Step by step guide for using the EPC

Step by step guide for using the EPC Tool e. Central / North-West Croatia Regional Energy Agency – REGEA / Hrvoje Maras & Milka Hrbud

HOW THE TOOL WORKS AND FOR WHOM n. ZEB calculation tool is based on seasonal method of 13790 which is currently in use in some EU countries • Predefined values are used to simplify the process of data input and NZEB estimation • Primary target group are public authorities as potential users of the tool …. Although not a primary target group- architects/engineers can use this tool as well • Beside in English, tutorials are available in SLO, HUN, IT, CRO • TAKING COOPERATION FORWARD 2
