Guiding Principles

Guiding Principles for Sustainable Federal Buildings

The Federal Government advances sustainable building principles and practices throughout its portfolio, promulgated through a number of statutory and executive policies which are integrated and utilized by every Federal agency. These sustainable principles and practices have been incorporated into the Guiding Principles for Sustainable Federal Buildings and Associated Instructions (Guiding Principles), to guide agencies in designing, locating, constructing, maintaining, and operating Federal buildings in a sustainable manner that increases efficiency, optimizes performance, eliminates unnecessary use of resources, ensures the health of occupants, protects the environment, generates cost savings, and mitigates risks to assets in a manner, consistent with Agency and Department missions.
