 If you were to wake up today, get in your car to go to work, found that you need gas for the car, proceed to your favourite service station and find that the price of gas has doubled from yesterday. You look across the street and find the competitor has the same price.

 Because of our cold climate 11,000 Degree days (6,003 DD), very small solar gains in the winter months and a very low sun angle, the solar gain that we get from November to March is very small and this is the time we need the heat for our homes. Because of our cold climate 11,000 Degree days (6,003 DD), very small solar gains in the winter months and a very low sun angle, the solar gain that we get from November to March is very small and this is the time we need the heat for our homes.
 +[Regina is on latitude 50.45N, very similar to the first Passive House in Darmstadt-Kranichstein with latitude 49.7N]
  
 So can you store heat from the summer to heat the house in the winter? The solar storage would have to be very large and very well insulated. As a committee we examined these problems and came to the conclusion that solar heating of a home in Saskatchewan was not appropriate,​ but we could and would build a Conserving House appropriate for Saskatchewan. So can you store heat from the summer to heat the house in the winter?

 What did we learn? Conservation is much less expensive than solar. For every dollar we spent on reducing heat loss from the house, with a better air barrier and more insulation, we saved at least 10 dollars on the size of solar collectors and equipment needed to achieve the same thing. Now let us look at some of the details of the house. What did we learn? Conservation is much less expensive than solar.
