New and Underutilized Technology: Solar Water Heating
The following information outlines key deployment considerations for solar water heating within the Federal sector. This information spans:
Solar water heating uses solar thermal collectors to heat water.
Solar water heating is applicable in most building categories.
Climate and Regional Considerations
Solar water heating is best in regions with high insolation.
Key Factors for Deployment
The Energy Independence and Security Act (EISA) of 2007 requires 30% of hot water demand in new Federal buildings and major renovations to be met with solar water heating equipment providing it is life-cycle cost effective.
Federal agencies must consider collector placement location to optimize solar water heating efficiency.
Federal energy savings, cost-effectiveness, and probability of success are ranked 0-5 with 0 representing the lowest ranking and 5 representing the highest ranking. The weighted score is ranked 0-100 with 0 representing the lowest ranking and 100 representing the highest ranking.
