City of St. Louis Cultural Resources Office: Section 106 Guidelines

	Section 106 Guidelines: City of St Louis
	Energy Efficiency Energy conservation is a major concern on all projects; however, a significant reduction in energy loss can be achieved with simple measures, which do not alter a building's historic character. Weather stripping, caulking, and the addition of insulation in a non-destructive manner are acceptable procedures under Section 106 review, as is the installation of storm windows and doors. Storm windows on historic buildings may be installed on the interior or exterior of the building. Exterior storms should be made of color-clad material, and should have approximately the same glass area as the windows they cover, and be installed between the existing blind stops, without covering the brickmold. Meeting rails of both storm and window should be at the same height. When covering a round-headed window, the storm should also have a round head. Storm doors on visible facades should preferably be full-light (full glass) or three-quarter-light in order to avoid obscuring the original door. Storm doors with ornamental or security grills are not acceptable. For further information concerning specific requirements for energy conservation and efficiency, please consult Housing Design Standards.
