Working Together for a Sustainable Future
Creative Ventilation Breathes Potential into Rec Center

By Dr. Don McLean
By Glenn Carels, AIA, LEED AP
The “Passive House for New Orleans” challenge engaged the AEC community in developing a series of affordable, low-energy homes for neighborhoods in New Orleans that are still recovering from Hurricane Katrina.
Architects and engineers used to focus on one thing — production. Then the world started to become more energy conscious. How can architects and engineers work together to measure and improve the overall functionality and energy efficiency of buildings?
A southwest-facing concrete wall layered with glass is one of the reasons the Wellness and Recreation Center at California State University East Bay runs without an active heating system.

EDITOR’S
NOTE International Intrigue This year is the first that USGBC has taken its marquee tradeshow past U.S. borders. Taking the Greenbuild International Conference and Expo abroad shouldn’t come as much of a surprise given the organization’s intent to export its LEED rating system across the globe. I’ve heard a few complaints from some U.S.-based individuals about the added difficulty of having the show in another country, but this step by USGBC is one that many organizations committed to sustainability are taking. Codes, standards, rating systems and other “benchmarks” relating to sustainability are often being created and updated, and a couple of major international organizations have levied their own creations since 2010: ICC and ISO. While the respective creations of IGCC and ISO 50001 aren’t necessarily turning points for sustainability, they exemplify sustainability as a growing trend worldwide. Because enough governments, groups and companies are paying heed to the benefits of environmentally friendly design across the globe (whether or not all of them truly care about the environment is moot), it made sense to create international standards as a sort of Rosetta Stone for green building.
is better simply because anything has to be better than what’s going on in your country. But when you delve into the sustainable practices of other countries, you’ll find that they aren’t necessarily better or worse: They’re just different. The differences can take many forms and be because of less quantifiable reasons like culture. And it’s safe to say that what works in one country might not work in another. The U.S. has that problem within its own borders. Breaking out of the comfort zone and taking a step beyond a defined territory, like what USGBC is doing with Greenbuild or like the introduction of international green codes, gives us all a chance to discuss what sustainable design is and what it means to us. It creates an opportunity to teach others and learn from them at the same time. It’s a chance to share experiences, develop relationships and create a stronger global community focused on redefining the built environment. On some level, green speaks to us all. Reaching out to the world is a great way to get the conversation started, even if the act of reaching out might be an inconvenience. So, whether or not you like having the show in another country, spreading sustainability to neighboring countries and abroad is a necessity.
The Language of Green At face value, it’s easy to fall into the trap and go in with the preconceived notion that what you and your country do is better — and this doesn’t only apply to North Americans going abroad. I’m sure plenty of people from other countries coming here have fallen into the same trap. To that end, I’m sure lots of people might believe that what’s going on in another country
Cheers,

In 2008, ED+C and Sustainable Facility magazines embarked on an online awards contest that gives manufacturers a chance to see how their products stack up in the eyes of our readers. Readers are asked to vote for products that they feel offer the best combination of sustainable attributes with ease of use and installation in a variety of categories. THE WINNERS FOR THE 2011 COMPETITION ARE LISTED BELOW. MATERIALS WERE SUBMITTED BY THE COMPANIES.
CATEGORY: ALTERNATIVE ENERGY SYSTEMS Product: DRIQ Manufacturer: BuildingIQ BuildingIQ’s DRIQ is an Optimized Demand Response (DR) product that automates and optimizes a building’s response to DR events.

nvironmental responsibility is a primary value for the Bend Park & Recreation District, and it was a critical element in the design of the LEED Goldcertified administration building by Opsis Architecture. The project offers a demonstration of how manmade and natural elements can be brought together to blur the boundaries of indoor and outdoor spaces while promoting environmental stewardship. Bend Park & Recreation District’s administration building is ED+C’s Excellence in Design Government category winner. The new administration building, located on a 14-acre park in Bend, Ore., provides office space for current staff and allows for the department’s anticipated growth over the next twenty years. In keeping with the Bend Park & Recreation District mission, the administration building project is committed to sustainability

and respect for the surrounding landscape. Mixing the indoors with the outdoors was integral to the overall design. “Early in the design process the building committee outlined its desire that the facility respect and integrate with the beautiful riverfront site,” says James Meyer, partner at Opsis. The site, in the Old Mill District area, was selected due to its visibility and central location; both were ideal for serving the community and the district at large. “Maintaining a tie to the architectural fabric of the Old Mill District, the building’s design is
intended to present the visitor with a friendly and welcoming ‘park-like’ experience,” says Jason Miller, senior associate at Opsis. “Public indoor and outdoor spaces were important features to the overall design, making this building within the park a hub for community congregation and local events. The facility’s design is intended to demonstrate the district’s progressive values of environmental and community stewardship, with humble regional charm and a truthfulness of expression.”
In an effort to respect the landscape, existing trees and groundcover were maintained as much as possible. The administration building project preserved 377,836 square feet of vegetated open space, 345 percent more than is required by the local zoning code. The project also included the restoration of the native habitat along the Deschutes River. Onsite stormwater is collected, treated and infiltrated by an expansive 6,000-square-foot green roof, a series of bio-filtration basins and rock trenches designed for infiltration. “Personally, my most favorite sustainable design feature is the green roof,” says Miller. “Located over the portion of the building which houses the public areas, including the lobby and large community room, this broad lower roof plane tilts upward, increasing access to river and mountain views from the interior. But perhaps more importantly, the angle of the roof exposes

In a real sense, it provides the community with a learning opportunity in sustainable systems.” In addition to using native plantings in the landscape, the project employs a drip irrigation system to reduce water use. Waterless urinals and low-flow fixtures further reduce water use within the building. These efforts result in a water savings of 45 percent, or approximately 85,500 gallons every year. “Another key feature in the project is the specific building response to the site orientation,” says

Meyer. “The north building façade is composed primarily of solid, highly insulated walls with limited glazing areas. On the south side, the building’s glazed walls open to spectacular views to the river and allow sun to penetrate deep into the office spaces while providing summer shading through the use of exterior trellis components.” Besides providing energy efficiency, the orientation of the building also supplies a sense of organization. “One of the most challenging features of the project was to design a facility that invited the community to use the building while at the same time created highly func-
tional office space,” continues Meyer. “This was accomplished by organizing the uses in a manner that allowed office portions of the building to be closed while community activities in other areas could be going on. To this end, the western portion of the building contained the large community room, fireplace lounge, restroom facilities and the large outdoor terrace. Two main entries were created — one from the south and one from the north — to further offer easy access to the community.” Thirty-seven percent building energy efficiency is achieved through the building en-
velope and mechanical systems. The high thermal performance exterior envelope is paired with a mixed-mode natural ventilation system, radiant/chilled floor slab for heating and cooling, two high-efficiency condensing boilers, a solar hot water system, and energy-efficient lighting with occupancy and daylight sensors. Due to the radiant floor system, though, not every step of the design process was blue skies. “Probably the greatest challenge presented to the team came during the LEED construction submittal review in which the Energy and Atmosphere (EAc1) prerequisite credit was denied,” says Miller. “This was due primarily to the complexities involved with modeling a radiant system, which yielded results that could be falsely interpreted in the energy model. Without satisfaction of this prerequisite, project LEED certification would
not have been possible. To address the issue, the team provided information to address the reviewer’s issues primarily concerning fan power, system zoning, outside air rates and heating energy consumption. In addition, the energy model was modified to make the baseline and proposed cases function as accurately as possible to the applicable system types. The project was ultimately awarded
LEED-NC v2.2 Gold certification with 43 points.” These efforts are estimated to result in an energy cost savings of more than $29,000 a year. Additional energy consumed by the building is supplied by green power. Construction waste for the project was tightly managed, allowing more than 88 percent, or 159 tons, to be diverted from landfills. Juniper trees onsite that had to be removed during
the project were harvested, milled onsite and reused as custom juniper woodwork in the building’s interior. From the structural steel to the toilet partitions, the building incorporates a significant amount of recycled materials. Based on cost, 19 percent of the materials used on the project were recycled, reducing the impacts that result from the extraction and processing of virgin materi-

als. The selection of local materials was also a high priority for the project, reducing the impact from transportation and supporting the local economy. More than 40 percent of the materials used in the project were extracted, processed and manufactured within 500 miles of the project site. Door frames, stair treads and casework are made from bamboo, a rapidly renewable resource. Extensive daylight and views contribute to the indoor environmental quality of the administration building. Natural ventilation enhances the indoor air quality and allows building occupants a high degree of control over their thermal comfort. Low-VOC adhesives, sealants, paints and carpets were also used to maintain the air quality. “Through this process an entire community has felt a sense of ownership and a satisfaction that the mission of stewardship is represented in the area’s first public LEED-certified building,” says Meyer. Miller agrees. “When client satisfaction is transcended and a real sense of pride and ownership develops, that’s one of the highest complements an architect can receive — you know you got it right.” The above information was provided by Opsis Architecture.

Principles to Design By Three proven economic principles are put into practice on Sustainability Base: lean, mean and green. Lean is the practice of using the least resources possible, mean is the method of achieving highest output using low-cost/passive strategies, while green exploits renewable power generation to its greatest capacity with regard to human health. Keeping these three principles in mind, the project team was able to achieve a net-zero facility that is projected to save approximately $30,000 per year in energy savings. Without roof-mounted solar panels, Sustainability Base achieves 87 percent better energy performance over ASHRAE 90.1 and goes beyond 100 percent with the panels.

hile NASA’s shuttle program has come to an end, other, more earthbound NASA programs are just beginning. The goal of one new program, Renovation by Replacement (RbR), aims to achieve sustainability by replacing dated, inefficient buildings with new, high-performance ones. Building N232, otherwise known as Sustainability Base, was the first to undergo transformation on the 213-acre NASA Ames Research Center. This new 50,000-square-foot office, research and conferencing facility — created through a partnership between AECOM, William McDonough + Partners, Loisos + Ubbelohde, and collaboration with NASA’s researchers and consultants — is “a lunar landing station on earth.” As the first building in 20 years to be built at NASA Ames Research Center, it was likely going to have the smallest environmental footprint and be a healthier work environment than any of the other buildings on the campus. But, in the spirit of exploration, the project team took Sustainability Base further. The result is a building that sets the tone for a change-management process focused on building a sustainable campus infrastructure.
achieve LEED Platinum. The radial plan references the sites’ circular driveway access, while the narrow depth of the building, 55 feet, enables operable windows on both sides to take advantage of the local climate for natural ventilation and daylighting. AECOM’s June Grant, project manager for Sustainability Base, says that the key to the building’s achievements was an understanding that the whole comprises the parts. “There is a tendency to view sustainable design as a list of features,” says Grant. “In fact, for buildings with high goals, such as Sustainability Base, these features must operate as an integrated unit. On average, AECOM and consultants estimated as a base case before green features, NASA Ames’ energy use for per California Code ASHRAE Standard 90.1 energy consumption would have been 850 mWh and 1 million gallons of potable water per year respectively. As a result of an integrated approach, energy use is expected to be net positive at approximately 200 mWh/year, and water consumption should be reduced by approximately 87 percent.” Grant goes on to explain that the engineers on the project undertook a great deal of simulating and prototyping to optimize the strategies used to tie systems together, including façade performance, daylighting and interior electric lighting. And it was through this analysis that some problems with the desired design solutions were found. “Initially, the desire was for a fully naturally ventilated building,” she says. “However, analysis showed a case for zero air-conditioning was not practicable. During peak summer, interior temperatures would have peaked at around 97 F, and it was estimated that 16 days of a year would be lost. “As a result, Sustainability Base is designed with a mixed-mode ventilation system. Operable windows will allow the building to be cooled naturally and, when necessary, augmented by a chilled ceiling and underfloor air distribution system.”

That idea was abandoned for noncompliance with structural code since the base is required to meet high structural and safety standards similar to emergency services. But the idea of creating a long-lasting structure with reuse possibilities, as well as achieving a higher performance life-safety level, stuck. That idea led to a unique solution. “One of the most visible aspects of the new facility was its innovative steel-frame exoskeleton, which required close coordination between the architects and structural engineers, who utilized Revit Structure software,” says Grant. “Revit Architecture, in tandem with Revit Structure, enabled transparency in identifying structural changes which impacted the architecture.” The exoskeleton offered structural support, while also supporting other goals. It allowed the architectural and engineering team to maximize daylight and natural ventilation and helped to create a column-free interior for flexible space planning. Additionally, the structural system relates to the history of other NASA structures.

And given that research is part of Sustainability Base’s function, it was an opportunity to learn more about the building and how its systems perform. “Like the old Intel advertisement,” Grant says, “the heart of Sustainability Base is the diagnostic devices which have been installed into the building. NASA research such as the Forward-Osmosis Water Recycling System, Intelligent Control Technology and Prognostics devices will provide continuous data about the building from which NASA will be able to monitor and fine-tune its performance.

T
he devastation caused by the Great Depression is well documented. Almost equally well documented is the New Deal that helped pull the country from that dark time. In Oklahoma, the Works Progress Administration (WPA) was formed to help Oklahoma families through work projects. Among the work projects bolstered by the WPA was the creation of armories for the Oklahoma National Guard. In all, 51 armories were created during the 1930s — the most of any state. Now, these aging facilities are being replaced to meet modern needs. The creation of seven larger Armed Forces Reserve Centers (AFRC) allows for fewer structures throughout the state while meeting the demanding needs of the National Guard and Army Reserves who provide military readiness, community disaster relief and civic function. One of the new high-quality facilities meeting the needs of today’s military is the AFRC in Muskogee, Okla. The 97,000-square-foot reserve center was constructed to LEED Silver certification and has been designed to include more than 450 National Guard members and Army Reserve soldiers. It includes training areas, a drill floor, arms vaults, administrative areas, a kitchen and classrooms. HEAT GAIN WAS A MAJOR CONCERN DURING THE DESIGN OF THE MUSKOGEE AFRC AS THE BUILDING FRONTAGE FACES THE HARSH WESTERN SUN.

BUILDING INFORMATION MODELING HELPED THE DESIGN TEAM TO ADDRESS POTENTIAL PROBLEMS BEFORE THEY OCCURRED, ESPECIALLY WHEN COORDINATING TRADES.
Instead of forgetting the area’s past, the design harkens to those public works projects of the 1930s. The Haskell Company’s Alan Wilson, AIA, design principal for the design-builder of the Muskogee project, explains, “Consistent with the old armories, the building features a stone front with a limited number of small vertical windows facing west. (The windows are high-efficiency glazing.) The plan is organized so rooms that required few or no windows are placed

on this elevation, such as the mechanical rooms flanking the main entry portion of the western elevation. The offices and classroom spaces, which required greater expanses of glass, were shifted in the plan to the north and south sides of the building. In these orientations, windows received little solar heat gain (north), or the sun could be controlled by sun-shading devices (south). This was just one of the project’s sustainable features that allowed the facility to be recently certified as

to the architectural design and structural engineering. The three-dimensional models enabled greater coordination between the trades and helped find resolutions to potential conflicts before work occurred in the field. “There were numerous other advantages to the BIM model as well,” Wilson says. “At complicated intersections of building components, such as the tilt-up concrete panels used as both the back-up and ‘trim’ for the stone veneer, three-dimensional ‘snapshots’ of the model were incorporated into the 2D drawing package. These 3D images illustrating the intersections of components were far more legible and useful in the field than their traditional two-dimensional counterparts. A model

The facility honors the historical precedent and offers a sustainable solution at the same time.” Wilson adds that the building’s layout and solar orientation was in response to one of the most challenging aspects of the facility’s sustainable design. “The primary building façade faces the highway toward harsh western sun,” he says. “This posed an inherent conflict between the need to have a high-quality building front with a positive street presence and the desire to minimize glazing in this direction in order to limit solar heat gain.”
Modern Methods Building information modeling (BIM) played an integral role in the Muskogee AFRC’s development. Revit technology was used to design the facility, which allows the client to view a 3D representation of the completed project and allows the design team to identify modification needs early. The technology was particularly helpful on this project as it allowed Haskell to incorporate the mechanical and electrical aspects of the job in addition

was also utilized for layout of tilt-up panels and ‘followed’ the erection of the building itself so one could view the state of progress on the building simply by seeing the current state of the model.” But what anyone who passes the facility can see is a structure that recognizes the historical importance of its forebears while addressing the current and future needs of those who occupy it. And, as Wilson says, it was all just a matter of making the client happy. “The sustainable measures, technology employed and overall design-build process were all in service of providing a high-quality facility to meet the functional needs and desired image for the National Guard and Army Reserves. Working together as a team, both internally as design-builder and with the client, the new Muskogee Reserve Center accomplishes these objectives and is well-liked by the users.” DERRICK TEAL IS EDITOR OF ED+C.

Have you ever been denied a building permit based on your project’s energy performance? Very likely, the answer is “not yet.” Documenting energy performance metrics to show code compliance with ASHRAE’s 90.1-2010 or California’s Title 24, Part 6-2008 just isn’t something many architects include in their typical scope of work. But
meeting code requirements that include performance-based energy requirements — as part of the building code — will force a change in the status quo. Even if you have designed LEED Platinum-certified buildings, very few architects really appreciate what MEP engineers and energy modelers do when they walk behind the energy modeling
curtain and return after much time and effort with “the number” that determines whether or not the design is in compliance with the applicable energy code. Why should architects want to change the design process to more substantively incorporate energy models? After all, aren’t architects trained in the fundamentals of building sciences as part of our
