江苏省绿色建筑博览园“木营造馆”的建筑设计

ARCHITECTURAL DESIGN OF “WOODEN PAVILION” IN JIANGSU GREEN BUILDING EXPO PARK

以江苏省绿色建筑博览园“木营造馆”为例,在建筑设计的各阶段以“被动式设计”为策略首选,因地制宜确定适用性绿色技术,并应用相关模拟软件对建筑节能设计各关键环节进行性能化模拟,从回应地域气候的绿色建筑设计、外围护结构节能设计、预制装配木结构技术三方面出发,探讨如何将绿色节能技术与现代木结构技术进行整合。应用相关软件对建筑室外风场、建筑朝向、室内空间环境、木结构外围护结构进行模拟分析,并从经济性角度优化了外墙和屋面保温材料的厚度。结果表明,合理的建筑朝向和功能空间组织、高性能木结构外围护结构、种植屋面、可调节外遮阳以及光伏一体化设计,可以有效降低建筑能耗,达到超低能耗建筑的节能目标。

Taking the “Wooden Pavilion” of Jiangsu Green Building Expo Park as an example, “passive design” was the preferred strategy in every stage of architectural design and the applicable green technique was determined according to local conditions. Incorporating passive energy-saving design into architectural creation, the performance simulation of building energy saving design was carried out by applying relevant software. The integration of green building design and modern timber structure techniques was discussed from the three aspects of green building design that responds to regional climate, energy-saving design of envelope structure and prefabricated timber structure techniques. The wind field outside the building, the building orientation, the indoor space environment and the external envelope enclosure of the timber structure were simulated and analyzed by using the relevant software. Meanwhile, the thickness of exterior wall and roof insulation materials was optimized from the perspective of economy. The results showed that reasonable building orientation and functional space organization, high-performance envelope enclosure of timber structure, planting roof, adjustable exterior shading as well as photovoltaic integrated design could effectively reduce building energy consumption and achieve the energy-saving goal of ultra-low energy consumption buildings.
