The existing commercial foodservice (CFS) measures offered in California (CA) incentive programs are the most common pieces of equipment for this industry. Many of these measures will be considered for appliance code standards in the coming years or removed from programs due to the gas incentive...

Central heat pump water heating systems (CHPWH) are crucial for the greenhouse gas, decarbonization, and energy efficiency goals of California. This technology is relevant to a large portion of the multifamily and commercial building market and the earliest adopters are beginning to install these...

Water heating accounts for 40 percent of natural gas consumption in the residential sector, representing 7 percent of the state’s total GHG emissions (E3 2019). Water heating energy use in multifamily buildings with 5 or more units accounts for 32 percent of total energy use based on a 2015...

The California Investor-Owned Utilities (CA IOUs) analyzed validated datasets of performance data for electric pumps, motors, and compressors collected as part of Measurement and Verification (M&V) of custom incentive programs for these types of equipment commissioned by the California Public...

Standard designs for large commercial buildings rely on separate gas-fired hydronic heating and chilled water loops. This technology has slowly been refined with incremental energy efficiency improvements over several decades. The HVAC industry has not yet had enough time to establish how to serve...

Water heating energy use in multifamily buildings can account for 27 to 32 percent of total energy use based on 2015 Residential Energy Consumption Survey by U.S. EIA. Heat Pump Water Heating (HPWH) systems use electricity to produce hot water by transferring heat energy from one source, typically...

As part of their Sustainability Strategy and commitment to reach net zero greenhouse gas (GHG) emissions by 2045, SDG&E launched a Virtual Power Plant (VPP) Project in 2021. The VPP was an initiative to strengthen community resilience and electric reliability in the unincorporated community of...

The Emerging Technologies Program at SDG&E chose The Energy Smiths to evaluate the electrical load and demand response capabilities of two (2) types of Atmospheric Water Generators, also known as dehumidification drinking water systems. These systems both generate drinking water by...

The proposed project will develop a new, commercial cooktop, fuel substitution measure in the CA eTRM for use in the CA Instant Rebates midstream foodservice program and appropriate IOU downstream programs. The existing measure package, SWFS026, for both commercial electric and gas cooktops will be...

As California continues to take a global leadership role in building and transportation decarbonization by aggressively pursuing energy efficiency and electrification measures to meet its climate goals, including its 2022 Scoping Plan to Achieve Carbon Neutrality (updated and released in November...
