Based on results from a previous modeling study on Dual Fuel Single-Family Heating (ET23SWG0005) where the cost to run an electric heat pump was 68% - 144% more than a gas furnace, the GET team believes that installation of gas absorption heat pump (GAHP) water heaters will save utility costs when...

This document is a report on the Southern California Edison (SCE) Codes and Standards (C&S) Planning and Coordination (P&C) subprogram key initiatives for 2023.  The P&C subprogram aims to support California's energy transition and decarbonization goals by coordinating and...

This project will assess pathways, technical solutions and guidance for simplified DIY homeowner or general contractor replacement of existing electric and gas water heaters with new heat pump water heaters (HPWH) in California. Permitting and code requirements for water heater installations can...

The initiative is centered on exploring and implementing innovative DR methodologies, such as the Whole Home concept, to significantly enhance both customer benefits and grid performance. This strategic program aims to integrate emerging technologies that have DR capabilities, including electric...

The two largest decarbonization targets in a commercial building are typically space heating and domestic hot water. Just these two end-uses account for well over 90% of the natural gas usage in most commercial buildings (excluding food service). Energy efficient, cost-effective solutions for...

In commercial buildings where forced-air heating and cooling systems are employed, the efficiency of ductwork plays a pivotal role in both energy management and indoor air quality.  According to the U.S. Energy Information Administration's (EIA), ventilation systems in commercial buildings consume...

The proposed project is a field demonstration of natural refrigerant (CO2) for high volume milk cooling on the dairy farm. Traditional methods of cooling high flow rates of milk have evolved over time from the use of different synthetics such as CFC’s, HCFC’s, and HFC’s. This proposed CO2 chiller...

With increased residential electrification, households are reducing their carbon footprint by replacing gas appliances and vehicles with all-electric alternatives. In California, the state has set a goal to reach 100 percent zero-carbon energy by 2045 (Executive Order B-55-18). While the reduction...

The existing SWWP004-03 Water Pump Upgrade Measure Package has been approved through 12/31/2024, but the California Public Utilities commission (CPUC) has mandated that this Measure Package (MP) cannot continue beyond 2024 without a Market-Based Industry Standard Practice (ISP) Study compliant with...

High humidity poses a significant challenge in modern fully enclosed greenhouses and state-of-the-art vertical farming setups, fostering the growth of fungal diseases such as botrytis and impeding the plant transpiration process causing adverse impacts on plant health and growth. One study...
