Development of Advanced Building Systems with PCM, VIP, and AEROGEL

该项目旨在推进知识和促进与开发先进和响应式建筑系统相关的研究，这些系统集成了一些纳米技术和新的建筑材料，如相变材料（PCM），真空隔热板（VIP）和气凝胶，相变材料在相变过程中具有很高的潜热，可用于减少建筑物的温度波动，通过增加建筑物的热容量来实现（轻质）建筑。最近大规模生产的新的微胶囊PCMs承诺更广泛的传播建筑系统纳入PCMs，但其潜力为加拿大建筑部门仍然是未开发的。同样，虽然VIP和气凝胶的导热系数非常低，但它们是最有前途的超级隔热材料之一，将其纳入先进的预制建筑系统仍然可以忽略不计。该项目将主要采用实验方法，同时结合理论研究，软件模拟，该项目将首先在PI的建筑科学实验室对一些PCM、VIP和气凝胶产品进行热物理表征。然后，研究将集中在透明和不透明的纳米技术增强建筑系统的设计和开发上。在透明系统中，将测试具有半透明PCM的双层玻璃和在不同腔中具有PCM和气凝胶的三层玻璃。在不透明系统中，将测试多层面板，核心是VIP或气凝胶面板，以及室内侧的不同PCM增强轻质板。还将研究在其空腔中具有气凝胶或作为隔热层的窗框。在该项目的第二阶段，将在多伦多使用配备有原型创新系统的仪器化测试单元进行实地实验。最后，该项目将涉及在真实的建筑中安装一些系统，该项目的主要目标是：-在加拿大气候条件下开发和测试先进的建筑系统，并评估不同建筑类型的节能潜力，包括建筑改造，同时考虑老化性能;-培训HQP开发新的先进建筑系统，并帮助将最新的材料科学发现技术转移到国家建筑部门。

This project aims to advance knowledge and promote research related to the development of advanced and responsive building systems that integrate some nanotechnologies and new building materials, such as Phase Change Materials (PCMs), vacuum insulating panels (VIPs), and aerogel, to drastically reduce a building's energy demand.PCMs have a high latent heat during phase change and may be used for reducing the temperature swings of (lightweight) buildings by increasing the building thermal capacity. The recent mass production of new microencapsulated PCMs promises a wider dissemination of building systems incorporating PCMs, but their potential for the Canadian building sector is still unexplored. Similarly, although the remarkably low thermal conductivity of both VIPs and aerogels, which are among the most promising super-insulating materials, their inclusion in advanced prefabricated building systems is still negligible.The project will mainly adopt an experimental approach, while also incorporating theoretical studies, software simulations, and technology transfer and dissemination activities.The project will start with the thermo-physical characterization at the PI's Building Science Lab of some PCMs, VIPs, and aerogel products. The research will then focus on the design and development of transparent and opaque nanotech-enhanced building systems. Among the transparent systems, double glazing with translucent PCMs and triple glazing with PCMs and aerogel in different cavities will be tested. Among the opaque systems, multi-layer panels, with VIPs or aerogel panels in the core, and different PCM-enhanced lightweight boards on the indoor side will be tested. Window frames with aerogel in their cavity or as thermal breakers will also be investigated. In the second phase of this project, field experiments will be carried out in Toronto using instrumented test cells equipped with the prototyped innovative systems. Lastly, the project will involve the installation of some systems in real buildings.The main goals of this project are:- to develop and test advanced building systems in the Canadian climatic conditions and to assess the energy saving potential for different building typologies, including for building retrofitting, while considering the aging performance;- to train HQP on the development of new advanced building systems and to help the technological transfer of the latest material science discoveries into the national construction sector.
