LD+A Research Matters: Optimizing Your Workout Environment — How Lighting Impacts Exercise

When it comes to physical training, the environment individuals choose can significantly enhance their performance. A recent study by Professor Dongwoo Jason Yeom and Ph.D. student Seonghyuk Son of Arizona State University and Professor Jae Yong Suk of the California Lighting Technology Center at the University of California, Davis explores indoor lighting and its influence on physiological signals in humans during exercise.

LD+A Research Matters: Maximizing Energy Savings with Optimized Dimming Ramp Rates in Retail and Museum Buildings

According to a study conducted by the U.S. Department of Energy, lighting accounts for 18% of the energy used by commercial buildings in the U.S., making lighting upgrades with controls a significant opportunity for energy savings. When properly designed, today’s LED technology pairs well with advanced controls. One example of a lighting control strategy typically used in circulation spaces for commercial buildings like offices and schools is occupancy sensing, which automatically turns lights off when spaces are unoccupied and turns lights on when spaces are occupied.

Pilot-Scale Evaluation of Integrated Building Control System for Commercial Buildings

The California Lighting Technology Center, in collaboration with the California Energy Commission, conducted research to refine and deploy technology strategies that integrate and optimize automated controls for heating, ventilating and air conditioning, electric lighting, and dynamic fenestration (window and door) systems. Project objectives were:

1. Refine and publish an integrated building control system specification for commercial applications including necessary hardware and software components.
