Yurt in northen Scandinavia: Tips?

[Seigan]

Hi guys.

I've started to build a 8 meter (~27 foot) yurt on a mobile trailer that hold some of the utilities such as fire place, bathroom, kitchen and sleep-loft. The goal is to have something that is a mix between cabin, trailer and tent tha can work of grid and part time home year round.

Now this wierd hybrid is thought to be placed in northern Sweden. That means long cold (down to -40 c) and dark winters, short and sometimes cold summers (0 to +35 c) with midnight sun. The spring and the falls are is usually very wet, either by rain or snowmelting. The winters have up to 6 foot of snow but usually 2-3 foot but the air is often very dry as long as it is below 0 c. In the summernights thick fog is very common. There is wind but it rarely catches very high speed as the landscape is quite uneven and clad by (mostly) pine or spuce forests. I guess the cilmate is pretty similar to north east US or parts of Canada or Alaska.

So now to my questions:
1) Any ideas on how to manage the moister? Any special materials for the canvas and isolation? Any special demoisterise systems? We are also giong to cook and shower inside, and also our breaths etc creates moister from the inside in addition to the weather from the outside.

2) Any ideas about angles of the roof to manage heavy snow? I know that tradtional mongol gers are rarely above 25 degrees. On ordinary villas here they are often above 40, sometimes 60. I thought of around 40 degrees as it also are a round building sloping in many angles at once. Do you think it will be enough?

3) I have seen reinforsments done to the roofs to manage snow. Like 2 by 4 beams, bridges and vires between the beams however the beams often do not lay on the walls and only sometimes on a pillar. There also seems to be fewer beams when thicker beams are used. Any one that know how much one would gain with this types of solutions compared to a tradtional solution with many thinner rounded beams that lay directly on the walls (in the top X)? Pros and cons?

4) As we will not be in the yurt all the time (it is thought to be a year round vacationhouse) we are worried about deteration while we are not there because of stale air, damp, mold etc. We have thoughts about put in a passive solar pannel that heats up the air and a fan on solarcells tha push it in when the weather is dry and sunny. We have also ideas about compost

heating

system (give up to 60 c for up to 18 months) used to passivly heat a floorheating system to keep the temprature while we are not around keeping the fireplace going. Any more ideas to prevent damp and stale air while not living in the yurt?


This is our first time building our own yurt so any tip from you more experinced builders that have tackled the same problems in the past is very welcome!!

Thanks
