It's really amazing how seemingly small things make a huge difference. Direct sun with thoughtfully located windows that actually consider the fact the sun's angle changes throughout the year makes an enormous difference on their own. Add in all the other layers of insulation, thermal bridging, sharing a wall with another property etc. and it's a completely different home with a vastly reduced energy profile.Interesting video on the passive house. I'm not surprised that proper insulation, etc... can support the heating of a house. Even in my older drafty house, with older windows, the house warms a lot just from the sun. The two rooms where we have computers and other electronic equipment tend to get too hot actually. One of those rooms is in the room in the basement and has some servers and other IT gear. It's gets heated fairly easily if the door to the room is closed.
Same applies for gardening and outdoor spaces. Thoughtful location of wind-breaks, consideration for windows and reflected light extend patio season and growing season by several months in many situations even in Calgary's climates. Lots of yards could probably grow plants a several growing zones further south with the slightest bit of attention to this type of thing.
