The Sacramento Case Study is one of eight buildings evaluated under a Code Readiness field monitoring research effort to better understand real-world performance of dedicated outdoor air systems (DOAS) in California. The Sacramento site was renovated in 2019 with a partially decoupled HVAC system...

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...

The Pacific Gas and Electric Central Valley Research Homes (CVRH) project is the product of multiple years of effort by leading energy efficiency researchers and represents a significant investment of funding from the California Energy Commission, California Investor Owned Utilities (IOUs), and...

The Martinez Case Study is one of eight buildings evaluated under a Code Readiness field monitoring research effort to better understand real-world performance of dedicated outdoor air systems (DOAS) in California. The Martinez site was renovated in 2019 with a fully decoupled HVAC system using a...

The Santa Rosa Case Study is one of eight buildings evaluated under a Code Readiness field monitoring research effort to better understand real-world performance of dedicated outdoor air systems (DOAS) in California. The Santa Rosa site was renovated in 2019 with a new HVAC system using a DOAS unit...

A remote monitoring and control system (RMCS) was deployed in four restaurants in PG&E’s service territory. The technology was deployed to monitor each restaurant’s electric end-uses and provide smart controls to eliminate energy waste and maintain smooth operations. The...

This research was performed to help those involved with the development and implementation of California’s Title 24, Part 6, Building Energy Efficiency Standards (“Title 24”), better understand the real-world performance of dedicated outdoor air systems (DOAS) and variable refrigerant flow (VRF)...

The Pacific Gas and Electric Central Valley Research Homes (CVRH) project is the product of multiple years of effort by leading energy efficiency researchers and represents a significant investment of funding from the California Energy Commission, California Investor Owned Utilities (IOUs), and...

This Final Project Report summarizes the findings of PG&E’s Code Readiness Subprogram DOAS Field Research project, which collected dedicated outdoor air systems (DOAS) and variable refrigerant flow (VRF) system data from eight field sites. DOAS ventilation, which separates outdoor...

Optimizing HVAC demands for residential cooling systems is becoming increasingly important in California as the electric grid becomes increasingly powered by renewable energy generation. Hydronic systems in general are particularly amenable to load shifting because they can be coupled to thermal...
