Hi,
I am working on a large parametric project in which I have to compare different model and variable at the same time.
I am using JEP+EA.
The objective functions (and the formulas) are:

Electricity; kWh; (c0+c1)/1000/3600
Heating; kWh; c2/1000/3600
Cooling; kWh; c3/1000/3600
Lighting; kWh; c0/1000/3600

Because of the floor area change for each model, to compare the results I need to have values in kwh/m2.

Is there a specific formula?

Thanks
A.

Hi Antonio,

To normalise it per floor are you need to extract the total building area first. I think that total building area can be found in sql outputs. You can watch Youtube tutorial on how to extract data from sql (https://www.youtube.com/watch?v=9Cf0yHYxd-M).

Total building floor area should be somewhere amond tabular data and the sql command should lool like (from top of my head): SELECT Value FROM TabularDataWithStrings Where RowName = 'Total Building Area'

Having extracted total floor area you would be able to use equation to create optimisation objective. For example, if your total floor area is c4 than normalised heating would be:

Heating; kWh; c2/c4/1000/3600.

Cheers,
