Indoor Air Quality

Key technologies used today that affect HVAC operation include chillers, thermal storage, variable frequency drives (VFD), and variable air volume (VAV) systems. Because heating and cooling can represent between 40 percent and 60 percent of building operating costs (including maintenance items), HVAC retrofit decisions should not be made without considering all factors -- including indoor air quality (IAQ).
