Sustainability was a major drive in the headquarters’ design, with 75 percent of the building funded by ARAA and an executive order to reduce greenhouse gas emissions. Elements such as abundant daylighting; high performance glazing and exterior shading; HVAC systems that included variable frequency drives (VFD) and premium motors; plus low-flow and sensor operated plumbing fixtures all helped bring the facility to LEED Gold certification. The most creative sustainable feature however is the biomass boiler.
Combined, Interface’s building systems have significantly cut energy and water use over 40 percent less overall building energy usage (vs. ASHRAE 90.1-2004), indoor lighting energy was reduced by 30 percent; exterior by 68 percent, envelope measures reduced energy use by 9 percent, HVAC system decreased overall energy use by 12 percent, and domestic hot water use decreased 53 percent.
