The proposed research is aimed to investigate the use of Expanded Polypropylene (EPP) in a prefabricated wall system. EPP has superior thermal and physical properties allowing it to be suitable as a thermal insulation and structural material in the building envelope. The manufacturing and moulding process of EPP has been matured in a streamlined and cost-effective manner in the automobile industry. The proposed research will investigate how the manufacturing process of EPP parts from the automobile industry can be transferred to manufacturing prefabricated wall panels for use in constructing sustainable and affordable housing. Blue Valley Building (BVB) Corporation is a vertically integrated company based in Guelph with extensive knowledge from the automobile and construction industries. Their research and development activities focus on innovating the manufacturing process aligned with lean construction principles to develop prefabricated wall and floor systems that will significantly reduce waste, improve the quality of the building envelope, minimize costs, and increase productivity in the Canadian affordable housing industry. The academic team seeks to quantify the performance of the proposed EPP-based wall panels through simulation and laboratory testing with a specific focus on the panel's thermal, structural, and fire safety performance. The performance of the proposed design will be assessed in terms of structural stability, airtightness, and thermal bridge-free detailing. In addition, the impact of the proposed EPP-based wall panel on building energy efficiency and compliance with the Building Codes will be assessed through building energy simulation. The objective is to guide the appropriate design decisions needed towards ensuring high-performance for the wall system whilst minimizing construction cost and the generation of waste through adopting a lean manufacturing process. The outcomes will be commercialized by BVB through implementing the EPP-based wall panel system on approximately 21 of their mid-rise residential projects across Ontario and supplying the wall panels to other builders.

拟议的研究旨在研究在预制壁系统中使用扩展的聚丙烯（EPP）的使用。 EPP具有优异的热和物理特性，使其适合建筑物包膜中的热绝缘和结构材料。 EPP的制造和成型过程已在汽车行业以简化且具有成本效益的方式成熟。拟议的研究将调查如何将汽车行业的EPP零件制造过程转移到制造预制的墙板上，以用于构建可持续和负担得起的住房。 Blue Valley Building（BVB）Corporation是一家垂直整合的公司，总部位于Guelph，拥有来自汽车和建筑行业的广泛知识。他们的研发活动着重于创新与精益建筑原则相一致的制造过程，以开发预制的墙壁和地板系统，这些墙壁和地板系统将大大减少浪费，改善建筑物包封的质量，最小化成本并提高加拿大负担得起的住房行业的生产率。学术团队旨在通过模拟和实验室测试来量化拟议的基于EPP的墙板的性能，并特别关注该面板的热，结构和消防安全性能。建议的设计的性能将根据结构稳定性，气密性和无热桥细节进行评估。此外，将通过建筑能源模拟评估拟议的基于EPP的墙板对建筑能源效率和遵守建筑法规的影响。目的是指导确保墙壁系统高性能所需的适当设计决策，同时通过采用精益制造工艺来最大程度地减少建筑成本和产生废物的产生。 BVB将通过在安大略省的大约21个中期住宅项目上实施基于EPP的墙板系统并将墙板提供给其他建筑商，从而通过BVB进行商业化。
