This study investigates the energy savings capability and potential of ultra-low temperature freezer monitoring systems when used as an energy consumption diagnostic tool. Ultra-low temperature (ULT) freezers are common in university labs and facilities involved in research and development...

Four different retrofit RTU controllers were tested on four 7.5 ton heat pumps serving office space at one building in San Diego. The operation of those units was alternated on a weekly basis from baseline to retrofit mode. Proper operation of the each controller was verified and the features of...

In many cases, buildings lack automatic ventilation feedback and are consequently over-ventilated. This report investigates the potential energy savings for a demand control ventilation (DCV) system with centralized air quality sensors. This technology aims to maintain or improve building comfort,...

This review investigates the demand response (DR) and control capability of a Home Area Network (HAN) technology with Smart Appliances. Secondly, it discusses energy savings potential, ease of installation, and user feedback on the technology. This review describes in detail the technology and...

This study investigates the demand response (DR) capability and potential of a controller which can lower the speed of variable speed pool pumps. The vast majority of incumbent pool pumps are single speed and can only be turned off for DR measures. Variable speed pool pumps have the ability to...

A side-by-side comparison was done with the conventional technology, MH HID, and the emerging technologies, LED and induction. Based upon pump island occupancy, the bi-level light sources would allow for the under-canopy lights to be further dimmed to a light level acceptable to the station’s...

This project partnered with ACE Hardware’s Distribution Center located in Rocklin, CA and tested the integration of High Bay Light Emitting Diode (LED) lighting fixtures with integrated sensors and an aggressive Advanced Lighting Control System (ALCS) to realize the deepest energy savings possible...

The primary goal of this project was to develop a complete, standardized auditing procedure that PG&E field representatives, consultants, or water agencies themselves could perform on municipal water systems. The procedure was to be a simple audit, requiring limited time, measurements, and...

The Gas Technology Institute proposed and executed this 36‐month research program of closely linked projects to help facilitate the overall goal of reducing natural gas consumption for residential water heating in California. Using guidance from the Energy Commission’s Public Interest Energy...

The goal of this project was to evaluate the economic and technical viability of a comprehensive LED retrofit for all major fixture applications within a Fry’s Electronics store in Northern California. This includes general service fluorescent lighting, general service incandescent lighting,...
