Historic properties can be made more sustainable, energy-efficient, and resilient, improving their performance and use while also preserving their historic character. Doing so not only improves their efficiency and livability but helps to ensure their long-term preservation as well. 
 
The NPS has been providing guidance and technical preservation information on these issues in relation to the Secretary of the Interior's Standards for the Treatment of Historic Properties for decades since producing one of its first Preservation Briefs on the subject of energy efficiency in 1978. 
 
Current NPS guidance and information are collected and presented in a new webpage for easy access to further explore these topics.
