Evaluation of vegetated roofs in terms of sustainable performance

Vegetated roofs are an important component used in architectural design as part of the sustainability movement. However, difficulties arise over time in such roof arrangements and they cannot satisfy sustainable characteristics in our day. For this reason, this thesis primarily discusses the topics of sustainability in architecture and sustainability in vegetated roofs, under the concept of sustainability. Later, it examines vegetated roofs typology and the advantages of their effective usage. As a result of all examinations, the vegetated roofs' sustainability performance is demonstrated. Research is carried out regarding what qualifications under which factors are needed to ensure sustainability of vegetated roofs so as to achieve such performance. In conformity with the fact that vegetated roofs with these qualifications exhibit high performance, suitably selected examples are detailed. A detailed control list is created in relation to vegetated roofs, aiming to control aforementioned qualifications under certain variables. With the purpose of examination using this control list, 11 buildings from İstanbul with vegetated roof characteristics are selected, examined and the results announced.
