Overview

Building Automation And Smart Buildings

The concept of building automation, or smart buildings, involves integrating all of a facility's systems into a centrally controlled network with IP-based structured cabling. Smart buildings provide several benefits, including improved safety, reduced labor and operating costs, simplified asset management and energy efficiency.

According to the market research report from Fortune Business Insights - the global smart building market is projected to grow from $67.60 billion in 2021 to $265.37 billion in 2028 at a CAGR of 21.6% in forecast period.  The growth of this market is driven by the increase in demand for energy-efficient systems, the growing need for automation of security systems in buildings, and advancement of IoT in Building Automation Systems (BAS).  Furthermore, the emergence of 5G technology and growing smart-projects is expected to create many opportunities for the growth of this global market.

Building Automation and PoE Devices

Building Automation Systems leverage the convergence of low-voltage building systems with an Ethernet network and IP addressable devices throughout the building. With an Ethernet network, all of the smart building devices can be connected to the network and powered by the same network cable. Power over Ethernet (PoE) allows system integrators or network administrators to deploy powered devices at any location, regardless if a site has electrical outlets. The devices connected to the PoE network in a smart building include:

  • Access control door locks, badge readers, parking gates, turnstiles and intercoms
  • Surveillance cameras
  • Wi-Fi access points and routers
  • Thin clients
  • Synchronized clocks
  • Electronic signage and emergency messaging systems
  • Thermostats and HVAC controls
  • Intelligent LED Lighting

Power over Ethernet is supplied by power sourcing switches that inject power over copper UTP cabling to all the devices in the building. These switches are located in a centralized network server room that controls the building system.

The challenge to network managers and system integrators is that in larger buildings and facilities with secure parking, the distance from the network server room to PoE devices will often exceed the 100 meter distance limits of UTP copper cabling. Fiber optic cabling overcomes the distance and bandwidth limitations of UTP, but fiber does not carry electric DC current.
