Summary

A high-velocity small-diameter duct system was tested in a new, unoccupied, single-family home in Pittsburgh, Pennsylvania, as part of the U.S. Department of Energy's Building America program. The 2,772 ft2 home, completed in 2010, features a whole-house energy recovery ventilator, reflective shingle roof, R-60 blown ceiling insulation, and triple-pane low-e windows. The system's performance was assessed, and results showed that it did not meet ASHRAE criteria during heating defrost cycles and ACCA criteria for room-to-thermostat temperature uniformity in some rooms due to insufficient airflow and lack of response to solar gains. Lessons learned include lower material and installation costs, but also critical register placement and reduced fan efficacy at high airflow rates. The home achieved a Home Energy Rating System Index of 27, with projected annual energy cost savings of $559, and an incremental cost of energy-efficiency measures of $15,000.
