Ubiquitous Communication by Light

Ubiquitous Communication by Light

Ubiquitous Communication by Light (UC-Light) is an emerging technology that uses visible light to perform wireless machine-to-machine communication. The mechanism at work with UC-Light is similar to the infrared technology used in TV remote controls, but UC-Light uses visible white light from modulated light emitting diodes (LEDs). Visible light communication (VLC) is potentially cheaper than conventional wireless communications because VLC can use pre-existing LED luminaires for communication purposes.

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 is collaborating 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 is to develop systems that optimize both lighting and thermal efficiency in these facilities, using advanced fenestration materials, daylighting technologies and lighting controls.

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.
