Advanced Lighting Control Systems (ALCS) Bench Testing – Plug Load Controls aims to revisit and refine the technology validation program developed in Phase I. ALCS Bench Testing - Plug Load Controls focuses on the plug load specific additions that are available with select ALCS and evaluates...

This project will help determine the effectiveness of Phase Change Materials (PCMs) in cold storage applications at Low Temperature -10 - 0 F (-23 - 18 C). Controls will also be implemented into the study to determine how compatible it is with PCMs. A total of 4 tests will be done on warehouses to...

San Diego Gas and Electric (SDG&E) contracted with Demand Side Analytics (DSA) to conduct analysis and develop tools to target Demand Response (DR) programs, behind-the-meter (BTM) battery storage, and distributed solar. The team designed the research tool to inform customer targeting and...

SCE provided a Letter of Commitment (LOC) in support of LBNL’s proposal titled “A framework to characterize the performance of building components in providing flexible loads and building services using a hardware-in-the-loop approach” in response to the DOE’s BENEFIT FOA 0002090 solicitation,...

Southern California Edison (SCE) provided a Letter of Commitment in support of LBNL’s proposal for the EPIC GFO 19-301 Group 4 EPIC solicitation, intending to cost share $300,000 ($150k / $150k from ET/DR). The project will develop and demonstrate an open-source energy and load management system...

The goal of this project is to assess the energy and demand savings resulting from a solar assisted direct expansion (DX) system.  A field test was conducted in a 1,600 sq. ft. single-story residential home located within SDG&E territory. In this test, an emerging technology that consists...

The emerging technology is a National Sanitation Foundation (NSF) certified food product simulating sensor medium that changes the existing ‘air-temp’ thermostat into a ‘food-temp’ thermostat in a refrigeration unit. By enclosing the existing temperature sensor in a...

This study compared the effectiveness of remote HVAC monitoring with FDD to the traditional residential quality maintenance baseline. The emerging technology is an add-on unit and works on most residential HVAC systems, tracking the performance of an HVAC system real-time through 10 sensors...
