商业建筑绿色节能改造协同设计过程及智能化网络工程平台的研究

Recent research shows that green retrofitting of existing buildings is vital for the achievement of low carbon target. Green Retrofitting Design (GRD) however faces many unique challenges such as the dynamic and iterative processes where stakeholders interact to collect, communicate, analyse and integrate the complex and scattered design information. Additionally, design decision-making and solutions are affected by multiple needs (energy efficiency, carbon emissions, indoor environment), internal and external constraints (physical and budgetary limitations, available technologies, regulations) and different analysis methods and criteria, where novel design solutions are necessary. Owners, even designers, often lack knowledge and experience in managing the processes and developing solutions that satisfy the complex objectives and constraints. ..This research targets a thorough and systematic study on GRD for commercial buildings in China in terms of the processes, key issues, performance and challenges; and the conceptual development and implementation of an Integrated, Intelligent and Innovative e-Engineering Environment for stakeholders in managing the GRD processes and supporting design solution development (I3E-GRD). The specific research objectives are: (1) to identify and analyse the key stages, issues, roles, collaboration, information flow, and approaches to developing GRD solutions, from a design process perspective; (2) to develop a workflow-based GRD process model which will address the key collaboration and design issues during the GRD processes (e.g. who should be involved at which stage, collaborate with whom, with what issues to address, and in making what decisions); and (3) to develop the I3E-GRD which offers integrated services to facilitate the GRD processes, in particular the support of design option and technology selection, by incorporating the GRD process model supported with intelligent agents. ..These objectives will be achieved by adopting a group of rigorous research methods including: case study, interview, focus group meetings, modelling and expert evaluation. ..The research outcomes will be extremely valuable and timely for the local construction industry in particular and the international community at large. It will lead to new knowledge and improved understandings of the processes, issues, and decisions in the GRD processes. The GRD process model and the I3E-GRD built upon it will make the GRD processes transparent and manageable with more innovative and feasible solutions developed. This proposed investigation will play a significant role in reducing energy intensity and bringing economical and health benefits to stakeholders, and eventually helping China to achieve its low carbon target. The study will also further develop and enrich workflow theory. The integration of process model and content template offers a new systematic approach to solving multi-disciplinary, multi-objective, multi-constraint problems.

与设计新建筑物或普通翻修改造的不同，对既有建筑，特别是商业建筑的绿色节能改造设计（Green Retrofit Design - GRD）面临着许多独特的挑战，如动态和反复的过程，以及受社会、经济、环境、技术等多专业、多目标、多变量、多约束影响的复杂决策问题。各方对GRD也缺乏必要的知识和经验。本项目以工作流理论为基础,将1）系统地研究GRD的特点、过程及各设计阶段的参与方、影响因素、信息流、设计内容和决策等；2）构建基于工作流的GRD过程模型以掌握其核心问题（如谁在什么阶段参与、与谁协作、设计内容、及设计信息的收集、交流、分析和综合），从而提高复杂动态的GRD过程的透明度和可控性；3）在此基础上，建立由智能代理支持的协作、智能、创新的GRD网络工程服务系统（I3E-GRD），以解决复杂动态的GRD问题。本研究将对我国节能减碳有着重大现实意义，并对于工作流理论的进一步发展有着极大学术价值。

近期研究显示既有建筑改造是达到节能减排目标至关重要的方式。尽管如此，既有建筑改造依旧面临着巨大的挑战，比如利益相关者之间信息的采集，利益相关者的合作策略以及激励政策的优化。本项目主要研究工作包括：1）系统地研究既有建筑绿色翻新改造的特点、过程、利益相关者、影响因素和决策策略等；2）构建基于博弈论的绿色翻新改造决策模型以掌握不同情况下利益相关者的策略以及最优政策和决策，以提高复杂动态的绿色翻新改造决策过程的透明度和可控性；3）在此基础上，建立基于智能代理的协作、智能、创新的绿色翻新改造决策支持系统，以解决动态过程中多利益相关者参与的决策问题。本研究工作将对推进我国节能减排工作产生重大现实意义，并且智能多代理系统在绿色建筑改造决策支持领域的应用产生理论创新，蕴含着极大的学术价值。
