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.

The sun-dial time is used on our chart as it more universally applies at different meridians on a given latitude, than does our standard time which, for the sake of timepiece uniformity, is a compromise based on mean solar time. As the earth’s orbit is such as to make the sun gain a little or lose a little in crossing the meridian each day during the year, the total annual time of the sun is averaged into uniform daily periods, which in turn are divided into 24 uniform hours and referred to certain meridians the world round, about an hour apart.

These angular distances, in terms of degrees, are called amplitudes, north or south, and must not be confused with the degrees of latitude on the earth’s surface, indicated by the numbers along side of the sun, though intimately dependent upon them. The amplitude of the horizon point, where the sun rises and sets from time to time during the year, always depends upon the latitude on the earth’s surface where you happen to live, as may be seen by following with your eye the direction of the arrows of latitude through the amplitude circle.
