Our office is authorized to perform energy overviews and energy certificates, for buildings with simple and complex technical systems, in other words for all buildings. Authority number issued by the Ministry of Environmental Protection, Urban planning and construction is P-304/2013. We issue energy overviews and certificates for existing and new buildings for all regions in Croatia. Energy overview (is done only for existing buildings as a prerequisite for certificationand it consists of:
Data collection of information regarding the building
Implementation of control measurements if needed,
Analysis of energy and water consumption over the last three years
