Delta Electronics (Americas) Headquarters Gets Award for Net-Zero Energy Design

January 25, 2019 by Scott McMahan

Delta Electronics Americas reported that its headquarters in Fremont, California won the First Place Honor Award in the National Institute of Building Sciences' 2018 Beyond Green™ High-Performance Building and Community Awards. This prestigious award recognizes the innovative eco-friendly features and net-zero energy design of the LEED Platinum-certified facility.

Delta Electronics says that the award and the LEED Platinum certification were enabled partly as a result of the integration of Delta's own smart energy-saving systems, including building automation, electric vehicle (EV) charging, elevator energy regeneration, green data center, solar PV energy generation, and LED lighting.

"This was an ambitious project that we hope can be emulated by other organizations throughout California, the United States and the world," said M.S. Huang, president of Delta Electronics (Americas). "Corporate social responsibility has long been a vital component of our business model. As part of our mission, Delta has promoted green building concepts since 2006, creating 27 eco-friendly facilities around the globe to date. The Americas headquarters is a living testament that eco-friendly facilities are the foundations of sustainable cities."

"Delta's commitment to its community and employees through this high-performance building is evident," said Nancy McNabb, AIA, Beyond Green™ juror and principal at McNabb & Associates. "Demonstrating how its products can contribute to high-performance buildings across the country is equally admirable."

Completed in October 2015, the LEED Platinum-certified building was carefully designed to ultimately achieve net-zero energy while keeping in mind sustainablility as well as aesthetics.

The company's building design uses a variety of innovative energy-saving systems and solutions to net-zero energy through a variety of innovative energy-saving systems and solutions, including:

The facility gets its power from a 616kW rooftop PV system featuring Delta's high-efficiency inverters. The installation of a 500kW bi-facial carport PV system in 2019 will further boost energy generation.

Also, variable frequency drives manufactured by Delta are critical components of the facility's HVAC system, which is supported by a geothermal heat exchanger that circulates 12,000 gallons of water through 92 miles of pipes, reducing HVAC-related energy consumption by up to 60 percent.

Delta's LED lighting products help the facility save roughly 50 percent more energy compared to traditional luminaires.

A green data center with annual power usage effectiveness (PUE) as low as 1.37, enabled with Delta's energy-efficient InfraSuite Datacenter Solution. The facility uses the Delta Energy Online energy monitoring software.

Nineteen Delta EV chargers (AC EVSE and fast DC) promote e-mobility among employees, and a 140,000-gallon rainwater harvesting system irrigates landscaping and provides water for toilets, with uncollected rainwater directed to a bioswale.

In addition, the company says that 20 percent of the building materials were reclaimed.

The National Institute of Building Sciences organizes the Beyond Green™ High- Performance Building & Community Awards each year. This program acknowledges the initiatives that shape, inform and promote the high-performance building market, as well as the real-world application of high-performance design and construction practices.
