CalMTA’s Phase II research for the Induction Cooking market transformation initiative (MTI) identified key barriers to adoption, including low consumer awareness of induction technology and its benefits, cultural and consumer attachment to gas cooking, and concerns about the durability of newer induction products. To address these challenges, CalMTA sought to test interventions
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
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
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.
