Mexico City weather file

I've been trying to investigate energy consumption for a hospital in Mexico City. The space heating is giving me a zero for a few months then dashes for the rest. I've modeled based on climate zone 3. I've tried all three weather files for Mexico City, Mexico88, 90 and 91. In efforts to verify the model was correct, I changed weather files for different locations in the US. I even tried a US climate zone 3 and it showed some space heating. Is this an issue with the weather file or is there just no real space heating. The system used was a dx with electric reheat. The attached pdfs show the numbers.
Thanks for any direction provided.

Brian,

Just a quick look at your pdfs shows that you have very high lighting and
equipment loads, you also will have high occupancy loads, which means a lot
of heat to your spaces. It could be that this heat is more than sufficient
to meet your needs and that cooling is the mode you are in most of the year.
Without seeing you model inputs, I don't know whether you are using
economizers or not or any sort of heat recovery. If you are that might also
be an influence.

Regards,

Carol

Brian,

The previous response may address your needs. Nevertheless, being able
to view the weather data is useful. You can do this by using the weather
file converter. See link to
