We are pursuing the Option 1 - simulation path. The total regularly occupied area (ROA) reported for the simulation is linked to the PIf3 credit. This represents a challenge when creating the simulation model geometry, as it is difficult to represent the ROA in the model spot on (i.e. due to the model grid setting). We communicated how to represent the area in the best way with the software developer (IES VE), who actually advised us against trying to recreate the geometry with the highest precision possible and recommended focusing on robustness of the model instead.

So here comes a question - is there any allowable difference / tolerance range between the ROA reporeted from the model and in PIf3? (NOTE: this has already been touched on in the last topic below [topic net area vs gross area (simulation) from Jan 12 2016], noting that up to 10% difference in area is allowable. Can you please confirm that?). Thank you in advance
