摘 要：This report summarizes commissioning, short-term testing, utility bill data analysis, and results of on-site monitoring with a focus on the three-bedroom base scope and DER units. Findings from the implementation, commissioning, and short-term testing include air infiltration reductions of greater than 60% in the DER building; a hybrid heat pump system with a savings to investment ratio > 1 (relative to a high efficiency furnace) which also provides the resident with added incentive for energy savings; and duct leakage reductions of > 60% using an aerosolized duct sealing approach.
