Windows incorporating these glazings are a good choice when solar heating is not the goal. For windows intended for solar heating, obviously a high shading coefficient is needed. Note that low-e coatings also reduce the glazing's shading coefficient, and may not be the best choice when solar heating is desired. Another consideration is to choose landscaping that complements the energy design of buildings, particularly in homes and small commercial buildings. Because overhangs are impractical for these windows, the strategic placement of trees and shrubs is often the best option for shading.
Landscaping has other benefits, including natural cooling and protection from the wind.
