Just run the comparison in both locations, and compare the results.
The two locations, I mean, the IWEC location and any other available weather file location nearest to you.
I have also modify the location of the IWEC in the epw to match the local site location, so that the local solar position would be used without generating a warning.
There were only 65 zones in Australia for green star grading. I do not think that the weather condition is that important.
In Singapore, there is a 5°C difference in the outdoor air temperature the city area and the reservoir area. The IWEC location is at the North East corner airport which is a cool area. My apartment was in the center of the island,but near a reservoir and was cool all the year around. I do not know how they set the baseline. I know that the comfort standard is not as tight as the ASHRAE Fenger limits, in order to save energy.
For the purpose of answering the reviewer question, you should look at the latitude, nearby mountain shielding, water lakes and sea current. I think, you have mentioned a few of these yourself.

Thanks for all the replies. In this case I'm going break down my reasoning as follows. The baseline building should represent a "average" code compliant building for the same climate / geographic location. This is best defined using the CDD and HDD data for the dataset with origin closest to my proposed building.
Then I need a dataset for hourly weather data for a statistical weather year. In my case the closest available data set is roughly 40 km away from the building location (no IWEC exists for the closest weather station where I have the CDD/HDD data from.
This seems to be both the most accurate, and defensible way to proceed. If both the proposed building and the baseline building experience a weather year slightly warmer and the next year slightly colder, the relative performance of the two should remain almost identical.
