This thesis presents the development and application of Life Cycle Assessment (LCA) based home rating model for residential buildings in Izmir. It aims to develop building performance assessment within a single application. This new application supports various considerations throughout the building.s life cycle in relation to performance domains such as site ecology, energy consumption, material selection, lighting availability, transportation and the rest of the performance indicators. It is intended to encourage initiatives toward achieving better housing performance. ATHENA Canadian Software tool has been selected to calculate quantitive values for energy consumption, solid waste emission, air pollution index, water pollution index, global warming potential, weighted resource use. Then, thirty performance indicators, which were selected from the review of existing evaluation models has been grouped under four building life cycle stages, site selection, construction, operation, and demolition. The weights of each category and indicator has been calculated, and converted into a credit score. Then, the performance grades are divided into five levels, (excellent, good, average, below average and poor) and evaluation criteria are suggested based on statutory performance value.
