An advanced lighting management scheme, based on Eaton's MEM D-bus system, provides safe, energy-efficient lighting control in the new £60 million Ground Transport Interchange (GTI) and 4M office development at Manchester Airport.
The GTI, or ‘Station’, is the only airport interchange to bring together bus, coach, rail and, later, Metrolink tram services under one roof. The purpose is to increase the proportion of airport journeys made by public transport from 21% to 40% by the year 2015. By then the number of passengers will have risen from 20 million to 40 million per annum.
Eaton's MEM D-Bus system provides automatic daylight-linked lighting control in the Station and six-storey 83,000 sq ft offices. Since completion, Eaton's MEM has supplied additional control hardware and reconfigured the existing controls on four of the office floors to meet the needs of individual tenants as they moved into the offices.
A roof-mounted lux detector provides eight fully-programmable network outputs, some operating in conjunction with time events, to switch both functional and feature lighting automatically. This ensures that adequate lighting is maintained no matter the time of day or the prevailing weather conditions.
A system of 234 dimming PIR sensors, eight Floor Controllers and 166 Lighting Control Modules, that provide the final control interface to groups of luminaires, ensures that all areas are well and attractively lit at all times. Automatic dimming balances natural and artificial lighting for optimum energy efficiency and working conditions. PIR sensors in the offices sense the presence of personnel so that lighting only operates when required.
The sophisticated control system not only provides lighting in the immediate vicinity of anybody working in the building but also ensures that adjacent areas are lit and that lighting is provided along exit routes relevant to locations where people are working.
The control facilities for tenants include PIR or switch control of lighting, PIR control with switch override, or PIR control with daylight-linked automatic dimming.
D-bus is a fully-addressable, computer-based, distributed intelligence lighting control system incorporating Echelon Lonworks™ data protocol. It allows complete control, monitoring and configuration from a desktop or laptop PC. Eaton MEM also provided commissioning services for the Manchester D-Bus installation.
The overall project has been managed by Manchester Airport Developments, a division of the Manchester Airport Group (MAG). Architect was Aedas, building services engineer was Hoare Lea and the main contract for the fit-out was by John Sisk & Son. The lighting scheme was designed by Luxonic Lighting and installed by Rotary North West.
