HVAC basics for energy management: controlling comfort, cost, and performance

HVAC systems are the single largest energy expense in most buildings, yet they are often treated as “black boxes” that only get attention when something breaks. This session is designed to help Energy Managers and Sustainability Professionals understand how HVAC systems actually work and how day-to-day operational decisions directly impact energy use, comfort, and cost.

This session provides a clear, practical overview of core HVAC concepts, including heating and cooling fundamentals, air distribution, ventilation, scheduling, and control strategies. Participants will learn how common components such as boilers, chillers, air handlers, rooftop units, pumps, and controls interact to meet occupant needs and where inefficiencies typically hide. Special emphasis is placed on understanding runtime, setpoints, occupancy patterns, and the role of building automation systems.

The takeaway is simple: you don’t need to be an HVAC engineer to manage HVAC energy effectively. With a strong foundational understanding, organizations can reduce waste, improve comfort, extend equipment life, and turn HVAC systems into a controllable, strategic asset.
