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.”

A feast of dining options at University of Colorado community center, but hold the buffalo stew
The University of Colorado, Boulder, cooked up something different with its new $84.4 million Center for Community building, whose 900-seat foodservice area consists of 12 micro-restaurants, each with its own food options and décor. Centerbrook Architects of Connecticut collaborated with Denver’s Davis Partnership Architects and foodservice designer Baker Group of Grand Rapids, Mich., on the 323,000-sf facility, which also includes space for a career center, international education, and counseling and psychological services. Exterior walls of rough-hewn, variegated sandstone and a terra cotta roof help the new facility blend with existing campus buildings. Target: LEED Gold.

Chicago high-rise mixes condos with classrooms for Art Institute students
The Legacy at Millennium Park is a 72-story, mixed-use complex that rises high above Chicago’s Michigan Avenue. The glass tower, designed by Solomon Cordwell Buenz, is mostly residential, but also includes 41,000 sf of classroom space for the School of the Art Institute of Chicago and another 7,400 sf of retail space. The building’s 355 one-, two-, three-, and four-bedroom condominiums range from 875 sf to 9,300 sf, and there are seven levels of parking. Sky patios on the 15th, 42nd, and 60th floors give owners outdoor access and views of Lake Michigan.

Iowa surgery center addresses both inpatient and outpatient care
The 12,000-person community of Carroll, Iowa, has a new $28 million surgery center to provide both inpatient and outpatient care. Minneapolis-based healthcare design firm Horty Elving headed up the four-story, 120,000-sf project for St. Anthony’s Regional Hospital. The center’s layout is based on a circular process flow, and includes four 800-sf operating rooms with poured rubber floors to reduce leg fatigue for surgeons and support staff, two substerile rooms between each pair of operating rooms, and two endoscopy rooms adjacent to the outpatient prep and recovery rooms. Recovery rooms are clustered in groups of four. The large family lounge (left) has expansive windows with views of the countryside, and television monitors that display coded information on patient status so loved ones can follow a patient’s progress.

Two projects seek to reinvigorate Los Angeles County medical center
HMC Architects designed two new buildings for the Los Angeles County Martin Luther King, Jr., Medical Center as part of a $360 million plan to reinvigorate the campus. The buildings include a 120-bed hospital, which involves renovation of an existing tower and several support buildings, and the construction of a new multi-service ambulatory care center. The new facilities will have large expanses of glass at all waiting and public areas for unobstructed views of downtown Los Angeles. A curved glass entrance canopy will unite the two buildings. When both projects are completed—the hospital in 2012 and the ambulatory care center in 2013—the campus will have added more than 460,000 sf of space. The hospital will seek LEED certification, while the ambulatory care center is targeting LEED Silver.

Sustainable community center to serve Angelinos in need
Harbor Interfaith Services, a nonprofit serving the homeless and working poor in the Harbor Area and South Bay communities of Los Angeles, engaged Withee Malcolm Architects to design a new 15,000-sf family resource center. The architects, who are working pro bono for the initial phase, created a family-centered design that consolidates all programs into a single building. The new three-story space will house a resource center, food pantry, nursery and pre-school, and administrative offices, plus indoor and outdoor play spaces and underground parking. The building’s scale and setbacks will help it blend with its residential neighbors, while its low-flow fixtures, low-VOC and recycled materials, and energy-efficient mechanical equipment and appliances will help it earn LEED certification.
