Buildings can be designed in harmony with the natural environment, and new techniques of "active" solar design exist to collect and use solar energy for space heating and cooling. Preservation and reuse of existing buildings and neighborhoods are other ways to conserve energy. (Author/MLF)

This energy conservation workbook series was developed to provide specific data on the effect of various design and operating decisions on both cost and energy consumption. It is designed to make clear the energy consumption and cost implications of various building design and operating decisions in terms that both the layman and design…
