Building science is the collection of scientific data and knowledge to assist with the analysis and control of buildings and building environments. Building science in this guide is associated with building envelope, moisture management and indoor air quality.
Building envelopes are a physical separator between the indoors and outdoors and are comprised of many components including walls, floors, roofs, windows and doors. The building envelope is designed to support indoor comfort, manage moisture and protect us from exterior elements.
The building enclosure should manage all factors that can migrate into and out the building whether it is water, light or sound. The building assemblies comprise the foundations, above grade walls and roofs that make up the enclosure. How the building is designed and constructed makes the difference on how the building performs. Additionally, building longevity is based upon how the building performs keeping the outside elements out.
Many disciplines are involved in design and construction of a building including architectural, structural, mechanical and construction management. During the process, failures can occur including inadequate building design and elemental intrusion which affects building performance post construction. These can prevent the building to operate properly. Building science investigations provide information so corrective measures can be implemented to fix pre or post construction issues.
