Double skin's "Lemon" | |
|
Why does the lemon have a very thick skin? This building is called the 'Lemon' due to its characteristic shape. A trunk road runs at the west side of it, where one cannot avoid the exhaust gases and noise of passing vehicles. The building sits on a site, which had deterred construction of any kind. Therefore, the challenge to the architects was how to fight off the noise. They subsequently adopted a double skin design. Double skin in the West, granite-like appearance in the East The entire surface of the western wall of the Lemon is covered with tempered glass (12-15 mm thick, u-value 5.4W/m2K, 72% g-factor, 83% τ-value) and inwardly at a distance of 70 cm lie the sliding-door sashes which are fitted with Low-E double glazing of u-value 2.1W/m2K, 62% g-factor, 83% inτ-value, 32dB for sound insulation. In the upper part of the double skin runs an air duct for mechanical ventilation; intake of fresh air from the suction ports on the northern and southern parts of the roof; emitting from the roof again. In order to cut off the intense sunlight of the summer, roll-blinds are installed close to the outer facade. This double skin structure works well to insulate noise. In the eastern side, the facade is entirely covered with glass-curtain-walls (u-value 1.7W/m2K, 38% g-factor, 50% τ-value, 44dB for sound insulation). The glasses, however, are screen-printed at the part near the spandrel and the staircase, so they look exactly like granite.
