Field Test of Aerosol-Spray and Best-Practice Duct-Sealing Approaches

摘要

A field test of an aerosol-spray duct-sealing technology and a conventional, best-practice approach was performed in 80 homes and five states to determine the efficacy and programmatic needs of the duct-sealing technologies as applied in the U.S. Department of Energy Weatherization Assistance Program. The study found that, compared with the best-practice approach, the aerosol-spray technology is 16-60% more effective at sealing duct leaks and can potentially reduce total labor time and repair costs for duct sealing by 30%. A pilot test of full-production weatherization programs using the aerosol-spray technology is recommended to develop approaches for integrating this technology with other energy conservation measures and minimizing impacts on weatherization agency logistics. Application testing of the aerosol-spray technology in mobile homes is also recommended.
