A: Yes. Building renovation is growing and so the need for installing smart building management systems in existing buildings with no infrastructure is becoming more vital. For this reason, manufacturers have invested a lot in Research and Development of products that can be integrated in a system by using the existing infrastructure. Apart from Power Line devices, which take advantage of the existing electrical installation to network, most of the newer technologies will incorporate devices that can network with Radio Frequencies (RF) or otherwise e.g. Zigbee, Zwave, etc.
