American Face Brick Association, Orienting the House: A Study of the Placing of the House with Relation to the Sun's Rays
“ You have certain rooms in which you especially want the sun, morning or afternoon; or a porch you want as much in the shade as possible, let us say. In tracing the direction of the sun’s rays, do not think of them as converging or as spreading out. Think of them rather as coming in great, broad, parallel bands so that no matter how large your house may be, the moment one side gets the sun, the opposite parallel side falls into shade. The broad band of parallel lines streaming from the sun, as seen on the chart, is meant to illustrate this. ”
