Standard designs for large commercial buildings rely on separate gas-fired hydronic heating and chilled water loops. This technology has slowly been refined with incremental energy efficiency improvements over several decades. The HVAC industry has not yet had enough time to establish how to serve...
Water heating energy use in multifamily buildings can account for 27 to 32 percent of total energy use based on 2015 Residential Energy Consumption Survey by U.S. EIA. Heat Pump Water Heating (HPWH) systems use electricity to produce hot water by transferring heat energy from one source, typically...
The proposed project will develop a new, commercial cooktop, fuel substitution measure in the CA eTRM for use in the CA Instant Rebates midstream foodservice program and appropriate IOU downstream programs. The existing measure package, SWFS026, for both commercial electric and gas cooktops will be...
As California continues to take a global leadership role in building and transportation decarbonization by aggressively pursuing energy efficiency and electrification measures to meet its climate goals, including its 2022 Scoping Plan to Achieve Carbon Neutrality (updated and released in November...
The objective of this study is to examine the energy savings, benefits, and drawbacks of various types of pool heating equipment. A macro-based Excel tool will be developed to conduct an hourly energy, cost, and GHG emissions analysis of five types of pool heating equipment: traditional gas pool...
The proposed project is a field demonstration of an electric clothes dryer controller that can be added onto an existing electric dryer. Previous studies have shown that clothes dryers operate longer than needed even in automatic termination mode, wasting energy and drying time. The proposed...
This project will explore market potential and assess how Fault Managed Power Systems (FMPS) can reduce the barriers to electrification efforts by reducing the complexity and cost of electrical infrastructure upgrades across non-residential (commercial, industrial, and agricultural) customer...
Air source heat pumps for replacing gas-powered water and space heating are a keystone technology in efforts to decarbonize buildings.[1] Heat pumps have the potential to save approximately 60% of total residential heating energy consumption and reduce GHG emissions by 13.1 MMTCO2e if installed in...
Air-to-water heat pumps (AWHPS) have been gaining traction worldwide in countries where hydronic heating is the predominant HVAC option., With the United States increasing national focus on decarbonization of the building sector, the AWHPs market still trails behind other more popular HVAC options....
This proposed CalNEXT project will develop a test method to validate that control programming is consistent with the control sequences in ASHRAE Guideline 36 (G36) High-Performance Sequences of Operation for HVAC Systems. The eventual goal is for the test method to evolve into an ASHRAE standard...
