The Update Area Totals task runs the below calculations.
You can access the Update Area Totals routine from these locations:
Note: If your site adheres to conventions established by the BOMA 2017 Office Space Standards document, you will want to examine the BOMA 2017 Method A and Method B buttons on the Building Performance report. These buttons calculate various area values based on the BOMA Method A and Method B standards. See Calculating Rentable Area According to BOMA 2017 Methods A and B.
Note: These calculations are for a room transaction-based space inventory. If your site is using the non-transactional space inventory tasks, see Calculations for the Update Area Totals Task (Non-Transactional).
