Owner approach of sustainability

1) the ecological environment to meet the characteristics of the surrounding environment to create: According to the project is located in the ecological park landscape on the spindle characteristics of the unique, taking into account the architectural form, the wind field optimization, site runoff control and building insulation performance and many other factors to design optimization. 2) unfavorable towards the building under the body passive energy-saving design strategy: the full use of the building body from the shade, the appropriate set of fixed louvers shade design; lighting skylight, partition window and guide light combination of lighting design; open curtain wall, Natural Ventilation Design with Reasonable Organization of Airway. 3) Make full use of the site resource conditions of the energy system optimization and coupling: the combination of the project surrounding resources and the characteristics of the construction load, put the buried pipe and surface water composite system to solve the annual demand for air conditioning energy. 4) Combining the characteristics of water resources and the characteristics of the site of the energy center, the paper puts forward the non-traditional water use scheme of "rainwater-river-water-greening" four-in-one with water features and greening, and reclaims the roof and green rain , And the use of landscape ponds, rivers and other water reserves to achieve comprehensive utilization of water resources.

Architectural description

The green building design process of the project takes full account of the regional suitability, abandons the concept of technology piling, puts the passive building design in the first place, through the building shape, the shape, the overall layout, the facade design and so on the aspect, uses the climate suitability Environmental protection, natural ventilation, building shade and other green technical measures, coupled with the calculation of simulation technology to determine the best design parameters, saving resources and enhance indoor comfort. The main technical problems to be solved include: (1) to optimize the design of building size, function layout and external window to ensure the indoor with good natural lighting and ventilation effect, to improve indoor comfort. (2) in the appropriate area arranged light guide, to improve the slope under the lecture hall and the cold room natural light environment. (3) combined with rooftop roofing roof greening, effective combination with park greening. (4) the use of the southern side of the artificial lake conditions, the use of buried pipe and surface water composite energy supply system to meet the building air conditioning system with cold heat demand. (5) combined with the landscape water system and river to the rainwater storage, and the use of ecological treatment of the way the rain will be used.

If you had to do it again?

Chongming Chen Jiazhen energy center to overcome the main problem is unfavorable towards the building body passive energy-saving design, the solution has three points: 1) make full use of the building body from the shade, the appropriate set of fixed louver shade design. In view of the unfavorable orientation of the building, the self-shading of the glass curtain wall can be reduced by 43.73% of the radiation in the west, using the east and west 8.1m high slope and the second floor construction. At the same time in the two East and West external walls of perforated aluminum curtain wall on the whole facade shade, significantly reduce the construction load. On this basis, according to the shade analysis, in the need for shade of the second floor of the south side of the glass curtain wall outside the installation of a small amount of fixed horizontal metal louvers to add shade, so that the whole building in summer solar radiation are controlled at a low level. 2) lighting skylight, partition window hole and light guide combination of lighting optimization design. According to the functional nature of the building, in order to prevent glare, the east and west to only set the short window and narrow vertical bar and use the perforated aluminum plate to block; to improve the lighting effect in the exhibition hall and the middle of the top of the ramp to add light skylight; Optimization, the walls on both sides of the wall to open the wall hole, to enhance the central skylight on the two-story indirect lighting effect. 3) open curtain wall, transit window and wind towel reasonable structure of the natural ventilation ventilation design. The use of east and west sides of the wall of the window and the vertical structure of the ventilation window, the outer perforation of the curtain wall for the open; north and south sides set up landing window, you can open all the ventilation; the top of the axis set the wind skylight, Up and down the slope of the connection, so that the air up and down through.

Building users opinion

The project is integrated with a number of factors to optimize, the building is very comfortable to use. Construction of the east and west sides of the multi-purpose hall, calligraphy room and the west side of the engine room at the top of the natural pile slope, blocking the winter cold wind, guide the summer monsoon into the room, to avoid the problem of sun drying. Large area of ​​pervious ground, rain will not water. Although the building is facing unfavorable, but because of the use of soil slope, glass curtain wall, fixed louvers, shade effect is very good. Lighting skylight, partition wall hole and guide tube combination design, making the lighting effect to achieve the desired. Reasonable organization of the natural ventilation ventilation design makes the building internal ventilation effect is good. The building uses a lot of energy efficient measures, such as efficient exhaust heat recovery technology and air conditioning energy saving technology, indoor carbon dioxide monitoring and regulation, energy saving effect is remarkable.
