With the building physics check you see per wall, floor and roof whether the chosen building system meets the requirements of the project: the Rc value (thermal resistance), the fire resistance in minutes and the sound insulation in dB. You find the page under CRM → Bouwfysica (CRM → Building physics). The check is included in every package. The elements come from the processed IFC model of the project, so via the Productie (Production) or Montage (Assembly) tab.
Setting the requirements
- Choose the project.
- Click Eisen instellen (Set requirements) and choose the use function. A use function for new construction fills in the values from the Dutch building code (BBL).
- Check the Rc requirements for facade, floor and roof and the fire and sound requirement per type of separation. Empty means no requirement.
If you have not set anything, the default requirements for new residential buildings apply: Rc facade 4.7, floor 3.7 and roof 6.3, and for party walls and floors between dwellings 60 minutes and 52 dB. Always check them for your own project.
Per element
The table shows per element the type of separation, the building system, the Rc, the fire resistance, the sound insulation and the result with the reason. Beamcore makes a suggestion:
- the type of separation follows from the element type and the group in the IFC model, for example facade, inner wall, party wall or ground floor;
- the building system is an active system of the same type with the thickness closest to the element.
If the suggestion is not right, click Wijzigen (Edit) next to the element and choose the type of separation and the building system yourself. Your choice stays in place with a new revision of the IFC model.
Reading the result
- Green: the value meets the requirement.
- Orange: the value is unknown, there is no building system, or the building system is only suggested. A suggested system never turns green; confirm your choice first.
- Red: the value is below the requirement.
The tiles at the top filter by result. If the fire resistance or sound insulation of a building system is missing, fill it in via Brand en geluid per bouwsysteem (Fire and sound per building system). The Rc comes from your building system library. PDF-rapport (PDF report) downloads the check.
Beamcore does not calculate an Rc or U-value from the layers and does not replace building physics advice or the review by the building authority. The check compares the values you recorded yourself with the requirements you set.
Who can do what
Employees who may see projects see the check for their projects; customers and contractors do not. Requirements and choices per element can be changed by whoever may edit the project, release elements or manage building systems. Fire and sound per building system are changed by whoever manages building systems.
