All Measures Table by Life Cycle Stage
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 with 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.
This table displays the LCA Measure results by Life Cycle Stage. Each Life Cycle Stage is further broken down into separate contributions. The total effect for each LCA Measure is also provided for the project over the expected life of the project.
Note that this table can also be viewed in a Condensed format where only the Total Columns of each Life Cyle Stage are shown.
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 (Beyond Building Life is optional) 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).

All Table and Graph reports use a "Report Viewer", that has a common toolbar. Each member of the common toolbar is detailed in the "Report Toolbar" page.
