Hello,

When entering material areas on the façade, the unit volume of solid-bodied materials such as thermal insulation, plaster, and pumice can be easily calculated by the system using thickness and surface area inputs. However, the construction system — which consists of components like angle brackets, screws, and T-profiles — is a perforated/voided structure, as these elements are placed at certain intervals within the cavity.

Therefore, I would like to inquire whether the software is capable of automatically performing such calculations for these types of components when the material area is provided.

Best regards.

Hi Ikranur!

Whether you need to calculate material quantities yourself hinges on the product’s profile and how its Environmental Product Declaration (EPD) is presented.

For some materials, like studs, quantities might already be conveniently calculated for a standard area, such as one square meter. However, even for these seemingly straightforward products, an EPD might still require you to perform your own quantity calculations.

Therefore, examining the EPD of each product you’re considering is a smart move. This will reveal whether you can use pre-calculated quantities (like # of screws or studs per square meter or wall thickness) or if you’ll need to work with total quantities, such as the total weight of screws or studs required.

  • For instance, the EPD for screws is often calculated per kilogram. In such cases, you would need to determine the total quantity of screws required for your specific application. You can see an example here: Sign in to One Click LCA

  • Conversely, an EPD for a steel stud profile might be pre-calculated per square meter. Here, your task would be to calculate the total area the studs will cover, rather than counting individual studs. You can find an example of this here: Sign in to One Click LCA

Hope this helps!
