Sun Exposure
What is Sun-Hour Exposure Analysis?
Sun-hour exposure analysis is a critical assessment tool used to measure the amount of direct sunlight and help optimize the design to ensure natural light and the comfort and well-being of occupants. This tool is essential for proposed developments, open spaces, landscapes, and gardening.
