Do-It-Yourself Solar Heating. Final Report

摘要

Presented is a do-it-yourself method of building a solar greenhouse for the purpose of heating a house. During the operational periods, following the construction of the greenhouse, severe problems were encountered. The heat losses at night during the heating season lowered temperatures inside the greenhouse to below freezing on some occasions. Overheating was a problem encountered during the summer months. Daily high and low temperatures are recorded for both inside and outside of the greenhouse. The payback period for the present greenhouse was calculated to be approximately 21.5 years. Recommendations for improving the greenhouse design and efficiency are included. (ERA citation 10:041532)
