Green building is a sustainable building concept that can provide economic, environmental, and social benefits. To achieve the goals to become a green company, our Hangar 4 has implemented an environmentally-friendly design concept, such as the use of skylight roofs and heat glass to maximize lighting, metal halide lamps, curtain walls made of laminated glass to maximize the circulation of light, alumunium grilles to minimize air turbulence, and the blunt shape at the corner of the roof to help drain the air.
