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.

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。核心研究旨在调查、开发和测试一种几乎完全由固体、承重膨胀软木制成的简单建筑围护结构系统的可行性和实际性能。该系统将包括墙壁和屋顶元素，并将被设计为预制的建筑套件，以方便简单的现场装配和干接头，以及简单的改装和拆卸，以便在建筑寿命结束时重新使用或回收。支持性研究将利用生命周期评估（LCA）模型来评估整个生命周期的性能——从生物多样性森林中的软木的起源，到具体的负碳产品，再到有助于提供良好绝缘、低能耗和健康室内环境的固体建筑围护结构，再到最终的拆卸和再利用。作为入住后评估的一部分，将对居住的软木房屋进行监测，并收集能源使用等数据。这将提供实际环境和能源表现的证据，这些数据也将用于lcammodeling。所提议的系统的本质简单性旨在消除典型多层建筑围护结构的复杂性，以及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众多复杂的定制接口所需的时间而导致的过高的建筑设计成本。-由于需要许多行业按照规定的顺序进行围护结构施工，费用和工期过高，延误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透气性不同而导致的外壳随着时间的推移而退化。-由于成本和修改和连接复杂外壳组件的挑战，适应性有限。-在建筑寿命结束时进行破坏性拆除，由于重新使用而进行的解构导致资源退化，这是无法承受的，耗时且许多组件由于原始组装方法而无法恢复。该项目最后将研究建筑系统的商业可行性，包括对市场机会的潜在适应。预计拟议的制度将适用于房屋、自建、屋顶发展和各种附属住房。
