It is still winter here in Wisconsin but I was able to enjoy 70°F inside the bus without having to resort to any heating aside from the passive solar gain that this nice sunny day provided. Of course it was the warmest day so far this year with the temperature outside peaking at 48° F.
This got me to thinking about the approach of spring and summer. When the outdoor temperatures rise I am afraid that I will be cursing that solar gain which worked so well for me today.
I would like to live in the bus sometime later this year,but first I have to install insulation. Since I don’t have a heated indoor space in which to work on the bus, I am presently waiting for warmer temperatures so that I can spray insulating foam. I am sure that this will make a big improvement in controlling the interior temp, but I am worried that a mere 2 inches of foam in the roof is not going to keep me as cool as I hope.
And there are the windows to consider as well. I intend to remove about 40% of the windows. This will certainly help reduce heat loss in the colder weather. I am hoping it helps with controlling heat in summer too.
I think I have to insulate for the worst case scenario, because with solar electric panels on the roof, I am not going to be able to rely on shade as much as I might otherwise.
Awnings are another consideration. If I can keep the summer sun off of the window glass with the use of some kind of awning it may be something worth looking into.
Much to think about. Constructive input from experience Skoolies is welcome and encouraged. — Matt
