Historic Preservation = Sustainability

Older and historic buildings comprise more than half of the existing buildings in the United States. Retention and adaptive reuse of these buildings preserves the materials, embodied energy, and human capital already expended in their construction. The reuse of historic buildings is one of the most beneficial “green” practices, and stresses the importance and value of historic preservation in the overall promotion of sustainability.

The State Historic Preservation Office believes energy and resource conservation in historic buildings can be accomplished responsibly without compromising the qualities that define their intrinsic historic character.
