A new study by Newport Partners LLC entitled Whole House Analysis Of Energy Efficiency Upgrades For Existing Homes, commissioned by the Propane Education & Research Council (PERC) in the US, offers insight into how construction professionals can help homeowners prioritise energy saving retrofits.
As residential buildings consume approximately 20 per cent of energy usage in the US, the study examined dozens of energy efficiency upgrades, such as appliances, building improvements, space conditioning systems, renewable energy and domestic water heating systems, in 10 locations across five climate zones within the USA. The study looked at payback times and annual cost savings.
Tracy Burleson, director of residential programs for PERC, said: “Homeowners rely on construction professionals to know which upgrades are the most cost effective for improving a home’s energy efficiency. This new study serves as a guide to answering commonly asked questions about prioritising energy upgrades. Construction professionals can also use the study to help their customers proactively replace targeted mechanical systems that are near the end of their life with high efficiency equipment that will yield good returns on investment.”
