Step-by-step explanation:
Designing a sun-protected house involves careful consideration of materials and placement to provide adequate shade and prevent excessive heat gain. The following materials can be used for each component:
Roof: To protect from the sun's rays, the roof should have a light color to reflect sunlight and prevent heat absorption. Materials like concrete tiles, metal roofs, and asphalt shingles with high solar reflectance are suitable for sun-protected roofs.
Walls: The walls should have a high thermal mass to absorb and store heat, thereby reducing heat transfer inside the house. Materials like brick, stone, and concrete are ideal for sun-protected walls. The walls should also have an insulating layer to prevent heat transfer through conduction and convection.
Windows and Doors: To reduce heat gain from windows and doors, they should have low-e coatings and insulating frames. High-performance glazing like double or triple-paned windows with gas fills can reduce solar heat gain while allowing natural light to enter. Shades, blinds, and shutters can also be used to provide additional shading and control the amount of light entering the house.
In addition to these materials, the house should be oriented to reduce solar heat gain, and landscaping elements like trees and shrubs can be used to provide additional shade. By using these materials and design strategies, a sun-protected house can be created that is comfortable and energy-efficient.
