SCE has identified lighting retrofit opportunities for fast food restaurants' backlit menu boards. This study will conduct field measurements in order to assess the energy savings of these retrofits. This Field study will test five different energy efficiency solutions using either T5 fluorescent...

The goal of this three-month field assessment was to determine the efficacy of a physical water treatment (PWT) technology for cooling towers to determine energy, water, and chemical savings potential at a Southern California Edison (SCE) customer...

The goals of the Field Study were to explore the technical and experience components of Connected Home products with a dual focus on assessing customers’ experience and energy impacts. Survey instruments were designed to meet most of the customer experience analysis objectives. In...

The objective of this report is to calculate electric savings achieved by the fuel cell waste heat recovery absorber system installed at UCSD. The data collected from November 15th 2016 to September 11th 2017 from the fuel cell, absorber, and electric chillers were used. The data was then used to...

DX HVAC units are very often used in standalone retail, education, restaurant, and small to medium size office buildings. Among other reasons, small DX HVAC units have this market dominance in small and medium commercial buildings because they require little site-specific design, can be dropped...

Air conditioning loads drive peak demand and contribute to overall electric power consumption in California. In the summer, cooling loads are highest in the middle of the day when air conditioners are the least efficient. Rejecting waste heat from an air conditioner to a swimming pool rather than...

Ongoing commissioning (OCx) is an innovative approach to managing buildings – it provides continuous improvement in the operation of building systems. OCx is a multi-step implementation process, followed by a step-by-step continuous improvement cycle. Implementing this process within...

This report summarizes the conducted research, sources and findings. One finding is that available information is indeed not sufficiently detailed and up to date to accurately quantify power management software savings potential. A larger scale study remains nevertheless questionable, for several...

According to a study by the California Energy Commission (CEC), the agricultural sector accounts for 79 percent of California’s water use, which corresponds to 4 percent (over 10 GWh annually) of the state’s electricity use (CEC, 2005). One potential strategy for reducing agricultural...

Phase One of San Diego Gas and Electric’s Digital Billboard Project “Digital Billboard Use in California: ET14SDG8011” consisted of a description of digital billboards’ technology, preliminary energy profile, and a California market characterization. The final report,...
