Application Driver: Improve Indoor Air Quality for Students and Teachers 

 The American Society of Heating Refrigeration and Air-conditioning Engineers (ASHRAE) guidelines call for a minimum of 6 Air Changes per Hour (ACH) for classroom ventilation. With that increase in ventilation air, required heating capacity could double or triple. School districts are turning to Energy Wall to add the benefit of increased ventilation without increasing the heating capacity of their HVAC systems.
