Campus Showcases High-Performance Buildings
Press release date: Jun 09, 2014
The recent construction on the NREL campus was a significant undertaking, in which integrated project teams from a wide variety of disciplines—construction managers, sustainability professionals, and building research engineers, to name a few—focused on the design and construction of innovative facilities that would meet the needs of a growing laboratory while also meeting ambitious energy performance requirements.
"Energy has not been a foremost consideration on similar projects. They look at scope, schedule, and budget; then when the design is done, they determine how much power they need," said NREL Deputy Director for SITE Operations Drew Detamore, who led the campus development efforts. "Here, we added energy to the decision-making process from the beginning. Every decision that was made along the way took into consideration the impacts it would have on the energy model for the building."
In order to ensure that energy performance goals could be met, NREL developed a unique performance-based design-build approach to partner with design, engineering, and construction industry leaders on the projects. The design-build approach incorporated rigorous project controls and methodologies to provide NREL with facilities that featured best-in-class energy efficiency and sustainability practices.
"The design-build approach with our project partners was critical to the process," Detamore said. "We came into it focused on what we wanted projects to do over what we wanted them to be, and the design-build approach allowed that line of thinking to work effectively. You have to place a priority on performance over design, and then you can do what we've done at NREL. You must have strong project-management people involved who understand the process and are willing to let go of the design. As a result, we have buildings that meet all of our performance goals, are well designed, and happen to be very attractive."
Developing a high-performance, sustainable campus at NREL to serve as a highly productive environment that would support the mission of the laboratory was important. NREL also wants its campus and buildings to serve as a model for how commercial buildings and campuses should be built and to be a tool to help show others how.
"Our goal is to provide leadership to both the public and private sectors to show that this can be done, it is being done, and here's how you do it," NREL Senior Energy Efficiency Research Engineer Shanti Pless said. "We've made these buildings as efficient as possible and have learned a lot along the way. We want to share those lessons learned and best practices with the buildings industry to facilitate the movement of this type of design and construction into the mainstream."
All design and construction on the NREL campus used strategies and materials that are available to anyone. All products used are off-the-shelf and could be accessed for any building. Implementation of similar design-build techniques could be done on any project anywhere. The most important piece of the puzzle is to apply good technologies, along with a solid planning and design process, and integrate them effectively to work well together.
"These buildings are highly replicable," Pless said. "A project developer can take what we've done here and apply it in the marketplace. It performs as promised, is cost effective, maintainable, and marketable. These results combine to make energy-efficient buildings very approachable in any environment."
To facilitate the continued growth of energy-efficient and zero-energy building projects everywhere, NREL regularly hosts visits to its campus by project developers, architects, builders, and other commercial building industry professionals. These visits give NREL an opportunity to show firsthand what these buildings can do, how they perform, and how they can be replicated.
"When we show this to people they can quickly begin to visualize how they can replicate it, and by doing that we are having a meaningful impact on the commercial buildings industry," Pless said. "Proving it can be done is an important step. It is one thing to say you can do it, another entirely to prove it and demonstrate it. Here at NREL we've done just that."
The campus also provides NREL research staff with opportunities to validate their research in a real-world environment with occupied, operational buildings in an effort to quantify and maximize building performance.
Researchers in NREL's Commercial Buildings research program have installed meters in all new buildings and are collecting a massive amount of performance data. They are now developing tools that can put this data into action to the benefit of building developers and operators everywhere.
"We are trying to align building decision makers with the data that we are collecting," Pless said. "By creating useful tools to help them take advantage of building data, we are providing them with the critical information that they need to make good decisions that will further enhance building performance and occupant comfort."
NREL has developed a new tool called the "NREL Energy Story" that serves the dual purpose of telling the story of NREL's sustainable campus to the public as well as serving as a management tool that allows NREL engineers to analyze campus energy performance in real time and identify problems quickly.
"We've essentially created an energy management tool for our campus with an education component layered into it," said NREL Strategic Energy Analysis Center Principal Project Lead Mark Ruth. "It allows us to improve our story at the same time we are telling our story. It's a one-of-a-kind tool that provides great benefit both internally and externally."
The tool is a real-time visualization of energy production and consumption on the NREL campus. It includes modules for electricity, heating and cooling, and fuels. It provides a big-picture view of the entire campus, as well as detailed analysis of specific areas such as lighting or plug loads within a section of a building. For the public, it compares NREL's campus energy use to that of a typical campus that lacks the type of high-performance buildings found at NREL. It also includes a series of infographics that can show users what the potential impacts and cost savings of energy efficiency applications could be for the nation, or for a home.
"This tool helps the public understand the impact of their energy choices, which will hopefully guide their decision making in the future to use energy more wisely," Ruth said. "We strive to be a ‘living laboratory' here at NREL, and this tool helps to bring this to life in a way that everyone can understand. It clearly demonstrates how the lab improves its own energy use and the potential benefits others can realize if they to implement these strategies in their homes or communities."
Recently, at a dedication ceremony held on the NREL campus, the U.S. Green Building Council (USGBC) recognized NREL's efforts with Leadership in Energy & Environmental Design (LEED®) Platinum certification for three of its newest campus facilities, including the recently opened Energy Systems Integration Facility (ESIF).
The USGBC's LEED® program is a green building certification that recognizes best-in-class building strategies and practices. Building projects must satisfy prerequisites and earn points to achieve different levels of certification. A Platinum certification is the highest level in the program.
In addition to the ESIF, the USGBC also recognized NREL's new Café and South Site Entrance Building for achieving Platinum status. With these new certifications, NREL can now lay claim to six LEED® Platinum certified buildings on its Golden campus, including the award-winning Research Support Facility, which was recently verified to have performed for a full year as a net-zero energy building.
"We are extremely proud of the campus we have designed and built here at NREL and the recognition that we have received for our efforts," said NREL Deputy Director and Chief Operating Officer Ken Powers. "This campus will provide our world-class research staff with the resources and facilities they need to support our clean energy mission, as well as serve as an example of how these technologies and strategies can be effectively applied."
Sustainability as a Core Value
NREL is a recognized leader in sustainability, with practices that are incorporated into the mission and fully integrated into all facets of the operation of the laboratory. When planning the design of the NREL campus, it went without saying that sustainability would be a key consideration.
Sustainability professionals were part of all integrated project teams throughout the process, and efforts to make the NREL campus as sustainable as possible guided every decision. The use of sustainable building products, technologies, and practices helped to garner the points necessary to achieve the LEED® Platinum certification for all new buildings.
"We underwent a lot of growth in a short period of time, and all of the people involved in making that happen adopted the mission and value system of the laboratory in regards to sustainability throughout the process and never lost focus on it," NREL Sustainability Program Director Frank Rukavina said. "It makes our job, as sustainability professionals, a lot easier when everyone involved understands the priority and is on board from the beginning to make these building projects as sustainable as possible."
Examples of sustainability practices incorporated into the new buildings are numerous. For the newly Platinum certified buildings, these include comprehensive recycling and composting programs, native and xeriscape vegetation, locally sourced food for the new cafeteria, water conservation efforts for the commercial kitchen in the new cafeteria, storm water recycling strategies, and building materials made of recycled materials.
"Everyone looks to NREL to be a leader on these issues now and in the future. We have a responsibility within our basic mission to set the best possible example and to be a model for what a campus could be and should be," Rukavina said. "We've excelled because we've committed to it and we've created a campus that showcases our mission and our values as an organization. We have a population here at NREL that takes energy efficiency and sustainability personally and seriously. This drives us to continued excellence and challenges us to always be as sustainable as we possibly can."

Beyond LEED® — The Net-Zero Energy Research Support Facility
As the Energy Department's National Renewable Energy Laboratory (NREL) celebrates the certification of three new LEED® Platinum buildings, bringing the total number of Platinum certified buildings on its campus to six, another important milestone on NREL's sustainable campus was also achieved: NREL's Research Support Facility (RSF) recently completed a verified one year of performance as a net-zero energy building.
A net-zero energy building is one that, over the course of a full year, produces more energy than it consumes.
The RSF, a LEED® Platinum certified 360,000-square-foot Class A office building that houses approximately 1,300 NREL and Energy Department staff as well as a data center, accomplished this through a combination of energy efficiency technologies used in the building, effective operations and management of the building, and onsite electricity generation from a 2.6-megawatt solar photovoltaic (PV) system on the roof of the building and adjacent parking areas.
"We made a commitment to design and build a building that could reach net zero in operations," NREL Senior Energy Efficiency Research Engineer Shanti Pless said. "The design-build team delivered to us a well-designed, well-engineered, and well-constructed building that was able to support that goal. With the addition of the PV system we felt that we could successfully offset all of our annual energy use. Through active energy management and real-time benchmarking tools, we're very proud that we were able to achieve this important milestone."
Like the rest of the NREL campus, the RSF was designed and built with the intention of being a model for how building projects can incorporate energy efficiency strategies and technologies, and in the case of the RSF how projects can be made to be net-zero energy ready. The NREL researchers involved in the project made it accessible to anyone by compiling and documenting their experiences in energy performance-based commercial building acquisition and the adoption of energy-saving building technologies.
"There's a growing interest in net-zero energy buildings now that it is getting more cost effective and the industry is beginning to understand it better," Pless said. "The cost of PV and energy-efficient building materials like LED lighting have come down dramatically in the last few years, and that has made the idea of building for net zero much more approachable. As a result, there is an expanding level of expertise and capability out there for delivering buildings for net-zero energy operations. This is still cutting edge, but it is scaling up and heading toward the mainstream."
NREL is a consistent leader in bringing high-performance, energy-efficient building projects to life on its campus. In 2006 NREL laid claim to having the only LEED® Platinum federal building with its Science & Technology Facility. Today, LEED® Platinum federal buildings are becoming commonplace, including six on the NREL campus alone. Now, NREL again demonstrates its leadership by being the home of the very first federal building verified to achieve net-zero energy performance. However, unlike a green building certification that happens once, net-zero energy is something that is ongoing and must be achieved annually.
"One of the great things about net-zero energy is that it's an operations target, not a design target, that requires ongoing management to reach from year to year," said Pless. "This keeps our building managers, engineers, and occupants constantly thinking about how we use energy and seeking ways to improve our performance. We'll need to keep doing that to assure that the building meets net-zero energy operational goals year after year. We look forward to that opportunity."
