Research and Development to Support an Ultra-Energy-Efficient Residential Building Stock in Ontario

加拿大存在利用超绝缘建筑围护结构(SIBE)技术(即墙、屋顶、板、窗和门)来设计和建造可显著降低运行能源的超节能(UEE)房屋的需求。提出的研究问题是，目前的围护结构设计没有直接过渡到超绝缘建筑围护结构设计。许多案例突出了当前设计被用作SIBE设计框架时的有害影响(例如，霉菌变质)。拟议的项目将进行分析性研究，以量化成功标准，利用实验室和实地实验来填补传统建筑围护结构设计理念与SIBES理念之间的知识空白，以支持发展一个标准的UEE住宅市场。 *工作性质* 拟议的研究将利用定量研究支持的性能标准，为加拿大气候特定的SIBE技术制定建议。将制定与SIBES业绩直接相关的成功标准，作为支持成果分析的分析支柱。研究将通过实验室和现场足尺实验进行测试和分析。将使用经过实验验证的模拟模型生成额外的性能数据。这项工作的成果支持开发、改造和建设SIBES，以支持和改善加拿大各地的住房存量。 *为什么研究很重要* 住宅能源使用量占加拿大能源使用量的很大一部分(约15%)。为了减少加拿大的能源消耗，加拿大人需要通过利用SIBES来设计和建造UEE建筑，这些建筑是健康、耐用、节能和成熟的。这项拟议的研究很重要，因为它直接支持在建筑和社区规模上大幅提高能效。为了减少高水平的能源消耗，需要耐用和可建造的SIBE。 *研究对谁重要* 这项研究对普通民众、工业界和学术界都具有重要意义。公众将受益于可使用的锡贝组件的开发。工业将受益于绿色经济部门的直接市场增长，如可持续材料、建筑和可再生能源。学术界将受益于提供与SIBES相关的具体结果的前沿研究，以及未来的研究，以扩大研究领域。 *预期结果* -将公布测量数据，以支持对超节能房屋日益增长的需求，同时使用确保耐用、可持续建筑库存的战略。 -将公布制定分级目标系统的结果，并公布加拿大SIBE组件的设计和建造指南。 -将向管理守则和标准提出具体建议，使各节侧重于SIBE系统。这些数据将与数据结合起来，以支持高效的能源输送系统以及可再生能源和生物能源系统。 -该项目的建筑围护结构和系统研究成果将得到建筑和制造业能力的批判性分析，以采用拟议的超节能战略。 *研究领域和加拿大将如何受益* 拟议的项目将通过量化SIBES的绩效来减少加拿大能源生产和使用对环境的影响，以支持全国各地UEE住房的设计和建设。由此产生的能源削减目标将直接使加拿大能够在2020年前实现温室气体减排，仅在短期内就可能产生超过15亿美元的收入。

The demand exists in Canada to utilize super-insulated building envelope (SIBE) technology (i.e. walls, roofs, slabs, windows and doors) to design and construct ultra-energy-efficient (UEE) houses that significantly reduce operational energy. The proposed research problem is that current designs of building envelope assemblies do not directly transfer to super-insulated building envelope designs. Numerous cases highlight deleterious effects (e.g. mould deterioration) when current design has been used as a framework for SIBE design. The proposed project will conduct analytical research to quantify success criteria utilizing laboratory and field experiments to fill the knowledge gap between traditional building envelope design philosophy and that of SIBEs to support the development of a standard market of UEE residential dwellings. ***Nature of the Work*** The proposed research will develop recommendations for Canadian climate specific SIBE technologies using performance criteria backed by quantitative research. Success criteria directly related to the performance of SIBEs will be developed as the analytical back-bone to support results analysis. The research will be tested and analyzed through laboratory and in-situ full-scale experimentation. Additional performance data will be generated using experimentally validated simulation models. Results from this work support the development, adaptation and construction of SIBEs to support and UEE housing stock across Canada. ***Why is the Research Important*** Residential dwelling energy use accounts for a significant amount of Canada’s energy use (approximately 15%). In an effort to reduce Canada’s energy consumption, Canadians require the means to design and construct UEE buildings through utilizing SIBEs that are healthy, durable, energy efficient and proven. The proposed research is important because it directly supports significant energy efficiency increases at both the building and community scale. In order to reduce the high level energy use, durable and constructible SIBEs are required. ***To Whom is the Research Important*** The research is important to the general public, industry and academia. The general public will benefit from development of useable SIBE assemblies. Industry will benefit from direct market growth in green economy sectors such as sustainable materials, construction and renewables. Academia will benefit from leading edge research providing concrete results related to SIBEs and future research to grow the field of study. ***Anticipated Outcomes*** -Measured data will be published to support the increasing demand of ultra-energy-efficient houses while using strategies that ensure a durable, sustainable building stock. -Results to develop a tiered target system and publish guidelines for design and construction of SIBE assemblies in Canada will be published. -Specific recommendations will be made to governing codes and standards to focus sections on SIBE systems. This data will be coupled with data to support highly efficient energy delivery systems and renewable and bio-energy systems. -The building envelope and systems research output from this project will be complimented by critical analysis of the construction and manufacturing sectors capacity to adopt the proposed ultra-energy-efficient strategies. ***How the Research Field and Canada Will Benefit*** The proposed project will reduce Canada’s environmental impacts of energy production and use through quantifying performance of SIBEs to support the design and construction of UEE homes throughout the nation. The resulting target energy reductions will directly enable Canada to achieve their GHG emission reductions by 2020 and could result in over $1.5 billion in the near term alone.
