The article is devoted to the problem of design and fabrication of joints in contemporary wooden architecture. The CAD/ CAM design methodology results in new production and assembly methods used in the creation of novel structural systems. Connections used in structures are often derived from traditional carpentry connections used in a new way. They are reinterpreted and adapted to their new role in new structural systems. The article presents the results of an analysis of three experimental pavilions conducted in the context of the types of element connections used in their construction. Carpentry joints in traditional architecture were used and fabricated with technologies available at the time and were developed and used in post-beam constructions that utilize large, widely-spaced wood to provide structural support to the building. Timber frame technologies were dependent on mechanical connectors (nails, screws, shear plates, nailed plates). Digital era technologies provide new ways of joining elements according to new structural systems.

The second part of the article discusses the assessment of extreme weather conditions on architecture in the era of climate change with the aid of CFD analysis tools. Computer simulations such as CFD have opened up new possibilities for design and research by introducing environments we can manipulate and observe. The article presents two case studies of high-rise buildings: Plac Unii (2013) and Q22 (2017) located in Warsaw, showcasing the increasing role of new technologies, particularly CFD simulation tools, in studying the aerodynamics of urban environments. The paper includes CFD wind studies of the buildings and their urban surroundings performed in Autodesk Flow Design.

The article discusses the impact of air flow on architectural form. Climate change related extreme weather events expected in the near future pose a significant challenge and require the integration of building aerodynamics in the architectural design process. Windage analyses carried out at an early design stage are an essential tool in the process of searching for the architectural form of buildings designed to resist extreme wind events. Due to the breadth of the topic and the limitations of the article’s length, the text has been divided into two parts. The first part of the article presents early concepts of building aerodynamics, historical methods of wind flow analysis based on observations and physical models, as well as the use of CFD (Computational Fluid Dynamics) analytical tools. The article reviews and compares three wind analysis tools based on the CFD methodology: Autodesk CFD, Autodesk Flow Design and Butterfly (Ladybug plug-in). The results of an original study of the aerodynamics of the building of the high-mountain meteorological observatory on Śnieżka using the Autodesk Flow Design software were also presented as a case study of a facility located in extreme weather conditions and designed with a clear reference to aerodynamics. The second part of the article discusses the methodology of research on the aerodynamics of high-rise buildings and the impact of wind load on the architectural form of buildings. Case studies of two high-rise buildings located in Warsaw, made using the Autodesk Flow Design program, were also presented.
