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、城市中心发展压力日益增大、气候变化以及自然和人为灾害，都促使对可持续和低成本建筑的需求大增。在加拿大，住房和社区发展的需求已变得更加复杂，住房成本上升，无家可归，新移民的到来，以及减少环境影响的政治动力。加拿大政府已签署了一项雄心勃勃的减排目标，以应对气候变化，旨在到2050年将温室气体（GHG）排放量与2005年相比减少80%。据国际能源署统计，建筑物消耗了全球36%的能源，排放了近40%的温室气体。低影响微型社区发展已成为最大限度地减少温室气体排放和改善社会经济福祉的潜在解决方案。微型社区是指人口少于30，000人的同质化小规模社区，具有共同的治理结构和特征。我的研究项目旨在调查和提出发展经济上可行的微型社区的战略，以最小的环境影响，同时也服务于居住者的需求。主要目标是发展基于生命周期思维的建设、运营和管理战略以及技术集成，以提高加拿大微型社区的可持续性。生命周期思维原则将被应用于确保所提出的解决方案是真正可持续的，而不仅仅是将影响从一个生命周期阶段转移到另一个阶段。这是我的研究计划与过去十年中产生的知识的自然演变。以下是次级目标。1.识别和评估低影响的技术和战略的建设，运营和管理的小型和微型社区2。开发和分析基于被动和模块化结构的建筑解决方案，以实现资源高效的微型社区3.为微型社区的低影响基础设施发展制定建设标准、基准和基于生命周期思维的规划和运营框架4.为加拿大不同气候区域的低影响微型社区基础设施发展制定项目交付方法和合同战略提出政府政策和最佳管理实践，以促进加拿大可持续微型社区发展，特别是在北方气候地区我的研究计划的成果，包括决策支持工具和最佳实践将有利于社区开发商，建筑业和政策制定者，在解决住房负担能力，无家可归，气候变化和可持续资源利用的挑战。关于微型社区发展的拟议政策将协助地方、省和联邦各级政府促进低影响建筑。
