BUILDING DENSITY IMPACT ON FINAL ENERGY CONSUMPTION FOR ARTIFICIAL AND AUTOMATIC LIGHTING CONTROL SYSTEM IN THE SPORTS HALL – NUMERICAL CASE STUDY ANALYSIS

Abstract

An increasing number of new buildings equipped with modern and energyefficient thermo-technical systems contribute to society’s efforts to make urban environments more sustainable shortly than they were before. Despite this, the applied methods have negative consequences that slow down this process. On the (concrete) example of the sports hall, by analyzing the consumption of final (electrical) energy for artificial lightning, this paper pointed out the negative effects of shading in buildings – phenomena that arise as a consequence of accelerated urbanization, without more detailed planning prediction bases. To create this numerical study, the software packages EnergyPlus and Google SketchUp were used, which communicate via the Legacy OpenStudio platform. Based on the conducted simulations, it was concluded that the consumption of final (electrical) energy for artificial lighting can be increased over 2.59 times, depending on the next parameters: the shape factor and orientation of the building, technical characteristics of lighting, and windows, spatial planning and urbanization, etc. For the sake of creating sustainable cities, energy-eco projects should not focus only on individual buildings in the future, i.e. isolated cases. The problem should be looked at more broadly, taking into account at least the immediate environment, i.e. “communication” of the analyzed building with its surroundings.
