How to model a building product installed later in the process
Purpose
Section titled “Purpose”Model a building product that’s only installed a number of years into the assessment period, not at the project’s start.
Prerequisites
Section titled “Prerequisites”The building product has been added to a construction in the building model.
- Find the building product in the building model tree.
- Enter offset start as a number of years, not a checkbox, a number.
What happens in the calculation
Section titled “What happens in the calculation”- A1-A3 is reclassified to B4A1to3 in the year
start + N. - If that year falls after the end of the assessment period, the building product contributes nothing, silently. There’s no warning in the UI that the contribution was dropped.
Result
Section titled “Result”The building product only counts in the calculation from the specified year, as a replacement rather than an original part of the building.
Trap: a building product with an offset start far in the future can end up contributing zero to the result with no visible warning. Always check that the offset year falls within the assessment period if the building product is meant to count.
