Equivalent Single Dwelling calculation in schedule?

[Mikey_B]

Aloha,

Our jurisdiction is now requiring that we calculate and report the ESD (water usage) using this formula:

ESDs = [1.15(Baths)^1.3 + Beds + 3] / 10

Is there a way to have a schedule do this calculation after inputing the number of bedrooms and bathrooms?

Operating system used: Mac Apple Silicon Ventura 13.5

Schedules can not d any calculations other than simple summation of columns/rows.

Classification and Properties can be used though.

Look at Properties with expressions where you can create a property with this formula.

There are also many posts here.

You would need a property for the number of beds, another for the number of baths and then a third to do the calculation.

You could than associate these to a zone for the apartment area where you can adjust the number of beds/baths for each zone and then get the resulting calculation.

You can then schedule the resulting property or even use it in a label you can add to each zone in plan.
