Geographical Orientation of the Home
The orientation of the home is a relevant factor when implementing your maintenance program. The geographical direction your home faces directly impacts the rate at which your home loses or maintains moisture levels in the soil. Generally speaking, the west and south sides of the house will receive more sunlight than the north and east sides of your home, as shown in the sun diagram below.
This is particularly important during the summer months. In the summer, the sun is in the sky longer and at a greater angle. The greater angle means the suns UV rays do not have to travel through as much of the earths atmosphere. This causes the sun to have more of an impact than in the winter when it is lower in the sky and there is less daylight.
The wind is also an important factor in moisture loss when combined with the orientation of your home. Geographical Orientation of the Home Large scale wind comes from the west. Locally, wind can come from any direction, but generally it comes from the west, which means the west side of your home is exposed to the wind and the effects of the wind. In other words, wind can cause quicker water evaporation if it comes into contact with unsheltered soil.
If, for example, the front of your house faces south and has very little vegetation to shelter it from the sun and the wind, the front of the house will require more water to maintain constant moisture levels around the foundation.
