This is a space for helping you use and understand Building Transparency's suite of tools, including:
Due to the ever-changing nature of the tools, this User Guide is continually a work in progress.
Upfront vs. Whole Life
Upfront assessments only account for life cycle stages that can be measured upfront. Whole Life assessments also account for future use-stage and end-of-life aspects anticipated based on current trends.
Carbon vs. Multiple Impacts
Carbon assessments consist of tracking only the following impact category:
- Global warming potential (GWP) measured in kgCO2e
Complete Life Cycle Assessment usually also considers other impact categories, such as, but not limited to, the following:
- Acidification potential (AP)
- Eutrophication potential (EP)
- Ozone depletion potential (ODP)
- Smog potential (SP)
Life Cycle Assessments also usually report non-impact categories, such as depletion of resources and generation of waste.
