In this study, in terms of urban design, an exergy analysis of Mavisehir mass housing area in Izmir, Turkey is carried out based on spatial properties, shadow effects, wind effects and local climate to understand the importance of design strategies. The exergy analysis is applied with broad consideration covering the heat loads of the separate buildings for winter and summer. When the exergy results of Mavisehir I and Mavisehir II are compared it is found that Mavisehir II has less exergy by fuel and exergy load values. This may result from different design strategies in Mavisehir I where the same buildings and villas between residential buildings are located according to sea view, whereas in Mavisehir II, there is a heterogeneous pattern with various forms and heights of the residential buildings. It was also discovered that exergy efficiency of the area is 4.20% and the exergy flexibility factor is 19.3%.
