I have made a thermal model for a building and I try to calibrate it to the real building,and the objective is the cooling load.I am going to find the optimized parameters (as input of my model) to have a calibrated model. I have 3 columns of parameters and 1 column of output saved in an Excel file. I think the GA is the best way to find the optimized parameters. As I can understand first I need to find a fitness function for my data Q=f(x1,x2,x3). Could you please tell me what is the best way to do it?
I really appreciate your help and time.

I don't know why you think GA is the way to go, but here is an example of nonlinear curve fitting using several different solvers.
