Welcome to IBPC2018! Healthy, Intelligent, and Resilient Buildings and Urban Environments! This conference will be jointly organized by Syracuse Center of Excellence in Environmental and Energy Systems, College of Engineering and Computer Science, and School of Architecture, Syracuse University. IBPC is the official international conference series of the International Association of Building Physics (IABP). It has previously been held successfully in Eindhoven, The Netherlands (2000), Leuven, Belgium (2003), Montreal, Canada (2006), Istanbul, Turkey (2009), Kyoto, Japan (2012), and Torino, Italy (2015). The theme of IBPC2018 is “Healthy, Intelligent, and Resilient Buildings and Urban Environments”. It will provide a forum for scientific, technological and design exchanges through multiple platforms: 1) presentations of original research and development work and findings, 2) demonstrations and exhibitions of innovative green building technologies, and 3) discussions of future challenges and opportunities. It will cover a wide range of research topics cutting across multiple scales of the built environmental systems ranging from nano-material applications, to micro-environments around occupants, to rooms and whole buildings, and to neighborhood and urban scales (http://ibpc2018.org/conference-topics/). The goal of the conference is to advance the collective understanding of the nature and behavior of the cyber-physical systems in these different scales, how they interact, and what can be done to optimize their design and operation for healthy, intelligent and resilient buildings and urban environments. Registration for the conference will open on March 1st, 2018. On behalf of the organizing committee, we cordially invite you to participate in this important event, and look forward to your contributions!
