective ceramic coating make it a promising product to use for a host of applications from extending the service life of tanks, machinery, steam pipes, and cement floors to serving as slimmer, less costly alternative to existing bulky firewalls,” says Robbins. Another plus for contractors is how the protective ceramic coat-

ing can be applied on hot or cold surfaces from 35 degrees to 200 degrees Fahrenheit, which, unlike paint, makes it suitable for all weather application. “If we’re not painting or coating a substrate, we’re not making money,” says Robbins. “Hot or cold weather can halt a paint job; that’s not the case with the protective ceramic coating. It works well in high or low temperature, which means contractors keep working. “I’d have trouble believing its properties if I hadn’t seen them myself in hands-on application and testing,” he continues. “It opens possibilities for contractors from new builds, to retrofits, to maintenance in industrial, commercial, and even residential settings. My only concern is that our application of the protective ceramic coating does justice to the product itself. That’s why my company’s staff will get EonCoat-certified as soon as we’re able to.” W&C Del Williams is a technical writer based in Torrance, Calif.

A Pioneerin F

ounded in 1866 1866, Minnesota’s Carleton College was the dream of pioneers who believed that knowledge was the real frontier. And this pioneering spirit endures. For example, the small, private liberal arts school was the first college in the world to have an industrial-size wind turbine to generate energy. It is one of only 15 to receive an “A” from The College Sustainability Report Card (www. greenreportcard.org), an interactive website that provides in-depth sustainability profiles for hundreds of colleges in all 50 states and Canada.

Carleton College’s extreme dedication to sustainable building resulted in green residence halls built with energy-saving ICFs. By Troy Gibson, LEED Green Associate Now, Carleton College has pushed the boundaries even further with two new sustainably designed, energyefficient residence halls designed to achieve LEED Gold certification. Designed by LHB Inc. architects, the new Cassat Hall and Memorial Hall buildings feature 91,536 total square feet, including 56 doubleoccupancy rooms, 26 single-occu-

pancy rooms, 21 suites and nine full kitchens. The buildings’ footprints were offset by a donated piece of land north of the campus. T he C a rle ton C ol lege de sig n team identified more than 36 distinct aspects to the residence halls that are deemed sustainable features, including low-flush toilets expected to save 30 percent on

There are also meters for water use and steam generation. Photovoltaic panels help supply electrical needs, estimated at more than 10,000 kW annually. During construction, 90 percent of all waste was diverted from landfills and incinerators and redirected back to the manufacturing process. (A full list of building materials is available online at www.EDCmag.com.)

COMBINING AESTHETICS WITH ENERGY EFFICIENCY Insulated concrete forms, or ICFs, were chosen to assist in achieving optimal energy efficiency. The team focused extensively on the building envelopes of the new dormitories. “ICFs were selected for their sustainable advantages, including durability, high thermal mass, and low air infiltration,” says LHB Architect’s Maureen Ness, AIA, LEED AP, CDT. Due to the energy performance characteristics of ICF technology and the special occupancy nature of the

buildings (residence halls are occupied from late August through April), low-energy-use electric fans replaced the requirement for air-conditioning. Heating needs are met by in-floor radiant heating systems, which utilize steam supplied from a regional steam-generation plant, and supplemented, as needed, with individual room side-panel electric heat. Noise attenuation, local materials, building comfort and safety, and indoor air quality requirements were also met by the performance characteristics of ICFs, which also accommodated the gable rooftops. “Reward Wall Systems’ ICF product met all of our sustainable design criteria as well as providing the versatility required for the unique building footprints,” Ness says. The project features ICF loadbearing walls in conjunction with hollow-core precast floor slabs. Aesthetic requirements were fulfilled with the ICFs, which provide the versatility to use any exterior finish application. Permanent attachment of the brick veneer to the concrete wall was required by the structural design. Reward Wall’s stainless steel tieKey was used to aid in the labor efficiency required to maintain and exceed construction schedules. Reward Wall Systems and distributor Cemstone worked extensively with the architect during the design phase to assist in the development of accurate cost budgeting. According to the team, the school saved 20 percent per square foot by using ICFs versus standard

poured walls. According to recent d at a prov ided to Rewa rd Wa l l Systems, the college spent a total of $54,000 additional dollars to upgrade a building with ICFs, PV systems and other green enhancements; the college is expected to save more than $29,000 in total

energ y use per yea r (exclud i ng the cost savings from not using air conditioning), meaning a total payback of only 18 months.

pleted on schedule and on time for the students to move in at the start of the school year. Every lobby or common area in the school has an interactive touch-screen monitor showcasing features of the building. Currently, the college is running energy contests for the students to see who uses the least amount of energy per floor and per room. The college is also holding seminars to educate the community and its students on the green features of the school and how those green features make an impact for the community. Carleton College is very serious about its obligations to be a good steward—to protect the environment and be respectful of the planet. This ICF project now has become a benchmark for schools to monitor and an example of how to get students to play an active roll in curbing energy use. W&C

FINISH LINE BY ROBERT THOMAS

Beefing Up EIFS I often get calls from people wanting to “beef up” the performance of their EIFS walls. There are some things you can do to improve performance and this month’s column has a potpourri of strategies for common problems. IMPACT RESISTANCE Since in most wall areas the EIFS is never in contact with hard objects that can cause dents and holes, the use of standard grades of EIFS with light reinforcing mesh works just fine. During the phase of designing the façade, areas that need extra reinforcement can be identified and those areas can be beefed up using heavy reinforcing mesh. Wall areas that fall into this category include the bottom of the wall near grade and sidewalks, and around windows where window washers and maintenance staff may be working. Sometimes, this extra level of reinforcement is simply not enough or is never installed. Is it possible to retrofit an existing EIFS to improve its resistance to impact damage? Yes. There are several ways. One way is to add extra layers of mesh on top of the existing EIFS lamina. This is done by first filling in the existing EIFS finish with adhesive, and then adding additional layers of basecoat adhesive,

mesh and finish. The existing finish needs to be clean and the texture of the finish is filled with basecoat adhesive to make it smooth. Usually, a noncementitious adhesive is used. The additional layer can be installed only where needed but has to be done carefully, lest the increased thickness in the new areas become visible. A non-EIFS solution is to keep hard objects from coming into contact with the EIFS in the first place. This is usually done by placing barriers next to the EIFS. Pipes filled with concrete, and embedded in driveways, are used near truck doors. Heavy metal angles that protrude from the lower horizontal edge of a wall near a sidewalk can keep people and shopping carts away from the wall. Shrubbery can be used on grade to keep lawnmowers and snow plows away.

CHANGING THE TEXTURE The texture of an EIFS finish can be changed. The trick is to fill in the

existing texture to make it smooth, and then apply the new finish; it’s hard to get a consistent texture when applying one-textured coating over another. Usually, a noncementitious basecoat adhesive is used to fill in the texture.

INSULATION LEVEL Although EIFS is highly energy efficient, sometimes even more insulation is desired. If the supporting wall is hollow (i.e., stud framing), additional insulation can be added from indoors. Likewise, insulation can be added on top of the interior finish but this requires dealing with electrical fixtures, ducts and doors, and also takes up floor space. Adding more EIFS on the outside is possible and it doesn’t interfere with the ongoing use of the building. New EIFS insulation, basecoat and finish can be glued onto the face of the EIFS. Attention needs to be paid to the edge of the EIFS, where there are openings and where there are objects projecting through the EIFS.

ROOF INSULATION Although EIFS is an energy efficient wall cladding, if the objective is to save more energy, the roof should be considered too—not just the walls. This is especially true on large, single-story windowless buildings such as warehouses, where the majority of the heat loss or gain is actually through the roof, not the walls.

Here’s a before and after example of an old building that was redone with an EIFS finish that looks like brick. What a difference. Photo courtesy of Dryvit Systems.

the

FINISH LINE AIR LEAKS EIFS is seamless and air does not seep through the coating. However, air can get around the edge of the EIFS if the perimeter is not sealed. Caulking does not last forever and maintaining the seal is simply a matter of checking the condition of the sealant—especially at windows and doors—and replacing areas that are worn out. Removing old sealant, without damaging the EIFS, needs to be done carefully so it does not damage

the EIFS basecoat. The new sealant should be attached to the basecoat, not the finish. Solvents should not be used to remove old sealant, as some solvents can leech through the EIFS coating and dissolve the foam. It may also be possible to apply new sealant over old. This can make for big, ugly joints but can save a lot of time and money. The old sealant should have a bond breaker material applied to it, so the new sealant does not stick to it. The use of preformed sealant strips, such as Dow Corn-

ing’s 1-2-3, are cost effective. They change the appearance of the joint from looking like an architectural joint to one similar to a batten.

ADDING EIFS WITH DRAINAGE When the big news took place in the 1990s over water leakage that was supposedly caused by EIFS, the design of EIFS as a cladding system took a step forward. The building codes mandated adding drainage to EIFS, and EIFS producers responded by coming up with a number of ways of incorporating drainage. Basically, what the drainage system involved was putting a water resistive barrier over the wall sheathing, and then creating a cavity between the inside of the EIFS insulation and the WRB. This drainage capability was intended for use in new construction, not as an add-on. Nevertheless, people asked if drainage could be retrofitted onto an existing EIFS. The basic answer is no but it has been done— with difficulty. The problem is that EIFS cannot be disassembled and reused and the drainage system is buried in the EIFS. One way is to strip off the entire EIFS to the substrate, and install a whole new EIFS with drainage system. Needless to say, this is expensive and time consuming. An extenuating circumstance is the fact that the sheathing substrate usually gets ruined in the process of taking off the EIFS. Thus, it often needs to be replaced. It is possible to put a new EIFS over an existing EIFS and incorporate the drainage capability in the new EIFS. The existing EIFS lamina can act as the WRB and the new EIFS uses grooved foam or a drainage matt to provide the drainage. A problem with this approach is it does not necessarily address the true source of most leak problems. The real culprit has been shown time and again to be the edge of the EIFS, particularly where there are flashings or caulking, or the lack thereof. Hence, the value of retrofitting drainage to an EIFS is sort of a waste of time compared to the benefits of carefully doing the details at the edge of the EIFS.

SLOPES AND FLASHINGS Speaking of flashing, it was common for many years to not use

36


f lashings at key places in EIFS, instead relying on caulking. Areas of particular concern include window heads and sills, parapets and penetrations, such as HVAC sleeves. Adding flashings that actually work to an existing EIFS is often difficult, as the flashing is normally attached

with commercial-grade ex terior acrylic latex paint. It helps if you know whose EIFS product it is, as some finishes contain chemicals that increase water repellency, and thus paint has a hard time getting a good bond. EIFS manufacturers make maintenance and repair “paint” ver-

As with any building envelope system, it’s a good idea to survey the façade once a year ... to the substrate, and the presence of the EI FS makes it necessary to remove a band of EIFS, install the flashing and then rebuild the EIFS. This is expensive and often leaves visible repair patches. The same is true with windows, where there’s often not enough space to slip a flashing under a windowsill far enough to gather the water and actually do some good. As for shallow sloped areas, especially at sills, the only real way to increase the slope is to cut away the EIFS to increase the slope, and rebuild the EIFS.

ADDING CAULKING/EXPANSION JOINTS S omet i mes , a n ex pa nsion t y pe caulking joint is not installed originally at a location where one should have been placed. Then a crack sometimes occurs. Simply patching over the crack with more basecoat and finish does not work—it’ll crack again. A real working caulking joint is needed. To install such a joint, the EIFS needs to be cut back several inches on either side of the crack. Then new foam insulation is installed, complete with a backwrapped edge. The existing finish is ground away and the new basecoat is overlapped onto the ground area. Lastly, the finish is applied and then the sealant. Carefully executed, the repair is hard to see, and eventually blends-in as the finish coat weathers with age.

sions of their EIFS finishes, which would be compatible. The EIFS finish needs to be thoroughly cleaned first. The paint can be applied by spray, roller or brush. The paint tends to fill in the texture, giving a smoother appearance.

Jobsite Waste

AN ANNUAL REVIEW As with any building envelope system, it’s a good idea to survey the façade once a year to see if anything odd has occurred since the last rev iew. C racks , dent s a nd worked-out caulking are common. On mid-rise buildings, a mobile work platform allows you to get close to the wall at the upper stories. On tall buildings, a swing stage works well. I n any event, you do need to get right next to the wall and be able to touch the EI FS , joints, f lashings and windows. I have several long-term clients who own a lot of large buildings who do this on a regular basis. Although it seemed to them to be a waste of money initially, it has saved them money in the long haul, as they were able to detect upcoming problems before they got out of hand. This especially includes leaky windows and balcony walls made of EIFS. W&C

GYPSUM BY MICHAEL GARDNER

Heating and Ventilating a Room to Dry

Joint Compound I don’t know why, but the columns we contribute on drywall finishing generate more response and discussion than any other topic—and not all of the response is friendly. We can’t avoid discussing drywall finishing for the subject generates a reasonable quantity of the technical inquires that come into the Gypsum Association. So at the risk of personal insult and injury, let’s jump into one facet of drywall finishing that generates a lot of cold weather discussion: artificially heating and ventilating a room to dry joint compound. The ideal environmental conditions for drying joint compound are a temperature range of 65 degrees to 80 degrees Fahrenheit and a relative humidity between 20 to 40 percent. The working space should be conditioned for a few days prior to the application of the joint compound, ideally with a warm, gentle breeze flowing through the area to remove excess humidity. At 70 degrees Fahrenheit and an RH of 30, joint compound under tape in a ventilated room will dry in approximately 12 hours. In that environment, you can walk away from a job at 3 p.m., and by 7 a.m. the following morning, the joint compound will be dry.

ENVIRONMENTAL CONDITIONS However, warm, dry, and breezy environmental conditions are not the norm for extended periods in much of North America – much less a construction site. A typical October day in Seattle, for example, has an average temperature of 46 degrees Fahrenheit and an afternoon RH of 70 to 80 percent. In such conditions, a coat of joint compound will take at least two days to completely dry. Make the work space colder or more humid, and the compound installed on Monday morning may still be wet on Friday afternoon. Moreover, cold and damp weather also can cause the edges of gypsum

38


board to soften if wet joint compound is permitted to sit on the face of the board for an extended period of time. Therefore, artificial heat and extra ventilation are often needed to create an environment conducive to the drying of joint compound. But in adding heat to an environment, one must be judicious and cautious. Excess heat can negatively affect the ability of the joint tape to bond to the face of the gypsum board. It also can cause joint compound to dry so fast that it shrinks excessively – remember, it shrinks some under optimum conditions—and it can cause cracks to form at the edge of the tape. Superheating a surface finished with compound, or applying wet compound to a joint not yet dry, may not cause an immediately discernable problem; however, it will increase the possibility that joint problems will emerge in the future. For example, joints that are painted when wet may continue to shrink or darken as they dry. Joint compound may turn yellow when exposed to fumes from partially combusted gases present due to temporary heating. And it is not only the joint compound that can suffer. Excess heat forced directly toward the face of gypsum board can, if the heat is quite extreme, actually cause the core of the board to begin to deteriorate as the chemically combined moisture in the gypsum crystals begins to dissipate. So what to do in January in Syracuse when there is drywall to be finished? How do you artificially heat or ventilate the environment to get the compound to dry so that the job

can be complete before August? First, don’t heat the space to a temperature above 95 degrees Fahrenheit and don’t allow heaters to blow directly onto surfaces that are drying. While you want the room warm, dry, and ventilated there are limits; you want to improve the environment, but you don’t want to take it to an extreme level. Creating a scalding hot, damp, or windy environment may put you in a worse position than the environment you originally encountered. Also, don’t create an extreme draft or permit artificial or natural wind to blow forcefully onto the finished surfaces and don’t permit cold air to blow directly onto the joints. You want a constant, gentle circulation of reasonably warm air to permit the joint compound to dry gradually. A forceful, cold wind blowing on a surface may, if the temperature is low enough, cause the joint compound, because it is water-based, to freeze before it has an opportunity to dry. You’re asking for trouble if you apply a coat of paint to or additional joint compound to a partially frozen joint.

SURFACE PREP Make sure the surfaces to be finished are warm before the compound is applied. The best rule is to condition the space to at least 50 degrees Fahrenheit for not less than 48 hours prior to the application of the joint compound. And make sure that the compound itself is warm and workable—leave the joint treatment materials in the room as the environment stabilizes so that they are the same temperature as the working surface. If it is frozen, don’t thaw it by adding warm water. And exercise caution when introducing heat using temporary heaters, whether fueled or electric, to prevent creating a fire or a personal injury hazard. It’s worth noting that some temporary heaters, specifically those that use gas or kerosene fuel, can introduce large amounts of water vapor into the atmosphere during the combustion process. When using fueled heaters, make sure that you create enough air movement to ade-

quately ventilate the work area so that the excess moisture created by the combustion of the fuel can dissipate. Many extreme weather finishing issues are best addressed by the use of setting-type compounds. Because setting compounds form a set based on their chemical formula and not by exposure to air, they can become firm and hard under less than optimal environmental conditions. However, note that setting compounds have some characteristics that are different than joint compounds – traditional setting compounds dry

Many extreme weather finishing issues are best addressed by the use of setting-type compounds. rock-hard and can be difficult to sand, for example—and that they should be evaluated based on the finishing requirements present on the specific project. You may not be alone in trying to modify the environmental conditions on a jobsite. Don’t get fooled by another trade that is introducing excess heat into your finishing area in an attempt to get another material to dry. Many building materials must be heated to facilitate setting or hardening. Heat is heat and it doesn’t matter where it comes from. Whether it is provided by you or another trade, if it can harm your material, it will. So be cognizant of the actions that other trades are using in an attempt to create an environment conducive to drying materials when damp or cold conditions exist.

BUSINESS BY JIM OLSZTYNSKI

Skilled

Labor Still In Short Supply

Some things are so counterintuitive it’s a struggle to explain them. For instance, we’re now three years into the Great Recession, in which an estimated 8 million people have lost their jobs and countless millions more are working par t-time or underemployed. Yet at the same time, reports keep popping up of labor shortages in construction and manufacturing. About a year ago Industrial Info Resources cited 688 renewable energy projects scheduled to begin construction in 2010 year across North America. Some of those projects were delayed or cancelled for vari-

40


ous reasons—financing chief among them—but others were held up due to a shortage of skilled craft labor in some areas. The media has been filled with reports recently about a coming revival of nuclear power projects in the U.S. Some 17 companies and consortia are considering building more than 30 nuclear plants, and the U.S. Nuclear Regulatory Commission is

actively reviewing 13 license applications for 22 nukes. If those projects ever get off the drawing board, it’s doubtful there will be enough skilled labor to pull them off in reasonable time. Fluor is one of the contractors expected to build some of those new nukes. IIR cited a Fluor procurement manager saying, “There’s not enough skilled labor in the market to build more than a few reactors at the same time. When we have four active [nuclear] projects under way at the same time, things will be interesting. I expect that labor costs will go up, perhaps sharply, around 2014.” The temporary staffing agency Manpower Inc. for the last five years has conducted an annual survey of tens of thousands of employers in 33 nations to determine the extent to which talent shortages are impacting today’s labor markets. Their latest effort in early 2010 found 31 percent of employers worldwide reporting difficulty filling key positions within their organization. The Skilled Trades category has topped the list each year of the survey. Also, the National Association of Manufacturers has been beating the drum for years about a shortage of skilled factory workers. Among NAM’s membership, their average age is around 50 and 90 percent of NAM members say they can’t find enough skilled production workers. This comes as a stunning revelation to people who read almost every day about factories laying off hundreds or thousands of people. How can manufacturers be shedding jobs all over the map, yet suffer a labor shortage? Upon further reflection, the discrepancy is not so mysterious. This is skilled labor we’re talking about. Many of the jobs that still exist in manufacturing are far removed from the assembly line tasks of the past that could be learned in a day. Many of today’s production workers have to know how to operate sophisticated computerized machinery, and it takes highly trained technicians to maintain and troubleshoot that equipment.

Likewise, it takes years to fully train skilled construction craf t workers. The best craft training traditionally has come out of the construction unions, but the unions are starkly diminished in numbers from what they used to be, and they are careful to calibrate their apprentices with the amount of work available. It wouldn’t make sense for them to train more journeymen than their contractors can employ, so in a dismal economy l i ke t h i s apprent ic e sh ip ra n k s diminish. Nonunion and company apprenticeship programs have even less incentive to expand enrollment in a down economy. Some short shrift the process and end up producing task workers rather than full-fledged journeymen. Anecdotally, I keep hearing of construction apprenticeship programs attracting older and college educated people. This is because we’re in an era when many white collar workers have been laid off from well paying jobs and the trades give them the best chance of recapturing their former earning power. But again, while this may boost the caliber of apprentices, until the economy improves the number people being trained is likely to be far less than the industry needs to sustain another boom. W hen t he m a rke t f i na l ly do e s recover, the construction skilled labor shortage is likely to get worse before it gets better. The Fabricators and Manufacturers Association, along with its colorfully named Nuts, Bolts & Thingamajigs Foundation, places some of the blame for skilled labor shortages on a society detached from its blue collar roots. A recent poll sponsored by NBTF showed a majority of teens—52 percent— have little or no interest in a manufacturing career and another 21 p erc ent a re a mbiva lent . W hen asked why, a whopping 61 percent said they seek a professional career, far surpassing other issues such as pay (17 percent), career

growth (15 percent) and physical work (14 percent). A major reason that kids don’t pursue careers in the skilled trades is the simple fact they are not introduced to them anymore. In the past, high school students could take a shop class and get a feel for working with tools, but today most don’t have that chance. Also, the old stereotypes of backbreaking labor and grimy working conditions in factories persist, even though most factories today are far cleaner, safer and more automated than in the bad old days. The same NBT F poll revealed that America has become a nation of “non-tinkerers,” with 60 percent of adults avoiding major household repairs. And, 57 percent state they have average or below average skills at fixing things around the house. This means young people essentially have no role models when it comes to repairing things themselves or taking pride in building something useful. Also, computer games have replaced tinker toys and erector sets as their favorite things to find under the Christmas tree. All of these factors make it a daunting task for manufacturing and trade recruiters to replenish ranks and staff up for better times to come. But they can’t give up. There may be only one thing in their favor, but it’s a big thing. That’s the fact that the trades a re i nd i sp en s able to ou r so c iety and offer jobs with great pay and benefits (usually). While job oppor t u n it ie s a lways f luc t u ate wildly depending on the state of the economy, they will never dry up completely, nor can they be outsourced overseas. That’s your story. Stick to it and shout it from the rooftops. W&C

LEED 2012

change will effectively do to LEED Legacy APs. At the time of this writing, more than half of the comments posted on the LEEDuser forum have to do with this proposed change.

In November 2010, the USGBC issued a LEED Rating System Draft scheduled to go into effect in 2012. This is a major overhaul of LEED rating systems for New Construction and Major Renovations, Core and Shell, Schools,

POINTS FOR BIKE RACKS

Retail, Data Centers, Warehouse and Distribution Centers and Hospitality. Several credits remain largely unaltered but there are some significant changes proposed, including some new credits, which warrant this draft version a must read for anyone involved with LEED. Although you may have missed the first deadline for public comment (at the time of this writing January 14), there is still plenty of time to get your thoughts organized and comments submitted; a second round is scheduled to occur sometime in June. To more fully engage the public in the process, the USGBC has teamed up with LEEDuser.com in establishing a forum for public comment. LEEDuser, in its opening statement on the forum’s Web page, promises to “submit all comments on the new LEED draft as public comments, on your behalf.” One advantage in using the LEEDuser forum is that USGBC employees administering the 2012 draft are monitoring the forum and occasionally respond to commenters’ posts. This is a major departure from the ultracomplicated, “black box” comment procedures employed by the USGBC in the past and offers commenters a rare opportunity for open dialogue with the rating system administrators, in real time. While not all comments receive attention, the responses that have been posted are encouraging and valuable. Below is one that I found particularly helpful from Chrissy Macken, associate, LEED Technical Development in response to a general question about what credits are fair game for comments:

42


“Every credit and prerequisite that is new or has been modified in some way (including deletion) is open for comment. All aspects of those credits are open for comment, including the referenced standards. We are trying to evolve LEED in a way that moves toward more absolute performance metrics wherever possible - giving project teams the performance goal to reach without dictating how projects get there. If you have information that can show us additional standards that will move the LEED requirements toward more absolute performance metrics, we would encourage you to proivde us with that information.” So, let’s get to some of the significant changes being proposed!

FAREWELL LEED AP LEGACY? Currently, a single rating system point is available if a LEED Accredited Professional is involved at some point in the project’s design and construction. This can be anyone (owner, architect, contractor, etc.) with any type of LEED AP credential. The proposed credit devalues LEED AP Legacy holders, barring the credential from being used to satisfy the credit requirements, and instead requires three LEED APs be certified under the new GBCI-run accreditation exams. Lots of people are going to have plenty to say about this, and will regard this as an overt move by the USGBC to make more money by requiring LEED Legacy AP holders to pay for another exam. I know of no other professional registration body that invalidates registrations in the way this proposed

LEED has taken a pretty good beating on this one, the perception being that points are awarded by the simple act of installing a bike rack on the building site. Detractors of the LEED rating system have brought this up over and again as proof of how out of whack the rating system is in rewarding points equally for this as, for example, installing an energy producing PV solar array on the roof. Never mind that this is a gross misrepresentation of the actual rating system requirements! LEED 2012 proposes no points for installing bike racks. Instead, bike racks have become a prerequisite, in an amount meeting a minimum percentage of the building’s occupants (2.5 percent of all building users in most cases as currently written).

RECYCLED CONTENT In a previous article I wrote about the relative ease in which a steel framed building would be awarded LEED recycled content points considering only materials made of steel used in the calculation. A minimum amount of recycled content material equal to the fi rst credit threshold is a now being proposed as a prerequisite. For points to be awarded above and beyond the prerequisite threshold, only “non-structural” materials will be allowed to contribute. This change will have little impact on teams for proposed prerequisite, since nearly all LEED certified buildings easily achieve the fi rst recycled content point threshold. The change will have a profound effect on a team’s ability to get any points, however, in removing structural materials from the calculation. Non-structural materials are not defined in the proposed rating system but it seems likely that “structural” materials will include concrete aggregate, steel reinforcement in concrete, cold-formed metal framing, steel

beams and columns, and steel decks. Removing these materials from the calculation will put pressure on design teams to focus on non-structural materials like interior fi nishes, gypsum board, ceiling panels, and non-structural metal framing.

BIO-BASED MATERIALS The former rapidly renewable credit has been replaced with a Bio-Based Materials credit that allows any renewable material, defined by the Farm Security and Rural Investment Act of 2002, to count toward achievement. This includes wood—non-FSC certified wood. This is sure to stick in the craw of FSC supporters, especially since the membership failed to adopt a recent proposed change to the FSC Certified Wood credit by allowing non-FSC certified wood to contribute. The credit proposes that only nonstructural bio-based materials count toward the credit. For wood-framed projects, this will be a hard pill to swallow; trusses, beams, columns, laminated timber, and structural wood sheathings will all be excluded from the calculation as proposed.

LOW-EMITTING INTERIORS This new credit lumps all of the former low-emitting materials cred-

The proposed changes to the LEED rating system are generally good, and generally moving in the right direction. its (paints and coatings, sealants, adhesives, carpet systems, and furniture) into a single, spreadsheetlike format. In addition to the previous LEED low-emitting materials, built-in casework and architectural woodwork, thermal insulation, and acoustic insulation have been added to the list. Points are awarded for a percentage of these materials that are tested in accordance with the California Department of Public Health Method V1.1-2010. The big deal about this credit, in the way it is currently presented, is that fractions of points from different material categories can be combined with one another to make full points. The current rating system is an all or nothing approach—if one product or material is less than the required allowable emission thresh-

old, all is lost. This is one of the best ways to kill incentive to pursue a credit. The proposed credit will hopefully pave the way for this revision to be made to all other credits, eliminating the arbitrary thresholds and incentivize teams to pursue as much of every credit possible, and be rewarded for the effort.

CONCLUSION The proposed changes to the LEED rating system are generally good, and generally moving in the right direction. LEED 2012 in its fi rst draft is unrefined and loosely written. This is a good thing, I think, because it provides an opportunity for public comments to better shape the rating system into a highly refined, well-crafted document. And it couldn’t be easier to do so with the establishment of the LEEDuser forum. I will be submitting my comments soon and I encourage you to do the same.

Knockdown texture repair tool TEMPLATE LLC

The TriSys three-frame system offers premium features from finishing and assembly to overall design and performance. The system features a millwork-inspired, homeowner-preferred profile as well as a clean aesthetic design with no screw hole plugs. The frame’s new FiberMate material has the best paint and stains adhesion rating possible and allows the frame to have a dark finish without the risk of deformation due to heat. No special primer or preparation is needed. Assembly and service are made easy with a number of innovative features. The frame system screws together easily and includes a third piece that snaps on, eliminating the need for screw hole plugs and allowing for easier finishing and a more visibly appealing and cleaner aesthetic. The pin alignment system ensures rapid and accurate alignment of frames and the precision-applied dry glaze seal will not squeeze out. These features allow for easy adjustments and removal, resulting in less time spent on field replacements.

The Drywall Repair Tool is a flexible plastic template with a random knockdown pattern that enables the user to replicate the knockdown texture on the rest of the wall after a drywall repair has been made, using the template, joint compound and a putty knife. The process is much cleaner and faster than using a professional sprayer or a retail spray can treatment because there is no over-spray and no need to tape off the area to protect the surrounding surfaces. The benefit to drywall professionals is that they can make multiple repairs more quickly after contractors have completed their work, and move on to other paying jobs faster. Professional contractors, maintenance professionals and installers of home theater, fire and security systems can use the repair tool to complete drywall repairs for their clients without having to bring in a drywall contractor or leave the mess behind for the client to repair. The tool can be re-used on multiple projects, making it extremely cost-effective for those who perform frequent drywall repairs.
