Dr. Hom Bahadur Rijal is a Research Professor and Dean of Graduate School of Environmental and Information Studies at Tokyo City University, Japan. He has MEng and PhD in architectural engineering from the Kyoto University, Japan. He was employed on a project developing an adaptive algorithm of window opening to predict the thermal comfort and energy use in buildings at Oxford Brookes University. He has a well established research track record, with over 100 publications in journals, 14 chapters in books and co-edited three books. His major expertise is adaptive thermal comfort and occupant behaviour within building. In particular, he measured the thermal environments in traditional vernacular houses in Nepal, looked at the thermal comfort of their occupants and made thermal simulations of them for each climatic zones of Nepal. He also received the Architectural Institute of Japan (AIJ) Encouragement Prize (2006), Most Cited Paper Award 2020 of Japan Architectural Review and AIJ Prize 2024 (Research Paper Division).
