TheLEED®CanadaforNewConstruction2009ratingsystem[Ref.3]isbasedontheU.S.version,LEED2009.SomeofthemostnotabledifferencesforbuildingproductsarethatLEED®Canadaincludesacreditforutilizingdurablematerials(RegionalPrioritycreditDurableBuilding),recognizesdifferencesinmethodoftransportforbuildingproducts(MaterialsandResourcescreditRegionalMaterials),andallowsforaspecificrecycledcontentcalculationforproductsutilizingcementreplacements(supplementarycementingmaterials)(MaterialsandResourcesRecycledContent).GoingforwardCanadawillnotdevelopaseparateratingsystembutwilluseLEEDv4,anditisexpectedthatthesedistinctionswilllikelybelost.ThoughLEEDmaybethebestknowngreenbuildingprogram,itisnottheonlyone.TheASHRAE189.1StandardfortheDesignofHigh-PerformanceGreenBuildingsExceptLow-RiseResidentialBuildings(ASHRAE189.1)[Ref.7]isonealternativetotheLEEDratingsystem.ASHRAE189.1issimilartoLEEDwithafewkeydifferences,theprimarybeingthatASHRAE189.1iswritteninmandatory,code-enforceablelanguage.ASHRAE189.1isintendedasaminimumgreenbuildingstandard.UnlikeLEED,designersusingASHRAE189.1haveveryfewchoicesregardingtheprovisionsofthestandard.MostoftheprovisionsofASHRAE189.1arerequired.Asaresult,ASHRAE189.1canbeadoptedbyalocaljurisdictioneitherdirectlyorasacompliancepathwithintheInternationalGreenConstructionCode(IgCCTM)[Ref.2].
