  1. defined using ISO 15926 reference data from LCA Info Hub Total house building CO2 emissions • Design of a house • civil/structural systems • wall areas • room volumes • wall materials • foundations • framework • access roads • mechanical systems • heating/cooling • electricity generation • Bill of materials • civil/structural materials • masses and volumes of timber, plasterboard, concrete, brick, etc.. • mechanical materials • masses and lengths of piping, cable etc. • mechanical devices • boilers, heat pumps, tanks, etc. Total CO2 emissions from construction for each year of use Location Length of life • LCA reference data • emissions for materials • emissions for transport • emissions for energy

  2. House usage CO2 emissions • Design of a house • civil/structural systems • wall areas • room volumes • wall materials • foundations • framework • access roads • mechanical systems • heating/cooling • electricity generation • Energy flows • heat loss from walls • inputs • air heating • air cooling • hot water • Local energy sources Total CO2 emissions for year of usage Location Length of life • LCA reference data • emissions for materials • emissions for transport • emissions for energy

  3. Scope of ISO 15926 house demo for CO2 emissions • Design of a house • civil/structural systems • wall areas • room volumes • wall materials • foundations • framework • access roads • mechanical systems • heating/cooling • electricity generation • Bill of materials • civil/structural materials • masses and volumes of timber, plasterboard, concrete, brick, etc.. • mechanical materials • masses and lengths of piping, cable etc. • mechanical devices • boilers, heat pumps, tanks, etc. Total CO2 emissions from construction for each year of use Location Length of life • LCA reference data • emissions for materials • emissions for transport • emissions for energy

  4. Scope of ISO 15926 house demo for CO2 emissions • Design of 180m2 house • Designer can choose between • Wooden frame and wooden walls • Steel frame and wooden walls • Steel frame and concrete walls • Wood frame and brick walls • Unit of function, CO2 release per m2 of house • Raw material production, final products fabrication, transportation and removal to be considered

  5. Scope of LSA Example Raw Material Transport Fabricate Transport Product Dispose

  6. Conceptual Model, Design of House based on LCA of CO2 release Manual CO2 unit additions Reference Data System browser Excel macro’s EU LCA data base of CO2 emissions ISO 15526 RDL RDF Schema LCA of House Design modifications • Find standard terms • and definitions • Export to XML file • Semantically rich • data that can integrate • CO2 data at a detailed • level and from many • sources • Input material quantities • Input transport distances • Get CO2 release • Extract CO2 data on a • unit basis • Manual CO2 input on a • unit basis for data not • found in EU data base

  7. System design ISO 15926 object model for house EU LCA Info Hub export of model with relevant reference data selection of relevant LCA reference data merged data as RDF Bill of materials Design of a house edit Total CO2 emissions from construction for each year of use Location Length of life LCA reference data EXCEL

  8. Data Flow,Design of House based on LCA of CO2 release Reference Data System browser Excel macro’s Manual input of CO2 emissions ISO 15526 RDL RDF Schema LCA of House Design modifications EU LCA data base of CO2 emissions • Find standard terms • and definitions • Export to XML file • Semantically rich • data that can integrate • CO2 data at a detailed • level and from many • sources • Input material quantities • Input transport distances • Get CO2 release • Extract CO2 data on a • unit basis • Manual CO2 input on a • unit basis for data not • found in EU data base
