Coronavirus Prevention: ASHRAE Guidelines for Building Ventilation
Reducing the supply of direct outdoor air, when needed, is the aim of most modern HVAC engineering. Depending on the time of the year, increased airflow can result in an increased workload on the heating or cooling system. In this case, the heating costs are especially high during the hot summer days and high cooling costs during the cold winter days.
However, ASHRAE provides new HVAC ways to help in controlling or preventing the spread of the coronavirus in your building, during and after the pandemic. ASHRAE suggests that buildings should keep outdoor airflow at a maximum. This way, indoor air recirculation is reduced as well as the chances of spreading the virus through indoor air recirculation.
