Abstract
Several methods for complex assessment of building performance are available in Europe. The Czech Republic has followed the international group Green Building Challenge since 2005 and participated in the development of the international assessment framework SBTool. The Czech Technical University in Prague in cooperation with National Platform SBToolCZ and International Initiative for a Sustainable Built Environment (iiSBE) provides a localised national version of the tool called SBToolCZ for wide usage in building practice in the Czech Republic. This paper presents the Czech assessment methodology SBToolCZ, its structure, system of weights setting and form of final certificate. It also introduces one of the certified residential buildings – X-Loft in Prague – and describes the process of its certification and its main outcomes.
