As part of their Sustainability Strategy and commitment to reach net zero greenhouse gas (GHG) emissions by 2045, SDG&E launched a Virtual Power Plant (VPP) Project in 2021. The VPP was an initiative to strengthen community resilience and electric reliability in the unincorporated community of...

There are several studies describing indoor air quality (IAQ) and tested air-leakage rates in multifamily buildings and the dwelling unit compartmentalization rates, but much of the work is in states located in colder climates and not directly transferable to California. Therefore, there is a...

The SCE’s Technology Test Centers (TTC) evaluate a variety of technologies in controlled environments that mirror real-world conditions and customer experiences. This generates comprehensive performance data and innovative test methods which are used by SCE customers, policymakers, and utility...

The emerging technology assessed in this study is a packaged RTU that integrates a heat pump with an indirect-direct evaporative cooling (IDEC) system that is designed as a direct replacement for a traditional RTU. This project evaluates a Hybrid system in a field study and compares its...

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...
