The purpose of this project was to evaluate the performance of:Centrally ducted variable capacity heat pump (VCHP) systems.Packaged through the wall VCHP systems.Near zero global warming potential (GWP) heating and cooling technologies, including an advanced indirect/direct evaporative cooling...

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,...

Domestic hot water system electrification is a high-potential decarbonization opportunity in multifamily buildings. Based on U.S. government data, this end use accounts for 28% of multifamily residential energy consumption in the United States (EIA, 2016). Centralized heat pump water heating...

This Final Project Report summarizes the findings of PG&E’s Code Readiness Subprogram DOAS Field Research project, which collected dedicated outdoor air systems (DOAS) and variable refrigerant flow (VRF) system data from eight field sites. DOAS ventilation, which separates outdoor...

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...

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...

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...
