Following the success of the first version, The conference represents and analyzes Parallelism as a way to understand and reveal the mechanism behind the interaction between Architecture, Environment and Computing techniques. The high pace of technology, particularly after the long wave of industrialization and artificial intelligence, has altered the way we see the universe. The human contribution to almost every field became passé, and now it is more about the synergy between the human and the technology. The conference represents and analyzes Parallelism as a way to understand and reveal the mechanism behind the interaction between Architecture, Environment and Computing techniques. This conference unveils the new trends of architectural technologies and computational thinking that can adapt and improve finding a complex digital fabrication, augmented reality, and intelligent environment. The conference represents an important forum for computational and digital architecture research that reconciles parallelism in different architectural and computing discourses. It also provokes discussion in state-of-the-art themes and topics, such as high performance computing, big data, advanced systems and interfaces, ubiquitous computing, as well as advanced fabrication technologies and tectonics. The conference also includes within its scope a number of workshops and technical sessions. The second version of the PACT Conference is to be organized by the University of East London (UEL) in collaboration with the International Experts for Research Enrichment and Knowledge Exchange (IEREK)institution. The research, that is the main part of the debate, is to be contributed with and discussed over a number of sessions that are introduced and initiated with keynote lectures. The lectures are to be given by well-known speakers and continued by the exchange of knowledge and ideas between the researchers themselves.
