Saw one built south of Newtownmountkennedy in the early nineties with a conservatory and IIRC triple glazing, south aspect.
All windows open in the summer, flies everywhere, it was still like a sauna.
Ireland can be both very cold [-16!] and quite hot [30+].
Its not tropical, but it can be very, very humid.
Timber frame and log cabin cosntruction were developed in the main for colder [and thereby drier] climates.
Snow is not rain, it is snow, and cold weather dries out the air and timbers exposed to it.
For example, wood pellet moisture content affects the efficiency of their combustion.
In a cold country, leaving them outside for a while dries them to 14%, circa no matter what they arrive at.
In Ireland they can arrive at 14% but unless kept in a specially prepared space they can rise to 16-18% because of the dampness of our climate.
In fact, they can spontaneously combust due to this dampness and the heat generated by growing bacteria.
If you don;t beleive me about self combustion, do some research here.

As you can see, self ignition is a known quantity.
Its little tell-tales like this that can point the way for professionals to discover quite obvious inconsistencies between methods of construction developed and used in cold dry countries and here.
Other issues you may want to consider and the causes and prevention of toxic mould and the effects of a heated sealed environment on asthma sufferers.
