These relationships have the ability to positively or negatively impact health and wellbeing. This course explores the ways in which HVAC systems can contribute to wellbeing and focuses on indoor environmental quality (IEQ), holistic HVAC system solutions, and the WELL concepts of Air, Thermal Comfort, and sound.
