Why so much interest in keeping old windows and doors? Why Go Green?

Go Green - keep old windows and doors

Windows and Doors are the most visible .. and yet most commonly understood and under appreciated parts of older homes or historic homes and buildings. While being beautiful, original historic windows also serve a great purpose – they impart a building's inside and outside character and connection to their surroundings. Not only for ventilation and light, but also function as emergency egress. They offer visible clues to a building's history and aspects of architectural design.
