Controlled air renewal throughout the year through an air renewal system or automated windows for all building categories, except the Industry and Warehouse categories, is mandatory. In the MINERGIE® justificatory, specifications for the quantification of the expenditure of “small” ventilation systems (less than 1000 m3/h) are presented.
For the calculation of the energy expenditure of the larger ventilation systems, the ventilation-cooling tool according to SIA 380/4 is available. This tool will eventually replace the excel spreadsheet excerpt tables used so far. For now, both tools can be used for MINERGIE® justificatory.
