The GREET team of Systems Assessment Center at Argonne National Laboratory is pleased to announce release of a new GREET Building LCA Module.

The 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.

• Fixed issues related to building material LCA modeling caused by inconsistent naming conventions
• Restructured energy use intensity data to greatly improve data loading and calculation efficiency of building operation modeling
• Enhanced preview of data entries at the Graphical User Interface for whole building LCA

• Building Component Analysis Module allows users to conduct detailed life cycle analyses of individual building materials, building components, and building technologies with a flexible system boundary and functional unit
• Whole Building Analysis Module allows users to compile a Bill of Materials and energy usage to calculate embodied and operational emissions and energy use
• Whole Building Analysis Module interacts with the Building Component Analysis Module and enables holistic assessment of embodied and operational impacts of alternative material choices and building designs
• Graphical User Interfaces for step-to-step data entry, modeling, and visualization of LCA results
• Consistent and transparent embodied greenhouse gas (GHG) emissions and energy use impacts can be compared among building materials, building technologies, and whole buildings/building designs
• Whole building modeling enables holistic analysis of potential trade-offs between embodied and operational GHG emissions and energy consumption for whole buildings and alternative building designs
• Integration with GREET 1 and GREET 2 provides reliable, updated data for common process fuels, electricity, materials, and transportation modalities for LCA modeling of building materials and whole buildings
• Transparent design allows users to view, modify, and expand background databases used for transparent and up-to-date material-level and whole building LCA
