This Concept Map, created with IHMC CmapTools, has information related to: Roof, SOLAR REFLECTION High Solar Reflectance Roofing: results in ≈10°C differance between surface & ambient temperature Light coloured roof, ROOF ???? SOLAR SHADING, reflects unwanted heat to reduce heat transmission into building alternative Cover using deciduous/creeper plant. Evaporation from leaves lower temperature, THERMAL INSULATION Polystyrene a better insulator for tropical roof compared to mineral wool, ROOF ???? SOLAR REFLECTION, SOLAR SHADING Shading Devices control amount of solar radiation into building to lower cooling load & improve indoor thermal comfort, Light coloured roof reflects unwanted heat to reduce heat transmission into building, SOLAR SHADING Flat roof Concrete : cracking due to expansion and contraction, THERMAL INSULATION Mineral Wool Not adapted to tropical climate Lose thermal properties when absorb ambient humidity, SOLAR SHADING Shading Devices eg: Deep overhangs Window shading device, ROOF ???? THERMAL INSULATION, SOLAR SHADING Metal roofs Effective heat conductors Corrosion by contact with humidity, SO2 in atmosphere, SOLAR SHADING Big eaves & HighPitched Roof plenty of shade around building & protect outer walls from weather elements
