14 Case study of Wanke Centre green building 2

The green building technologies used in Wanke Centre include many aspects. First and foremost, in the interior of the building, water saving tools and methods are used to save water, such as low-flow toilets, waterless urinals, low-flow faucets with automatic control systems, and low-flow shower heads. Water-saving is at least 30% or more. A comprehensive rainwater recovery system was installed to collect the rainwater, accumulate it in the waterscape pool, and return it for greening and replenishing the loss of water from the landscaped pool.

As an office building, the design uses a large area of glass to get ample sunlight. However, in order to avoid excessive heat gain from the sun due to this design, and glare in winter, the design uses commonly used low-emissivity and high-transmittance glass, together with innovative, self-adjusting external shading system, which automatically adjusts the horizontal sun visor according to the solar elevation angle and indoor illumination.

In addition, solar hot water and photovoltaic power systems are important manifestations of solar energy in the building. Building photovoltaic systems produce pollution-free electrical power while beautifying the building image. In this project, solar energy is expected to generate 250,000 kilowatt-hours of electricity annually. Solar hot water is used for pool hot water and building showers for hand washing purposes. To promote the use of solar energy in office buildings. Last but not least, in the Vanke Centre's design, the office floor designed a special smoking room and an accompanying smoke exhaust system to control the flue gas well and ensure that the indoor environment has good air quality. At the same time, the amount of ventilation during office design has also increased 30%, to ensure the fresh indoor air. Furthermore, indoor decoration, strict selection of low-level radioactive materials include low VOC sealants, adhesives, carpets and other substances.
