Dissatisfied with the one-dimensional nature of defining energy efficiency as it relates to commercial buildings, international engineering firm Buro Happold developed a metric that links energy use to economic performance. The Building Economic Energy Coefficient (BEEC) could help many commercial building owners whose properties use a lot of energy (input), but add economic value to their cities and regions (output). This metric can also be a game changer that influences how local governments create policy to monitor the energy use of buildings.

Most systems of measurement deem a building efficient or inefficient based solely on how much energy it consumes. By contrast, BEEC measures a building’s energy use against economic performance indicators to give a more complete picture of a building’s productivity -- hence its overall efficiency. For example, a building might use less energy, but its tenants do not contribute as much to the regional economy. By this definition, another building that uses more energy might have an exponentially greater economic performance, making it more efficient.
When observed from this more comprehensive vantage point, some buildings that were previously thought of as energy hogs are revealed to be using energy more efficiently than many low-energy buildings. Buro Happold used proprietary research from CoStar Group to determine economic performance of commercial buildings in New York.
“Energy efficiency is framed in a very black-and-white way – either a building has low energy intensity or it is considered wasteful. With this research, we can now see whether or not commercial buildings are putting energy to good use. It allows us a much more nuanced and complete picture of what’s really going on with energy use,” said Steven Baumgartner, PE, CEM, HBDP, LEED AP, associate at Buro Happold, who led the research team, along with Jim Coleman and Amelia Aboff of Happold Consulting, Buro Happold’s strategic consulting arm.
City officials, building owners, and members of the AEC industry measure a building’s energy use on a per square foot, per year basis. This is known as its Energy Use Intensity (EUI). EUI is a very useful metric in determining a building’s performance but it only tells half of the story.
“Buro Happold has been a pioneer in sustainability for decades, and now we are intensively involved in the challenges of the 21st century,” said Craig Schwitter, PE, BSCE, MSCE, principal. “We are a multidisciplinary firm that brings a comprehensive approach to problems at multiple scales – from the individual building to the region. This groundbreaking research will have a major impact on the way that energy use is discussed and regulated as we meet the ongoing challenges of an increasingly complex world.”
BEEC data is currently limited to New York City commercial buildings. With more funding, Buro Happold hopes to expand the scope of the research to include more cities, and with greater detail. “This is a huge first step toward redefining energy efficiency,” added Baumgartner, “and we’re excited to take this research to the next level.”

New Urbanist Andrés Duany: We need a LEED Brown rating
Andrés Duany advocates a "LEED Brown" rating that would give contractors credit for using traditional but low cost measures that are not easy to quantify or certify. He described these steps as "the original green," and "what we did when we didn't have money." Ostensibly, LEED Brown would be in addition to the current Silver, Gold and Platinum ratings.
