Heat Pump space conditioning systems are an important technology in the residential sector for both energy efficiency and decarbonization efforts. This project aims to address gaps in current EE Portfolio offerings for Residential Heat Pumps when retrofitting existing buildings with no existing...

The current measure package for Water-Cooled Chillers (WCC) has several shortcomings that have been identified, most notably an unrealistic full-load efficiency (FLE, in kW/ton) requirement to go along with the part-load efficiency (PLE, in IPLV) requirement. Current WCC measures are restrictive in...

This project will study a Thermal Energy Storage System (TESS) that utilizes phase change material (PCM) inserted in the supply duct combined with smart controller optimizing for compressor limiting operations during peak demand periods. The TESS is actively managed to get the maximum benefit by...

Meeting the state’s climate and clean air goals requires electrification of the existing residential housing stock. Residential electrification is often erroneously assumed to require electrical panel and service upgrades in dwellings that currently have less than 200A of capacity. Under this...

This project will assess the decision processes of residential customers and contractors related to emergency water heater replacement (e.g., What priorities drive customer choices? What priorities drive contractor recommendations?) and technical solutions for emergency water heater replacements...

The proposed study will evaluate emerging technologies designed to remove a majority of containments in dairy wastewater efficiently, allowing facilities to expand their reuse of wastewater in other areas such as drip irrigation, drinking water, facility maintenance, etc. The technologies help...

There are currently no deemed savings for high performance windows in commercial buildings in CA. A first step towards assessing the potential for a deemed measure for high performance commercial windows is to understand the market potential for such a measure. A statewide market study will be...

The 2022 C&S Planning and Coordination Key Initiatives Report presents the activities and achievements of the P&C subprogram in the program’s five elements: Decarbonization, Grid Harmonization, Code Harmonization, Strategic Planning and Coordination, and Program Coordination. For the...

This project will be a market assessment on California hospitals to evaluate the current natural gas end use technology present in hospitals today. This study will look at existing data on hospital equipment use, energy, and natural gas consumption, and conduct research to assess the potential for...

This Gas Emerging Technology (GET) study project is proposed to monitor and analyze the potential gas energy savings from replacing non-controlled domestic hot water (DHW) circulator pumps with smart circulator pumps. Smart circulator pumps use either a timer, aquastat, timer + aquastat, or an...
