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...

Air-to-water heat pumps (AWHPS) have been gaining traction worldwide in countries where hydronic heating is the predominant HVAC option., With the United States increasing national focus on decarbonization of the building sector, the AWHPs market still trails behind other more popular HVAC options....

This proposed CalNEXT project will develop a test method to validate that control programming is consistent with the control sequences in ASHRAE Guideline 36 (G36) High-Performance Sequences of Operation for HVAC Systems. The eventual goal is for the test method to evolve into an ASHRAE standard...

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...

Laboratory cold storage solutions such as freezers, refrigerators, and cryogenic storage tanks are critical to keeping valuable reagents and priceless samples safe. Ultra-Low Temperature Freezers (ULTs) are designed for laboratory applications that maintain set point storage temperatures between...

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...

This market characterization study builds on the efforts and findings of the 2022/2023 CalNEXT Residential Housing Characteristics Study ET22SWE0022. The ET22SWE0022 study's objectives were to: • Characterize existing DAC single family residence (SFR) building stock through publicly available...

VEIC proposes a market study of energy efficiency for medical devices. The market study will quantify the potential for energy savings, identify device types with opportunity for higher efficiency, define the mechanisms for achieving higher efficiency, and recommend efforts for achieving higher...

The proposed project will continue the measure package development process for residential high-efficiency windows, picking up where project ET23SWE0043 ends. The proposed project will provide measure package development support from the point of Cal TF submission of the measure package to CPUC...
