Window upgrades in existing buildings offer a significant opportunity to improve building envelope thermal performance, reduce heating, ventilation, and air conditioning (HVAC) loads, and enable downsizing of HVAC systems in need of replacement. Although windows on average comprise approximately 15% of a building’s exterior surface, they are responsible for HVAC losses of about 40%. That equates to roughly 12% of a typical building’s overall energy use.
Residential heat pump water heaters (HPWHs) are two to three times more efficient than conventional gas and electric resistance water heating options. While HPWHs have been available as energy-efficient alternatives that cut greenhouse gas (GHG) emissions – and improve local air quality – for the past 15 years, they represent
Restaurants are highly energy-intensive, using five to seven times more energy than other commercial buildings, with water heating alone accounting for up to 20% of that demand. In California, the foodservice industry predominantly relies on gas for heating water, with 75% of establishments using it as their primary fuel source.
CalMTA’s exploration of the Room Heat Pumps (RHPs) Market Transformation Initiative (MTI) identified the need for research into how consumers install, interact with, and utilize this technology. We developed the RHPs Self-Installation Practices Program Strategy Pilot to yield greater insight into two primary assumed benefits of the technology, which are
CalMTA, a program of the California Public Utilities Commission and administered by Resource Innovations, will deliver high-impact solutions that further the State’s clean energy economy and climate goals to benefit all Californians. Market transformation is the strategic process of intervening in a market to create lasting change by removing market
With more than a 70% market share, gas ranges are the most prevalent cooking method in California single-family and multifamily homes. Gas stoves have been promoted for years, despite their inefficiency and the increased awareness of gas cooking’s negative impact on a home’s indoor air quality. Induction cooking devices offer
Nationwide, rooftop units (RTUs) make up approximately 37% of commercial buildings’ heating, ventilation, and air conditioning (HVAC) systems, and 50% of all commercial buildings’ floorspace.1 According to the Northwest Energy Efficiency Alliance, commercialized efficient rooftop units (ERTUs) can achieve 10-40% energy savings compared to standard RTUs. Nevertheless, product availability and
The California Market Transformation Administrator (CalMTA) develops and manages market transformation initiatives in the state to reduce energy use and reduce greenhouse gas (GHG) emissions.
CalMTA follows a rigorous process for reviewing, scoring, and then developing relevant, timely market transformation initiatives. The process supports market transformation initiative creation from concept to program development to market deployment, as well as the eventual exiting of the market.
