Sustainability and Energy Efficiency
The idea of sustainability is an inherent principle of historic preservation. From the beginning, historic preservation has been about retaining well-designed, well-constructed resources for the present and the future. Increasingly, historic buildings are being targeted for modern weatherization improvements that are often costly and unnecessary. Research has shown that historic buildings can be just as energy efficient as new buildings without destroying their historic character.
