The document outlines 6 main factors that affect energy use in buildings: 1) Functional factors like the building's intended use and durability, 2) Environmental factors such as seasonal changes, 3) Envelope factors relating to the building exterior, 4) Air conditioning factors such as refrigerant leaks or maintenance issues, 5) Energy source factors concerning the source of energy, and 6) Electrical system factors involving the building's wiring and systems. Maintaining buildings for their intended functions, environmental conditions, and systems is important to control energy use.
