Haiku Fans


Top green builder DPR Construction specializes in creating energy-efficient office spaces, but its own office in San Francisco – typical leased space in a high-rise – was anything but green. The company chose to move into a new office that embodied its core values, but no existing spaces in the city met its stringent requirements. To prove green renovations are cost- effective, DPR leased a two-story building and set out to renovate it into the greenest net-zero office in San Francisco. Among the hurdles faced by the firm was a need to keep employees comfortable without relying solely on energy-intensive HVAC.


DPR turned to Big Ass Fans®, which previously installed energy-efficient ceiling fans in the company’s Phoenix and San Diego offices. DPR selected 10 Essence® and four Haiku® fans to work in tandem with an energy- efficient HVAC system. Gentle breezes provide up to a 10°F (5.5°C) cooling effect using a fraction of the energy of air-conditioning. The fans also distribute heated air quickly and efficiently after overnight temperatures dip, allowing the firm to run the heaters for just a few minutes in the morning. This progressive comfort solution contributes to DPR’s pursuit of LEED® Platinum and net-zero certifications.
