How to ventilate the water cube?

The empty compartment between the two air pillows of the "Water Cube" is closed, which also forms an insulation unit. Ventilation is also a way to solve the heat dissipation problem. At the bottom of the periphery of the swimming center, there is a louver vent with a height of more than one meter, which can connect the inside and outside, and exhaust heat through ventilation to cool down. The above measures are mainly aimed at summer. In summer, the policy of heat insulation is "no insulation outside", but in winter, it is just the opposite. In winter, the louver vents will also be closed to ensure the indoor temperature.

Hundreds of millions of plating spots with different densities are plated on the inner membrane of the outer air cushion and the outer membrane of the inner air cushion of the "Water Cube" to control the light transmittance of the membrane and solve the problem of direct sunlight, thus reducing the heat brought by sunlight and not making the indoor temperature too high.

Founder, the Chinese designer of the Water Cube and the chief engineer of China Construction International (Shenzhen) Design Consulting Co., Ltd., explained that the indoor environment of the Water Cube fully considered the needs of athletes and spectators. The national swimming center competition hall and swimming pool all adopt louver natural air intake and mechanical air exhaust from the upper part, which can replace the forced fresh air volume. From the beginning of the construction, the health of the venue was monitored throughout the whole process. In this way, the wind pressure and pulsation of the structure and the change of temperature field can be truly recorded and analyzed, so as to ensure that the indoor environment is warm in winter and cool in summer.
