Attractiveness :

​1.Overall layout and wind environment optimizationArrange the building along the axis of landscape layout. The natural slope is arranged at the top of the multi-purpose halls on the east and west sides, the calligraphy room and the machine room on the west side, which can decrease the effect of building on the environment, play a guiding role to tourists, resist the winter wind as well as lead the summer wind into the interior.
2.Large greening and permeable ground setting for rainwater storage and regulationSet large complex layers of green, and set the pervious concrete, porous asphalt and permeable adhesive stone pavement, so that rainwater can be fully infiltrated and stored. The total proportion of outdoor permeable ground area is 95.6%

3. Utilize the roof greening of the site slopesThe roof greening slope area is 1230.8m2, accounting for 30.4% of the roof greening area, integrating the building and the surrounding park together. It is conducive to adjusting micro climate and enhancing the insulation performance of the roof.

4. Utilize building body for shadingFirst use the 8.1m high side slope on the east and west side and the overhang on the 2nd floor and the glass concave design to realize self-shading of the curtain walls , which can reduce 43.73% of the radiation on the west side.Set perforated aluminum curtains on the east and west walls on the 2nd floor for shading of the facade, which reduces cooling load significantly.

5. Optimization of the integrated skylights, windows and lighting tubesIn order to prevent glare , only short windows and narrow window bars with perforated aluminum blocks are set up in the exhibition.In order to improve the lighting effect, a skylight is added at the top of the exhibition hall and the middle ramp, and the lighting factor can be increased from 1.15% to 4.41%.

6.Natural ventilation designs of open curtain walls, transit skylights and ventilation towers Organize ventilation using the short windows and narrow window bars .Set the curtains open.Set open-close French windows on the south and north sides.Set ventilation towers on the top of the axis. Set slope for connection in the middle of the building so as to ventilate the hall.The building passive energy saving technology can provide enough indoor ventilation rate through several strength method of natural ventilation although the management center is east-south orientated and has 100m depth.The ventilation rates for 90% of the rooms are more than 5times/hour

 

Well Being :

Social Cohesion :

​1.The optimization and coupling of the energy system with full use of the site resources provide experience for the design of other similar projects, which has good social and economic benefits 2.On the basis of the research results of green technology, 5 papers have been published in domestic core journals, playing a very good promotion effect.3.Saving 99.8MWh energy through the green design of this project. Saving 29.94 tons of standard coal. Reducing 104.8 tons of CO2 emissions.4.Realizing real-time energy monitoring, intelligent management and intelligent micro grid system in this building. green technology promotion and display play a very good role in promoting effect.5.Green technology such as park landscape features, flexible application of sloping roof greening, rainwater treatment, ecological pond, sprinkler irrigation system play a good green technical propaganda role to the visitors.6.The technical application of this project can provide guidance and demonstration for the green design of exhibition buildings, parks, supporting buildings and waterfront buildings

Preservation / Environmental Improvement : ​“Rain-River-Landscape-Greening” Integrated Unconventional Water Utilization Scheme According to the water source and field characteristics of the building location, the scheme reuses the rain from the roof and greening area and utilize the landscape, river, and water storage tank for achieving integrated utilization.1.River and landscape provide water storage and the greening provides penetration space for avoiding flooding.2.Landscape and greening provide rain water treatment for avoiding pollution.3.Rain water and river work as the irrigation source of the landscape and greening enhancing utilization for unconventional water source.4.Landscape and irrigation water usage is huge in this project. The unconventional water usage can reach 16441.45 m3/a , totally saving about RMB50900 per year.

Responsible use of resources :

​GSHP combining the ground pipe and surface water1.Propose ground pipe and surface water integrated GSHP system to meet the cooling and heating demand according to the around sources and building load characteristics. 2.The project adopts the measure for reducing the peak demand that utilize lake as heat tank based on the soil thermal balance in a year: the buried pipe heat exchanger takes 80% of the cooling load and the lake water heat exchanger takes 20% of the cooling load. The whole system saves 21.33% of total energy consumption annually.3.According to that there is requirement of living hot water, the ground source heat pump unit adopts the condensation heat recovery function. Part of condensing heat is recovered in summer for producing hot water which saves about 10,000 yuan.Building Integrated PV (BIPV) system1.The photovoltaic power generation system is arranged on the roof of which the total installed power is 178.56KWp. It uses 48 ECF-20A type 20% transmittancy film silicon solar panels with and 584 TSM-300 type polysilicon battery plate which is grid-connected on the user side.2.Optimize the arrangement of the solar photovoltaic system to ensure the efficiency of the photovoltaic system and prevent the occurrence of the hot spot effect and damage. Based on the influence of the roof component bulge in the middle part of the roof, the photovoltaic array is connected in series with the north and south.3.20% transparent silicon based thin film battery board. 4.Providing 35.8% of the annual electricity load.Energy and water saving efficiencyTotal energy consumption rate: 80.12kWh/(m2year)（without PV）,Total energy consumption rate: 51.4kWh/(m2year)（with PV）,PV providing 35.8% of the annual electricity load.Unconventional water source usage rate: 70.91%
