This aim of this thesis was to contribute to the architecture field by making knowledge about insulation available to architects in an easy and informative way. If the information regarding thermal insulation is shared in a way that is accessible and understandable between the professionals, there is a chance to reduce energy consumption by 15-20%. Therefore, it is necessary to reduce their energy consumption by spreading the best practices in terms of thermal insulation across Europe. Secondly, our aim was to expand on existing knowledge of how architects perceive and use visual information in their profession by conducting qualitative and quantitative research to find more about our chosen phenomena. Surveys, interviews and workshops provided us with the information about architects’ needs and preferences for a digital platform, but also information regarding their perception and behaviour. Results show that architects are naturally driven by visual factors that stimulate their creativity and willingness to use the platform and acquire knowledge more effectively. Even though architects do not like to read technical material, they would prefer to have access to different levels of information and go deeper within the knowledge if needed. By drawing inspiration from those insights and following the theories of Human Computer Interaction, interaction design and information architecture, we developed a prototype of the platform that provides architects with the knowledge regarding thermal insulation in the classical buildings. The usability testing of the prototype provided us with data that highlights the strengths and flaws of the prototype. Based on the data, we proceeded with the development of the final prototype of a website with information regarding thermal internal insulation of classical buildings.
