Inlets and outlets usually should not be located directly opposite each other because the only area that will be cooled will be in the direct path of the air flow. If the air has to take a longer path between the inlet and outlet, more of your house will be cooled. Another way to enhance ventilation is to use a fan to pull air into the home from the cool, shaded side of your house. Additionally, a slightly open window will create a better air current than a fully open window. This is like having a gigantic radiator above your living spaces.
Attic ventilation serves two purposes.
First, it cools hot attics during the summer months. Secondly, it removes moisture from insulation and other building materials that may accumulate in the attic during the winter months. In the summer, the sun s heat puts a strain on your home s air conditioning system. This heat builds up in the attic and can be stored there even on cool summer nights. This means higher air conditioning bills and increased strain on all the components of the air conditioning system.
