The technology to be evaluated is an automated, smart, internet connected zone control system for residential HVAC. This first phase of a two phase project will complete lab tests to verify that the zone control system can regulate comfort while not degrading overall system efficiency, while also...

The main goal of this Project was to characterize the behavior of radiant heating and cooling systems in order to provide information for designers that would reduce both the cost and the perceived risk associated with radiant systems. The aim is to improve energy and comfort performance by...

Title 24, part 6 requires non-residential buildings be built and commissioned with several components of automated demand response infrastructure. There is a code compliance “industry” that has evolved as a result of past building commissioning requirements and the need to ensure that...

CAISO has telemetry requirements for Proxy Demand Resources (PDRs) that are greater than or equal to 10MW or provide ancillary services. The ability for Demand Response Providers (DRPs) to meet the telemetry requirements in a cost effective manner could unlock more DR to be bid into the wholesale...

High efficiency conveyor best-available technologies. The energy and water savings potential at 70% nominally versus conventional conveyor dishwashers installed in commercial kitchens is promising. The real-world savings per installation is actually greater as many older dishwashers are poorly...

The objective of this assessment was to conduct a field test to evaluate the performance of a sub-wet bulb evaporative chiller (SWEC) and to characterize the performance over the range of operating conditions experienced. The cooling capacity, power draw, system efficiency, total energy...

The purpose of this study is to determine the capabilities and cost-effectiveness of a lower-cost-of-manufacture Flywheel Energy Storage (FES) System. The core of this particular FES System technology involves the development of a lower-cost steel flywheel, which will reduce the first cost of the...

The purpose of this report is to examine the impact of the available financing options and training on driving customer action towards implementing energy efficiency projects.  The Energy Efficiency Finance Team at PG&E aimed to assess a technological solution to addresses three potential...

The primary objective of this report is to assess opportunities for identifying, improving, and expanding behavior-based energy programs across a utility energy efficiency portfolio. Energy conservation behavior could deliver up to 20% reduction in energy usage, but the initial definition of...

Starting in the summer of 2016, PG&E partnered with three technology firms to develop the third-party bring your own thermostat (BYOT) pilot designed to leverage already installed smart thermostat technologies as a demand response (DR) resource that could be ramped up in a relatively short...
