Dynamic building energy performance modeling is becoming increasingly important in the architectural, engineering, and construction (AEC) industry because of the sector’s significant environmental impact. For such analysis, a climate file representing a typical meteorological year (TMY) is needed, including hourly values for the most important weather-related parameters. However, TMY shows little resemblance to the future of the particular location where a building has been used for decades. Therefore, using predicted future climates during building design is unfortunately rarely practiced, potentially undermining the strategies that should be the fundamental basis of the design. To explore this question, our study compared the heating and cooling energy consumption, indoor thermal comfort, and summer overheating potential of a selected building for three distinctive European climates, in Hungary, Portugal, and Lithuania. All of them were changed according to the IPCC RCP4.5 scenario, and were examined for the present, the 2050, and the 2100 scenarios. We also tested adaptive clothing to evaluate the indoor comfort parameters. The results show a 10% increase in heating and cooling energy use for the same construction and location between 2020 and 2100. The continental climate of Budapest is the most threatened by summer overheating, with an increase of 69% for the ODH26 indicator. A more balanced warming for Lisbon was found (23%), and moderate changes for the city of Kaunas (a 153% increase from a very low baseline).

The construction industry is currently one of the least digitised. However, due to recent technological developments, building information modelling and management (BIM) systems are increasingly being used to increase the efficiency of constructions and sustainable use of resources and increase the energy efficiency of buildings. In the case of new constructions or building renovations, properly designed hygrothermal behaviour of building materials, elements and structures are unavoidable to achieve the objectives mentioned above. Therefore, we can ensure the comfort of our users and healthy living space.BIM is the most suitable and widespread method for digital management of building stock and related data and integration. With the possibilities offered by BIM, it is possible to integrate building physical modelling right into the architectural design process. However, with standard BIM systems, we cannot embed detailed material properties, weather, or the effects of the natural and built environment in the BIM model for heat and moisture transfer (HAM) modelling for hygrothermal performance evaluation at present. Furthermore, the data exchange process is one-way mainly and unregulated between BIM and numerical simulation tools.In the presented paper, both a Closed BIM and an Open BIM based workflow are presented to bridge the gap between BIM and hygrothermal modelling of building components and constructions, that can contribute to the design of sustainable, economic and hygrothermal optimal building constructions and also could be a basis for artificial intelligence-based optimised design solutions.

In this study, a BIM-based building physics modelling of a ventilated façade of a multistorey residential building was made to obtain the thermal performance of the construction. The workflow is performed in an open BIM environment using Archicad to create the model and Comsol Multiphysics for performing the numerical simulations. After creating a suitable workflow and performing the finite element simulations, we determined the thermal impact of the supporting brackets and the dowels securing the thermal insulation, respectively. We also calculated the thermal performance using simplified methods according to standards to evaluate the BIM-based results.

For an architect with many years of experience yet few projects to his name Zumthor's impact on the architectural world is immense. This is due more to an approach to the design process and working culture, an intuitive approach to publicity, and professional ethics. The publication of "Thinking Architecture" nearly twenty five years ago examining the connection between process, 3d modelling and architecture as a whole helped to define this architect's path towards design as a whole.
