ITU‐T's Technical Reports and Specifications 483 Figure 8 – Typical systems in an intelligent building Photo credit: courtesy of IBI Group 7.1 Physical Infrastructure Physical Infrastructure is a \"given\" in an intelligent building, in terms of systems that will be there independent if the building is a smart or not. Therefore, these aspects are not discussed in detail in this report. However, it is important to recognize that these very systems which need to made more intelligent and communicate with one another in an intelligent building. These aspects are covered in what is being termed as \"Building Control Systems\". Air Conditioning Lighting Elevators Water and Plumbing Electrical Fire Alarm Façade & Interior Décor 7.2 Data and ICT Infrastructure An intelligent building is predicated on the use of data and communications and typically includes all the aspects related to data and communication both physical (hardware) and software. 1. Networking Infrastructure 2. Include Cabling, IP Networks, Voice, Video, Data & Wireless 3. Data Security It is essential to make the different systems talk to each other and for software based smart decisions, the ICT /Data Infrastructure is critical. This ICT infrastructure is not only for ICT related systems such as Voice, Video, Data, Wireless, Data Security etc., and associated enterprise software applications, but forms the basis on which the different control systems can communicate with one another.
