Building Systems for Interior Designers covers some subjects, such as heating and air -conditioning systems, that are rarely included in other parts of an interior designer's education. Other areas, such as lighting, typically have entire courses devoted to them, and are given a less thorough treatment here. While some topics, such as acoustics or fire safety, are intimately tied to the work of the interior designer, others, such as transportation systems, involve the interior designer less directly, or may be absent from some projects altogether. This text assumes that the reader has a basic knowledge of building design and construction, but no special training in physics or mathematics. I have sought to cover all the related systems in a building in sufficient depth to provide the reader with a good general understanding, while avoiding repetition of material most likely covered in other courses and texts. .
