Evaluation of High Efficiency Lighting for New California Homes

06/19/2015

Current Title 24 Building code requirements call for use of high-efficacy lighting in a limited number of residential space types. Builders are allowed to install low efficacy lighting if they also install dimming controls. However, significant load reduction and energy savings over current code-compliant designs can be achieved through the use of All High-Efficacy (AHE) lighting design practices.

LED Linear Retrofit Solutions and Advanced Lighting Control Systems for Small Commercial Retail Applications

06/09/2015

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.

MR-16 LED Replacement Lamps: Electrical Compatibility and Performance

05/01/2015

As light emitting diode (LED) MR16 lamps become more prevalent in the commercial market, both residential and commercial end‐users are considering these lamps as replacements for currently installed halogen incandescent MR16 sources. While the energy savings associated with LED lamp replacements is evident, the compatibility of LED MR16 lamps with existing electrical hardware is not. In one‐to‐one lamp retrofits, MR16 LED lamps often demonstrate negative performance characteristics such as visible flicker and audible humming.

Core Concepts

LD+A— Core sunlighting is a practical, natural alternative for interior illumination deep within a building. Unlike other solar technologies, core sunlighting involves capturing sunlight at the building envelope, concentrating it, transporting it and regulating its release deep within the building at useful indoor lighting levels, typically only 1 percent of outdoor illumination. Significant electrical energy savings can be realized if the system incorporates automated electric lighting controls that substantially dim or completely turn off the electric lights.
