CPS: Medium: Collaborative Research: Building Information, Inhabitant, Interaction and Intelligent Integrated Modeling (BI5M)

美国每年花费超过4000亿美元用于为建筑物供电、供暖和制冷。此外，建筑物是环境排放的主要来源。因此，即使国家建筑存量的能效略有提高，也会带来可观的经济和环境效益。在这个项目中，重点是提高商业建筑的能效，因为这一部门占整个建筑部门能源使用和成本的很大一部分。提高商业建筑的能效是一个具有挑战性的问题，因为集中式建筑系统--如供暖、通风和空调(HVAC)或照明--必须与个人居民行为和能源消耗模式综合和集成。该项目旨在设计、分析和测试一种能够推动商业建筑持续节能的数字物理和人在环启用的控制系统。它汇集了计算建筑科学、生态反馈、网络理论、数据科学和控制系统方面的专业知识，将物理建筑信息和居民与网络(建筑-人)交互模型集成在一起，实现了对商业建筑系统的智能控制。具体地说，该项目将：1)设计一个集成的网络物理系统(CPS)，称为建筑信息、居民、交互、智能集成建模(BI5M)，旨在减少建筑中的能源消耗；2)评估与节能行为有关的物理建筑与居民模型、网络建筑与人的交互以及智能控制模型之间的复杂相互关系；3)在斯坦福校园和谷歌办公园区的试验台建筑上对模块和整个BI5M系统进行经验测试和验证。本研究将测量(地理空间建筑数据、能源使用数据)、动态(居民社交网络)和控制(增强的用户对即插即用设备、暖通空调、照明的控制)纳入BI5M系统。BI5M系统以建筑的网络建筑信息管理(BIM)模型为中心，将包含严格的系统工程，将探索跨网络物理领域的关系，并开发关于如何使用网络物理系统的科学原理通过居住者行为和智能控制来影响商业建筑能效的新见解。通过将物理建筑信息和居民与网络交互建模相结合，该研究旨在为商业建筑引入一种集成的人在环控制范式。除了用于商业建筑的试验台和经过验证的CPS系统(BI5M)外，该项目还针对以下方面的基础知识：将动态数据流和控制信息整合到静态建筑模型中所需的本体组件；居民的复杂社会空间结构；洞察建筑与人和人与人的互动如何影响居民的消费行为；以及利用对居民的能源使用、空间、社会和行为动态的投入的新控制模型。该项目的教育影响将延伸到参与者(学生、教师、试验台建筑中的谷歌员工)以及更广泛的学生群体，方法是将这项工作的关键见解整合到所有三所合作大学(斯坦福大学、佐治亚理工学院和哥伦比亚大学)的课程/项目中。项目组还将通过外联讲习班向在建筑物管理领域工作的从业人员/政策制定者传播成果。此外，该项目将通过一个多样化的团队，并通过与编程女孩非营利性组织合作，将项目数据集和工具整合到他们的活动中，从而扩大对计算机领域的参与。该奖项反映了NSF的法定使命，并通过使用基金会的智力优势和更广泛的影响审查标准进行评估，被认为值得支持。

Each year the nation spends over $400 billion to power, heat and cool its buildings. Moreover, buildings are a major source of environmental emissions. As a result, even a modest improvement in energy efficiency of the nation's building stock would result in substantial economic and environmental benefits. In this project, the focus is on improving energy efficiency in commercial buildings because this sector represents a substantial portion of the energy usage and costs within the overall building sector. Enhancing the energy efficiency of commercial buildings is a challenging problem, due to the fact that centralized building systems -- such as heating, ventilation and air conditioning (HVAC), or lighting -- must be synthesized and integrated with individual inhabitant behavior and energy consumption patterns. This project aims to design, analyze, and test a cyber-physical and human-in-the-loop enabled control system that can drive sustained energy savings in commercial buildings. It brings together expertise in computational building science, eco-feedback, network theory, data science, and control systems to integrate physical building information and inhabitants with cyber (building-human) interaction models to enable intelligent control of commercial building systems. Specifically, this project will: 1) design an integrated cyber-physical system (CPS), called Building Information, Inhabitant, Interaction, Intelligent Integrated Modeling (BI5M), aimed at reducing energy usage in buildings; 2) assess the complex inter-relationships between and across physical building and inhabitant models, cyber building-human interaction and intelligent control models related to energy conservation behavior; and 3) empirically test and validate modules and the overall BI5M system at test-bed buildings on Stanford's campus and Google's office park.This research incorporates measurement (geospatial building data, energy use data), dynamics (inhabitant social networks), and control (enhanced user control of: plug-load devices, HVAC, lighting) into the BI5M system. The BI5M system is centered on a cyber Building Information Management (BIM) model of the building, and will encompass rigorous systems engineering that will explore relationships across the cyber-physical domains and develop new insights for how the scientific principles of cyber-physical systems can be used to influence the energy efficiency of commercial buildings through both occupant behavior and intelligent control. By integrating physical building information and inhabitants with cyber interaction modeling, the research aims to introduce an integrated human-in-the-loop control paradigm for commercial buildings. In addition to a testbed and validated CPS system for commercial buildings (BI5M), this project targets fundamental knowledge on: ontological components required to integrate dynamic data streams and control information into static building models; complex socio-spatial structures of inhabitants; insights into how building-human and human-human interactions impact inhabitant consumption behavior; and new control models that leverage input on the energy usage, spatial, social and behavior dynamics of inhabitants. The educational impacts of this project will extend to participants (students, faculty, Google employees in the test-bed buildings), as well as a broader student population through the integration of key insights from this work into courses/projects at all three collaborating universities (Stanford, Georgia Tech, and Columbia). The project team will also disseminate results to practitioners/policy-makers working in the building management space through an Outreach Workshop. Additionally, this project will broaden participation in computing fields through a diverse team and by partnering with the Girls Who Code nonprofit to integrate project data sets and tools into their activities.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
