Adjusted CO2-threshold for constructions with special conditions according to BR18

Hi community

In the danish LCA method in BR18, it is allowed to exceed the national CO2-threshold, if your building has special conditions, such as bad geotechnical properties of the ground, high level of safety (CC3 or higher), etc.

The conditions are explained here https://www.bygningsreglementet.dk/Bilag/B2/Bilag_2/Tabel_9#f00f6d89-6367-439e-baff-981c21725ab7 or here https://www.bygningsreglementet.dk/tekniske-bestemmelser/11/brv/version-2-bygningers-klimapaavirkning/kap-2_4/

Is it possible to adjust the CO2-threshold in RTLCA after correcting for materials/constructions effected by special conditions?

Hi @MarkLabrosse

We don’t have a specific feature developed for this, but you can use the custom calculationtype and adjust the threshold as needed.

I guess we could make a custom excel-spreadsheet that does this manually for now, but doing it manually would be rather time consuming and would make the Emissions Overview graph in the Insights-view obsolete.

I would say that adding this feature is a fairly high priority to make RTLCA compliant with BR18 :thinking: Don’t know, if I’m the only one that feels so :sweat_smile:
