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.
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.
CLTC is a trusted resource for up-to-date lighting information and practical guidance on energy-efficient building technologies. We would like to introduce our new Lighting Best Practices Series with the release of two publications:
California's new nonresidential Building Energy Efficiency Standards take effect on January 1, 2017. The 2016 Standards focus on several key areas to improve the energy efficiency of newly constructed buildings, additions and alterations to existing buildings. California's Standards now align with ASHRAE 90.1 2013 standards and include more stringent lighting power density limits for many indoor and outdoor spaces. Updates enhance and simplify many aspects of the 2013 requirements including indoor lighting control requirements for new construction and alterations.
The potential to reduce energy consumption in existing and commercial buildings is enormous. On average, 30% of the energy used in commercial buildings is wasted, according to the U.S. Environmental Protection Agency. Lighting has a large potential for energy savings for any U.S. building end use, with a significant fraction of that potential coming from lighting controls.
One of the features of networked lighting controls is the ability to monitor lighting energy use over time and adjust the system to achieve the best possible performance. Facility managers can match system use to expectations and adjust system settings to result in optimized user comfort while maximizing savings. Real-time energy monitoring offered by some control systems has also piqued the interest of utility program managers in locations in the U.S. where rebates assist with the accelerated adoption of emerging technologies.
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:
Advanced lighting control systems (ALCS) 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.
CLTC is partnering with Liberty to create a zero net energy community in West Sacramento along the Sacramento River. The Liberty Lighting Guide provides design and technical specifications, application of directives, as well as Title 24 code compliance requirements for residential, outdoor, private community clubhouses, K – 8 schools, private clubhouses, neighborhood commercial spaces, parks, greenbelts, trails, sports, and recreation centers.
