In Turkey, the largest share in total energy consumption by sectors is in the residential
and services sectors and has been increasing in recent years.(URL-1) The amount of energy
consumption in buildings, heating or cooling needs vary according to climate zones. In this
study, it is aimed to reduce the cooling energy need of a building in Antalya, which is
located in the Mediterranean region, with roof insulation and to make cost analysis. Within
the scope of the study, flat and pitched roof prototypes were modeled and analyzed
separately. The roofs of the building prototypes modeled using the Design Builder energy
simulation program were insulated at different levels and the cooling energy requirement
values were determined. The initial investment cost, profitability and payback periods for
different insulation alternatives were calculated, results were evaluated. It was found that
47.39% of the annual cooling energy requirement can be saved with roof insulation in a
single-storey building in Antalya and the payback period is between 1.64 years and 8.23
years depending on the insulation thickness used. With this study, it was seen that there
is a great potential to reduce the cooling energy need with roof insulation in buildings
located in the Mediterranean.
