Smart Growth and Preservation of Existing and Historic Buildings
On this page:
The renovation of a historic property is often a starting point and anchor for the redevelopment of a block, street, or district, and an important part of a smart growth approach.
- A historic building or district can be a tangible symbol of a community's interest in honoring its heritage, valuing its character and sense of place, getting the most out of prior investments in infrastructure and development, and encouraging growth in already-developed areas.
- Rehabilitating historic properties can be a critical part of promoting energy efficiency by preserving the energy already represented by existing buildings (known as "embodied energy"), rather than expending additional energy for new construction. A new, green, energy-efficient office building that includes as much as 40 percent recycled materials would nevertheless take approximately 65 years to recover the energy lost in demolishing a comparable existing building.1
- Repurposing old buildings—particularly those that are vacant—reduces the need for construction of new buildings and the consumption of land, energy, materials, and financial resources that they require.
Current codes and many green building standards do not always provide a clear path forward on how to redevelop and revitalize historic and other existing buildings to achieve sustainable outcomes. For example, replacing windows and doors—key elements for an energy-efficient building envelope—often poses a challenge to preserving the historic integrity of older buildings.
Communities that seek to both increase their sustainable investments and protect their historic assets must resolve standards and policies that can at times conflict and could make some projects financially infeasible. Yet the value in overcoming these obstacles is clear—not only for the energy benefits they offer, but also for broader economic, cultural, and land use preservation advantages.
This page lists resources for communities that want to invest in and rehabilitate existing buildings, regardless of whether the buildings qualify for consideration and review under formal historic preservation provisions (such as Section 106 review triggered by federal action). These resources can help inform a community's approach to smart growth through historic preservation and identify ways to overcome challenges.
