超薄、轻质等材料建造的房屋在救灾、建筑工地领域应用普遍,针对这类特殊建筑的温室效应现象虽有揭示,但局限于透光膜及玻璃房,对其冷室效应认识尚属空白。本文通过搭建外形尺寸相同、围护材料材质不同的超薄轻质围护结构模型建筑,在相同的室外条件下进行对比实验,发现无论夏天或冬天,在有太阳辐射的白天时刻,即使非透光的超薄轻质围护结构建筑的室内表面温度和气温均高于或远高于室外温度,温室效应的强度取决于室外气候条件和围护结构特性;在夜晚,室内表面温度和气温可能低于室外温度,超薄围护结构比轻质围护结构的冷室效应显著,晴朗夜晚比阴雨夜晚显著,并进一步揭示这类建筑的特殊热环境现象的共性规律和形成机理。 相似文献

If robots are to be employed in the construction of high-rise structures, logistics and material systems have to be entirely rethought to cater for both their abilities and limitations: robots have limited loading capacity, but greater dexterity than other on-site, automated construction techniques. Here, Norman Hack of ETH Zurich and Willi Viktor Lauer of the Future Cities Laboratory (FCL) at the Singapore-ETH Centre for Global Environmental Sustainability (SEC) describe the research they have undertaken to develop ‘mesh-mould’ as an alternative to conventional formwork. 相似文献

Remo Pedreschi 《Architectural Design》2008,78(2):12-19
Over the last century, engineers' and architect-engineers' approach to the relationship between form, force and mass has changed significantly, both on a conceptual and methodological level. It is a shift only made possible by the collaborative efforts of design, engineering and construction expertise. Professor Remo Pedreschi discusses the work of Robert Maillart, Pier Luigi Nervi, Eduardo Torroja, Felix Candela, Heinz Isler and Eladio Dieste to illustrate the important changes and contributions that have taken place and how they influence the way we think about performance from an engineering point of view today.

Cristiano Ceccato 《Architectural Design》2012,82(2):96-103
Free-form geometric designs make use of continuously differentiated components that exist within a multidimensional envelope of material performance, fabrication capabilities, logistics and cost. In this article, Cristiano Ceccato explains how geometric form-rationalisation and analysis of constructability at the functional as well as the computational level form the basis for achieving advanced designs in terms of articulation of material through mass-customised industrial production. Taking examples from the current work of Zaha Hadid Architects (ZHA), he presents a necessarily evolving framework of computational design and associated practice of architecture that is attempting to close the gaps between computational design, digitally controlled manufacturing and evolving mechanisms of contemporary construction and project delivery.

Shajay Bhooshan heads up the computation and design ZHACODE group at Zaha Hadid Architects (ZHA) and is a course master at the Architectural Association Design Research Laboratory (AADRL). Here he argues that Parametricism 2.0 has a vital role to play in the progressing of computational design. Assimilating the exploratory developments of the last 15 years, he asserts how the next phase of Parametricism will enable a further consolidation and evolution of digital practices. 相似文献

Penelope Dean 《Architectural Design》2009,79(3):24-29
Could the primacy of green architecture in recent years be eroding the discipline? Is it reducing architecture to a mere ‘environmental techno-science’? Penelope Dean argues for a revised environmental agenda that is driven by ideas and concepts rather than subservient technologies. Copyright © 2009 John Wiley & Sons, Ltd. 相似文献
