Lighting engineering of Dublin Airport terminal 2

Arup and Pascall&Watson architects, designed at Dublin Airport 2 new terminal, about 100 thousand m2. November 13, 2010 officially opened to the public, which marks the thirteenth largest airport in Europe to contribute to the international transport of their own power. Arup's lighting team, appointed by the Dublin Airport authority (DAA) for the airport's internal and external daylight and electrical lighting design. In short, it is to provide the best international lighting standards for passengers and airport staff, while reducing energy consumption and maintenance costs. This project lighting strategy, mainly from the three components to reflect the quality of the building. Which is the most important departure and arrival. In the registration and departure ceiling height ranging from 10-20m, indoor space is lit by a point source array. The arrival route has a generally lower ceiling height and is suitable for introducing linear and compact fluorescent light sources. Ceiling lamps and other equipment are well integrated into the architectural style.

Custom designed metal halide lamps are grouped in the registration and departure areas with high ceilings to reduce maintenance and reduce visual confusion. But in the lower ceiling areas, such as the registration counter, compact fluorescent light source, provides environmental lighting. In order to maintain the visual clarity and maintenance convenience, the use of a color temperature through the whole building. Boarding corridor E consists of three levels: arrival and departure flow and lounge. The flow path of the use of lighting, continuous linear fluorescent lamps are installed on the top of the main service line. Lighting becomes a narrative tool to guide people's airport journey. Lighting can be used to enhance the sense of direction in the building, and highlight the linear form of the structure.

Sunlight enters the interior of the building, from the glass walls and roof skylights. The sun shading system is designed to reduce heat, but also selectively allow sunlight to penetrate only certain areas, so as not to cause discomfort to passengers. Intelligent lighting control system using the DALI protocol, and the natural skylight link. The lighting unit can be adjusted or switched to suit the conditions of field operation. High efficiency energy-saving light source, such as metal halide lamp, fluorescent lamp and LED, used to reduce energy consumption and improve bulb replacement time and service, can reduce maintenance costs. Regardless of daytime and electrical lighting to meet the design parameters, and can meet the purpose of use, easy maintenance, energy saving, efficient operation. The overall lighting design reduces the overall 17%CO2 emissions (compared with the code compatible design). The correct control of daylight and electrical lighting, can facilitate passengers at the airport to find a way to speed up the flow of people through a short, static space.

This lighting program has both functional and quality sense, can optimize the building, providing passengers with a calm and clear sense of airport traffic. Dublin Airport terminal 2 welcomed by the public. The new terminal is a beautiful modern building, it welcomes visitors to Ireland, but also enhance the ability to increase airport reception, the annual reception of 32 million visitors.
