1 SHUM YIP UpperHills LOFT Location: Shenzhen, China Date: 2018 Architect: Urbanus Solution and technologies: Envelope Introduction The Shum Yip UpperHills Loft, a Urbanus project, is a high-end commercial complex with 6 high-rise towers containing offices, hotels and business apartments. Adjacent to the CBD and Huaqiangbei shopping district, it is also located between two center parks in Shenzhen. 2 Description Located at the interchange of Sungang Road and Huanggang Road, Futian District, Shenzen city, China, Shumyip project is one of the 20 biggest projects to celebrate the 30th anniversary of the establishment of Shenzhen Special Economic Zone. The total construction floors are about 1.2 million m2. The project targets to be the top city complex in Asia and includes shopping street, mall, research office, LOFT, luxury hotel etc. 13.400 m2. Ductal® Envelope panels were used in the façade of LOFT. Application Shumyip project is a one of the key project with high attentions; owner would like to find a solution with high quality and durability, especially considering the impact of climate as coastal city. Secondly, the façade panels require double skin finishing, Ductal® has very good fluidity, which allows it to be casted in closed mould, and achieve high level surface finishing quality. Thirdly, the façade is designed as grill, with a 50% perforate ratio, with 20 mm thickness of the panel frame. Comparing with the traditional concrete or GRC solution, Ductal® can easily achieve the designed perforate ratio, no need for rebar or string to reinforce. Challenge At the beginning stage, the project owner explored many solutions, and also tried to get visual mock-up from several GRC manufacture. However, almost all the other mock-up was broken even during transportation. Hence, it was an opportunity to present Ductal® Envelope solution, and owner was attracted by the performance immediately. Ductal® team proceed with mock-up, engineering study supported by C&E, and expert review. Ductal® UHPC was finally selected for the façade ma- terial. 3 Optimization Ductal® has very good fluidity, which allows it to reflect the mould shape and achieve very high qual- ity surface finishing. Less water consumption reduces the material porosity and improves its dura- bility. Comparing with traditional concrete solution, Ductal® panel do not need reinforced strings, hence it can achieve very high perforated ratio, and also save labour cost and production time.
