Residential buildings energy performance optimisation - façade openings and shading devices

Abstract

This paper presents a methodological approach to optimization of facade openings and shading devices on residential buildings in the city of Belgrade, Serbia, from the aspect of building’s energy performance. The research is carried out using digital simulation tools, simulating a selected type of residential building, varying the conditions of the urban environment in which the building is located, the size and geometry of facade openings, as well as the types of sun shading elements, taking into account the functional, financial and social aspect of their application on residential buildings in Belgrade. The dimensions and types of openings and shading devices are evaluated based on the simulation results, taking into account differences in individual apartment’s energy needs based on orientation and the position in the building. The analysis of the obtained data and their mutual synthesis leads to recommendations for the design of residential buildings of the observed type for the climate conditions of Belgrade.
