Rating systems for counting buildings’ environmental performance

The building and construction sector is a key sector for sustainable development. In response to the demand for evaluation and management of buildings environmental performance several tools and methodologies have been developed and implemented to building construction aiming sustainable performance. The paper is focusing on rating systems analysis, comparison and implementationfor buildings environmental performance. Criteriafor rating systems evaluation are set, while the most representative rating systems such as BREEAM and LEED were implemented to office building in Greece. The building is located in the centre of the city of Thessaloniki.It is a new multiuse construction, in which the ground floor will accommodate a sales shop, the two first floors offices, and the later five residences. Our main goal was to quantify buildings performance by implementing simple, low budget measures of sustainability accordingto LEED and BREEAM rating systems guidelines.
