Energy performance indicators developing

Abstract The building environmental assessment systems and tools used over the world were the base of new system development for Slovak conditions. The proposed fields are site selection and project planning; building construction; indoor environmental quality; energy performance; water and waste management. The fields and indicators were proposed on the bases of available information analysis from particular fields of building environmental assessment and also on the base of our experimental experiences. The aim of this paper is presented developed building environmental assessment system oriented to energy performance and the significance weight determination of mentioned field. Percentage weight of fields and indicators was determined on the base of their significance, according to mathematical method.
