Most of us have been experincing the arctic polar plunge into the US in the last few weeks, me included. We have had frozen pipes, impassable roads, school closings and more snow and ice that I'd like.
I have extreme cabin fever.
But, there's a lesson I learned in all of this. I have long been a supporter of passive solar energy but it really has come to the forefront in this awful weather. Usually on cold days, I run out and start my old truck and let it warm up before I try to go anywhere.
Despite recent temps in the single digits, we have had a couple of days with (cold) sunshine. On those days I try to get out for perishable groceries if the roads are passable. I've discovered that even in 5ºF weather, the cab of my truck is warm and toasty in the sunshine, without any need to warm up the engine, thus proving how solar gain really works even in dreadfully cold weather.
It gives me a great prospective now on designing wit6h passive solar gain in mind.
