Central heat pump water heater (CHPWH) systems are playing a pivotal role in the decarbonization of multifamily and commercial buildings. These systems can provide electrified, efficient hot water for both new and existing buildings while minimizing grid impact and energy costs with load shifting...
This project will assess the market opportunity and technology performance of new split heat pump water heater (HPWH) designs for direct replacement of inefficient gas (including natural gas and propane) and electric water heaters located in constrained spaces in California multifamily buildings....
This project involves a market study for the agricultural sector adoption of PEI-rated pumps in California. California agriculture irrigates more than 9 million acres using roughly 34 million acre-feet (MAF) of water typically diverted from surface waters or pumped from groundwater and consumes 8.8...
CHPWH systems in multifamily and commercial buildings serve two purposes: heating city water entering the building to usable hot water temperatures for occupants and maintaining the water temperature in the distribution and recirculation system. Temperature maintenance typically makes up about 30%...
HVAC Contractors working on energy efficiency and building electrification projects face technical and regulatory challenges. To support them, various organizations—including for-profits, non-profits, manufacturers, and state agencies—have developed software-based tools. These tools assist with...
This project strives to collect comprehensive laboratory test data on the heating, cooling, dehumidification, and native controls performance of Micro Heat Pumps (MHP), that are of interest to California’s consumers. This effort will build on the data collected under CalNEXT Project ET23SWE0034 -...
This project demonstrates the energy-saving benefits of phase change material (PCM) in drop ceilings to reduce cooling energy in California schools, where HVAC systems account for 50% of energy use (Energy Information Administration, 2018). Cooling dominates HVAC loads in warm classrooms due to...
More than 80% of the buildings that will exist in 2050 are already built and are existing buildings. Created for new construction projects, American Society of Heating, Refrigeration, and Air-Conditioning Engineers (ASHRAE) Guideline 36 (G36), “High-Performance Sequences of Operation for HVAC...
California’s decarbonization goals are dependent on individual decision makers choosing to upgrade systems dependent on fossil fuels. Reaching those decision makers is challenging, none more so than commercial kitchen owners and operators, who are managing a variety of factors including small...
