Center for the Built Environment (CBE)University of California at BerkeleyA National Science Foundation Industry/University Cooperative Research Center since 1997Innovative building technologies will improve the environmental quality, energy efficiency, and workplace productivity of commercial buildings Center Mission and RationaleImproving the quality of indoor environments and enhancing the energy performance of commercial buildings could lead to productivity gains and operating cost reductions worth hundreds of billions of dollars in the U.S. alone. Despite this huge potential, building research as a percentage of sales is well below that of other industries. In May 1997, a group of industry and government leaders teamed up with faculty and researchers at the University of California, Berkeley, to address the challenges of creating high-quality buildings. The result was the Center for the Built Environment (CBE), with the mission of providing timely, unbiased information on promising technologies and creating a dynamic, collaborative setting where people can develop ideas for improving the design and operation of commercial buildings. Research ProgramCBE conducts a variety of building research projects, ranging from the evaluation and development of new building technologies that reduce energy use, improve environmental quality, enhance occupant comfort, and increase productivity, to tools that "take the pulse" of buildings in operation, enabling everyone in the building process to learn how a building actually performs in practice. Current and recent CBE research includes:
Since the building industry involves a mix of disciplines, professions, and physical processes, an interdisciplinary approach is essential. CBE draws upon the expertise of 15 faculty in six departments across the UC-Berkeley campus, as well as staff scientists at Lawrence Berkeley National Laboratory and full-time in-house research specialists. Fourteen students are currently assisting the Center in carrying out its research. In addition to participating in the Industry/University Cooperative Research Centers Program, CBE researchers are active in the following:
Special Center ActivitiesDuring the past two years, many of CBE's projects have produced significant results. The following projects have publicly disclosed findings:
A core strength of CBE is that its membership mirrors the diversity of the building industry. All of CBE's members plan to use advances developed by CBE in their businesses. FacilitiesMost of CBE's facilities are housed at the UC-Berkeley College of Environmental Design. CBE's equipment and instrumentation includes a Controlled Environment Chamber, designed to resemble a contemporary office while allowing precise control over the temperature, humidity, ventilation, and lighting in the space; a Boundary Layer Wind Tunnel, which simulates the natural wind over models of the built environment in order to predict wind effects at full scale; a unique segmented thermal manikin for studying thermal comfort and environmental control provided by building systems; and an instrumented cart that makes detailed measurements of the physical environment from ankle level to head height. The Center also has a wide array of portable equipment for acquiring and analyzing data from experiments in the field as well as in the laboratory, including infrared thermographs, heat flux meters, flow metering hoods, tracer gas systems, flow visualization systems, electric power meters, instrumentation for measuring the detailed thermal and luminous characteristics of building interiors, and portable weather stations for measuring exterior microclimates. Shared and/or off-site facilities include a full-scale testbed underfloor air facility; sky simulators for modeling daylight in buildings (developed with Lawrence Berkeley National Laboratory with funding from the U.S. Department of Energy); and a large Heliodon with a collimated beam and a miniature point-of-view video camera for analyzing solar access and shading (developed with the Pacific Energy Center, San Francisco).
