Nearly Zero Energy Building of the Gui'an Innovation Park is the first demonstrating and experimental Nearly Zero Energy Building of the Gui'an Innovation Park in southwest China, which locates in the park's entrance and connects with the constant ecological sponge city landscape, providing an extremely fascinating scenery for both users and visitors. Moreover, its two floors above ground can serve as large-space exhibition, VIP reception & conference and daily office, while the one single underground floor can act as the equipment and storage area.
Nearly Zero Energy Building of the Gui'an Innovation Park is both a practical demonstration case which deeply integrates sustainable design strategies with ecological technologies, and an experimental platform for sustainable architecture based on the Moderate Zone in southwest China, aiming to examine whether the detailed design methods and building technologies can truly suit to the local conditions of climate, culture and even economy. Oriented to the specific project positioning, the design team has developed the multi-system integrated design strategy with the sustainable passive design methods from the very early design phase to minimize the negative impacts to local ecological system while maximizing the indoor comfort and energy efficiency.
The double-skin façades consisting of double-glazed façade at the first floor and the rattan-weaving double skin at the second floor are typical climate responsive design. The double-glazed façade compasses three components: external single-glazed skin, intermediate air cavity and internal high-performance facade, which can adapt to the seasonal changes of outdoor environment through different operative modes of the vents and windows to reach the expected thermal and ventilation performance. Four module patterns of the rattan-weaving double skin are also developed and arranged according to local solar radiation and wind pressure on each façade through software simulation, aiming to comprehensively integrate environmental performance, structural stability and material durability together.
The building also adopts the underground air through tunnel as the passive air-conditioning system, which can largely reduce the energy consumption particularly in summer and winter. Its vertical venting ducts are further integrated in the air cavity of double-skin façade and distributed into the major working places, providing fresh air while creating indoor comfort.
The landscape is based on the native plants of the region, and all the paving is permeable to water. Application of Integrated ecological purification system for roof rainwater is used , and the water is for the landscape pond on the south of the building.
The passive sustainable design methods responding to local climatic factors of natural wind, solar radiation and daylight are further contrived by the design team. Firstly, the two-floor height central exhibition hall with extra-raised ventilating skylights can truly act as venting chimney to promote both wind and thermal pressure ventilations while providing adequate and colorful light for the interior. Secondly, the double-skin façades consisting of double-glazed façade at the first floor and the rattan-weaving double skin at the second floor are typical climate responsive design. The double-glazed façade compasses three components: external single-glazed skin, intermediate air cavity and internal high-performance facade, which can adapt to the seasonal changes of outdoor environment through different operative modes of the vents and windows to reach the expected thermal and ventilation performance. Four module patterns of the rattan-weaving double skin are also developed and arranged according to local solar radiation and wind pressure on each façade through software simulation, aiming to comprehensively integrate environmental performance, structural stability and material durability together. Thirdly, the building also adopts the underground air through tunnel as the passive air-conditioning system, which can largely reduce the energy consumption particularly in summer and winter. Its vertical venting ducts are further integrated in the air cavity of double-skin façade and distributed into the major working places, providing fresh air while creating indoor comfort. Fourthly, the building highly encourages usage of renewable materials such as timber, steel and wheat-straw board and promote the employment of vernacular materials and craftsmanship such as traditional rattan-weaving, blue-stone floor pavage and rubble wall masonry, which can both decrease the carbon footprint during whole life span and create a unique architectural self-expression.
