On the Duurzaamheid (Sustainability) tab of a project you see how much timber and sheet material it contains, how much CO2 is stored in it and what the indicative MPG contribution is. The MPG is the Dutch environmental performance score for buildings. Below that is the material passport for circular construction. You see the tab with the Houtvoorraad & Materiaalplanning (Timber stock & material planning) add-on (€139 per month) and the right to view materials.
The CO2 and MPG overview
Beamcore calculates with the final timber list and sheet list of the project, otherwise with the newest provisional one. Per material type you see:
- the volume and the mass;
- the biogenic CO2 stored in the timber;
- the shadow costs, also per year over the service life.
Exporteren naar PDF (Export to PDF) downloads the overview, for example for a tender. All values are indicative. It is an MPG contribution of the materials, not an official MPG per m² of gross floor area. For a tender, preferably use the factors from your supplier's environmental product declaration (EPD) or the Dutch Nationale Milieudatabase. If the shadow costs of a material are unknown, the total is unknown; Beamcore never fills in 0.
Adjusting the factors
- Go to Bedrijf → Duurzaamheidsfactoren (Company → Sustainability factors).
- Adjust the factors per material type and check the service life (75 years by default).
- Click Opslaan (Save). Standaardwaarden herstellen (Restore default values) takes you back to the Beamcore reference values.
A material is recognised by its name. If a name is not recognised, Beamcore uses a general factor and says so.
The material passport
The block Materialenpaspoort (Material passport) is below the CO2 overview. If the project has a processed IFC model on the Productie (Production) tab, it shows per element per material the quantity, the volume, the area (for sheets), the weight and the stored CO2. Without an IFC model everything comes from the timber and sheet list, as one line without elements.
Supplier and batch come from the materials you linked to the project under Materiaalcertificaten (Material certificates). If it is not clear which link belongs to a line, the supplier stays empty: Beamcore does not guess.
You download the passport as Madaster (Excel), Madaster (CSV) or IFC-propertysets (CSV) (IFC property sets, CSV). You put that last file into the model with an IFC program. The import file has not been checked against an official Madaster template. The button Naar Madaster sturen (Send to Madaster) is still disabled: the direct link requires an API key from Madaster. Until then, you import the file into Madaster yourself.
Insulation, membranes and fasteners are not in the IFC model and therefore not in the passport.
