Eighty-seven-billion square feet of floor space now stretches across 5.6 million commercial buildings in the United States, according to findings from the U.S. Energy Information Administration’s most recent Commercial Buildings Energy Consumption Survey.

While energy consumption data will not be released until next year, the survey found significant levels of growth within the U.S. commercial building sector – with the number of buildings jumping 14 percent and the amount of floor space climbing a tremendous 22 percent since 2003.

With more than 2.24 million buildings in its region, the South led the way in commercial development during the timeframe, followed by the West (more than 1.26 million) and the Midwest (1.23 million).

Historically, the survey has found increasing levels of energy consumption over time. But with commercial buildings being smarter now than ever before, it can’t be assumed this overall trend will continue. But not every building is a smart building. Nearly 20 percent of commercial buildings are old – built before World War II. And some old and newer buildings are downright energy hogs.

That’s why People Counting for Buildings can be an intelligent investment. People Counters unobtrusively analyze how a building’s occupants utilize the building as a whole as well as within individual spaces.

Over time, data trends begin to show times of consistently high and consistently low occupancy levels – down to individual meeting rooms.

That data powers Building Automation Systems to optimize notoriously power-hungry HVAC and lighting systems. When those systems are automated to align with actual building usage, significant dollars are saved and can be invested into other areas of a facility.
