The GREET team of Systems Assessment Center at Argonne National Laboratory is pleased to announce release of a new R&D GREET Building LCA Module.
The R&D GREET Building LCA Module is designed to conduct and compare detailed and transparent LCA of building materials/components/technologies, as well as whole buildings and building designs.
October 11, 2022
Major expansions and updates in R&D GREET Building LCA Module 2022:
- The Building Component Analysis module has been augmented to support time series modeling and assess technology advancement over time
- The Whole Building Analysis Module has been augmented to enable sensitivity analysis. A Bill of Materials for a building, whence run through the initial LCA, can be set up for sensitivity analysis. The quantity, material type, loss factor, replacement period, and adjustment factor can be set up for each individual material, and the changes in emissions analyzed for each separate factor
- The Whole Building Analysis module has been augmented to allow for disaggregated life cycle results. Life Cycle Analysis results can be aggregated to the system boundary or disaggregated and calculated at each life cycle stage
- The LCProfiles database has been expanded into two worksheets to handle the disaggregated whole building analysis, as well as the time series analysis functions
- The Data Gaps feature of the Building Component Analysis module has been improved to allow the user to view and resolve the data gaps of the material loaded into the module, in addition to being able to view data gaps for all materials. The user can additionally see what years of data are available for a given material in a table on the BCA Dashboard
- Forward and backwards propagating LCA have been added to BC Analysis. Backwards Propagating LCA will recursively run LCA on all subcomponents of a material before running LCA on the material itself. Forward LCA will allow the user to select a group of materials that use the selected building material as a subcomponent, and additionally run LCA on those selected materials, to propagate the change in a material’s life cycle profile upwards
- A “Material Updates” list has been added to BC Analysis. This list keeps track of what materials are updated, and marks which materials also need to be updated due to using the original material as a subcomponent. This list is also connected with the forward propagating LCA feature, allowing the user to quickly update any materials that need to be re-run due to subcomponent updates
