SHGC of less than .40 is great for East, West and even North. But on the South side, you want a higher number (.60 or above) to let the warmth of the winter sun in. prelitzdotcom

Great. Please post more of these. People need to be educated on passive insolation. Very well drawn and easy to understand. A Good job!
