The Cost of Fresh Air
Numerous studies have shown that increased outdoor ventilation rates improve our health and productivity while reducing the transmission of germs such as airborne virus and bacteria. One study concluded that doubling the ventilation rates in buildings has the same effect as the flu vaccination.
Every time the outdoor ventilation rate is doubled, we reduce the concentration and therefore the transmission rate of all indoor contaminants by 40% to 50%.
But the cost of introducing fresh air has usually meant that we have designed HVAC systems with the minimum outdoor air to comply with the standards.
However, the answer lies in energy recovery.
If the mandatory 10 litres/sec per person of fresh air costs $30.00 per annum, doubling this will consequently become $60.00 per person. But if energy recovery was installed, it is possible to introduce 20 litres/sec per person for a cost of $18.00 per annum.
