The ACHP promotes sustainable and resilient communities where historic properties are used as assets for promoting energy efficiency and community livability, and are protected from climate impacts.

The ACHP is working to help ensure that the federal government addresses historic properties as it creates and implements sustainability and climate resilience policies and programs. Below under "Related Resources" you will find a collection of links to information on the importance of historic properties to the national conversation on sustainability and climate resilience. Gateway sites on these topics include:

Communities throughout the country are threatened by increasing climate impacts, such as storm damage, flooding, coastal erosion, drought and associated wildfires, melting permafrost, and changing temperature patterns. Climate-related destruction undermines sense of place and community identity, in part through damage to historic properties. Communities are seeking ways to adapt and be more resilient to climate impacts, including impacts to historic properties. Good introductions to this topic include:

When it comes to historic buildings, in most cases the “greenest” building is the one already built. Preserving historic buildings almost always offers environmental and energy savings over demolition and new construction. Reinvestment in historic districts and communities also promotes reuse of existing infrastructure and supports areas that generally are walkable and have good transit access options. The result? Energy savings and enhanced community livability. Supporting cost-benefit analyses include:


In resilient and sustainable communities, historic properties contribute to energy efficiency and community livability, and are protected from climate impacts.
