Owner approach of sustainability

Following the principle of “passive design takes priority, and active design makes optimization”, various green building technical measures were tailored to local condition in this project, such as BIM and low-impact-development, and sustainable design was combined with engineering design to achieve the goal of “healthy, low carbon, and environmentally friendly”. The operation energy consumption of this project is around 53.67 Kwh/m2/year, which has an energy-saving rate of 65%, comparing with ordinary office building in cold climate zone of China.

Passive design takes priority: building spaces, wind environment, light environment, and thermal environment were optimized through software simulation, for instance, the basement get natural daylighting through light wells and light tubes, while the wall inlets were applied to strengthen natural ventilation; rainwater garden, permeable pavement, and water storage module were adopted for low-impact-development’s rainwater management; energy dissipation structure system saved concrete consumption of 1350m3, which reduced about 49 tons of carbon emission; and recycling material utilization rate was 10.3%; moreover, the reasonable overall plan layout provided suitable site for ground source heat pump’s pipe burying, while protecting more than 50 existing trees on site.

Active design makes optimization: The project minimizes fossil energy consumption through multi renewable energy complementary application, major system includes ground source heat pump, parabolic solar collector, lithium bromide absorption type cold water unit, ammonia absorption air source heat pump, solution conditioning humidifier, DC brushless fan coil. In terms of electric and intelligent design, the building intelligent platform integrated all MEP systems such as intelligent lighting, elevator control, intelligent power diagnosis and recovery, and photovoltaic power generation. Furthermore, various measures were taken to improve indoor environment, such as the fresh air system that responses to CO2  sensors, and intelligent shading control system which has flexible sunshade opening and angle control under different sunshine conditions.

Architectural description

1. Fusion of healthy and green building technology

As a typical office building for a design institution, major users are professional architects and engineers. The users’ daily work is characterized by high work intensity, which usually causes cervical spondylosis, stress, irritability, less communication and other health problems. For designers who are engaged in creative brain work, the office environment is more demanding for health and comfort. From the perspective of “user-oriented”, our solution is to build four special healthy spaces: comfortable office space, fitness space, health management space, and recreational space. Firstly, adopted a variety of healthy green technical measures such as intelligent exterior shading, vertical planting, direct drinking water purification mineralization system, solution conditioning humidifier fresh air system, ground source heat pump system, etc. to create high-performance green office Space. At the same time, we set up a complete sports and fitness, health management, leisure and entertainment space, such as gymnasium, diagnostic room, yoga room, etc., and optimize the operation management system, regularly organize sports activities, and carry out group activities such as calligraphy, chorus, photography, etc. By delivering healthy knowledge and encouraging building users to join various activities, TADI efficiently promotes the overall health of employees at the physiological, psychological and social levels.

2. Environmental friendly, low carbon emission

The overall color and architectural style of the project is coordinated with the existing administrative office building which was built in 1995 on the west side. At the beginning of project planning, the building was laid out from the perspective of site ecological protection. While retaining more than 50 tall trees, it also inherited the 67 years of historical memory and emotional linkage of TADI’s current employee. The landscape design of the new building focuses on ecology and humanity. The beautiful garden space not only provides designers with a comfortable and relaxing space for recreation, but also provides habitat for birds and small animals, which balance a harmonious coexistence between man and nature.

While improving the physical and mental health of building users in all aspects, the project also focuses on green and low carbon technologies. Based on local climate and site conditions, ground source heat pump coupled with solar heating and cooling system is adopted to maximize usage of renewable energy, while cooperated with other green building technical measures to reduce operating energy consumption to 53.67Kwh/m2/year, and created a healthy and green office building.

If you had to do it again?

In the stage of independent research and development of intelligent system, this project encountered the problem, interfaces were unable to be developed in some of the system, and of own system data were unable to be provided to the integrated platform, such as elevator monitoring system and air conditioning automatic control system. By writing specific interfaces requirements into the bidding documents, clearly requiring that specific interface types shall be provided in systems and the interface test shall be carried out before the bidding, only the product passed the test can be used for the bidding. By conducting the Project coordination meeting regularly to solve problems in the debugging stage, the R&D team had successfully solved the problem, ensuring normal operation of the intelligent system.

    (2)Design of indoor and outdoor shading: Considering the demand of heating in winter and shading in summer, as well as the lighting effect of main functional space, this Project optimizes the building shading design from the scheme stage. The self-shading of the wall is enhanced by appropriately deepening the depth of the window. Meanwhile, in the Project, the hidden adjustable shutters to shade are mounted on outside windows in east and west, and irradiance and wind speed sensors are set on the tenth-storey roof to control the curtain status according to the real-time data of small meteorological stations. According to the demand of light and heat in different seasons, automatic control can set up various modes to effectively reduce the energy consumption of lighting and air conditioning. For outside shading, automatic protection device is used, when the outdoor wind speed is 24≥ m/s (i.e. strong gale), the curtain will be automatically retracted to ensure safety. In the Project, the external shading adjustment terminal and adjustable inner shutter shading are set to facilitate users to adjust indoor lighting and thermal comfort more flexibly.
