The first rule of design is to exceed building codes.  Remember, building codes are the minimum requirement.  Do not go for the cheapest or the least acceptable, do better.  Maximize your insulation and minimize the air infiltration.  Install an air to air heat exchanger to ensure fresh air and minimum heat loss.

Passive Solar Basics

In the northern hemisphere, the sun is in the south.  Glazing should be maximized on the south side of a structure.  Glazing (windows) should be minimized on the North and West.  Here’s why.  On the North side, glazing only leaks heat to the outside.  “Cold north winds” in the winter time will penetrate the structure and make it colder.  On the West side, remember the sun rises in the East and sets in the West.  In warm summer weather, the hottest sun is in the afternoon.  Western facing windows absorb all of the solar energy in July and August and soon the house – on its own – can reach 80 or 90 F!  Carefully plan western facing windows.  They need to have shading, coverings, or special low UV glass to minimize overheating in the summer.
