Life Cycle Assessment

is widely accepted as the best basis for comparing the environmental impact of alternative materials, components and services. In the case of buildings, material manufacturing is the most important contributor of emissions to water and land, including toxic releases. A recent US study found that construction is the sector producing the most CO2 emissions through the manufacture, transport and use of materials. A Canadian study indicates that the embodied energy in office buildings can be equivalent to more than 20 years of operating energy use, and that material selection or other design decisions can significantly reduce embodied energy. LCA is the route to document, understand and reduce such critical environmental effects.

 

The Athena Institute has prepared this report in an effort to provide an indication of the inner workings of the Impact Estimator for Buildings, i.e., what the software does and how it does it. The report illustrates the relationships between building materials, components and assemblies, how they were arrived at and how they are called upon in the software. It also outlines the various life cycle stages the software supports and the methods used to derive a complete building environmental life cycle inventory and impact assessment profile. The software’s embedded databases are also explained, highlighting their use within the tool.

NOTE: The "Inner Workings" transparency document for the Impact Estimator for Buildings Version 4 will be available soon.
