In historic preservation, sustainable preservation is the idea that preservation has tangible ecological benefits, on the basis that the most sustainable building is one that is already built. Historic buildings can have advantages over new construction with their often central location, historic building materials, and unique characteristics of craftsmanship. Arguing for these connections is at least partially an outgrowth of the green building movement with its emphasis on new construction. Sustainable preservation borrows many of the same principles of sustainable architecture, though is unique by focusing on older buildings versus new construction. The term "sustainable preservation" is also utilized to refer to the preservation of global heritage, archaeological and historic sites through the creation of economically sustainable businesses which support such preservation, such as the Sustainable Preservation Initiative and the Global Heritage Fund.
