Strategic approach to optimize aeration efficiency in wastewater recovery facilities to significantly reduce blower(s) usage and provide demand response...

The primary objective of this project was to demonstrate energy savings in the small and medium sized business sector by means of low-cost technology retrofits that leverage advances in intelligent advices and lower-cost networked controls. The primary project learnings showed:Recruiting SMB...

This report details findings from the evaluation of a remotely controllable, Wi-Fi-connected plug load controller. This is a case study of the deployment of 100 devices at one office building. The plug load controllers are remotely programmed to turn off power based on a pre-determined...

GTI independently and objectively conducted laboratory testing to compare the efficacy of venturi steam traps by three manufacturers against comparably-sized mechanical steam traps at different pipe sizes, pressures, and condensate loads. Venturi steam traps provided by Thermal Energy International...

The 5 MegaWatt Energy Storage Systems (ESS) are being evaluated as a Demand Response Load shedding system for commercial customers.  In addition to Demand Response, the systems shift load from on-peak time periods to off-peak time periods. The ESS functions by supplementing grid supplied...

Increased electrification of residential end use fuel types are expected as a result of activities promoting achievement of Zero Net Energy (ZNE) buildings. Because of this, there is much interest in the opportunities associated with electric water heaters. Retrofit controls are available for water...

This project builds on the 2016 Emerging Technologies report (https://www.etcc-ca.com/reports/field-assessment-residential-radiant-ceiling-panel-space-conditioning-systems) based on testing two types of radiant ceiling panels coupled with air-to-water heat pumps (AWHPs). Performance in the...

This study was a continuation of the Central Valley Research Homes (CVRH) project. The CVRH project converted four existing single family buildings in Stockton, California into unoccupied laboratory houses to study residential energy saving opportunities. Variable capacity heat pump (VCHP) systems...

This project will evaluate dedicated LED track lighting systems, which do not allow for conversion to other source types. Additionally, the use of LED screw-base lamps for use with traditional track lighting, current limiting devices and phase-cut dimming controls will be evaluated at both line and...

This laboratory assessment compares the performance of low-temperature horizontal display case with natural refrigerant (propane or R-290) and conventional refrigerant...
