today in heating and ventilating, they have been toyed with to date only by higher mathematics, which concludes that there are great potential deficiencies to be had by measured evolution of shape control. In our own tests we had discovered the relative degree of that shape importance to heat savings in the coincidence of drag and heat loss curves.
"Having been in the building business in the 20s, I was particularly interested in heat losses because my material… was a very good insulating material… We discovered that heat losses in buildings of comparable tolerance of joint fittings was directly proportional to the drag. Houses represented very large obstacles, and the low-pressure tails on buildings are very long. They stream out to 200 to 300-yards in relatively mild winds. Houses are usually surrounded by trees and other houses and those tails get mixed up with each other, but if you discover a house out in the open you can observe this 300-yard pattern in the snow shaping as seen from an airplane.
“Air being highly compressible as it goes around large objects like houses you get a fairly high degree of compression at the widest beam of the obstacle to the wind. The result is a very”
