CHAPTER 1 - J( BUILDINGS RESPOND TO EXPOSURE, NOT JUST TIME Age certainly matters, but exposure often matters more. Consider two homes constructed during the same year using identical building materials and identical paint systems. Morning moisture lingers and rainfall is more frequent. Biological growth occurs more rapidly. Surfaces stay wet longer. increasing the risk of mildew. algae, and wood decay. Result: Faster biological growth and moisture-related wear. ' I, -Q- Greater sunlight exposure and lower rainfall. , I' -~@$_- Increased ultraviolet radiation causes faster fading ' , ' and oxidation. _;!) Potentially higher salt exposure depending on location ~ v and prevailing winds. 1Jll' Result: More fading, oxidation, and surface breakdown. Although both homes share the same chronological age, their environmental histories are entirely different-and so are their maintenance needs. MANY FACTORS INFLUENCE EXPOSURE Several variables determine how any given property will age over time. These factors interact with the five primary climate drivers discussed on the next page. -'d· Proximity to ~ Elevation ~ Wind Direction .,.
