ABSTRACT
This study focuses on the energy savings and economic impact of green roof systems applied to Central Bodrum, a district in southwestern Turkey. Energy savings of the buildings were evaluated based on the added thermal resistance on the roofs and corresponding heat transmission through the roofs. Four different scenarios, two without green financing and two with green consumer loans for retrofitting financed by the central government via the state-owned banks, were studied. The economic impact of this activity on the economy is estimated based on sectoral employment multipliers for a period of 10 years. Based on the scenario analysis and the priorities of the Turkish economy, given the employment benefits and energy savings which would reduce the energy demand in the area in the peak season, we propose that the government implements green consumer loans for retrofitting through the state-owned banks.
