Delta announced its LEED Zero Energy-certified Americas headquarters green building in Fremont, California, is expected to achieve a significant 57 percent reduction in annual lighting electricity consumption. This accomplishment is attributed to the recent integration of a total solution featuring systems from three Delta Group companies: cutting-edge Carisma LED lighting systems from Amerlux, smart building management software from LOYTEC and Delta Controls, along with Bluetooth low-energy drivers and multi-sensors.
In 2022, Delta Electronics' Americas headquarters became the first green building in Fremont and the second in the Silicon Valley Bay Area to achieve LEED Zero Energy certification from the U.S. Green Building Council. Before the installation of the Carisma LED lighting system and the integration with the Bluetooth connectivity platform and daylight harvesting, the building is estimated to consume an average of 136,500 kilowatt hours (kWh) on lighting per year; afterward, consumption is expected to drop to just 58,760 kWh, resulting in a 57 percent decrease in annual electricity consumption.
Carisma LED pendant lights only consume 78.3 watts. They can also be retrofitted with automation capabilities like Bluetooth control from Delta’s BABG and occupancy-sensing and daylight harvesting multi-sensors provided by LOYTEC, which integrate features to detect people’s presence and adjust artificial lighting accordingly. Delta estimates these enhancements could cut energy consumption by another 45 percent on top of the savings realized by switching to LED. Additionally, the lighting control retrofit requires no extra efforts due to the wireless technology implemented.
“Lighting controls can be done by groups, occupancy or schedule—or all three,”says Laurence Mu, facility maintenance technician at Delta. The key was to use enteliWeb by Delta Controls, a web-based building management system interface that allows for each monitoring and management of building systems through a user-friendly graphical interface.
“The system can be tied to a building automation system and, more specifically, HVAC,” he adds. “This is a whole ecosystem in a sense, all by switching the lights and adding automation capabilities.”
Employees at the Delta Electronics Americas headquarters have embraced the brighter, cooler lighting, resulting in increased productivity and simplified maintenance. Delta Electronics plans to expand the installation of Carisma LED lighting, alongside other solution integrations, across its facilities.
