Design problem-solving: A theme for critically debating the integration of building thermal physics and architecture design

This thesis proposes to theoretically and critically examine how building thermal simulation tools might be integrated throughout the whole building design process considering the knowledge and thinking involved in building thermal physics as well as the knowledge and thinking involved in architecture. It focuses in understanding both worlds to discuss how they can potentially interface with each other. In order to fully acknowledge the interdisciplinary character of this type of research, a critical and theoretical discussion is undertaken in opposition to the dominance of empirical studies and practical propositions that have been currently used to deal with the issue of integration. The proposed critical and theoretical reflection is based on a critically constructed structured methodology centred on the theme of design problem-solving. Design problem-solving is initially discussed in a domain independent basis setting up the premises for commonalities and differences between the two professions to be debated. Individual discussions in design problem-solving are presented for building thermal physics as well as building design, analysing the different paradigms they subscribe to when designing. Paradigms are contextualised within specific worldviews and related to representation systems, practices and computer tools used by each group of practitioner in their everyday activities. Contrasts between these two debates are outlined and potential scenarios to critically reflect on integration are proposed. The outcomes of the research suggest that there is no single solution for building thermal simulation tools to be better integrated throughout the whole design process. The best solution needs to be critically constructed every time a new problem arises. In order for that to happen, building physicists and architects education needs to be improved for the two professionals to be able to properly communicate and effectively construct a joint practice. Additionally, simulation tools need to be designed with configurable interfaces that can address the idiosyncrasies of each practice together with the peculiarities involved in dealing with each specific problem at hand.
