Creating low-energy commercial buildings through effective design and evaluation
This paper presents two case studies of passive solar commercial buildings that were designed and constructed at the National Renewable Energy Laboratory (NREL) in Golden, Colorado, as part of the US Department of Energy's (DOE's) and NREL's Exemplary Buildings Program. These buildings use much less energy than equivalent code-compliant buildings and have remained within government-mandated budget constraints. Performance predictions generated as an integral part of the design process, as well as actual measured energy and daylighting performance are presented. Also presented are lessons learned during the design, construction, and initial occupancy of the buildings. Two general practices were tantamount--close communication between all team members from predesign through commissioning and occupancy, and a commitment to use of solar technologies and energy efficiency by all building design team members. It was found that, even when a team is committed to a low-energy goal, the actual energy savings can disappoint if there is lack of communication among team members. Several more specific practices were also key--a whole-building energy design approach using computerized energy simulation tools during the entire design process, and frequent inspections during construction. Additionally, the building team, usually consisting of an architect, engineer, builder, and owner, should also include an energy consultant. Furthermore, the energy design process must begin in predesign as soon as location, size, and building type are known in order to determine the main energy issues. The team should continually work together to minimize the building's energy use.
