Daikin completes solar plant to power massive Houston-area campus

switched on

Japanese HVAC company Daikin Industries has completed a nearly one-megawatt solar power plant at its Daikin Comfort Technologies North America campus southeast of Waller.

Daikin says the new plant at its 4.2 million-square-foot Daikin Texas Technology Park will eliminate an estimated 845 metric tons of carbon emissions each year. The park houses the largest HVAC factory in North America.

“Daikin’s unwavering commitment to innovation drives us to continually perfect the air we share. With the launch of this solar project, we’re one step closer to being a net-zero CO2 emission factory by 2030,” Nathan Walker, senior vice president of environmental business development of locally based Daikin Comfort Technologies North America, said in a release. “This installation is a significant step in reducing our carbon footprint and underscores our commitment to energy efficiency, sustainability, and environmental stewardship.”

Solar power from the new facility will power the Daikin campus’ central chiller plant, which circulates about 125,000 gallons of chilled water annually and 75,000 gallons of hot water in the winter. Also, the solar setup is designed to connect to the electric grid that serves the campus. About 10,000 people work at the campus.

Daikin, a Fortune 1000 company, may not have been a familiar name to some Houstonians until January, when it took over the naming rights for the Houston Astros’ stadium. The naming rights agreement for Daikin Park, formerly Minute Maid Park, expires during the Astros’ 2039 season. The stadium had been named Minute Maid Park since 2002.

“The Astros are the pride of Houston, an organization that has built resiliency in hard times, and have succeeded to be a winning team. The coming together of both our organizations is a symbol of our love for our hometown and the communities of the Greater Houston area,” Takayuki “Taka” Inoue, executive vice president and chief sales and marketing officer at Daikin Comfort Technologies North America, said in November.
