This study aims to characterize the performance of a Robur Gas Absorption Heat Pump (GAHP)-A unit to sufficiently populate model inputs in EnergyPlus. Gas Technology Institute (GTI) Energy will serve as a contractor for this study. They will develop a test plan including instrumentation, plumbing,...

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...

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...

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...

With rising housing costs in California, the prevalence of affordable manufactured housing has been growing, especially in areas affected by recent wildfires. Many homeowners find manufactured housing to be a means to get them back in a home much faster, and much more affordably. For years,...

Heat pumps provide significant energy savings and a path for electrification, but they typically use refrigerants with a high global warming potential (GWP), which can degrade the greenhouse gas reductions from energy savings. The California Air Resources Board (CARB) has regulations that will...

Heat Pump space conditioning systems (HP) are a key tool in meeting the state’s GHG goals, however, recent data from field M&V studies has shown significant energy penalty from the incorrect operation of crankcase heaters (CCH), defrost controls and standby power usage – up to 50% of the annual...
