Nevada: Vegas Retrofits through Building America Enhance Home Performance
|Positive Impact:||This project demonstrates that home efficiency retrofits, particularly for foreclosed homes offers a new model for communities across the country to save money and create new job and business opportunities. It also demonstrates that cost effective energy-efficiency upgrades can be successfully implemented in a hot, dry Southwest climate.|
|Locations:||Las Vegas, Nevada|
|Partners:||City of Las Vegas|
|EERE Investment:||Technical assistance|
|Clean Energy Sector:||Energy-saving homes, buildings, and manufacturing|
The EERE report Retrofitting Vegas: Implementing Energy Efficiency in Two Las Vegas Test Homes notes that during the housing crisis, more than 11% of the existing housing stock in Las Vegas is in foreclosure (more than 8,100 homes). There is strong potential for achieving significant energy savings through retrofit activities in this region. If 10% of those homes implement the two solution packages recommended by two Building America research teams involved in this effort—the Consortium for Advanced Residential Buildings (CARB) and Building America Retrofit Alliance (BARA)—5% at the 50% energy savings target and 5% at the 30% energy savings target, collectively, residents would experience an energy reduction of more than 71,000 MMBtu, or roughly $655,000 in annual utility bill costs. Additionally, the labor and materials needed for these retrofits will help support new job and business opportunities.
2011 and 2013, BARA and CARB worked with the City of Las Vegas to retrofit two
foreclosed homes acquired through the U.S. Department of Housing and Urban
Development’s Neighborhood Stabilization Program. The retrofits focused on air
sealing the building envelope; replacing windows with double-pane, low-e
retrofit windows to reduce solar heat gain; and installing a high-performance
heating, ventilation, and air conditioning system. The upgrades increased the Carmen
home’s efficiency by 51% and the Sierra Hill home’s efficiency by 34The
upgrades are predicted to reduce the annual utility bill for the Carmen home by
approximately $1,140 (45%) and $480 (29%) for the Sierra Hills home. The
program is currently using the energy modeling information to upgrade 12 more
homes in Las Vegas, as well as several home retrofits in Henderson, Nevada. The
two Las Vegas homes were also used to provide educational experiences to home
performance professionals, building trades, remodelers, and the public. Local
contractors were trained on air-sealing, insulating, and upgrading heating,
ventilation, and air conditioning units.
The Buildings Technologies Office (BTO) leads a vast network of research and industry partners to continually develop innovative, cost-effective energy saving solutions—better products, better new homes, better ways to improve older homes, and better buildings in which we work, shop, and lead our everyday lives.
