As a Canadian user, I sympathize. The current version of eQUEST (3.64)
will only generate the 90.1-2007 appendix G reference building for US
locations. In that .pdf describing the LEED compliance analysis, one of
the "future features" is international locations. (It looks like you can
just put the long and lat in but it won't accept them ... we won't talk
about how long I spent trying to do that!) So, what you end up doing
for now is selecting a US location with the same climate zone as your
site, generating the reference building and then opening that as a
separate file and making any further required modifications -- such as
setting the weather file/project site correctly.

Given that this is the 1st generation of eQUEST that creates a 90.1
reference, you want to go through that reference building very carefully
to ensure that it is correctly representing the reference you need to be
compared against. eQUEST saves you a lot of work by automatically
generating the reference -- but you cannot use it blindly (yet).

Good luck!
