Generally, when we think about BAS or system integration projects, they are for larger projects such as schools, office buildings, and hospitals that are 50,000 sq ft or larger. These larger projects have more complicated systems, higher energy usage, and can readily justify the investment in sophisticated controls.
However, according to the U.S. Energy Information Administration, these larger buildings comprise only 6% of the U.S. com-mercial building stock. Even looking in terms of floor space, buildings less than 50,000 sq ft comprise 50% of the total floor-space, which means that they, in turn, use about half of the total energy consumed by all commercial buildings.
