Digital energy and technology firm Delta Electronics’ headquarters for Americas operations has joined a small group of buildings earning LEED Zero Energy certification from the U.S. Green Building Council.
The LEED—for Leadership in Energy and Environmental Design—Zero Energy certification is only the second such building distinction awarded to facilities in the Silicon Valley Bay Area of northern California. Delta’s Americas HQ is in Fremont, Calif.
The certification is for buildings which generate as much electricity as they consume. The Delta Electronics HQ includes a new solar photovoltaic carport and 330-kWh Delta energy storage system.
“Fremont has been Delta’s home in the Americas for over 30 years, so it is an honor for us to contribute to our community with the environmental and social benefits of the city’s very first LEED Zero Energy green building,” Kelvin Huang, president of Delta Electronics Americas, said in a statement. “With its net-zero energy capabilities, our Americas HQs green building will contribute even further to Delta’s RE100 initiative, which is a promise to power our worldwide operations with renewable electricity by 2030. By developing smart energy-saving solutions capable of fostering green buildings and sustainable cities, Delta demonstrates that its ESG-embedded business model can bolster mankind’s environmental goals.”
The Delta facility can generate more than 1.4-million kWh of renewable electricity through the 616-kW rooftop solar array and a recently constructed 504-kW bi-facial PV carport system. Both are connected with Delta’s own PV inverters to convert direct current to alternating current.
The energy output should equal 100 percent of the buildings’ consumption over a full year, according to the company.
Delta also installed an enhanced energy efficiency solution to its data center cooling system. The dedicated economizer is supported by Delta DC brushless electronically commutated fans and variable frequency drives for the heating, ventilation and cooling applications.
Those improvements have lowered the data center energy usage impacts, according to Delta.
“Delta Electronics sets another milestone as only the second facility in the entire Bay Area to achieve LEED Zero-Energy,” said Lily Mei, Mayor of Fremont. “As one of the greenest cities in the nation, we're proud that Delta Electronics continues to showcase sustainability through thoughtful application of technology, including using its Fremont facility as a proving grounds for many of its own products while working through pandemic disruptions to invest even further in our community.”
Taiwan-based parent company Delta Electronics is a global manufacturer of industrial and computer fans and power systems components. It has more than 200 facilities worldwide.
Officially, so-called "net zero buildings" are still rare but growing in scope in the U.S. Boston University recently contracted Schneider Electric to manage its geothermal-connected Computing Center on campus.
