Implementation of Heat Flux Measuring Methods for Heat Transfer Coefficient Determination of In Situ Construction

Subjectively, to verify the human perception of the state of satisfaction with the environment it is necessary to use objective methods. One of these methods is the heat flux measuring method. This paper points out the risk factors that affect the heat transfer coefficient H through building structures that are necessary to determine the projected heat input of the building. At the operation stage, the aforementioned structures are affected by environmental factors (noise, artificial lighting, heat sources). This changes the suggested value H_c to the real value H_r, which is documented by the measurements. The rate of change of the H value is given by the correction “K”. According to the measurements the value obtained can be corrected from 0.08 to 0.25. The final values of the heat transfer coefficient were generalized in the equation and the value of the building energy category within the energy certification of buildings was determined. The result is a methodology for the optimal determination of H values for hazard prevention.
