This chapter contains data on two market transformation programs that reach across the United States and to other countries: the ENERGY STAR program, jointly administered by the U.S. Environmental Protection Agency and the U.S. Department of Energy, and the U.S. Green Building Council's Leadership in Energy and Environmental Design (LEED) rating system. It also includes data on three professional certifications and five case studies of high performance buildings. The main points from this chapter are summarized below:
