AbstractPhenomenon of today′s era is lowering overall energy performance and greenhouse gas emissions. European Union and its members came from an “uncontrollable” fossil fuel usage to an era of dependence reduction from fossil fuel usage. EU industry is now in era of utilizing renewable energy sources. Construction industry is responsible for 40% of total energy performance of EU; hence the great emphasis on energy effective design on new buildings as well as importance on energy effective renovation of already constructed buildings. Effort on lowering total energy performance in construction industry has signed on research on new project solutions, new insulation materials and new building services technologies which are maximizing energy gain from renewable energy sources. Simulation software and different engines are more than helpful tool when predicting building thermal behaviour. That is why simulation software is used more often in the process of designing energy efficient buildings or in the process of energy performance optimization of existing buildings. simulation and analytics itself, is dealing with simulation of chosen buildings (family houses) on heating demand based on the newest knowledge of constructions and materials. Results of heating demands of different family houses were confronted against heating demands calculated according national standards – using non-variable conditions. Next, the differences between two calculation approaches were characterized in percentages.

Lower Heating Value

In Europe, primary energy consumption in buildings accounts for up to 25–40%, depending on the climate conditions. Space heating and Domestic Hot Water (DHW) contribute significantly to this energy consumption. Among the most common sources for heat generation in these appliances is natural gas. Condensing boilers can surpass the 100% energy performance over the lower heating value, if the operating conditions enable the water vapor in the exhaust gases to condensate. Consequently, optimizing the operating parameters of condensing boilers is necessary to decrease fuel consumption without hindering water heating needs. The present work presents an experimental approach to the operating parameters of a condensing boiler that works with natural gas. The aim is to develop a theoretical model that relates the energy performance to the water temperature set by the final user and the excess air set by the maintenance staff.
