Preservationist is generally understood to mean historic preservationist: one who advocates to preserve architecturally or historically significant buildings, structures, objects or sites from demolition or degradation.
Preservation of historic properties demonstrates long-term vision by preserving irreplaceable cultural resources and promoting sustainability practices by conserving our limited environmental resources. On its most basic level, the practice of historic preservation is the practice of conserving resources. Not only do restoration and redevelopment consume less energy than demolition and new construction, but preservation also recovers the worth of past energy investment.
