Energy management (building project)

Weak conduit sealing on the walls of every unit.

Air leakage in diagnostic "smoke test" failed around plugs.

ECM 01: High-Efficiency Condensing DHW Heaters

Replace the existing hot water tanks with high efficiency condensing hot water heaters to

provide DHW production. Beresford currently has two (2) 250 MBH natural gas fired hot water

tanks supplying and storing DHW, each with a capacity of 80 gallons. Both tanks were installed

in 2001. There is also a constant speed recirculation pump for the DHW system.

Total ECM 01 cost: $22,000

ECM 02: Programmable Thermostats for Electric Baseboards

Space heating is currently provided by perimeter electric baseboards locally controlled by wall

mounted thermostats in the suites. There is no high temperature limit on these controls an the

suites are not metered separately for electricity

Total ECM 02 cost: $8,300
