Selecting the rightEmbodied Carbon per sq Metermaterial for the job can make all the difference. We at the CISC have12CO2 eq per sq meter (home lifetime)conducted an embodied carbon analysis to aid in the decision-making process. 10Traditionalasphaltshinglesareubiquitousinoursuburban8landscape.Thesehydrocarbon-basedslatslayertoprovide protectionfromtheelements.Asphaltshingleshavealifespan6of 15 to 30 years, after which the shingles will have to be removed,4landlled and replaced. Upfront carbon embodiment for a standard asphalt shingle, A1-A3, is 5.26 kg of CO2 eq per sq. metre. The2CANADAS PREMIER STRUCTURAL STEEL 0& FLAT BED TRANSPORT EXPERTS Shingles Steelaverage lifespan of a suburban home is 50-100 years. The average home will require one asphalt shingle roong replacement over a 50-year lifetime conservatively. The lifecycle carbon cost of A1-A3 for 50 years of roong with shingles is therefore 10.52kg of CO2 eq per sq. metre. Steel roong offers a longer lifespan of 50+ years with minimal maintenance. The lifecycle carbon cost of A1-A3 for 50 years of steel roong is 9.4kg of CO2 eq per sq. metre. The choice to use steel roong may result in a 10+-per-cent reduction in upfront embodied carbon. It should also be noted that the phases of carbon embodiment do not end after the product is installed. End-of-life carbon emissions should always be considered where information is available. Asphalt shingles are a large contributor to the waste accumulating in landlls, up to 10 per cent of construction, renovation and demolition waste. Nails used in shingle roong can puncture tires and cause other issues within landlls. These shingles can take up to 300 years to fully decompose, releasing their remainingcarbonintotheatmosphere.Steelroong,ontheother hand, is fully recyclable without any reduction in its material properties.
