Commercial Case Study: Jamaica Plain

This is a commercial project funded through the Massachusetts Clean Energy Council (Mass CEC) and the federal government.The System produces 50% of the domestic hot water use of the entire building, saving over 1,111 Therms per year which in the equivalent of 111,111,111 Btu's or 32,555 kilowatt-hours.

The system saves 13,650 pounds of carbon dioxide from being released into the atmosphere each year or the equivalent of 341 mature trees, which means that over the 30 year lifetime of the system will save 205 tons of CO2.

The array consists of 12 Apricus AP 30 collectors (360 evacuated tubes). Its frame consists of a galvanized racking sytem.

This project has an exterior pipe chase with one inch exterior insulation.

The solar storage tank contains the heat exchange coils and the domestic hot water piped in reverse. The drain back tanks hold all of the glycol when the system is off or satisfied.
