Project SAGE: solar assisted gas energy. Final report and executive summary
The Phase III basic objective was establishment of a technical and economic baseline for proper assessment of the practical potential of solar water heating for apartments. Plans can then be formulated to improve SAGE technical design and performance; reduce SAGE costs; refine SAGE market assessment; and identify policies to encourage the use of SAGE. Two SAGE water heating systems were installed and tested. One system was retrofit onto an existing apartment building; the other was installed in a new apartment building. Each installation required approximately 1000 square feet of collector area tilted to an angle of 37/sup 0/ from the horizontal, and each was designed to supply about 70 percent of the energy for heating water for approximately 32 to 40 units of a typical two-story apartment complex in Southern California. Actual contruction costs were carefully compiled, and both installations were equipped with performance monitoring equipment. In addition, the operating and maintenance requirements of each installation was evaluated by gas company maintenance engineers. Upon completion of the installation analysis, the SAGE installation cost was further refined by obtaining firm SAGE construction bids from two plumbing contractors in Southern California. Market penetration was assessed by developing a computer simulation program using the technical and economic analysis from the installation experience. Also, the project examined the public policies required to encourage SAGE and other solar energy options. Results are presented and discussed. (WHK)
