NREL Commerical Case Studies of Low-Energy buildings

NREL studied six commercial buildings in detail over a four-year period to understand the issues related to the design, construction, operation, and evaluation of the current generation of low-energy commercial buildings. These buildings and the lessons learned from them helped inform a set of best practices—beneficial design elements, technologies, and techniques that should be encouraged in future buildings, as well as pitfalls to be avoided. The lessons learned from these six buildings are also used to guide future research on commercial buildings to meet DOE's goals for the development of highly energy-efficient buildings. For more information, read "Lessons Learned from Case Studies of Six High-Performance Buildings." Detailed research reports are available on the High Performance Buildings Database for the case study project buildings.
