Algorithms for Advanced Lighting Control & Energy Management

Algorithms for Advanced Lighting Control & Energy Management

With support from a CITRIS seed grant, researchers at CLTC and UC Berkeley are working together to develop advanced lighting control algorithms that make use of multiple data streams, both local and remote, to improve lighting and energy management in buildings. Applications include electrical lighting systems in commercial spaces with windows and/or skylights.

Multi-Tenant Light Commercial Buildings

Multi-Tenant Light Commercial Buildings

CLTC is partnering with the UC Davis Energy Efficiency Center (EEC) to address untapped efficiency opportunities in the Multi-Tenant Light Commercial (MTLC) building sector. The project is focused on identifying and overcoming the biggest barriers to energy-efficiency retrofits in the MTLC market. More than half of the energy-saving contributions of the team's proposed solutions will come from lighting-related retrofits, as the group hopes to reduce interior lighting energy consumption by 20% and exterior lighting energy consumption by as much as 50%.

Adaptive Envelope Systems for Retail & Agriculture

Adaptive Envelope Systems for Retail & Agriculture

CLTC collaborated with the California Energy Commission and the California Institute for Energy and Environment (CIEE) to develop adaptive envelope technologies for retail and agricultural buildings. The objective was to develop systems that optimize both lighting and thermal efficiency in these facilities, using advanced fenestration materials, daylighting technologies and lighting controls.

Western Exterior Occupancy Survey (WEOS)

Western Exterior Occupancy Survey (WEOS)

CLTC partnered with Bonneville Power Administration, Pacific Gas and Electric Company and Southern California Edison to survey occupancy at four test sites in California and four test sites in Washington State. The sites selected for the research study represent market sectors identified as having the greatest potential to achieve energy savings with exterior adaptive lighting solutions.

Networked LED Streetlights with Intelligent Controls

Networked LED Streetlights with Intelligent Controls

CLTC has collaborated with the City of Davis to field-test a network-controlled LED street lighting system along Second Street in Davis, CA. The project team will demonstrate and measure the effects of various sensor technologies and communication protocols for adaptive street lighting, in terms of performance characteristics and energy savings. The demonstration involved replacing 12 high-pressure sodium (HPS) fixtures with LED streetlights and retrofitting 14 existing LED fixtures with dimming capabilities and controls.

Ultra-Smart Exterior Luminaires

Ultra-Smart Exterior Luminaires

“Smart” luminaires use integrated sensors to adapt light levels based on available daylight and/or occupancy patterns; “ultra-smart” luminaires function similarly, but they are also capable of communicating with one another through wireless radio frequency (RF) connections. This RF networking allows the luminaires to operate as a larger system. Different luminaire types can be incorporated into the network, including wall packs, post-tops, parking lot luminaires, and streetlights.

CLASP Project: LED Replacement Lamp Testing

CLASP Project: LED Replacement Lamp Testing

The Collaborative Labeling and Appliance Standards Program (CLASP), an international nonprofit, partnered with CLTC to conduct laboratory testing of LED lamps currently available in the U.S. market. Data collected and analyzed in the course of testing helped the California Energy Commission develop a voluntary quality-based performance specification for screw-base LED lamps, with requirements for color characteristics and dimmability. CLASP and CLTC are also assisting the Energy Commission in developing a test methodology for measuring these quality characteristics.
