Hello to everyboty and Merry Christmas,
I have to make the flush out in a building which is mostly a Warehouse, that will be regularly occupied, with mechanical ventilation but no air conditioning.
Inside the warhouse there will be a smaller office construction, that counts with it´s own mechanical ventilation and air conditioning system.
Do I have to flush out the hole builiding including the warehouse or is it enough to flush out the office spaces?,
Thank you
