This study aims to characterize the performance of a second Gas Absorption Heat Pump (GAHP) unit to sufficiently populate model inputs in EnergyPlus. Gas Technology Institute (GTI) Energy will serve as a contractor for this study. They will develop a test plan including instrumentation, plumbing,...

The Study provided a standards-based approach (OpenADR 2.0b) for Providers to receive accurate pricing for their residential customers. ParticipatingProviders were expected to utilize this pricing data to accomplish price-optimized load shifting to provide different services such as customer bill...

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 project team proposes to conduct a field demonstration project that will seek to install intelligent power management technologies (IPMTs) (e.g., smart electrical panels, smart circuit breakers/relays) in manufactured housing with limitations in both customer-side and utility-side electric...

Transcritical carbon dioxide (TC CO2) is emerging as the preferred low Global Warming Potential (GWP) option for commercial refrigeration systems in supermarkets and grocery stores. The unique system architecture and operating characteristics of CO2 make it difficult to model because these systems...

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...
