Historic properties are important reflections of the past and contribute to the uniqueness of our communities. Old buildings are well-built but often leave occupants feeling too hot in the summer and too cold in the winter.  The good news is that by applying building science principles combined with historic preservation standards, it is possible to make them more comfortable, reduce the amount of maintenance required to ensure their survival for generations to come.
