Heat pump space conditioning and water heating can greatly reduce energy consumption compared to existing electric resistance or natural gas combustion options. Requirements for electrical service upgrades add cost and installation delays for customers considering retrofitting heat pumps for space...

This project is a demonstration and comparison study between conventional Normalized Metered Energy Consumption (NMEC) analysis and a Measurement & Verification (M&V) method which enhances NMEC with rapid & repeatable interventions. The Enhanced NMEC (E-NMEC) with Rapid Interventions (RI) is...

In January 2022 we completed a laboratory study (ET19SCE1110) on the proposed air vane technology under contract with the SCE ET&P group to investigate the benefits of installing air vanes on vertical open refrigerated display cases used in grocery stores.  In the lab assessment, a reduction of 17...

This Gas Emerging Technology (GET) project includes research into site screening criteria and sizing methods for gas absorption heat pump water heaters (GAHPs). GAHPs have been around for many years, but the application of this technology to domestic hot water (DHW) systems is novel and presents...

ERI is proposing to perform a market and technology study that will begin with a market assessment of Vortex Water Treatment (VWT) technology and applications in use in California. The resulting study will analyze current technologies utilized during ice resurfacing in ice arenas and the energy...

This Gas Emerging Technology (GET) study project is proposed to monitor and analyze the potential gas energy savings from adding a chemical additive to hydronic heating systems in commercial or multifamily buildings in California. These water additives claim to reduce the surface tension of the...

In recent years networking equipment manufacturers have expanded from their core product lines and have developed and promoted mesh networking systems (MNS) for residential consumers. Currently, 40% of manufacturers’ advertised Integrated access device (IAD) products are MNS. Unlike the previous...

This project aims to develop a measure package for residential windows. With the recent California Decision 23-04-035 that outlines a path for eliminating gas incentives, windows are considered a “gas exempt” measure due to providing gas savings without incentivizing a gas appliance. The California...

VEIC will investigate the potential market opportunity and decarbonization impact of installing propane-based air-to-water heat pumps (AWHPs) in residential and commercial buildings across California. Traditional heat pumps use hydrofluorocarbon (HFC) and/or hydrofluroolefin (HFO) synthetic...

VEIC proposes to demonstrate a building simulation modeling tool that links backwards looking data intelligence with forward projecting Open Studio model simulations. The tool would use Advanced Metering Infrastructure (AMI) data and regression methods to identify customer specifics about when and...
