As part of our work toward Advanced Lighting Control Systems (ALCS) incentive programs, quantifying the savings from ALCS has emerged as one of the biggest hurdles in adoption. In particular, estimating and verifying savings from daylight harvesting is challenging because savings are highly...

The focus of this case study of non-intrusive load monitoring (NILM) algorithms by four vendors at 11 non-randomly selected homes in the SDG&E region was to evaluate the rough accuracy of each algorithm in an effort to better understand the state of that industry. Whole building electrical...

An occupancy-based guestroom energy management system senses when a hotel room is occupied and adjusts the energy systems—such as HVAC, lighting, and outlets—accordingly to save...

The objective of this project was to develop a functionality testing procedure for residential smart thermostat devices, in support of an energy efficiency and demand response residential smart thermostat rebate program, in the planning stages at the time of this writing. This testing procedure...

This project will look at "Gamification" to motivate people to use less energy, either by changing their behavior or by purchasing energy-efficient appliances, equipment, or buildings. Gamification is “approaching problems from the perspective of a game designer to tap into the psychology of...

The Solar Decathlon is a DOE-sponsored international competition which challenges collegiate teams to design, build, and operate solar powered houses that are cost-effective and energy-efficient. These competition homes are highly visible and typically see more than a quarter of a million visitors....

Sweetwater Spectrum, a planned community of four single-story residences and a community center located in Sonoma, CA, is designed to serve adults with autism spectrum disorders. The project was initiated as one of several zero net energy demonstrations and provided the opportunity to evaluate...

This project evaluates the lighting performance and energy savings potential of a Lamp-style Retrofit Kit, External Driver (a solution with separate lamp and driver), combined with a Wireless Advanced Lighting Control System (ALCS) to achieve additional energy savings and DR...

Scaled field placement evaluates the electrical and thermal savings for DCKV when combined with building EMS systems in order to provide work-paper updates and inform new measures. Further evaluates opportunities for chains and SMBs using a tiered pricing...

This assessment implemented and evaluates the costs and conversion challenges associated with transitioning from OpenADR 1.0 to 2.0 in various sites that already use OpenADR 1.0 to participate in PG&E automated demand response (AutoDR)...
