Understanding where we can gain and lose energy in an HVAC system isn’t always a straight-forward endeavor. Energy loss can stem from any number of reasons, like leaking duct systems or neglecting to lower the system demands during hours where the building is unoccupied. Considering this, the number of variables that go into maximizing energy efficiency can be daunting to say the least. That’s why the National Renewable Energy Laboratory has created a comprehensive checklist of the myriad of aspects of a building where we can look to save energy. It starts with air handling, and delves into other details as well, like boiler systems, chilled water systems, and building envelope components.
