Rapid population growth, increasing pressures of development at urban centres, climate change, and natural and human-made disasters have all contributed to a significant demand for sustainable and low-cost construction. In Canada, housing and community development needs have become further complex with the rising housing costs, homelessness, incoming new immigrants, and the political drive to reduce environmental impacts. The Government of Canada has subscribed to an ambitious emissions reduction target to battle the climate change, which aims to cut-down the greenhouse gas (GHG) emissions by 80% compared to 2005 levels by 2050. According to International Energy Agency statistics, buildings consume 36% of the global energy and emit nearly 40% of the GHG emissions. Low-impact micro-community development has emerged as a potential solution to minimize GHG emissions and improve socio-economic wellbeing. Micro communities are defined as homogenised small-scale communities with a population less than 30,000 that share a common governance structure and characteristics. My research program aims to investigate and propose strategies for developing economically viable micro-communities with minimal environmental impacts, while also serving the occupants' needs. The main objective is to develop life cycle thinking based construction, operation, and management strategies and technology integrations, to enhance the sustainability of the Canadian micro-communities. Life cycle thinking principles will be applied to ensure the proposed solutions are truly sustainable, instead of merely moving impacts from one life cycle phase to another. This is a natural evolution of my research program with the knowledge generated in the past decade. Following are the sub-objectives. 1. Identify and evaluate low-impact technologies and strategies for construction, operation, and management of small and micro-communities 2. Develop and analyze passive and modular construction-based building solutions for resource efficient micro-communities 3. Develop construction standards, benchmarks, and a life cycle thinking based planning and operation framework for low-impact infrastructure development in micro-communities 4. Develop project delivery methods and contract strategies for low-impact micro-community infrastructure development in different climatic regions of Canada 5. Propose governmental policies and best management practices for advancing sustainable micro-community development in Canada, especially in the Northern climatic regions The outcomes of my research program including decision support tools and best practices will be beneficial to community developers, construction industry, and policymakers, in resolving challenges related to housing affordability, homelessness, climate change, and sustainable resource use. The policies proposed on micro-community development will assist local, provincial, and federal level governments in promoting low-impact construction.

人口迅速增长，城市中心的发展压力增加，气候变化以及自然和人为的灾难都促成了对可持续和低成本建设的重大需求。在加拿大，住房和社区发展需求随着住房成本的上升，无家可归，新移民以及减少环境影响的政治动力而变得更加复杂。加拿大政府已订阅雄心勃勃的减少排放量来抗击气候变化，该目标旨在将温室气体（GHG）排放量减少80％，而到2050年的2005年水平，根据国际能源机构的统计数据，建筑物消耗了36％的全球能源，并占据了几乎40％的GHG散热。低影响的微共享发展已成为最大程度地减少温室气体排放并改善社会经济福祉的潜在解决方案。它们被定义为同质的小型社区，人口少于30,000，具有共同的治理结构和特征。我的研究计划旨在调查和提出提出策略，以发展经济上可行的微观共同社区，同时还可以满足职业的需求。主要目的是开发基于生命周期的建筑，运营和管理策略和技术整合，以增强加拿大微共享的可持续性。生命周期思维原则将被应用以确保所提出的解决方案是真正可持续的，而不仅仅是从一个生命周期阶段转变为另一个生命周期的影响。这是我的研究计划的自然演变，其知识在过去十年中产生的知识。以下是子目标。 1。识别和评估小型和微型社区的构建，操作和管理的低冲击技术和策略2。开发和分析用于资源有效的微型社区的被动和基于模块化的基于施工的建筑解决方案3. 33。制定基于生命周期的基于生命周期的计划和基于生命周期的计划框架的基于生命周期的计划和低水平构造方面的构建标准，基于生命周期思维的计划，以进行计算策略，以开发对Micro-Imppration Impport in Micro-Impport in Imppor Impport in Imppt Impport in Imppt Impport 4。加拿大不同气候地区的微型社区基础设施发展5。提出政府政​​策和最佳管理实践，以推进加拿大可持续的微型社区发展，尤其是在北部气候区域，我的研究计划的成果（包括决策工具和最佳实践）将对社区开发商，建筑行业，建筑业和政策范围内的范围有利于综合能力，是有益 使用。关于微社区发展的政策将有助于地方，省和联邦一级政府促进低影响力的建设。
