Mechanical ventilation systems often include heat recovery which vastly reduces the heat demand of ventilation, they can reach values of more than 80% recovery but we assume here just 70% and that just 40% of the systems have such a system.

If I did not make a massive mistake the result is that the energy cost would be around 15 Euro per person and year to have really good air in every non-residential indoor space or 5 Euro per person and year when limiting it to places which already have mechanical ventilation systems.
