Building physics is "the physics of the built environment". These concern the physical aspects of the building space and of building structures and installations. The physical aspects are light, heat, air, moisture and noise.
The built space includes both the man-made outside and the inner space. It is then the use of space as far as the physical aspects are concerned.
Under construction constructions we specifically understand the separation constructions. On the one hand, it is about the performance that the constructions provide in maintaining a desired physical environment (and the amount of energy involved) and, on the other hand, physical performance with regard to the maintenance of the constructions themselves.
In addition to building facilities, installations for the maintenance of the indoor environment are usually used. Designing these installations does not belong to the physics of the built environment. However, it belongs to the physics of the built environment to determine its physical performance, in a proper balance with the physical performance of the separation constructions.
