Increases in a distance of blurb buildings have outpaced increases in a series of those buildings over a past decade, according to EIA’s Commercial Buildings Energy Consumption Survey (CBECS). EIA’s CBECS is a usually nationally deputy information collection for building characteristics and appetite use in blurb buildings. Information about a blurb building batch in 2012 is now being released, and energy-use information is approaching after this year.
CBECS estimates that there were 5.6 million blurb buildings in a United States in 2012, totaling 87 billion block feet of floorspace. This turn represents a 14% boost in a series of buildings and a 21% boost in floorspace given 2003, a final year for that CBECS formula are available.
Newer buildings tend to be incomparable than comparison buildings. The normal distance of buildings assembled before 1960 (26% of a blurb building stock) is 12,000 block feet; buildings assembled between 1960 and 1999 (55%) normal 16,300 block feet; and buildings assembled in a 2000s (18%) normal 19,000 block feet.
Average building distance has increasing within a few buildings forms in particular, reflecting changes in consumers’ needs and wants. Four building forms showed a statistically poignant boost in building distance when comparing buildings built before 1960 with those assembled in a 2000s:
- Health caring buildings are removing larger, many expected to accommodate a needs of a race whose normal life outlook continues to increase.
- The distance of camp buildings increases almost opposite vintages. Growing numbers of both convenience and business travelers led to a construction of incomparable hotels.
- Retail (other than selling mall) buildings—a subset of a trading category, that includes malls—are larger, expected a outcome of a trend toward big-box stores.
- Religious ceremony buildings are also larger, presumably attributable to a flourishing series of megachurches, that have turn some-more renouned in a United States over a past dual decades.
The South’s share of new buildings exceeds a share of a U.S. race (the South comprises 37% of a race though 46% of new buildings). Almost half of all blurb buildings assembled given 2000 were built in a South, that gifted a fastest rate of race expansion opposite all census regions over a 2000-2012 period. These new buildings are 32% incomparable than those assembled before 2000.
