Southern California Edison (SCE) is planning to produce a publication that contains case studies of residential buildings that were designed and built to achieve zero net energy (ZNE) performance and for which post-occupancy energy performance data have been obtained. The focus of the case study...

Conduct AMI data analysis of individual commercial customers using the AMI Customer Segmentation (AMICS) modeling approach. The California Public Utility Commission (CPUC) recently approved Southern California Edison’s (SCE) application for a High Opportunity Programs or Projects (HOPPs) HVAC...

Project to compare predictions from two energy simulation software’s to determine which building energy simulation engine is (more) accurate by identifying and investigating significant deviations between building energy simulation’s predicted performance versus actual performances for simple...

Provide an internationally recognized performance standard whereby different evaporative pre-cooling technologies can be...

This project is an aggressive multi-disciplinary, comprehensive, whole building approach to designing and constructing a net zero energy retrofit of an existing low-income multi-family complex. To the best of our knowledge this will be the first Multi-family Net Zero/ Deep Energy Reduction (DER)...

Laboratory refrigeration has not been extensively studied, with the exception of ULT freezers.  The largest insight into the energy savings potential comes from the ENERGY STAR Product Specification for Laboratory Grade Refrigerators and Freezers, published in 2016.  Data from 14...

Most building power distribution systems use alternating current (AC). This significantly influences the design of connected, direct current (DC) appliances including light-emitting-diode (LED) light sources and digital controls.  With the proliferation of DC devices as standard design...

This project is a laboratory evaluation of commercial plug load controls. The control devices connect wirelessly to the cloud and can report energy usage data. These devices are specific to commercial applications. The objective of the evaluation is to test the controls capability of the devices,...

The objective of this project was to evaluate the possibilities for Demand Response (DR) using connected ecosystems currently available in the market. Current residential demand response programs focus on the control of single communicating devices such as Direct Load Control (DLC) switch connected...

This study demonstrated how existing constant air volume (CAV) RTUs may approximate a variable air volume (VAV) system to increase efficiency and comfort for the building’s occupants. Given that 60% of the U.S. commercial floor space is served by CAV RTUs, these dynamic air balancing systems...
