Advanced Lighting Control Systems: Bench Testing

11/04/2015

Advanced lighting control systems provide networked control and monitoring capabilities of connected luminaires via onboard metering and system reporting features.  These advanced features allow system owners to dynamically balance visual comfort and lighting energy use.  CLTC, in collaboration with SDG&E, developed a technology validation program to determine the accuracy and reliability of onboard metering and system reporting features of advanced lighting control systems.

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.

Saving Energy in Buildings with Adaptive Lighting Systems: Solutions for the Retail Sector

06/15/2015

The retail sector, which represents 13 percent of California’s lighting electricity use, has historically not embraced the use of lighting controls to save energy. California regulators have responded to retailer’s concerns that lighting controls and lighting power density restrictions may have a negative impact on sales and customers. Currently, building lighting energy-efficiency standards for the retail sector are less stringent than regulations imposed on other commercial space types.

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.

Field Luminance Mapping of the Sky

11/01/2010

IES Annual Conference 2010—When sky luminance distributions are measured far from a laboratory facility, portable and inexpensive instruments are useful. High dynamic range (HDR) photography has become a practical method for sky luminance mapping. However, long exposure photography directed at the sun can cause severe damage to digital camera sensors. To avoid this problem, a system was designed that integrates an adjustable shading disk with an HDR camera.

Adaptive Outdoor Lighting for the Health Care Sector

07/14/2014

In 2014, NorthBay VacaValley Hospital became one of the first U.S. health care facilities to install a network-controlled adaptive outdoor LED lighting system. The hospital already had up-to-date, energy-efficient outdoor lighting installed, yet this award-winning installation reduced the hospital's outdoor lighting energy use 66.4%. Energy savings correspond to occupancy rates of 35–55% observed at different areas of the site.
