Influence of upgrading glass wall inside of building on thermal comfort

Abstract

As we progress toward net zero energy - efficient solutions, it becomes increasingly important to have more quality CFD models on thermal comfort and indoor environmental quality. Based on experimental data collected, there was an analysis of statistical data and variation of mathematical CFD models. The proposed models are built into a numerical code of the commercial software PHOENICS. While investigating, special attention was paid to the influence of production and dissipation terms of turbulent kinetic energy due to the fluctuation of body forces. Parametric analysis was conducted on the the basic model, which is characterized by the fact that the turbulent model and heat transfer by radiation model is built-in. A statistical analysis of a complex array has been conducted, so additional statistical indicators have given the right information about the model quality. Based on the results of the numericals models, it was shown that the variation of transparence in a model of radiation and coefficient of dissipation in turbulence model have a dominant role on local parameters in PMV indicators of thermal comforts models.
