Call me a dinosaur.

The older I become, the simpler I want things to be. My view of Building Science and the home retrofit business is progressing (regressing?) in this manner. A home is a shelter. Most shelters are some kind of a box. You can have a box that leaks or one that is airtight. Most climates prefer air tight, as do I. The best part of tight is control. Temperature, moisture, odor can be simply                   controlled in a tight box with little fuss and low cost. So tighter is better. Move the air around inside the box, provide a filtered fresh air exchange system some thermal modulation and voila' all the shelter needs are met.
