Statement on Sustainability


Historic preservation should be an important component of any effort to promote sustainable development. The conservation and improvement of our existing built resources, including re-use of historic and older buildings, greening the existing building stock, and reinvestment in older and historic communities, is crucial to combating climate change.  Perservation New Jersey is advocating for sustainabilty and energy efficiency policies that make historic properties "greener" without risking their character.  In the rush to address climate change through development, it is often forgotten that "the greenest building is the one already built."

Look for new tips, links and recommendations in this space to help promote Preservation = Sustainability.


Guiding Principles:

REUSE existing buildings: Use what you have. The continued use of our existing buildings reduces the amount of demolition and construction waste deposited in landfills, lessens unnecessary demand for energy and other natural resources and conserves embodied energy (the amount of energy originally expended to create extant structures).

REINVEST in our older and historic communities: Older and historic communities tend to be centrally located, dense, walkable, and are often mass-transit accessible – qualities celebrated and promoted by Smart Growth advocates. Reinvestment in existing communities also preserves the energy embedded in infrastructure, such as roads, water and sewer lines.

RETROFIT our existing building stock: Many historic and older buildings are remarkably energy efficient because of their site sensitivity, quality of construction, and use of passive heating and cooling, while other buildings require improvements to reduce their environmental footprint. Historic buildings can go green without compromising historic character.
