可变体形系数太阳能住宅的研究——中国国际太阳能十项全能竞赛
|
摘要
绿色能源建筑科技竞赛要求每支参赛队建造一栋地面投影面积120～200m2的双层太阳能住宅,供单一家庭使用。同济大学与德国达姆施塔特理工大学作为战略合作伙伴参加竞赛。该研究利用体形系数在建筑节能上的影响,找出最小体型系数形态的同时,也寻找尽可能大的体形系数形体。把二者结合在一个建筑中,通过智能变化让建筑适应季节变化和各种天气变化,达到最低能耗最高产能、能量收支平衡的状态。通过材料与结构的选择、主动节能设计和被动节能设计的相互渗透,运用空间改变法中的中庭与建筑结合的做法,设计建造一栋能永久使用,并完全由太阳能提供满足日常生活所需的能源房屋。可变体形系数太阳能住宅因其灵活多变、绿色节能,应用前景广阔。
Green energy construction technology competition requires each team to build a double floor solar house with a projected floor area of 120～200 square meters, which is used by a single family. Tongji University and Darmstadt Polytechnic University, Germany, participate in the competition as strategic partners. In this study, the influence of body shape coefficient on building energy efficiency is investigated. At the same time, the minimum shape coefficient shape is found, and the largest shape coefficient shape is also sought. Combining those two shapes in one building through artificial changes, the building can adapt to seasonal changes and various weather changes and achieve the lowest energy consumption, maximum capacity, energy balance of payments. Through the selection of structure and material, mutual penetration of active energy-saving design and passive energy-saving design, the practice of using space in the building and changing the atrium, to design and construct a permanent use house which is fully supplied by solar energy. Because of its flexibility and green energy saving, the solar house with variable figure coefficient has broad application prospects.
