(A) Historic structures were built to take advantage of natural heating and cooling with high ceilings for summer heat and large windows to let in natural light. Many times a simple fine tuning of existing systems and components is all that is needed to make a historic building energy efficient at a fraction of the cost of an entire retrofit.
(B) Listed below are some hints on making the building environmentally friendly and saving money in the long and short term.
(1) Use awnings and canopies. Historically, these were used to provide shade during the summer months. Used in conjunction with open windows and high ceilings, interiors will stay cooler during the summer months. With central air, these items will keep the cooling costs down.
(2) Use caulking and weather-stripping. These will improve efficiency of the doors and the windows. Air will enter through cracks in trim, windowsills and door jambs. Be sure to use materials that will not detract from the appearance of the building.
(3) Use storm windows. Storm windows also help reduce air infiltration at a fraction of the cost of replacing the entire window. Mount the storm window on the interior to preserve the original appearance of the exterior. Add weep holes in order to prevent any moisture condensation. Exterior mounting of storms is another option. When this is done, match the existing size and configuration of the window itself.
(4) Use insulation. Insulate the attic area of the building. Heat loss through the roof is a major cost and can be prevented with a minimal investment. Consult an insulation professional to determine the best type for the situation. Be sure to ventilate the space properly.
