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

• Find standard terms
• and definitions
• Export to XML file

• 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

• Semantically rich
• data that can integrate
• CO2 data at a detailed
• level and from many
• sources
