Solar azimuth - how the sun moves across the sky

The solar azimuth angle is the angular measurement of the sun in a clockwise direction from north. When building a house it is important to think about the solar azimuth because it affects which sides of the house receive morning or afternoon sunlight at various times of the year. Most homes are built with north-facing windows to optimise the low winter sun elevation, but few homes are built with the summer azimuth angles in mind.
