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

该项目旨在促进与先进和响应性建筑系统的开发相关的知识和研究，这些系统集成了一些纳米技术和新型建筑材料，如相变材料(PCMs)、真空绝缘板(VIPS)和气凝胶，以大幅降低建筑物的能源需求。相变材料在相变期间具有很高的潜热，可用于通过增加建筑热容量来减少(轻型)建筑的温度波动。最近大规模生产的新型微胶囊相变材料有望更广泛地推广含有相变材料的建筑系统，但其在加拿大建筑业的潜力仍未开发。同样，尽管VIP和气凝胶这两种最有前途的超级绝缘材料的导热系数非常低，但它们在先进的装配式建筑系统中的应用仍然可以忽略不计。该项目将主要采用实验方法，同时也包括理论研究、软件模拟以及技术转移和推广活动。该项目将从PI的建筑科学实验室对一些相变材料、VIP和气凝胶产品的热物理表征开始。然后，研究将集中在透明和不透明纳米技术增强建筑系统的设计和开发上。在透明系统中，将测试半透明相变材料的双层玻璃和不同腔体中的相变材料和气凝胶的三层玻璃。在不透明系统中，将测试以VIP或气凝胶面板为核心的多层面板，以及室内一侧不同的PCM增强轻质板。还将调查空腔中有气凝胶或用作热断路器的窗框。在该项目的第二阶段，将在多伦多使用配备原型创新系统的仪表化测试单元进行现场实验。最后，该项目将涉及在实际建筑中安装一些系统。该项目的主要目标是：-在加拿大的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，并帮助将最新材料科学发现的技术转移到国家建筑业。

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.
