Building Management System
One of the major benefits of the direct digital control system within an airport (which covers vast areas and contains many different buildings and zones) is the availability of building data. The building management system (BMS) should have a project-specific graphical user interface to provide a complete overview of the entire system whenever required. Dynamic colour graphics allows for monitoring and operation of the system without specialist computer skills.
Another important function of a central BMS is to ensure a clear overall view and simple operation for the airport operators and staff. Alarm handling is particularly important; airport alarms are automatically registered, logged and routed to desired staff or peripherals (pagers, telephones, printers and management stations).
Once ‘archived’, the data listed above can be utilised in a number of different ways, merely as general archive information and records of building events and changes, to support design decisions or actively to promote new ideas and schemes:
Seasonal problem areas can be identified in order to anticipate before they happen (for example; if a particular part of a terminal building tended to overheat during the peak cooling season, the amount of chilled water serving that area could be adjusted).
Identification of plant performance can highlight problem areas, often reducing client maintenance costs or capital expenditure.
Building load profiles can be produced, allowing energy consumption records for cost allocation such as departmental, zone or tenant billing (for airport shops, on-site airport meeting rooms etc).
A detailed database of comparative analysis can be produced to look for variances which may indicate a problem. Comparison of an airports plant performance over consecutive years can identify efficiency losses, comparison of several terminal buildings can establish whether any are substantially less efficient than others.
