The energy and climate concept of the flagship research institute of the University of Pécs is the result of a three-stage development. The prototypical structures and building services of the first two concepts were developed in line with the financial circumstances and grants and the rationalized third concept became an object for construction research. Through the expansion of the building services and energy supply systems, the building itself has become a ‘measuring apparatus’ for sustainable building construction.

The Szentágothai János Research Center in Pécs brings computer based building physics simulations to reality closer than ever. This high class building ads ground to several medical research programs and lectures, but it also gives a rare opportunity to improve computer simulations with its’ Building Management System (BMS from now on). The system does not only allow the complex building services system to be remotely controlled from a single computer, but also gathers important data related to the buildings’ physical performance, for example: room temperatures; air flow rates; geothermal pipe performance; and energy consumption of heat pumps. By comparing the results of a zone based building physics simulation model of the building, enhancement of the precision of the simulations and optimization of the actual buildings energy consumption can be done, by trying out different maintenance strategies.The first step is to build the computer model to be as precise as possible. In the zone based physical model, energy flows between zones, but the zones themselves often lack precise physical attributes, like energy loss through heat bridges. In this paper we will show how 2D finite element heat transfer simulations improve, zone base whole building simulations.

Due to negative environmental changes and the energy supply problems of the society the EPBD 2010/31/EU prescribes for EU member states to ensure that by 2021 all new buildings are nearly zero energy buildings. The Energydesign® research team of the University of Pécs has developed a research-design method applicable for building climate, energy, aerodynamic and architectural technology modeling of smart energy-plus buildings. This problem-solving matrix arranges the systematic structured planning process, calculations, complex analysis, dynamic energy-climate and computational fluid dynamics simulation control of buildings through a finite number of algorithmic steps. The description of the logged design steps is meant to be an instructional process-guide, the Energydesign Roadmap.
