[ ] The sun's radiation may not be always beneficial, depending on the building site's climate.
[ ] Building east and west elevations are generally warmer in summer and cooler in winter than southern elevation.
[ ] Buildings with closed forms and courts are desirable in hot-arid and hot-humid climatic regions.
[ ] The sun's location can be defined knowing its altitude and bearing angle.
[ ] Exterior shading devices are less efficient than those located within a building's spaces.
[ ] Thermal conductivity of building enclosure is an important element in selecting its construction materials.
[ ] A material reflectively depends on its color and texture.
[ ] Light colors tend to reflect less radiation than dark colors.
[ ] Depending on their proximity, height, and orientation, trees and adjacent structures can be used to provide shade in addition to shading devices.
[ ] Vertical louvers are not effective for eastern or western building exposures.
