A solar heating system combined with increased thermal insulation at Parker Junior High School has resulted in a savings of about 75 percent in energy use. (Author/MLF)

A project testing solar heating and cooling in an existing building, the George A. Towns Elementary School, is intended to provide information on system design and performance, allow the identification and correction of problems encountered in installing large units, and gauge community/user reaction to solar equipment.

The proposed Niskey Lake Middle School is designed to have solar heating in half of the building, solar water heating for the entire facility, and solar cooling for the administration area. (Author/MLF)

The soon-to-be-completed North Campus of the Community College of Denver demonstrates a conviction on the part of the state and the design team that the use of solar energy is economically and technologically and alternative to the continued consumption of fossil fuel. (Author/MLF)

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)
