Laura,
Good day!
We do not need to install new ventilation systems in our schools. If you remember the energy crisis from many years ago, the school districts around the country were told to close the fresh air intakes in the Air Handler Rooms of the school buildings and this would allow the air conditioners to not work so hard saving energy. What this really did was recirculate the same air in the school, not allowing any fresh air in, which created sick buildings. At the time I was a manager in the Safety Department of one of the largest school districts in our country. People have short memories.
Love your show.
Take care,
Jerry
