Vermont Law School’s 110 year old Debevoise Hall serves as an historic landmark in South Royalton’s village center. While maintaining the building’s historic exterior integrity, we were challenged by Vermont Law School to make certain that the structure’s renovation incorporated a high level of sustainable initiatives. Some of the environmental strategies used include re-using the building and recycling the materials generated during the construction of the project, improving the thermal efficiency of the existing building envelope, maximizing daylighting and efficient electric lighting and controls, high efficiency heating, ventilating and air conditioning systems, composting toilets and other strategies to minimize waste leaving the building and water use and commissioning the building to ensure optimal building operation.
