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. The NPS has been providing guidance and technical preservation information on these issues for decades.
Visit their new Sustainability, Energy Efficiency, Resilience & Historic Buildings Webpage for links to current NPS guidance and information and for easy access to further explore these topics.
