Market Evaluation Study: Solar Heating and Domestic Hot Water Heating in DOD Buildings.
Abstract
This study assesses the potential market for combined solar space heating and domestic hot water heating in Department of Defense (DOD) buildings. The study considers eight building categories: family housing, bachelor enlisted quarters, bachelor officers' quarters, administration, training, operational, community support, and recreational, which together contain 683 million sq ft (61.5 million m2), or 40 percent of the DOD inventory. All buildings were assumed to be oil heated. The buildings were grouped by climatological/solar regions, and the loads for each building type were determined by using the Energy Utilization Index (EUI) method. Solar system performance in each region was obtained by using the U.S. Army Construction Engineering Research Laboratory universal curve method. The life-cycle costs of providing solar space heating and domestic hot water heating were analyzed, and the DOD market potential for installed solar system costs of $9, $15, and $20 per square foot were determined. The study shows that at an estimated initial fuel cost of $3.50 MBtu for oil heating, a 10 percent cost of money, and an 8.5 percent overall fuel inflation factor, solar systems for space heating and domestic hot water heating become economically feasible when installed system costs are $14/sq ft (150/sq m. When installed system costs reach $9/sq ft ($97/sq m., the market potential becomes 172 million sq ft (15.5 million sq m.) of solar collectors. The study also shows the largest potential market at these economic conditions to be family housing, which contains a total of 102 million sq ft(9.2 million sq m. (Author)
