Solar Heating Feasibility Study.

Abstract : A growing number of buildings are equipped to capture solar energy for space and water heating. Calculations for a local Navy two-story apartment building using available weather and insolation data indicate that during a typical year a solar collector with an area of 1000 square feet, 1/3 the plan area of the building, could supply 173 million Btu, 37% of the heat required, at an annual cost of $9 per million Btu. This could be reduced to $5 per million Btu if the first cost of the collector were reduced from the estimated $8 to $3 per square foot. (Author)
