Total house building CO 2 emissions defined using ISO 15926 reference data 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. Location Length of life LCA reference data • emissions for materials • emissions for transport • emissions for energy from LCA Info Hub Total CO 2 emissions from construction for each year of use

Scope of ISO 15926 house demo for CO 2 emissions • Design of 180 m 2 house • Designer can choose between – – Wooden frame and wooden walls Steel frame and concrete walls Wood frame and brick walls • Unit of function, CO 2 release per m 2 of house • Raw material production, final products fabrication, transportation and removal to be considered

Scope of LCA Example Raw Material Transport Fabricate Transport Product Dispose

System design ISO 15926 object model for house EU LCA Info Hub selection of relevant LCA reference data edit merged data as RDF Design of a house Location Length of life export of model with relevant reference data Bill of materials Total CO 2 emissions from construction for each year of use LCA reference data EXCEL

Data Flow, Design of House based on LCA of CO 2 release Reference Data System browser ISO 15526 RDL • Find standard terms and definitions • Export to XML file RDF Schema LCA of House • Semantically rich data that can integrate CO 2 data at a detailed level and from many sources Excel macro’s Manual input of CO 2 emissions Design modifications EU LCA data base of CO 2 emissions • Extract CO 2 data on a unit basis • Manual CO 2 input on a unit basis for data not found in EU data base • Input material quantities • Input transport distances • Get CO 2 release

Depuis test case: Data flow house construction Mapping table RDL - LCA terms RDL ISO 15926 -4 • Terms and definitions • Hierarchy • Properties • UOM Application • Retrieve information • Calculations house • Optimisation CO 2 • Reporting Barbie / Lexicon • Properties – product • Brick – CO 2 • Steel – CO 2 • Wood – CO 2 GUI • Input parameters (sizes) • Selecting material (bricks/ concrete, etc. ) • Desired constraints • Interactive dialogue LCA Info Hub • Terms and Definitions • Hierarchy • CO 2 per material used • Build up of emission

Depuis test case: Exchange scheme house construction EXCEL ISO 15926 -4 • Excel sheets • OWL file POSCCaesar RDS • Extension construction • OWL file XML OWL X-Query XSLT Application • Excel • Calculations • Macros • Reports SPARQL OWL RDF LCA Info Hub (website) • XML file • uri missing RDF GUI • Excel • Import • SPARQL • X-QUERY • XSLT - Use common definitions - LCA Info.
