The Secretary of the Interior's Standards for the Treatment of Historic Properties, as amended in 1995

GUIDELINES ON SUSTAINABILITY FOR REHABILITATING HISTORIC BUILDINGS

Published in 2011, the Guidelines on Sustainability are the first set of official guidelines on how to make changes to improve energy efficiency and preserve the character of historic buildings. The Guidelines are an important addition to current discussions about sustainability and achieving greater energy efficiency, which have focused primarily on new buildings to date.

The Guidelines on Sustainability stress the inherent sustainability of historic buildings and offer specific guidance on recommended rehabilitation treatments and not recommended treatments, which could negatively impact a buildings historic character. Illustrations of both types of treatments are included. The Guidelines are designed to assist building owners in planning rehabilitation projects that will meet the Standards for Rehabilitation.
