How to exclude something from the calculation

Purpose

Section titled “Purpose”

Exclude a construction or building product from the calculation without deleting it from the building model.

Prerequisites

Section titled “Prerequisites”

The element isn’t locked by a parent library lock.

Steps

Section titled “Steps”
  1. Find the element in the building model tree.
  2. Clear the checkbox in the Include column (or use the view menu’s “Include in calculation” view).

Result

Section titled “Result”

The element stays in the building model: visible, but not contributing to the calculation. It’s one of four ways to make a building product contribute zero (see box below), and they don’t mean the same thing.

Trap: renovation, lifespan 0, offset start beyond the assessment period, and include-in-calculation turned off all produce a zero contribution, but only some of them reset all impacts on the element, and only one depends on calculation mode. Use the right method for the right situation.
