The TECH Working Data Sets provide anonymous data gathered from incentive applications submitted by TECH participating contractors. Each row represents a unique installation of either a Heat Pump Water Heater ("HPWH") or a Heat Pump Heating, Ventilation, and Air-Conditioning ("HP HVAC") system. All data is anonymous and cannot be used to reidentify the homes in which installations occurred.

Data fields (columns) describing each installation include:

• Information about the site, such as the California Climate Zone and CalEnviroScreen Disadvantaged Community status
• Data on the installed equipment and replaced equipment
• Total Project Cost (including equipment and installation costs)
• Incentive provided by TECH Clean CA and any layered partner programs
• Installation details describing the HPWH/HP HVAC installation, such as duration and quality installation measures performed by the installer.

There are three TECH Working Data Sets.

1. The TECH Working Data Set_Single-Family contains data on individual heat pump installations performed by contractors who typically service single-family homes and applied for an incentive through the TECH Clean California Single Family incentive program. This dataset includes a small number of installations performed in small Multifamily homes as well.
2. The TECH Working Data Set_Multifamily contains data on large-scale heat pump installations in multifamily residential buildings, typically involving large central systems that serve multiple apartments and/or many small unitary systems installed in adjacent apartments. Contractors applied for these incentives through the TECH Multifamily Incentive Program.
3. The TECH Working Data Set_Low Income Direct Install contains data on direct install electrification projects in low income homes in partnership with programs like Energy Savings Assistance (ESA). Read more here.

Primary Data Set Sources:

• Incentive applications completed by TECH participating contractors
• Qualified Product Lists maintained by the Air-Conditioning, Heating, and Refrigeration Institute (AHRI), Northwest Energy Efficiency Alliance (NEEA), and United States Department of Energy (US DOE)
• California Climate Investments Priority Populations 2023 Disadvantaged Communities and low-income community areas
• Partner programs offering incentives that layer with TECH incentives (see the About TECH Clean CA webpage)
• The California Electronic Technical Reference Manual (“eTRM”), used to estimate ex ante annual electricity and gas savings for each project. As many projects as possible are assigned a Measure Package ID and Measure Offering ID, as well as deemed a savings estimate from the following Measure Packages: SWWH014, SWWH025, SWWH028, SWHC044, SWHC045, SWHC050. All claims that cannot be assigned a Measure Offering ID are assigned a generic savings estimate based on Measure Package data.
