Computational numeric simulation for thermal bridge evaluation can be considered a state-of-the-art technology in recent times. The current progress of both computational power and program development allow for fast evaluation of two- and three-dimensional thermal bridges. Even the evaluation under transient boundary conditions can be conducted. However, architects and planners do barely use thermal bridge evaluation tools, but often fall back to standard solutions for building joints. Moreover, due to time- and cost-pressure consultants, who were capable of evaluation of thermal bridges, are - if all together - only requested in case of risk, danger or damage. This setting can be regarded as a lack of opportunity for architects and planners to exploit new fields of work. Furthermore, typical standard solutions might not render the optimal solution in any and every case.
In this context, the present paper describes a set of new developments and case studies of application of a numeric thermal bridge simulation tool for building planners. While the development of such tools needs expertise in numeric mathematics and thermodynamics, this is not necessarily true for the application of the methods of thermal bridging simulation. Recent developments in simplifying both data input and fast and save result generation are described, including the opportunity to add sloped shapes and rounded surfaces to thermal bridge models. The latter was - until recently - a major setback in opening thermal bridging tools to architects and building planners.
