Thornton Tomasetti, acquired by Thornton Tomasetti in 2012, provided LEED consulting services for a new 27,300-square-foot maintenance and transportation center that is phase one of a three-phased enhancement of visitor facilities at Acadia National Park. Phases two and three include an intermodal bus station with parking and a National Park Visitor’s Center aimed at reducing vehicle traffic on nearby Mount Desert Island.
The firm’s role was LEED administrator, conducting a sustainability charette, providing peer review of energy modeling, coordinating LEED compliance and administering final submittal of LEED documentation. Project challenges such as storm water drainage issues, construction erosion and sedimentation control required particular attention.
The bus maintenance facility is critical to the operation of propane-powered buses that will reduce traffic by an estimated 10 million vehicles per year. A specially designed bus wash system reuses 90% of water used and significantly reduces demand. The project demonstrates a 38.3% improvement in building energy performance, taking advantage of strategies including an efficient thermal envelope and glazing, high-efficiency HVAC systems, extensive daylighting throughout and reduced interior lighting power density. Local materials and those with recycled content were used whenever possible and more than 70% of construction waste was diverted from landfills.
