Renewable energy sources-integrated refurbishment approach for low-rise residential prefabricated building in Belgrade,Serbia

Abstract

The refurbishment of the existing housing stock has a twofold aim: to decrease consumption of fossil fuels and to reduce the CO₂ emissions. The main focus of the presented paper is the evaluation of the integrated design approach applied in scenarios for refurbishment of the prefabricated residential multi-apartment building. The criteria used in searching for the best approach to the renewable energy sources-integrated refurbishment were minimized energy loads, minimized CO₂ emissions and improved indoor environment quality, health and comfort. After in-depth environmental analysis, a series of energy efficiency improvement measures were implemented, as a comprehensive optimization of the building’s envelope structure, natural and mixed ventilation and source energy delivery. The building’s dynamic behaviour and energy efficiency have been analysed and optimized by the building performance simulation and PV panels’ integration for the typical meteorological year of Belgrade, Serbia. Energy refurbishment should be approached in an organized, pragmatic and interdisciplinary way. Hence, the focus should be not only on the latest leading-edge technology, but on the synergy of different practices and principles in order to ensure the path to sustainable development and achieving desired objectives.
