The proposed research program aims to advance integration of low carbon, intensive, bio-based building materials in sustainable building design through research and development. Investigation of the energy and hygrothermal performance as well as the potential impact of the bio-based materials on the indoor environment are the foci of the program. The research activities in the program span from materials to bio-based building envelope assemblies and to whole-building performance analysis, where the dynamic heat, air and moisture (HAM) interactions between building envelope components, indoor environments and mechanical systems will be studied. The program seeks to optimize such buildings’ performance, cost and environmental benefits while minimizing the durability risk. The long-term goals of the proposed research program are to develop high performance bio-based materials that are environmentally friendly, energy efficient, durable and cost effective, and to develop design guidelines and standards for the use of bio-based materials in sustainable building design. In the short-term, the research program focuses on understanding and characterizing the thermal and moisture performance of bio-based materials with hemp fiber, flex fiber and wheat straw to lay the foundation of knowledge for the stated long-term goals. The research program applies both experimental and numerical research methods, and is supported by three existing research infrastructures — the Hygrothermal Property Measurement Laboratory (HPML), the Building Envelope Test Facility (BETF), and the Whole-Building Performance Research Laboratory (WBPRL) — and numerical tools such as building envelope hygrothermal models (HAMFit1D, HAMFit2D), a whole-building model (HAMFitPlus), a probabilistic HAM model, and a multi-objective optimization model. It is envisioned that this research program will significantly contribute to the training of graduate students, and thereby increase the limited number of highly qualified-personnel (HQP) in the building science field to tackle the challenges that the construction industry is currently facing. The research program’s aim is to reduce the environmental impact of buildings, to increase economic opportunities, and to provide social and health benefits for Canadians.

拟议的研究项目旨在通过研究和开发，推动低碳、集约化、生物基建筑材料在可持续建筑设计中的整合。研究能源和湿热性能以及生物基材料对室内环境的潜在影响是该项目的重点。该计划的研究活动涵盖从材料到生物基建筑围护结构组件以及整个建筑性能分析，其中将研究建筑围护结构组件，室内环境和机械系统之间的动态热，空气和水分（HAM）相互作用。该项目旨在优化此类建筑的性能、成本和环境效益，同时将耐久性风险降至最低。该研究计划的长期目标是开发环保、节能、耐用和成本效益高的高性能生物基材料，并为可持续建筑设计中使用生物基材料制定设计指南和标准。在短期内，研究计划侧重于了解和表征大麻纤维、柔韧纤维和麦秆生物基材料的热湿性能，为既定的长期目标奠定知识基础。该研究计划应用实验和数值研究方法，并由三个现有的研究基础设施-湿热特性测量实验室（HPML），建筑围护结构测试设施（BETF）和整体建筑性能研究实验室(WBPRL) -提供支持和数值工具，如建筑围护结构湿热模型（HAMFit1D, HAMFit2D），整个建筑模型（HAMFitPlus），概率HAM模型和多目标优化模型。预计该研究项目将对研究生的培养做出重大贡献，从而增加建筑科学领域有限的高素质人才（HQP）数量，以应对建筑行业目前面临的挑战。该研究项目的目的是减少建筑对环境的影响，增加经济机会，并为加拿大人提供社会和健康效益。
