Antony Wood has been Executive Director of the Council on Tall Buildings and Urban Habitat since 2006. He is chair of the CTBUH Tall Buildings and Sustainability Working Group. Based at the Illinois Institute of Technology, Antony is also an Associate Professor in the College of Architecture, where he convenes various tall building design studios. A UK architect by training, his field of specialism is the design, and in particular the sustainable design, of tall buildings. Prior to becoming an academic, Antony worked as an architect in practice in Hong Kong, Bangkok, Kuala Lumpur, Jakarta and London. He is the author and editor of numerous books and papers in the field, including the 2008 title “Tall & Green: Typology for a Sustainable Urban Future.” His PhD explored the multi-disciplinary aspects of skybridge connections between tall buildings.Ruba Salib was raised in Amman/Jordan and immigrated to Canada in 2002, where she earned her Bachelor degree from the University of Toronto, majoring in both architecture and fine art history and developing an interest in sustainable design and energy efficient buildings. After practicing for a year at an architecture firm in Jordan, Ruba pursued her Master of Architecture in Environmental Design at the University of Nottingham in the UK, with a dissertation topic on Natural Ventilation in High-Rise Office Buildings. A passion for sustainable design has led her to be actively involved in drafting green building guidelines for Jordan and the United Arab Emirates. Currently based in London, she is working on various small-scale and large-scale international projects at RSP Planet Design Studios; an architecture, planning and engineering practice headquartered in Singapore.
