The Illustrated Guidelines on Sustainability begins with an overview focusing on the fact that historic buildings are themselves often inherently sustainable and that this should be used to advantage in any proposal to upgrade them. These guidelines offer specific guidance on how to make historic buildings more sustainable in a manner that will preserve their historic character and that will meet The Secretary of the Interior’s Standards for Rehabilitation.
The Illustrated Guidelines on Sustainability for Rehabilitating Historic Buildings replaces the chapter on ‘Energy Conservation’ in the Illustrated Guidelines for Rehabilitating Historic Buildings published in 1992.
