Architectural Design for Hot-Dry and Mixed- Dry Climate Zones
DOE- Hot Dry & Mixed Dry Climate Zones
Hot-dry and mixed-dry climates present several challenges for home building.
* The intense solar radiation imposes a large thermal load on houses that can increase cooling costs, affect comfort, and damage home furnishings. This section includes some of the best methods to minimize the impact of solar radiation on the building, its mechanical system, its occupants, and their furnishings.
* Annual precipitation in these climates is less than 20 inches. Nevertheless, a brief period of heavy rain can deposit several inches of water onto a building. Improper irrigation can be a major moisture source, leaks can cause significant damage, and indoor sources of moisture can be a problem. If water collects in an area that cannot quickly dry, deterioration of the building will occur. Managing fire risk, particularly in terms of exterior claddings and landscaping, is an important issue associated with the dry climate.
