Lightwall

■Outline・A system to bring natural light into the hangar by

using polycarbonate with high light permeability for the wall

■Effects・To cut CO2 emissions by 159 tons a year

by combining its use with top lighting・Compared to glass windows, it has higher

insulation efficiency.

Toplighting

■Outline・A system to bring natural light into the hangar.

Used together with the light wall, it keeps the illumination level at the center of the hangar to 3000lx. During the daytime, no artificial light is needed to conduct maintenance work.■Effect・To cut CO2 emissions by 159 tons a year through

combined use with the light wall.・During the day, no artificial light is needed to

conduct maintenance work.

Gardenroof

■Outline・Green roof using light soil with high water-

retention properties■Effect・To reduce the air conditioning load through heat

insulation.・To improve the rooftop scenery and create a

place to relax.

Solarwater-heating system

■Outline・A water heating system that utilizes clean solar heat■Effects・To reduce the volume of electricity and gas used to

heat water

Use of rainwater to wash fuselages

■Outline・A system to reduce the volume of mains water

used by using rain water to wash fuselages and toilet flush

■Effect・To drastically cut use of mains

water.・The quality of rain water can be

improved to the level of mains water via a filtration system

Naturallybalanced wind-powervent window

■Outline・Effective ventilation system using pressure

difference and temperature difference to open/close the vent windows and create wind passage in order to ventilate efficiently.

■Effect・Possible to ventilate without using power・Allows around-the-clock ventilation.

NARITA INTERNATIONAL AIRPORT in JapanEnvironment-Friendly Hangar

The hangar incorporates a range of environment-friendly measures. The hangar has been designed to let in as much natural light as possible. Other eco futures include an advanced automatic ventilation system, fuselage washing devise that uses rainwater, and a garden roof. These energy saving and other eco features will reduce annual CO2 emissions from the figure of 900 tons for conventional hangars by 30% to 620 tons.

Line Maintenance Hangar Plan/Cross Section Facility Outline

This hangar is a facility to undertake maintenance on NCA’ s aircraft. A-checks are performed approximately every 1.5 months, as well as repairs between flights, replacing large parts, and washing fuselage/engines.

The hangar can hold a Boeing 747-400F or Boeing 747-8F which will be introduced into NCA’ s fleet in the near future. Moreover, this facility includes a 4-s tory annex bui lding where maintenance engineers and staff can undertake their tasks .

The hangar is a “luminous hangar,” which is environmentally friendly and maintenance staff friendly.

■Facility Features

Due to the special characteristic of the international air cargo business, our flights arrive during the morning and depart at night. Therefore, maintenance of our aircraft is normally undertaken during day time .

■Maintenance Work Features

Engineer ing & Maintenance cons is t s of Maintenance Planning, Engineering & Assurance, and Line Maintenance. Our site has obtained the Approval of “AMA”(Aircraft Maintenance or Alteration) and “AMI”(Aircraft Maintenance and Inspection) from the Japan Civil Aviation Bureau.
