Building HVAC Systems (Primary and Secondary Building HVAC Systems) AHU – Air Handling Unit Fresh air for ventilation AHU Primary systems Distribution systems Air transport Electricity Cooling (chiller) (or Gas) Heating (boilers) Gas Secondary systems Building envelope HVAC systems affect the energy efficiency of the building as much as the building envelope. In many situation even more!
