Learn about the most common HVAC systems and equipment, along with energy-related components and controls. occupants because the majority of building energy goes to conditioning the air that occupants breathe. To achieve this, the systems need to transfer heat and moisture into and out of the air as well as control the level of air pollutants, either by directly removing them or by diluting them to acceptable levels. Moisture control – water vapour in the air can be deposited within the envelope by condensation and cause serious health, durability, and performance problems 2.
