Solid cork building envelope

研究小组将参与每个工作包，与项目负责人和其他人密切合作，重点是环境设计和性能测试。核心研究的目的是调查、开发和测试一种几乎完全由固体、承重膨胀软木制成的极其简单的建筑围护系统的可行性和实际性能。该系统将包括墙壁和屋顶元件，并将被设计为预制建筑套件，以便于通过干接缝进行简单的现场组装，以及在建筑寿命结束时进行简单的改造和拆卸以重新使用或回收。支持性研究将评估整个生命周期的性能，利用生命周期评估（LCA）建模-从生物多样性森林中软木的起源，到体现碳负产品，再到有助于提供良好隔热，低能耗和健康室内环境的坚固建筑外壳，并最终进行拆卸和再利用。将对有人居住的Cork House进行监测，并收集能源使用等数据，作为使用后评估的一部分。这将提供实际环境和能源性能的证据，这些数据也将用于LCA建模。拟议系统的基本简单性旨在消除典型多层建筑围护结构的复杂性以及通常与此相关的建筑全寿命性能问题：-由于设计不同组件和系统之间的众多复杂定制接口所需的时间，导致建筑设计成本过高。由于需要许多行业按照规定的顺序参与围护结构施工，因此费用和施工周期过多，延迟和不可预见成本的风险增加。由于许多层和组件的综合性能不符合预期，建筑围护结构的性能较差。例如，由于组件之间的公差和界面不同而导致的气密性差，或者由于组件的热膨胀或蒸汽渗透性不同而导致的外壳随时间的退化。由于修改和连接复杂信封组件的成本和挑战，适应性有限。在建筑物使用寿命结束时进行破坏性拆除，由于为重新使用而进行拆除，造成资源退化，而且由于采用原来的组装方法，许多部件无法回收，项目最后将研究建筑物系统的商业可行性，包括根据市场机会进行调整的可能性。预计拟议制度将适用于房屋、自建、天台发展和各类附属住房。

The research team will be involved in each work package, working in close collaboration with the project lead and others, with a focus on environmental design and performance testing. The core research aims to investigate, develop and test theviability and actual performance of a radically simple building envelope system made almost entirely from solid, loadbearing expanded cork.The system will include wall and roof elements and will be designed as a prefabricated construction kit to facilitate simple on-site assembly with dry-joints, as well as simple adaptation and disassembly for re-use or recycling at the end of the building life.Supporting research will evaluate whole-life performance, utilizing Life Cycle Assessment (LCA) modelling - from the origins of the cork in biodiverse forests, to an embodied carbon-negative product, to solid building envelope helping to deliver a well-insulated, low-energy and healthy indoor environment, and on to eventual disassembly and reuse. The inhabited Cork House will be monitored and energy use, etc. data collected as part of a Post-Occupancy Evaluation. This will provide evidence of actual environmental and energy performance, and this data will also be used in the LCAmodelling.The essential simplicity of the proposed system aims to eliminate the complexity of the typical multi-layered building envelope and the building whole-life performance problems often associated with this:- Excessive building design costs due to the time needed to design numerous complex, bespoke interfaces between dissimilar components and systems.- Excessive expense and construction period and increased risk of delay and unforeseen cost due to the need for many trades to contribute to envelope construction in prescribed sequences.- The poor performance of the building envelope due to aggregate performance of the many layers and components not being as predicted. For example, poor airtightness due to differing tolerances and interfaces between components or the degradation of the envelope over time due to the dissimilar thermal expansion or vapour permeability of components.- Limited adaptability due to the cost and challenge of modifying and interfacing with complex envelope assemblies.- Destructive demolition at the end of the building life degrading resources due to deconstruction for re-use being unaffordably time-consuming and many components being unrecoverable due to the original method of assembly.The project would conclude with research on the commercial viability of the building system, including its potential adaptation in response to market opportunities. It is anticipated that the proposed system would be applicable to housing, self-build, rooftop development, and types of ancillary accommodation.
