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.
