Heat and Mass Transfer in Building Energy Performance Assessment

Original language description

Dear Colleagues, The building industry is influenced by many factors and trends reflecting the current situation and developments in the social, economic, technical, or scientific fields. One of the most important trends is the effort to minimize energy demand, which can be achieved by promoting buildings with better thermal insulating capabilities of their envelopes and better efficiency of heating, ventilation, and air conditioning systems. Any credible assessment of building energy performance includes the identification and simulation of heat and mass transfer phenomena in both the building envelope and inside the building. As the interaction between the design elements, changes in the climate, behavior of different users, effectiveness of heating, ventilation, and air conditioning systems and lighting is not straightforward, the assessment procedure may present a complex and challenging task. The simulations should involve all factors affecting the energy performance of the analyzed building. However, the appropriate choice of physical model of heat and mass transfer for different building elements is not the only factor affecting the output of building energy simulations. The accuracy of the material parameters applied in the models as input data is another potential source of uncertainty. For instance, neglecting the dependence of hygric and thermal parameters on moisture content may affect the energy assessment in a significant way. Boundary conditions in the form of weather data sets represent yet another crucial factor determining the uncertainty of the outputs. In light of trends in climate change, this problem is becoming even more important.
