California eTRM (Electronic Technical Reference Manual) already offers a statewide deemed measure for clean water pumps, providing energy savings values and a path for payment of rebates for pump replacement and improving their efficiency. However, wastewater pumps do not currently have a...

The proposed project is a demonstration of an emerging high efficiency heat pump product for multifamily space conditioning applications. This project will demonstrate the application of Double Ducted Packaged Terminal Heat Pumps (DDPTHP) in a low-income multifamily new construction project in 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)...

Many existing non-residential rooftop package units (RTU) including heat pumps do not have monitoring capabilities where temperature, pressure, and energy are known in real time. This is the typical case found in commercial primary and secondary schools within public school districts. The target...

PG&E’s Demand Response Emerging Technology (DRET) Program initiated a residential Battery Study to investigate the potential to utilize residential photovoltaic solar systems paired with a home battery system to support state electric grid reliability. PG&E designed the study to learn...

This project involves a market characterization study for Industrial Heat Pumps. Industrial Heat pumps are heat pumps that are used in large-scale industrial processes. Standard heat pumps are generally used for residential and small-scale commercial applications. Industrial heat pumps, on the...

This project will analyze the current CA eTRM measure packages for residential Heat Pump Water Heaters (HPWH) based on market and product data to identify gaps and recommend enhancements to the measure offerings. The final report will be delivered to the California Technical Forum and other eTRM...

The State of California has an ambitious goal to install at least 6 million heat pumps by 2030. To address this need, several novel “micro” heat pumps are emerging in the consumer market that offer the ability to provide space heating and are powered by common household 120V electrical service...

This project is proposed to research and analyze the market of Infrared (IR) heating technologies to provide actionable recommendations of technologies and gaps for further study by the Statewide Gas Emerging Technologies (GET) program. This project will cover IR heating systems in industrial and...

Several past studies tested air-leakage rates in multifamily buildings and dwelling unit compartmentalization rates, but most of these studies were performed in colder climate states and are not directly transferable to California. Therefore, there is a general lack of California specific...
