Building Characteristics

The amount of energy a building uses is determined by a number of factors. These include:

• Type and function of building
• Size of building
• Efficiency of building equipment and systems
• The number of people in the building and its hours of operation
• Operation and maintenance practices
• Age and construction characteristics

A new building will not necessarily use less energy than an older building, just as a large building may not use more energy than a smaller building, based on the other factors mentioned.   It is important to view these building energy statistics in context with the function, use, and characteristics of each building.

Energy savings can be gained from virtually all buildings, through improvements in operations or re-investment in more efficient building components (lights, windows, heating and cooling equipment, etc.).
