SOSE Notes- Zinalume – Sustainable Roofing ZINCALUME steel for Roofing Product Description and Features Roof sheeting made from ZINCALUME® steel is available in a range of profiles. The zinc/aluminium alloy coating on ZINCALUME® steel imparts corrosion resistance of up to four times the life of galvanised steel. Zinculume is the ideal roofing for a eco freiendly house. * Durable and strong * One of the most thermally efficient roofing materials available today * Superior corrosion resistance * Attractive * Available from an extensive network of suppliers * A deterrent against intruders * Excellent resistance to impact from hail * Excellent flexibility in design, can be curved, for truly individual designs * Flexibility of design allows for both traditional straight roof sheeting as well as innovative curved roofing designs * Easy maintenance * Weather tight and secure when installed to manufacturer's specifications. Themal Mass – Rising temperatures: Solution: Thermal Mass. What is it? Thermal mass is the ability of a material to absorb and store heat energy. Materials such as concrete, bricks and tiles have a high density. Using materials that have lightweight such as timber have a low thermal mass. This means that through the hot days throughout the year, they absorb the heat and then at night time when it gets colder the heat is released, this is going to make a major difference to the temperature of your house and your electricity bills because you won’t need to use the air-con/ heater as much now. So for as many parts of your house as you can try to use concrete, this could easily be used for the floor and walls. Then this house will have a lower temperature on average. Street Orientation Orientation is the positioning of a building in relation to seasonal variations in the sun’s path as well as prevailing wind patterns. Good orientation can increase the energy efficiency of your home, making it more comfortable to live in and cheaper to run. ...read more.

but allows for flow off of rainwater into gutters and pipes. * Small vents on the southern side of the house ideal for the cool breezes to filter through house and large clerestory windows situated on the northern side to allow hot air to rise and flow out of house. * Clerestory windows span around in row near ceilings to provide method of cross ventilation and allow rising hot air to flow out. Also provide natural light in summers without requirement of large windows that bring heat in. * All windows to be of super efficient make that feature soft-coat low-E double- glazed coatings, inert gas in a vacuum-sealed air gap, warm edge spacers and more efficient frame technology. Block over 70% of solar heat gain and provide R-3 thermal resistance- minimizing penetration of heat in summer but maximizing heat absorption in winter. Solution 2: Thermal Mass Insulation (Not to be used in essay) * Thermal mass is the ability of a material to absorb and store heat energy. * Materials such as concrete, bricks and tiles have a high density. * Using materials that have lightweight such as timber have a low thermal mass. This means that through the hot days throughout the year, they absorb the heat and then at nighttime when it gets colder the heat is released. * This makes a major difference to the temperature of your house and your electricity bills because you won?t need to use the air-con/ heater as much now. * So for as many parts of your house as you can try to use concrete, this could easily be used for the floor and walls. Then this house will have a lower temperature on average. Solution 3: Green/Zincalume roof with Deciduous Trees and Grape Wines * Deciduous trees (meaning trees that drop all leaves in autumn) and grape vines provide added cooling through the leaf transpiration process. ...read more.
