Radiant Heating and Domestic Hot Water Boilers – 30 Fraternity Houses at Washington & Lee Univ., VA

Working with prime contractor EnerActive Solutions, we trained the university’s HVAC technicians to install our retrofit kits on 30 radiant heating system boilers (hot water) and 10 domestic water heaters.  To measure the savings, we conducted minute-by-minute datalogging of energy consumption, indoor air and water temperatures at two of the retrofitted buildings.  An IPMVP-compliant measurement and verification analysis of the energy savings indicated 17% and 23% natural gas savings at the two buildings with indoor space and water temperatures maintained.
