2、绿色设计理念

西太湖之“星”来自于绿色设计的理念，通过对建筑形体的多次切割，达到对自然光照的最合理利用，同时形成“钻石”的切面形体。建筑形体与水岸绿带相契合，与山水景观进行充分对话，成为湖滨绿带中的重要景致，同时又是一个三百六十度的全景建筑。

 

2. Green design concept

The "Star" of West Taihu Lake comes from the concept of green design. Through multiple cutting of the building shape, the most reasonable use of natural light is achieved, and the cut shape of "diamond" is formed at the same time. The architectural form is consistent with the waterfront green belt, and has a full dialogue with the landscape. It has become an important scenery in the lakeside green belt, and it is also a 360 degree panoramic building.

 

本次设计对建筑的绿色理念进行了全面探讨，不仅从视觉上拥抱自然，同时把可持续的低碳理念贯穿设计始终，最大化利用自然光照与自然通风，减少碳排放。从空间角度而言，绿色被引入到建筑内部当中，保持了城市绿带的连续，又赋予内部空间新的可能性，为使用者创造出高质量的体验。

 

This design comprehensively discusses the green concept of the building, which not only embraces nature visually, but also runs through the design with the concept of sustainable low-carbon, maximizes the use of natural light and natural ventilation, and reduces carbon emissions. From the perspective of space, green is introduced into the interior of the building, maintaining the continuity of the urban green belt, giving new possibilities to the internal space, and creating a high-quality experience for users.
