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 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 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...

The proposed project is a field demonstration of an electric clothes dryer controller that can be added onto an existing electric dryer. Previous studies have shown that clothes dryers operate longer than needed even in automatic termination mode, wasting energy and drying time. The proposed...

This project will explore market potential and assess how Fault Managed Power Systems (FMPS) can reduce the barriers to electrification efforts by reducing the complexity and cost of electrical infrastructure upgrades across non-residential (commercial, industrial, and agricultural) customer...

Air source heat pumps for replacing gas-powered water and space heating are a keystone technology in efforts to decarbonize buildings.[1] Heat pumps have the potential to save approximately 60% of total residential heating energy consumption and reduce GHG emissions by 13.1 MMTCO2e if installed in...

Mechanical ventilation is becoming more prevalent due to Indoor Air quality (IAQ) concerns, particularly as construction trends move towards tighter envelopes to increase efficiency. Yet there is a tension between providing ventilation to ensure good IAQ and reducing the energy and demand impacts...

120-volt plug-in heat pump water heaters (HPWHs) are a proven, market-ready technology offering significant decarbonization potential as emergency replacements in the small medium business market. It is estimated that 90% of water heating replacements occur on an emergency basis. Without an easy,...

The proposed project will evaluate patent-pending compressor controller technology through a field demonstration. The field demonstration entails installing the technology onto an existing VRF system with inverter-driven compressor to understand its potential energy savings. Technology is...

Lawrence Berkeley National Laboratory (LBNL) submitted a proposal to the CEC in response to Electric Program Investment Charge (EPIC) solicitation GFO-19-309.  Southern California Edison (SCE) provided a Letter of Commitment in support of LBNL’s proposal for the EPIC solicitation. The proposal was...
