Research on improving the energy performance of residential buildings

The research focuses on the improvement of lighting systems and the impact of photovoltaic applications on energy efficiency in buildings, aiming to increase building energy efficiency in response to global challenges such as population growth and urbanization.The study, conducted in Antalya, located in the Mediterranean Climate Zone, evaluates the impact of upgrading the lighting system and integrating photovoltaic panels in three selected blocks within an island-based settlement.Energy efficiency assessments cover a variety of factors such as building location, orientation and energy use scenarios including both natural gas and electricity for heating.Hourly analyses using DesignBuilder simulation and PVsyst software show that by improving the lighting systems, annual energy savings of up to 33.00% in the energy consumption of the lighting system and 7.20% in the total energy consumption of the buildings can be achieved.In addition, it is seen that up to 14% of the energy demands can be met with the integration of PV systems into the buildings.These findings underline the significant potential for reducing energy expenditure and environmental footprints.By demonstrating the effectiveness of an island-based strategy for improving building energy efficiency, this study extends the scope of energy saving initiatives from floors, spaces and buildings to an island-based approach.
