As part of their Sustainability Strategy and commitment to reach net zero greenhouse gas (GHG) emissions by 2045, SDG&E launched a Virtual Power Plant (VPP) Project in 2021. The VPP was an initiative to strengthen community resilience and electric reliability in the unincorporated community of...

The Emerging Technologies Program at SDG&E chose The Energy Smiths to evaluate the electrical load and demand response capabilities of two (2) types of Atmospheric Water Generators, also known as dehumidification drinking water systems. These systems both generate drinking water by...

The successful implementation of solar photovoltaic in California has resulted in a monumental shift of our daily grid net demand profile. So much so, that net demand dips well below historic usage profiles and has shifted our peak demand period from the middle of the day to the evening hours (4:00...

Domestic hot water system electrification is a high-potential decarbonization opportunity in multifamily buildings. Based on U.S. government data, this end use accounts for 28% of multifamily residential energy consumption in the United States (EIA, 2016). Centralized heat pump water heating...

This research project was performed to support the development and implementation of California’s Title 24, Part 6 Building Energy Efficiency Standards (Title 24) by better understanding the impact of installation location and ventilation on consumer integrated heat pump water heaters (HPWH)...

This research was performed to support the development and implementation of California’s Title 24, Part 6, Building Energy Efficiency Standards (“Title 24”), to better understand the potential energy and cost advantages of dedicated outdoor air systems (DOAS) and variable refrigerant flow systems...

This research was performed to help those involved with the development and implementation of California’s Title 24, Part 6, Building Energy Efficiency Standards (“Title 24”), better understand the real-world performance of Networked Lighting Controls (NLCs) and their advanced capabilities. NLCs...

The industry is at the very beginning of the process to electrify existing large commercial buildings. Technological and financial elements of electrification retrofits remain unknown, particularly for this market segment. However, there are many recent innovations that designers are pursuing to...

Demand Response Control on Integrated Space Conditioning System Field Test Results of Integrated Variable Refrigerant Flow and Indirect Evaporative Cooling System As an activity adjunct to the California Energy Commission (CEC) project “Climate Appropriate Innovations for Variable Refrigerant...

This project aims to develop a measure package for residential windows. With the recent California Decision 23-04-035 that outlines a path for eliminating gas incentives, windows are considered a “gas exempt” measure due to providing gas savings without incentivizing a gas appliance. The California...
