Building Energy Software Tools DirectoryThe US Dept of Energy created a comprehensive list of resources that calculate the environmental cost of a building project.Sheila Chung. Here's an example of one of the resources listed in this directory: Athena Model - You enter a general description of your building. The model breaks down the selected assemblies comprising a design into their respective products for the purpose of applying the model's life cycle inventory (LCI) databases that contain estimates of the environmental effects per unit of each building product. The inventory data includes natural resource, energy and water inputs to processes as well as emissions to air, water and land for the manufacture, transportation and use of all of the individual building products. www.eere.energy.gov/buildings/toolsdirectory/alphalist.cfm |
