Solar Decathlon China 2018

Solar Decathlon China 2018 (SDC2018) is co-sponsored by the U.S. Department of Energy and China National Energy Administration, organized by China Overseas Development Association and supported by the School Department of the Central Committee of the Communist Youth League. 22 teams consisting of 41 schools from 10 countries and regions will be competing in Dezhou, Shandong Province in 2018.

Aiming for permanent usage, the competition requires teams to build a single- or two-story solar house with a finished area of 120-200m2 and equipped with all necessary household appliances such as TV, refrigerator, cooktop, dishwasher, washing machine, and computer. In addition, each house shall have an electric vehicle and its matched charging device. Teams will compete in the following ten contests.

 

Team JIA+ Project

      Design Philosophy

For the competition, the team JIA will present its architectural and urban planning project in China: JIA +. The rural exodus and a brutal urban renewal policy brought the destruction of many traditional villages(more than 1 millions in ten years–300/day). We propose to try to find a new way to densify the city sparingly by. building a new house, the « JIA + house », in the courtyard of a renovated traditional house. By building a second house on the same plot, we place the human at the heart of the project and new participative modes are proposed. Domestic tourism in China is in full development, we suggest that the renovated traditional house becomes a guesthouse for tourist and that the JIA + house become the new home of the inhabitants sometimes multigenerational families, or vice versa. The renovation of the old house can be revaluated by the exploitation of the second, which makes financially feasible the implementation of our concept. The bioclimatic design that we propose uses wind, water and sun as privileged energies. Respectful of the environment, our concept promotes the use of local and natural materials (wood, straw, bamboo) while participating in the protection and enhancement of heritage.

 

     International concept

The JIA+ project comes from the international exchanges of the Franco-Chinese team and results from the work carried out by the Team Solar Bretagne in France around the TY + TY concept and especially the re-thinking of this scheme on the Chinese and local context by the relationship between teams and disciplines.

     Prefabrication and Fabrication

An eco-responsible house has to be built quickly with a dry and healthy construction process. The team works on a modular solution to optimize the assembly time through simple and accessible construction modes. The wet blocks are bundled with integrated networks to prevent plumbing on site. The rest of the walls is a 2D caisson system consisting of reconstituted beams with small sections of wood. Thus, even untrained students or novices can take over the system and participate in the construction.

     90% Eco-materials

Always in a logic of sobriety, we chose biosourced materials, resulting from the biomass, for an architecture respectful of the environment. Carbon traps, they contribute in the need to improve air quality in China. We made the choice of straw board insulation because this material is available in large quantities in Shandong, humidity regulator and inexpensive. Finally, the box beam structure of small sections saves material and resources.

     Bioclimatic and energetic strategy: Sobriety and efficiency

The team’s driving line is « the best energy is the one you do not consume ». By following values of energy sobriety, we first favor the use of the « free » that are the sun, wind and water in a passive design. That’s what led us to define the silhouette of our home: a bioclimatic design to make the most of all these natural elements. The open shed to the north side of the roof provides natural indoor ventilation and continuous diffused lighting in the living areas. A summer garden with modular and adjustable architectural surface provides sun protection for facades exposed in summer.

2018中国国际太阳能十项全能竞赛

2018中国国际太阳能十项全能竞赛(简称SDC2018)由中国国家能源局和美国能源部联合主办,中国产业海外发展协会承办,共青团中央学校部为支持单位,邀请了来自全球10个国家和地区41所高校的22支赛队参与,将于2018年在山东省德州市举办。
大赛要求每支赛队以永久性使用为目标,建造一栋完成面积为120-200平方米的单层或双层太阳能住宅。房屋必须配备电视机、冰箱、烹饪厨具、洗碗机、洗衣机、电脑等日常家用电器及生活设施,并新增电动汽车及其充电设备。竞赛将通过以下十个单项来评比最终成绩。

 

 

家+队

     设计理念

在这次竞赛中,家+团队将城市规划和建筑设计概念通过“家与家”的形式展现。随着快速的城市化进程和随之而来的传统村庄的大量消失,我们希望通过在一座老房子的院子里建造一栋新房子来重新诠释老房子的价值从而探索解决拥挤的城市中居住舒适性的问题。在新建过程中,我们以建筑的使用主体——人为项目的核心,同时提倡参与式的建造。此外,在中国旅游业快速上升的背景下,我们希望将改造后的传统建筑作为面向游客的民宿,新房子作为本地居民几代人的家,亦可反之。更新后的老建筑将随着新建筑的使用而提升价值,和也就使得此项目的经济价值及其可行性显而易见。基于气候适应性的设计包括对于风、水和阳光等自然要素的利用,体现出JIA+项目在本着参与保护历史建筑遗产的同时,更加注重对于当地环境及其自然材料如木材、稻草、竹子等的充分利用。

 

     国际理念

JIA+项目基于中法团队的国际合作,亦来源于Team Solar Bretagne在法国的概念TY + TY,尤其是在多团队与跨学科的基础上,在中国的地域文脉中重新诠释这个设计理念。

 

     预制与装配

真正生态的房屋,是应快速建好的,并在一个无湿作业和无能耗的建造过程下完成。JIA+团队致力于通过简单易懂的建造模式来提升装配效率从而探索出一种模数化的解决方案。湿区模块相互连接为一个整体以保护场地受到水的影响。其他墙体形成二维模块系统,由小块木材组成的组合梁组成。因此,即使未经训练的学生或初学者也能掌握和学习这套系统并参与到施工过程。

 

     90%的天然材料

基于适度和尊重自然的原则,我们选择有机的天然材料作为建筑材料。碳回收与利用,提升了中国的空气质量。在山东有很多稻草资源,因此我们选择了稻草板这一低成本而具有空气调节器作用的材料作为保温隔热材料。最后,由小模块组成的箱型梁结构既节省了材料也节省了资源。

 

     基于气候适应性和能耗策略:适度与效率

团队的目标是“最好的能源就是你从不消耗能源”。在节约能源的原则下,我们首先选择将免费能源如阳光、风和水,应用到被动式设计中,从而勾画出家的轮廓:基于气候适应性的设计,使得绝大部分元素都是自然的。北侧屋顶的天窗为客厅提供了自然通风和连续的漫射光。模块化的夏季花园,通过可变表皮为建筑立面提供遮阳,从而保护构件在夏季不受日照的损坏。
