I think I’m going to break down and turn the heat back on. High today is 11c/51f in #yeg with no solar gain, so we’re down to 17c in the house.
Last few years I’ve turned off the furnace in mid March-ish and been able to coast on solar gain until September. Even days at -15c with sun made a net gain.
But these last few cool, dreary days means I’m breaking my streak after May long.

This morning it was -4 F and by early afternoon it’s warmed up to 12 F. I think the furnace has turned on just once in the last 4 hours. Many south-facing windows and great insulation for the win!
Our house uses about 750 Btu/hour/delta°F and there is a reasonably large thermal mass inside the outer insulation envelope.
Koji, our older gray boss kitty approves!

This ancient knowledge is making a comeback in houses, but where it is really making a huge impact is in greenhouses. Even in colder climates where temperatures can reach -40c(-40f), passive solar designs are enabling greenhouses to run all-year.

Passive Solar ☀
Within Arizona(USA) is a beautiful cliff-dwelling built by the Sinagua people in 1100-1425 AD. Montezuma Castle (renamed to this by colonizers) has around 20 rooms, and is built using a method that today people call “passive solar building.”
The design ensured the buildings were hit with the heat of the low-winter sun, but protected from the high-summer sun by overhang.

> While these are manufactured ovens, the principle is simple enough you can make your own out of cardboard, black paint and a transparent lidMore on this here:

I've seen very effective solar dehydrators based on similar principles. See;
