TECH Working Data Set


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 two 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.

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.

Greenhouse Gas Impacts Data Set - Coming Soon


The Greenhouse Gas Impacts Data Set provides anonymous meter-based gas and electricity consumption data for California residents who installed a piece of technology that received a TECH incentive.

Primary Data Set Sources:

  • Meter-based gas and electricity consumption data for residential customers of Pacific Gas & Electric (PG&E), Southern California Gas (SoCalGas), Southern California Edison (SCE), San Diego Gas & Electric (SDG&E), Southwest Gas (SWG), Sacramento Municipal Utility District (SMUD), and Los Angeles Department of Water and Power (LADWP) provided by the California Energy Commission (CEC) and California Public Utilities Commission (CPUC)
  • Meter-based data in the GHG Savings Data Set follow CPUC requirements for data aggregation and data sharing to preserve the anonymity and privacy of California residents.
