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 collaborated with the Emerging Technologies group at the Pacific Gas & Electric Company to evaluate linear LED lamps in a variety of fixture applications as well as identify any interoperability issues.
Widespread adoption of LED lighting for general illumination applications is poised to be the single, largest advancement in lighting efficiency during the 21st century. Due to its potential, a variety of market actors have introduced LED products and made associated performance claims that have set the technology up with somewhat unrealistic expectations regarding system efficacy and longevity. To compete in this market, LED manufacturers have focused on research to improve efficacy and reduce product costs, often at the expense of product quality and feature optimization.
CLTC, in partnership with Southern California Edison, completed a project portfolio from 2014-2018 to assess controls, lighting, and daylighting technologies and their potential for commercial applications. The projects have elements of market assessment, EM&V, and selected demonstrations.
The project focus is on evaluating the following technologies:
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.
Lighting projects that involve updating CFL lighting systems should consider all viable retrofit options. When retrofitting between CFL four-pin lamps and LED solutions, it is important to observe safety precautions and consider performance variables.
Linear fluorescent lamps account for 83 percent of installed lamps in the California commercial sector per a lighting market characterization performed in 2014. LED lighting products are receiving attention for their potential to replace fluorescent lighting, reduce energy use and improve lighting quality in a variety of indoor commercial applications, including offices, classrooms and retail stores. LED alternatives to linear fluorescent lighting products fall into three main categories: linear retrofit lamp solutions, linear retrofits for troffers and dedicated luminaires.
California’s 2013 Title 24 requirements for building energy efficiency call for some high-efficacy lighting in a limited number of residential space types, such as kitchens and bathrooms. A future code requirement that all residential lighting be high efficacy has the potential to yield significant energy savings across the state, but implementation must first be proven practical and cost-effective.
