Measured Results of Energy Conservation Retrofits in Residential Buildings
This study summarizes measured data on energy savings from conservation retrofits in existing residential buildings to the building shell, principally insulation of exterior surfaces, window treatments, and infiltration-reduction measures, are the most popular, although data on various heating system retrofits are now available. The average retrofit investment per unit in multifamily buildings is approximately $700, far lower than the average of $1350 spent in single-family residences. Savings achieved are typically 20% to 30% of pre-retrofit space heating energy use, although large variations are observed both in energy savings and in costs per unit of energy saved. Particularly cost-effective retrofit strategies are identified based on measured energy use data. Predicted versus actual savings are also compared for groups of homes in 24 retrofit projects.
