Dynamical Thermal Analysis

Due to progressive computational dynamic 3D thermal analysis tools building structures may be subject of energy optimizations in early design phases. In sharing the architects 3D BIM (BIM - Building Information Modeling), approach, dynamic thermal analysis enables to optimize e.g. winter and summer energy balances, specific requirements of spatial temperature and humidity as well as alternative scenarios for invest, operating and maintenance costs of building and utility systems. Looking into holistic engineeered energy alternatives generally will lead to miminizing of affordings for firsthand and annual costings oft the overall utility systems, as well as minimizing the ecological footprint of the project improving sustainability aspects. Digital basis of the thermal analysis are integral 3D-modelings, defining necessary information towards e.g. climate and solar site conditions, volumetry of design, thickness, material attributes and energy values of building components. Contrary to rough linear calculations used in common ENEV or DIN regulations (german standards towards approving projects towards energy aspects in permission procedure), dynamic calculations are based on very individual and detailed project conditions. Important for the more precise dynamic calculations is the specific site data in terms of topography, day based annual ranges of temperature, solar gains, wind and rain. Important questionnaire of dynamic thermal analysis are:

      Definition of heating and cooling loads
      Analysing of comfort zonings in terms of temperature / humidity 
      Optimization of building utility systems

      Optimization of building shell systems

      Calculations towards EnEV-requirements

      Optimization of invest, operating and maintenance costs
