PEOPLE: owner, Emerson College, Boston; architect, KlingStubbins, Cambridge, Mass.; structural engineer, LeMessurier Consultants, Cambridge; mechanical, electrical, plumbing and fire-protection engineer, Shooshanian Engineering, Boston; contractor, Macomber Builders, Boston; and commissioning agent, Cornerstone Commissioning Inc., Boxford, Mass.GREEN POINTS: The Piano Row Residence Hall, Student Center and Athletic Facility concentrates three vital components of student life in one structure that complements the urban character of the street. The site required mitigation to remove hazardous materials from previous development. A white thermoplastic-olefin membrane on the roof reduces the heat-island effect. Emerson College pursued a water-conservation program, investing in rooftop rainwater collection to provide 100 percent of on-site irrigation needs. Low-flow fixtures inside have reduced water consumption, as well. Purchased green power meets half the building’s energy needs and low-emitting materials were specified for all sealants, adhesives, paints, carpets and woods. About 75 percent of qualified spaces receive daylighting and 90 percent of qualified spaces have views. Eighty percent of the construction waste was diverted from landfills. The U.S. Green Building Council, Washington, D.C., rated the facility LEED for New Construction Certified.
