Building science is a field of knowledge that draws upon physics, chemistry, technology, architecture, and the life sciences. Knowing the physical behaviour of a building for a system and the way this affects energy efficiency, durability, relaxation and indoor air quality is imperative to innovating high-performance buildings. Contemporary construction science tries to work with all versions of their construction, and also to employ empirical methods to solve all design issues.

Components are systems that have to be appropriately incorporated by designers to achieve defined levels of functionality. Construction science gives a disciplined way of handling the physical needs of buildings that are harmonious with the architectural design and the construction building processes.
