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 research was performed to support the development and implementation of California’s Title 24, Part 6, Building Energy Efficiency Standards (“Title 24”), to better understand the potential energy and cost advantages of dedicated outdoor air systems (DOAS) and variable refrigerant flow systems...

Compare this hybrid exhaust fan airflow and power consumption to other products in the exhaust fan category. A test apparatus will be built to test powered exhaust fans delivering required airflow and static. The fan will also be installed in the field to determine a "real world" performance and...

The Palm Springs 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 Palm Springs site was renovated in 2021 with a fully decoupled HVAC system...

This project seeks to evaluate a DIY heat pump system with a typical window AC unit. The goal is to determine for a given cooling load if this technology can provide higher efficiencies with comparable installation costs to window AC...

This study was a continuation of the Central Valley Research Homes (CVRH) project. The CVRH project converted four existing single family buildings in Stockton, California into unoccupied laboratory houses to study residential energy saving opportunities. Variable capacity heat pump (VCHP) systems...

The proposed Demand Flow project includes both hardware and software components. The intent of the project is to increase plant efficiency by automatically resetting plant flow and temperature...

This project will evaluate and demonstrate new potential for otherwise unrealized demand response capability from new-to-market variable capacity commercial HVAC systems in Southern California. Southern California Edison (SCE) and their customers will benefit from this effort by unlocking a new...

In small to medium sized offices, spaces are commonly conditioned by a single-zone HVAC unit with one thermostat in the control zone. However, a zone can consist of multiple spaces, making it difficult to meet the individual comfort needs of each space. Therefore, single-zone units in commercial...

A compact, Bluetooth enabled, inline digital natural gas flow meter has entered the market, with two models anticipated for 2018 market entry (Table 1.)  Both models can be installed in tight spaces and do not require venting.  The submeters are represented as being pressure independent...
