The idea to analyse the heat transfer between flats through internal walls is based on long-time question: ?How much will the heating demand of a flat increase if the neighbouring flat is not heated or uses a attenuation heating mode during the day??. It is a very complex question due to the complexity of the task and there are many factors that influence the heat transfer between flats. The goal of analysis is to find out how the material of inter-flat wall affects the heat transfer between flats by using different heating modes. Using the simulation tool is the way to perform this analysis. We selected the simulation tool DesignBUILDER.
The first part of results describes the situation in new apartment buildings where not all flats are sold or inhabited. On the base of the results it appears that the best would be to build the internal walls between flats with low coefficient of thermal transmittance (e.g. 0.55 W/(m2.K)). On the other hand, it is needed to say that these situations (unheated flat during heating period) are not often happen in real life or they take a short time (e.g. only one or two heating periods). The second part of results describes common situation from real life when residents use the thermostatic heads to decrease the temperature in flat during their absence (work, school and so on). In our case there was considered the decrease of temperature on value 15°C in time 08:00-16:00 every day during heating period. The residents of apartment house that heat their flats on temperature 20°C during whole day are afraid that their heat demand for heating will increase shortly. On the base of results from energy simulation we can say that the average increase of heat demand for heating of flat is 2% through internal wall between flats, and 4% through ceiling and floor together. |
