The California Lighting Technology Center, in collaboration with the California Energy Commission, is conducting research to develop and evaluate technology that integrates automated controls for heating, ventilating and air conditioning (HVAC), electric lighting and dynamic fenestration systems. The integrated system is referred to as the Integrated Building Control Retrofit Package (IBCRP), as it is aimed for retrofit projects in existing commercial buildings.
CLTC is partnering with Bosch to demonstrate the Bosch Direct Current Building-Scale Microgrid Platform (DCBMP) at an American Honda Motor Co., Inc. warehouse facility. Bosch will demonstrate the effectiveness of the DCBMP, a commercial-scale DC building microgrid that integrates advanced technologies to provide reliable power to the connected loads, resilience during grid outages, increased building energy efficiency and renewable energy utilization.
CLTC researchers are developing a standard methodology for conducting field demonstrations to better inform energy codes and standards enhancement.

The commercialization of Echelon's Lumewave MWX-LVE long-range outdoor microwave sensor illustrates CLTC's success in supporting advanced sensors for adaptive outdoor applications.
CLTC demonstrated and supported the next-generation sensor, which detects movement and can distinguish between slow and fast moving objects such as pedestrians, cyclists and motorized vehicles. The sensor reacts to the size of objects from longer distances, automatically raising the light levels to high output when the areas are occupied and lowering them when areas are vacant.
The California Lighting Technology Center partnered with San Diego Gas & Electric and two Southern California cities on a project to help accelerate the adoption of energy-efficient advanced outdoor lighting control systems.
The project evaluated outdoor wireless lighting control systems that allows for remote operation and monitoring of fixtures using a web-enabled central management system. Laboratory and field assessments were conducted for separate systems installed as part of citywide retrofit projects in San Diego and Chula Vista.
The CASE-Q DP Program Manual contains the requirements and processes for future field demonstrations. It can be used by any team wishing to conduct a sound, thorough and well-documented technology demonstration. In addition to providing this resource, the CASE-Q DP directly supports identification, selection, installation and performance assessments of energy-efficient building technologies ready for current or near-term inclusion in California's Codes and Standards Enhancement (CASE) initiatives.
UC Davis News and Information—As ambulances at a Vacaville hospital speed off to their next patient, an ultrasmart, energy-efficient system is lighting the way. Installed in partnership with the University of California, Davis, the lighting system now illuminates the emergency vehicle routes, parking lots and outdoor walkways of the NorthBay VacaValley Hospital. The system is reducing outdoor lighting energy use at the 24-hour site by 66 percent, saving about 29,000 kilowatt-hours annually -- enough to offset the greenhouse gas emissions of 7.2 tons of waste.
In 2013, UC Santa Barbara partnered with the SPEED team to demonstrate network controlled LED lighting for streetlights and post-top fixtures. These exterior fixtures were purchased with dimming power supplies and equipped with radio frequency (RF) control modules. The post-top fixtures were also equipped with occupancy sensors. These lighting controls allowed all the units to be incorporated into an adaptive mesh network control system that optimized the fixtures’ energy efficiency and gave the campus unprecedented control of its lighting.
The combination of occupancy controls, a bi-level generator, and an induction source produces an energy-efficient luminaire with exceptionally long life, good color quality, and dynamic light level response based on actual usage. The bi-level controls contribute additional savings that are directly proportional to automotive and pedestrian traffic patterns. Bi-level luminaires reduce to 50% power on vacancy and increase to 100% power on occupancy.
