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，施工技术和指导方针，以提高建筑项目的可持续性。未来5年的总体目标是开发经过科学验证的实用解决方案，最佳管理实践和施工技术，以优化新城市社区开发（UND）中的水-能源-碳关系。未来5年的研究计划是我研究计划的自然演变。* 最近的许多研究强调，与其他发达国家相比，加拿大的总体可持续性表现相对较差。由于我们的世界是一个由相互联系的社区组成的巨大网络，因此可以利用社区来发起一场实现全球可持续性的独特运动。城市街区可以被视为有机体，水、能源和材料的输入以及排放和废物的输出被假设为类似于人类的代谢过程。建筑项目的生命周期阶段包括材料提取、交付、项目设计、施工、占用或使用、维护和退役。这一过程可以通过考虑城市居民区代谢系统中的资源使用和废物/排放来看待。 水和能源被认为是城市居民区代谢过程中最关键的两股流，对绿色家用气体（GHG）排放具有重大的生命周期影响。在全球范围内，温室气体减排正在成为衡量可持续绩效的一个指标。 因此，从温室气体排放的角度分析水和能源绩效及其生命周期影响，是评估联合国发展系统生命周期可持续性的一种及时和科学的方法。我的研究计划在未来5年的主要目标是开发创新和实用的技术解决方案，最佳管理实践和施工方法，以优化水和能源的使用，同时最大限度地减少温室气体排放，在UND。今后5年的次级目标包括：1）对联合国发展系统最先进的水和能源系统进行基于生命周期的环境和经济评估; 2）制定联合国发展系统的建设和资产管理做法; 3）开发基于建筑信息模型（BIM）和系统动态模型（SDM）的决策支持工具，以优化水-能源-碳（GHG）（c）在联合国发展系统的生命周期中，建立一个可持续性评估工具，以地理信息系统为基础，对联合国发展系统中具体地点的可持续性进行评估。此外，上述次级目标将导致制定基于生命周期的最佳管理做法和准则，以便在加拿大和全球未来的联合国发展战略中实现水-能源-碳的最佳关系。
