Adaptive Exterior Lighting for the Health Care Sector

Post-retrofit lighting and controls at VacaValley Hospital, Vacaville, CA

The California Lighting Technology Center (CLTC), Lawrence Berkeley National Laboratory (LBNL), and the U.S. Department of Energy recently completed a state-of-the-art lighting system demonstration at NorthBay VacaValley Hospital in Vacaville, California. On March 19th, 2014, the project received an award for “Best Use of Lighting Controls in a Single Facility” from the Lighting Energy Efficiency in Parking (LEEP) Campaign.

Retail Showcase & Market Survey

Retail Showcase & Market Survey

CLTC partnered with Pacific Gas and Electric Company (PG&E) and the California Energy Commission to create Lux, a retail lighting showcase that lets boutique owners see, firsthand, how LED lamps perform in a realistic store setting. The space includes information and demonstrations of LED parabolic aluminized reflector (PAR) lamps, primarily PAR 38 lamps, and smaller multifaceted reflector (MR) lamps, MR 16s, used most commonly for accent lighting in retail applications.

SPEED Program

State Partnership for Energy Efficient Demonstrations (SPEED) Program

The California Energy Commission sponsors the development and demonstration of energy-efficient, environmentally safe building technologies. It does this, in part, through the State Partnership for Energy Efficient Demonstrations (SPEED), a program that demonstrates innovative lighting and HVAC technologies. The SPEED program is managed by the California Institute for Energy and Environment (CIEE), which is a branch of the University of California. The California Lighting Technology Center (CLTC) is subcontracted by CIEE to develop and implement lighting technology demonstrations.

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%.
