A4 Building Materials, Assemblies, & Envelope Systems 

Fired Bricks and Clay Blocks: The artificial rock that man invented since unmemorable eras. It consists on baking clay forms to harden them and make them stronger and more long lasting. In India there are still standing fired brick structures over 4000 years old.  Click Group 1 or Group 2 to see the examples.

Concrete: A composite building material made from the combination of aggregate and a binder such as cement. The most common form of concrete is Portland cement concrete, which consists of mineral aggregate (generally gravel and sand), portland cement and water. Click Group 1 to see the example.

Fabric: The tent is the home of choice among nomadic groups all over the world. Two well-known types include the conical teepee and the circular yurt. Modern buildings can be made of flexible material such as fabric membranes, and supported by a system of steel cables, rigid or internal, or by air pressure. Click Group 1 or Group 2 to see the examples.

Glass: Clear windows have been used since the invention of glass to cover small openings in a building. Glass panes provided humans with the ability to both let light into rooms while at the same time keeping inclement weather outside. Click Group 1 or Group 2 to see the examples.

 Metal: Metal is used as structural framework for larger buildings such as skyscrapers, or as an external surface covering. There are many types of metals used for building. Corrosion is metal's prime enemy when it comes to longevity. Click Group 1 or Group 2 to see the examples.

Plastic: Plastics vary immensely in heat tolerance, hardness, and resiliency. Combined with this adaptability, the general uniformity of composition and lightness of plastics ensures their use in almost all industrial applications today. Click Group 1 or Group 2 to see the examples.

Materials & Construction: Materials selection criteria, considerations, and constraints for: optimizing health, durability, maintenance, and energy use reducing the impacts of extraction, manufacturing, and transportation. Click Group 1 or to see the example.

Materials & Construction: Enclosure performance in relation to air, water and thermal characteristics. Click Group 1 or Group 2 to see the examples.

Materials & Construction: Consideration of life cycle impacts and results of life cycle assessment. Click Group 1 or to see the example.

Materials & Construction: Construction waste reduction plans; strategies to promote recycling during occupancy. Click Group 1 or Group 2 to see the examples.
