STANDARDS AND GUIDELINES FOR SUSTAINABILITY INTRODUCTION Design and construction of historic structures maximized the use of natural resources such as light and ventilation. This chapter will explore old and new techniques to assist you in maintaining your home and provide additional energy efficient options. These techniques and options will allow your home to operate efficiently while maintaining its character defining features. Proof of an En- ergy Audit from the City of San Marcos' Conservation Coordinator is recommended prior to undertaking the following techniques. The least visible improvements shall be undertaken first. The more visible improvements should only be considered once the least visible improvements have been completed. MAINTAINING WOOD WINDOWS STORM DOORS AND WINDOWS SHUTTERS SCREEN DOORS AND WINDOWS COOL ROOFS SOLAR TECHNOLOGY WOOD WINDOWS— MAINTENANCE AND EFFICIENCY The US Department Of Energy estimates that windows account for roughly io% of a structure's air loss. Three basic steps can be taken to reduce the amount of air loss through the window unit; maintenance and the installation of low –e film and storm windows. From #3 NPS rvation Brief There energy loss occurs. MAINTENANCE, WEATHER STRIPPING AND CAULKING Maintaining windows on a regular basis to ensure that they operate properly will significantly reduce the amount of air loss. This includes replacing rotten wood, painting, and adding weather stripping and caulk. Weather stripping should be used between the movable parts of a window. It can easily become ripped, torn, loose, bent or otherwise damaged so follow the manufacturers instructions for installation and routinely inspect and replace if needed. Caulk and other sealants can be used on the exterior of your building where different materials meet or where expansion and constriction occur. REMINDER: All exterior work visible from the right -of -way requiring a building permit requires a Certificate of Appropriateness and must conform with all of City of San Marcos ordinances. It is helpful when using these guidelines to be familiar with your architectural style.
