This is a joint effort between Lawrence Berkeley National Laboratory (LBNL), Sempra Utilities, and Southern California Edison to incorporate energy efficiency measures for data centers to be used in computer building...

Project SummaryThis assessment project will determine the potential demand and energy savings, as a function of hotel room occupancy rates, for replacing existing guest room bathroom wall switches with wall switches with a built-in occupancy sensor and LED nightlight. This new energy efficiency...

Project Summary This project develops and implements variable refrigerant flow (VRF) algorithms into the eQUEST building energy simulation program. While VRF systems are applicable to both residential and small-to-medium-sized commercial facilities, this project is limited to residential heat...

Project SummaryThis project demonstrated the functionality of a refrigerant based energy storage (RBES) for air conditioning (A/C) system under different cooling load conditions. The RBES A/C system is designed to shift on-peak A/C demand to non-peak periods. It applies to buildings with a cooling...

Project SummaryIn this project, a demand control lighting (DCL) system was installed in a portion of a retail hardware store to evaluate the demand response effectiveness of this technology. Most lighting control systems turn lighting circuits on or off and are hardwired to an energy management...

Project SummaryProgrammable communicating thermostats let home owners adjust their thermostat to reduce cooling/heating loads and save money. The technology also gives Southern California Edison (SCE) the opportunity to better understand usage patterns and reduce demand during peak periods. But...

Project SummaryOccasionally, the utility electric grid systems undergo voltage fluctuations caused by faults. These faults are caused by storms, accidents, debris on lines, and equipment failures. Normally, protective relaying is used to disconnect the problem lines and then voltage automatically...

Project SummaryTypical demand response programs require curtailments of 15 percent of demand or 50 kilowatts (kW), whichever is greater, with some programs imposing heavy penalties for non-performance or underperformance. The rationale for automated shallow response project (ASDR) is that more...

Project SummaryIn this project, a wireless energy management system was installed in a government office building to evaluate the demand response effectiveness of this technology. The wireless system investigated in this project used modular components which could be activated by either the...

Project SummaryThis study provides an energy savings comparison of five different types of hand dryers: standard manual, energy efficient manual, standard automatic, energy efficient automatic and high velocity automatic. A standard automatic hand dryer and a high velocity hand dryer were installed...
