Market Characterization of the indoor agriculture market, future outlook, and savings potential. To address challenges of climate variability, population growth, and land use, there have been efforts to grow more products in urban areas. Indoor farming is becoming more common but come with various...

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...

Evaporative coolers provide cooling without refrigerants and operate most efficiently in low-humidity conditions. To evaluate the feasibility of installing an indirect/direct evaporative cooler in lieu of a traditional split-system, refrigerant-based, central air conditioning system, the SDG&E...

SDG&E expects significant load growth in the indoor agriculture sector, primarily driven by the legalization of recreational cannabis use as well as increased interest and growth in indoor agriculture development opportunities at large. In line with efforts to encourage producers and trade...

Demand management and flexibility test of a commercial building with implemented EE and DR...

In 2016, Vista Grande Elementary School applied for Prop 39 funding for a Zero Net Energy (ZNE) retrofit. SDG&E’s Emerging Technologies (ET) program supported this effort by providing energy modeling, energy efficiency recommendations, a Measurement & Verification (M&V) plan, and...

Advanced Lighting Control Systems (ALCS) Bench Testing – Plug Load Controls aims to revisit and refine the technology validation program developed in Phase I. ALCS Bench Testing - Plug Load Controls focuses on the plug load specific additions that are available with select ALCS and evaluates...

The Study’s goal was to investigate whether Title 24 energy code compliance requirements and energy simulation rulesets for RTU/economizer systems adequately reflected real world performance in California climate zones and make recommendations based on the investigation findings. The Study...

PG&E’s Demand Response Emerging Technology (DRET) group initiated a Battery Study to investigate the ability to utilize residential photovoltaic solar systems paired with a Tesla Powerwall home battery systems to support state electric grid reliability in times of high electricity demand...

This project will help determine the effectiveness of Phase Change Materials (PCMs) in cold storage applications at Low Temperature -10 - 0 F (-23 - 18 C). Controls will also be implemented into the study to determine how compatible it is with PCMs. A total of 4 tests will be done on warehouses to...
