Global Warming Potential – LCA Measure Graph by Life Cycle Stage
NOTE:
This report was retired as a LCA Measure in version 5.0
This graph displays the Global Warming Potential results by life cycle stages. Each life cycle stage is further broken down into Global Warming Potential contributions of materials, transportation and annual operating energy. A total Global Warming Potential effect is also provided for the project desegregated on the basis of sub-group contribution over the expected life of the project, but only includes one year of operating energy.
The Athena Sustainable Materials Institute (ASMI) is set to publish the first North American Environmental Building Declaration (EBD) according to European Committee for Standardization's standard dealing with sustainability of building construction, EN 15804/15978, and in the interest of standardization across building product categories, we have incorporated EN 15804/15978 into the Impact Estimator's results starting wiht v4.2.0208 (April 2013). This means redefining our life cycle stage tables and graphs. It is mostly a change in nomenclature and a re-arrangement of our previous life cycle stage columns, the total results do not change. One change is that some results from the Product/Material stage (previously Manufacturing/Material) have been shifted to the Construction Process/Construction Installation Process stage. Previously, all calculated materials, including the construction waste allowances were reported in the Manufacturing stage, but now the calculated material totals will be reported in the Product/Material stage and the construction waste allowances will be reported in the Construction Process/Construction Installation Process stage.
EN 15804/15978 requires the reporting of a specific set of environmental indicators according to a modular format of the life cycle of building products or constructed works including four stages, (Product, Construction Process, Use, End of Life) and each stage is comprised of "information modules", the modules compare roughly to our previous Material and Transportation columns and are defined below (the corresponding EN15804/15978 module appears in brackets).
Life Cycle Stage Definitions:
- Product:
Construction Process:
Replacement:
Operational Energy:
End of Life:
