As part of PG&E’s Zero Net Energy (ZNE) Pilot Program, De Young Properties designed and built a single story 2,064 square foot single family home located in Clovis, CA. It was built in 2013 and used as a model home until 2018 when it became occupied. All loads were monitored for the first...

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 different freezer...

The first phase of the SIM Home project discussed the potential effects of variations in user behavior on estimates of energy consumption for plug load devices. Three types of variations were explored: (1) the duration or number of times per day the device is used, (2) the frequency or periodicity...

A compact, Bluetooth enabled, inline digital natural gas flow meter has entered the market, with two models anticipated for 2018 market entry (Table 1.)  Both models can be installed in tight spaces and do not require venting.  The submeters are represented as being pressure independent...

The purpose of this Demand Response Emerging Technology (DRET) Assessment is to confirm that, in a laboratory setting, end-use energy consumption by certain appliances can be automatically controlled by a combination of: (1) a frequently changing (every 5 minutes) GHG intensity signal based on...

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...
