HVAC Technology Enhancements for Energy Conservation

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.
