Frequently asked questions

Everything you want to know

The Finnish Ministry of the Environment decree 1009/2017, section 9. The numbers are taken from the text of the decree (Edilex). Always check the provision that applies to your project. Read the full rules

A scan or photo (JPG or PNG) with the room names on the drawing, one image per storey. If the areas are printed on it, they are taken over.

They are measured from the dimension lines, but how accurate that is depends on the drawing style. Always check them and adjust them in the table.

Then nothing is guessed: the room does not count until you choose its function yourself in the check step.

The calculation gives the flow rate required per room under the regulation. Duct sizing, the design of valves and noise are not covered; you calculate those yourself.
