• Building Management Systems
The function of Building Management Systems is central to 'Intelligent Buildings' concepts. Its purpose is to control, monitor and optimize building services. The potential within these concepts and the surrounding technology is vast, and our lives are changing from the effects of Intelligent Buildings developments.
Building Systems linked to a BMS typically represent 40% of a building's energy usage. If lighting is included, this number approaches 70%. BMS systems are a critical component to managing energy demand. In addition to controlling the building's internal environment, BMS systems are sometimes linked to access control or other security systems such as closed-circuit television (CCTV) and motion detectors. Fire alarm systems and elevators are also sometimes linked to a BMS, for monitoring.
BMS is used for linking to:
Illumination (lighting) control
Electric power control
Heating, Ventilation and Air-conditioning (HVAC)
Security and observation
Fire alarm system
Lifts, elevators, etc.
Closed-circuit television (CCTV)
Other engineering systems
• LAN Cabling
Cable is the medium through which information usually moves from one network device to another. There are several types of cable which are commonly used with LANs. In some cases, a network will utilize only one type of cable, other networks will use a variety of cable types. The type of cable chosen for a network is related to the network's topology, protocol, and size. Understanding the characteristics of different types of cable and how they relate to other aspects of a network is necessary for the development of a successful network.
The following categories discuss the types of cables used in networks:
Unshielded Twisted Pair (UTP) Cable
Shielded Twisted Pair (STP) Cable
Fiber Optic Cable
• Security systems
Internet security is a branch of computer security specifically related to the Internet. Its objective is to establish rules and measures to use against attacks over the Internet. The Internet represents an insecure channel for exchanging information leading to a high risk of intrusion or fraud, such as phishing. Different methods have been used to protect the transfer of data, including encryption.
TCP/IP can be made secure with the help of cryptographic methods and protocols that have been developed for securing communications on the Internet. These protocols include SSL and TLS for web traffic, PGP for email, and IPsec for the network layer security.
A firewall controls access between networks. It generally consists of gateways and filters which vary from one firewall to another. Firewalls also screen network traffic and are able to block traffic that is dangerous. Firewalls act as the intermediate server between SMTP and HTTP connections.
