Position Statements
Fostering Renewable Energy Development and Historic Preservation at All Scales
The National Trust recognizes that changes in our energy production and consumption must be made at all scales – from historic buildings to Main Streets to vast public lands – as an element of sustainable development. At the same time, we are working to protect our nation’s historic places by advocating for the appropriate siting of renewable energy infrastructure.
Weatherizing Existing Windows
It is frequently assumed that window replacement is required to substantially improve the energy efficiency of homes, but existing windows can often be weatherized to achieve efficiencies comparable to new windows.
Deconstruction
The National Trust for Historic Preservation supports the practice of deconstruction of older and historic buildings, but only as a last resort when the continued use or adaptive use of the older or historic building is not possible.
