Passive solar works, just how well we are about to find out.

No heat and we haven't frozen yet.

So, the passive solar home I am building is about to be tested by mother nature. With some of the coldest weather we have seen in several years approaching and still no heating system installed. Well, I quess you could call the Thermal mass windows a heating system.

We shall see how well the house is insulated because this is about to happen. Although we have experienced some very cold nights and days, the cold that is predicted will be 4-5 days with lows around zero and highs in the upper teens and very limited sun. How cold do you think
the temperature in this unheated house will get??
Take a quess!
I predict the lowest temperature the house will experience will be no lower the 38F. not a best case senario, but not bad for a home in New England with no heat.

I will post a video of how the house performs and lets see how well the Sturctural Insulate envelope works

Here is a video showing how well the house performed on
January 1,2009 with no heat in the house and
a night time low of 4.5F
