German Centre Taicang has been awarded DGNB and LEED GOLD Certification for interior fit-out buildings and has now officially received both certificates. The project was accompanied by energydesign (Shanghai) Co., Ltd. (CCSBC Partner) as DGNB and LEED consultants together. The interior fit-out concept was drafted by in50 Design, while an advanced energy concept was developed and implemented by energydesign.
German Centre Taicang (GCT) is the first DGNB certified interior fit-out building in China and continues the ongoing development of DGNB with a rather new DGNB scheme. The investment adds up to around 80 million RMB for the 3,985 m2 large project.
German Centre Taicang consists of currently three floors. Two additional floors are currently under fit-out. It functions as a cluster for German companies and offers different office concepts for corporate and individual purposes. The 12th floor hosts a café with seating possibilities and fresh German-baked bread as well as a green recreation zone. The GCT also features conference and meeting rooms, which can be used by all tenants for meetings and events. Moreover, an atrium with an open stairway and a vertical green wall between the 12th and 13th floor was designed, which also provides an informal “calm” area on the upper floors.
DGNB GOLD and LEED GOLD both represent the quality and efforts which have been put into this project and once again proof that both certification systems in combination can lead to a high-quality building environment. With support by DGNB and LEED, several qualities could be assured and delivered throughout the entire project, which could have been difficult to achieve without the structural framework that sustainable building certificates offer. The commitment and ambition of the client, as well as the motivation of all project stakeholders made it possible to deliver one of the healthiest and advanced office buildings in China.
Environmental qualities have been especially considered, as interior fit-out materials and its impacts on the work environment are crucial. Furniture, decorative paints or adhesives for flooring systems have high impacts on so called VOC- (Volatile Organic Compounds) and formaldehyde emissions. These substances can have negative impacts on building users’ health, concentration, and work performance.
A thorough strategy of domestic and imported high quality products with German quality labels such as “Blauer Engel” and “EMICODE” have been used for the interior. A constant follow-up by energydesign on material selection during the planning and design phase, as well as on-site commissioning during construction has been conducted. The furniture has been selected together with German and international suppliers, following the approach of low-emission, modularity, ergonomics, as well as ease-of-use and cleaning friendliness.
Special attention was also put on the fresh air system, specifically designed and sized for the floors of the German Centre within the building. Among increased ducting and fresh air capacities, the system contains a MERV15 filter system, which allows filtering up to 95% of PM2.5, which altogether ensures the highest air quality possible inside the building.
In addition to air quality measures, visual comfort of users was of high value for the client as they are essential to ensure high-quality work environments. energydesign worked out an artificial-/daylight concept, including daylight/occupancy-controlled Philips LED luminaries and an integrated shading system. Both systems are connected to the so-called DALI control system, which allows flexible control patterns and easy operation of different system functions in one control panel.
An overall flexible design of the building systems and the interior allows tenants to arrange their office space according to their immediate needs. This also reflects to the purpose of sustainable buildings and has been regarded highly by DGNB in terms of Life-Cycle Costs and economic qualities.
To ensure the ease of use for technical systems such as HVAC or lighting controls, a tenant handbook has been prepared together with the German Centre Taicang. This handbook also includes requirements and suggestions for the tenant’s own office fit-out, regarding decoration materials and furniture. To increase energy efficiency of tenant’s periphery such as printers, screens or computers, recommendations using Energy Star and China Energy Label Class I + II certified products have been made.
为了让租户方便使用空调及照明系统，设能公司准备了租户使用手册。手册同时还包括了对租户自行装修办公室所使用材料和家具的要求及建议。为了提高租户办公设施的能源效率，如打印机、屏幕或电脑，推荐使用“能源之星”和中国能效标识“I + II”级认证产品。
DGNB and LEED both are highly sophisticated and advanced green building rating systems which however differ in the way how to assess the quality of a building and its environment. DGNB focuses on the entire life-cycle of a building, but especially on the well-being of the users. The DGNB system does not assess individual measures but instead the overall performance of a building and works as a management tool from the early beginning to the end of a project. This means that also process qualities, such as the planning/design and operation process are equally considered. LEED as the most popular green building certification program worldwide certifies a building based on the categories sustainable sites, water efficiency, energy & atmosphere, materials & resources, indoor environmental quality and innovation in operations & regional priority. Based on the performance of each category, the final score is assessed.
