I'm modeling a project oustide the US with Carrier HAP. This place is not in the weather data base of HAP, or DOE's web page, and even though it was, HAP does not allow IWEC files, so I'm kind of stuck.
According to Ashrae 90.1 2007 appendix G2 Simulation General Requirements under G2.3 it states that when weather data is not available, designer should select the one that best represents the climate at the construction site, but also states that it shall be approved by the rating authority, wich in this case will be the reviewer.
So my question is, is anybody having or have had this same problem before, how the reviewers behave on this cases. It's been difficult for me finding similar weather data in other places. I have one for example at the same latitud but much colder on winter. Does it really matters?, since at the end you are comparing both as designed and baseline with the same weather data. I guess could have an implication on the unmet hours.
Best,
