Evaluating Opportunities in Advanced Daylighting Retrofits

Interior lighting remains a large component of electricity use in non-residential buildings. In California, electric lighting has both a direct effect on peak load, and an indirect effect by increasing cooling requirements during summer peak hours. Effective daylighting combined with electric lighting dimming controls can directly offset electric lighting energy by reducing lighting levels when necessary to reduce the load on the cooling system.

Adaptive Sensor-Based Lighting for Security Applications

Traditional outdoor lighting technologies operate at full power throughout the night, even when areas are vacant.  This extra load, energy waste and light pollution can be averted by updating the lighting system with energy-efficient light sources and lighting controls.  By installing these technologies, adaptive lighting strategies can be implemented that provide the right amount of light when and where it is needed.  

Integrated Building Control Retrofit Package for Commercial Applications

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.

DC Building-Scale Microgrid Platform

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.

Dynamic Exterior Lighting for Energy and Cost Savings in Department of Defense Installations

03/01/2015

Exterior lighting for streets, roadways, parking lots, and other outside sites represents nearly 10% of the electricity consumed on military bases. Lighting in these areas typically consists of high pressure sodium or sometimes metal halide lamps that are normally controlled by photo-sensors located centrally or sometimes on each fixture. This limited functionality includes turning the lights on in the evening and off in the morning regardless of occupancy levels, thereby consuming more electricity than necessary.

CLTC Helped To Successfully Commercialize Next-Generation Sensor

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.

Advanced Outdoor Lighting Control Systems

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.

Codes and Standards Enhancement—Quality Demonstration Program

09/24/2014

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.
