The long-term goal of my research program is to develop models, decision support tools, construction techniques, and guidelines to improve the sustainability of construction projects. The overarching objective for the next 5 years is to develop scientifically proven practical solutions, best management practices, and construction techniques to optimize the water-energy-carbon nexus in new urban neighbourhood development (UND). The proposed research in the next 5 years is a natural evolution of my research program. *** Many recent research studies have emphasized Canada's relatively poor overall sustainability performance compared to other developed countries. Since our world is a giant network of interconnected neighbourhoods, a neighbourhood can be used to initiate an unique movement towards global sustainability. Urban neighbourhoods can be observed as organisms, with inputs of water, energy, and materials and outputs of emissions and wastes hypothesized as similar to the human metabolic processes. The life cycle phases of a construction project consist of material extraction, delivery, project design, construction, occupancy or use, maintenance, and decommissioning. This process can be viewed by considering the resource uses and waste/emission releases in an urban neighbourhood's metabolic system. Water and energy, which can be recognized as the most critical streams of an urban neighbourhood's metabolic processes, have substantial life cycle impacts on Green House Gas (GHG) emissions. On a global scale, greenhouse gas reduction is becoming a measure of sustainable performance. Therefore, analyzing water and energy performance, and their life cycle impacts, in terms of greenhouse gas emissions, is a timely and scientific approach for assessing the life cycle sustainability of UNDs.*** The primary objective of my research program in the next 5 years is to develop innovative and practical technological solutions, best management practices, and construction methods for optimizing water and energy use, while minimizing the GHG emissions, in UNDs. The sub-objectives in the next 5 years include 1) a life cycle based environmental and economic assessment of state-of-the-art water and energy systems for UNDs; 2) development of construction and asset management practices for UNDs; 3) development of a Building Information Modelling (BIM) and System Dynamic Modelling (SDM) based decision support tool to optimize the water-energy-carbon (GHG) nexus during the life cycle of UNDs; and 4) development of a Geographic Information System (GIS) based sustainability assessment tool for location specific sustainability assessments in UNDs. In addition, the above sub-objectives will lead to the development of life cycle based best management practices and guidelines to achieve an optimal water-energy-carbon nexus in future UNDs in Canada and globally. **

我的研究计划的长期目标是开发模型，决策支持工具，建筑技术和指南，以提高建筑项目的可持续性。未来5年的总体目标是开发科学证明的实用解决方案，最佳管理实践和建筑技术，以优化新城市邻里开发（UND）中的水能碳Nextus。未来5年的拟议研究是我的研究计划的自然发展。 ***许多最近的研究强调，与其他发达国家相比，加拿大相对较差的总体可持续性绩效。由于我们的世界是一个相互联系的巨大网络，因此可以使用一个社区来启动朝着全球可持续发展的独特运动。可以将城市社区视为有机体，其中有水，能量，材料以及排放和废物的输出，假设与人类代谢过程相似。建筑项目的生命周期阶段包括材料提取，交付，项目设计，建筑，占用或使用，维护和退役。可以通过考虑城市代谢系统中的资源用途和废物/排放释放来查看此过程。水和能源可以被认为是城市邻里代谢过程中最关键的流，对温室气体（GHG）排放产生了重大的生命周期影响。在全球范围内，减少温室气体正在成为衡量可持续性能的衡量标准。因此，在温室气体排放方面，分析的水和能源性能以及它们的生命周期的影响是评估UNDS生命周期可持续性的及时，科学方法。接下来的5年中的亚物品包括1）基于生命周期的环境和经济评估，对UND的最先进的水和能源系统； 2）开发UNDS的建设和资产管理实践； 3）基于建筑信息建模（BIM）和系统动态建模（SDM）的决策支持工具的开发，以优化UNDS生命周期中的水能碳（GHG）Nexus； 4）开发基于地理信息系统（GIS）的可持续性评估工具，用于UNDS中的特定可持续性评估。此外，上述亚物品将导致基于生命周期的最佳管理实践和准则的发展，以实现加拿大和全球未来UNDS的最佳水能碳核关系。 **
