Step-by-Step
The thresholds are project-specific, not fixed table values. Per zone, the formula applies:
Base value B × zone area A ÷ EBF
The rows (component groups, building services, uses) are summed to the variant total and compared with the LCA result.
On the Thresholds page, you can switch between Minergie-ECO, Minergie, and SNBS; the columns "Formula" and "Evaluated formula" make the derivation traceable.
After changes to zones or areas, first click "Recalculate" on the LCA page.
