HVAC very well may be the largest energy user in a commercial building. When you add heating, cooling, and ventilating together and treat them as a single system (as they generally are), it is 45 to 70% of the building’s energy use. For comparison, lighting is usual just 10-30%. Of course a lot depends on climate, building type, and building usage, but HVAC should be a major retro-fit target for those who are concerned about energy conservation.
