"Green building... is the use of recycled and nontoxic materials, solar or thermal heating, natural sunlight, and natural ventilation so that buildings have a minimal impact on the planet. Historic preservation...[save] the value of turn-of-the-century structures that fit humanely into the urban fabric and have interior and exterior details that are deemed worth saving." Combining the two, HKT Architects have made City Hall green while preserving its history. "...HKT rebuilt the entire interior with skylights and glass office walls so sunlight can reach deep inside. Energy-efficient systems include hidden solar panels on the roof, a ground source heat pump, and auto-shutoff lights. The building has low-emitting paints, adhesives, and carpets; the maple and cherry in interior spaces came from a forest where sustainable practices are used; and 80 percent of the construction waste was recycled. The project is shooting for a gold and minimally a silver rating under the US Green Building Council's Leadership in Energy and Environmental Design certification system."
