Investigation of the effects of using solar energy on the energy performance of buildings

This research was concerned with the energy analysis of the Narlıdere Nursing Home and Rehabilitation Centre (NNHRC) in İzmir, Turkey, chosen as a sample public building. The Centre was run as a nursing and rehabilitation centre for the aged and it included a geriatric division operating as a hospital. The Centre was analysed using the actual energy consumption data derived from several energy audits. Solar energy is an important technology when considering sustainability and in this study, it was calculated how much the energy load of NNHRC would be reduced if PV Panels were used. The difference between the current situation and that once a 500 kWp PV panel system was installed was discovered. According to the results of the study, with 500 kWp PV panels placed on the roof, approximately 21% of the facility's electricity needs could be provided by these panels. With the use of PV panels, a 2.44% reduction in primary energy and a 4.28% reduction in emissions could be achieved, and an improvement of 2.43% in PER.
