Beijing's Haworth Showroom Named World's First LEED v4 Certified Project

by , 10/25/13

The Parkview Green itself is already a marvel of sustainable architecture: The 800,000 sq ft mixed-use development features a glass and ETFE envelope that minimizes heating and cooling demands all year long. When heat or air conditioning is required, energy is supplied by a geothermal system. The development also collects rainwater from the roof and paved areas, which is then filtered and recycled for use as irrigation water.

Inside the building, Haworth’s showroom reveals even more green surprises. “Inside Parkview Green, Haworth has created the Club, a workspace concept that offers coworking and lounge spaces that can be used by the building’s tenants, hotel guests and members in the community. Everything from partition walls, meeting rooms, huddle spaces and private focus areas can be rearranged to meet the day-to-day needs of its users,” reports Environmental Leader. This flexible-use design saves money and time, and reduces waste.

In building the showroom, 60 percent of nonstructural interior elements were reused. All interior paints, adhesives and sealants meet the strictest chemical content and VOC limits, so air quality inside the showroom exceeds the indoor environmental air quality requirements by 35 percent.

To reduce energy consumption, the designers installed variable air volume (VAV) air diffusers under the floors. These diffusers work in conjunction with cold radiation ceilings to provide individual controls for the temperature of each solar exposure and interior space. An optimized HVAC system and LED lighting design, fixtures and controls supplied by Philips, further reduced energy consumption by 59 percent (compared to ASHRAE energy requirements).

A greywater recycling system and efficient faucets and toilets reduces water consumption by 53 percent. And just for good measure, 93 percent of the furniture in the space is either Greenguard certified or was repurposed from an existing showroom. Haworth also purchased renewable energy credits equivalent to five years of the showroom’s energy use, a practice that’s duplicated across all of its international LEED projects.
