Fabric like materials that are wrapped around the exterior sheathing of a building to eliminate air infiltration while still allowing moisture to escape from the wall cavity, can significantly reduce energy costs.
Movement or leaking of air through the exterior shell of a building, often measure in “air changes” which represent the complete replacement of interior, conditioned air with air from outside the structure.
The construction of a building using sections that are built in a factory and then assembled together in the field to complete the structure. Modules usually include finished interior and exterior components as well as mechanicals that are spliced where modules meet.
Concrete slab construction used in areas with extreme expansive soils, involves the installation of metal cables at opposite directions in the slab which are then put in tension to eliminate cracking and separation due to soil movement.
Architectural drawings used for the purpose of establishing the general design of a building before detailed, or working drawings are finalized, usually used to determine preliminary cost estimates and secure owners approval for final design.
Plaster, made with Portland cement, sand and water that is sometimes used as an exterior finish, synthetic stucco, also known as EIFS, is more commonly used in residential and commercial construction today.
