This field study is evaluating the potential of variable capacity heat pump (VCHP) systems that have the ability to use smart integrated controls, variable-speed drives, refrigerant piping, and heat recovery to provide interior temperature control on products that can be controlled by a smart...

Evaluate issues around providing energy efficiency and demand response opportunities to strip malls in California. Project involves investor owned utilities and determining how to bundle end use measures together when commercial retail operator leases space from a...

The purpose of this project is to demonstrate zero-net-energy (ZNE) or near ZNE by retrofitting several homes by applying energy efficiency measures, demand response enabling technologies, and renewable generation source. This is a field demonstration project consisting of simulation, identifying...

Variable refrigerant flow (VRF) HVAC systems are a direct expansion (DX) heat-pump technology platform built on the standard reverse vapor compression cycle. These systems are thermodynamically similar to unitary and other common DX systems, and share many of the same components—compressor,...

This field study is evaluating the potential and current DR capabilities of climate-appropriate air-conditioning (AC) systems, such as evaporative cooling and variable capacity heat pump systems. Targeted DR and EE programs can help reduce high peak demand caused by increased AC use and address...

This sub-project will evaluate the demand response capability of residential variable capacity heat pump (VCHP) systems. These are "traditional American-style" high static ducked systems. Testing will focus on one to two systems from three to five manufacturers. Lab testing and field testing will...

This sub-project will explore and document advances in product development for advanced refrigerants in refrigeration systems with the goal of identifying products for laboratory evaluation and field deployment. Advanced product development engineering, primarily built on the foundations of...

Laboratory refrigeration has not been extensively studied, with the exception of ULT freezers.  The largest insight into the energy savings potential comes from the ENERGY STAR Product Specification for Laboratory Grade Refrigerators and Freezers, published in 2016.  Data from 14...

Technology Evaporatively pre-cools condenser air, coupled with outside air pre-cooling. Field Test to determine electrical energy savings, water usage, construct ability, and maintenance issues associated with...

Field evaluation of 5 hotel/motel sites retrofitting existing commercial pool pump with variable speed controls. This effort will be used in conjunction with the market characterization in phase 1 to develop a work paper to deem this measure. The measure is currently offered in programs as a custom...
