Mr. Simon Jones:

To answer the first part of the Deputy's question, people's awareness of ventilation and the discussion of ventilation have always been problems. It is an invisible thing, a natural thing we do every second of the day without thinking about it. Even getting people to be cognisant of the air we breathe is very difficult indeed. This pandemic has certainly brought that into focus but issues of indoor air quality and poor health are slow burners. They are not as dramatic as the pandemic so we do not see it. I apologise; what was the second part of the Deputy's question?
