Stupidly, I did not keep the URL, however, I do have a copy of the full pdf specs which I can forward to you if you give me your e-mail - I suggest you do so in the form of somebody at internet provider dot com to avoid spam bots

If you prefer not to do this, I enclose the main link to the Passivhaus site here.

However, it is my understanding that, rather like a church, there is a tendency to schism in the Passivhaus movement, complete with cries of heresy, and some would not consider a house not using mechanical ventilation to be part of the true faith.

You should note however that the standards called for for the UK, a mild maritime climate, will be much different to your needs in Saskatchewan, which would need something similar to Scandinavian standards - I believe they also use mechanical ventilation, although presumably if you want to be independent of the grid you could perhaps rig a custom variation.

To be frank, this 1954 house is so leaky (ice inside) that it is going to take an awful lot of insulation, new windows (single pane glass in Saskatchewan! %%$^^%$!!! What were they thinking!), and tightening before we have to start worrying about air exchange. We've added attic insulation to the last two houses we've lived in in Canada (none before us in old houses). Canada has alot of low-hanging fruit that can be picked fairly easily in purely pragmatic terms. The problem is that ~50% of the housing in the country is rental (no reference, sorry) so there is no incentive for landlords who typically don't pay the heat to upgrade, and well, they don't. Such legal problems prevent much obvious improvements in North America. Fortunately we now own, but if we stay here for more than a year, we have a very large amount of work to improve this building.

I've e-mailed the info you want - actually, I managed to dig out the URL's for most of it, and they are in my reply to Black Dog, but I've mailed the rest.

Sounds like you have a long way to go! Single glazing in Saskatchewan, forsooth!

I can't get an e-mail through to you - you should be OK with the links I've posted here though.

I don't know if it is practical in a rented property, but a air heat pump has now been designed for Canadian conditions, and is good down to -30C, the advantage being of course that it is a lot cheaper than a ground-source pump.

You also get air-conditioning for the summer thrown in.
