To a visitor, nothing about the 9,000 square foot, single story building at 391 Boston Post Road, identifies it as green, other than perhaps the warmth of the old brick, the noticeably pleasant interior air quality, natural lighting, and overall cleanliness of the environment. Here’s some of what qualifies it for LEED certification:

• Demolition. Value of the steel helped offset the asbestos removal and demolition. The Cherry Hill Construction Company methodically razed the building, separating its materials into piles of steel, concrete, wood, metal, glass, and asphalt for sale to recycling companies.

• Construction. Pace Setter Construction recommended a Butler building, but as it turned out, the Butler Manufacturing Company is among the many major suppliers who have been tracking LEED requirements. “The building system was not only architecturally great, it used all recycled steel, with deep, substantial foundations and a Cool Roof system,” says Robert Kravitz of Go Green, LLC. The steel, the roof, plus the use of recovered masonry brick, exceed the 80% recycled materials LEED requirements.

• Windows. Low E thermal windows block UV rays, let in 93% of natural light, and reduce lighting costs.

• Heating and cooling. The HVAC system is the single most important component affecting energy efficiency and costs and uses an environmentally safe refrigerant.
