Before the days of air conditioning, Wilmington’s many porches, projecting roofs, awnings and operable shutters provided shelter from the summer heat. Commercial buildings used store windows, light wells and skylights to introduce light into buildings. Open air markets were common, and tall trees, shrubs and other natural elements provided shade and protection from the sun. The condition of these existing features should be considered before retro fi tting historic buildings for energy conservation. Suggested Repair and Maintenance Make sure all windows, doors, awnings , operable shutters and other features contributing to natural ventilation are in working order. Replace damaged shade trees if needed, then proceed with the normal ways to conserve energy which include the installation of storm windows and doors, weatherstripping , and the addition of mechanical systems. In the process, care must be taken to retain the historic character of the building. Install insulating material on the inside of masonry walls to increase energy ef fi ciency without disturbing interior character de fi ning details. Insulation should also be installed in attics, unheated cellars and crawl spaces. Solar Panel 515 South 2nd Street Source: City of Wilmington 3.9 Utilities and Energy Retro fi t
