Demographics: Changes in Types of Heating and Cooling Equipment, 1995 - 2003

Malls are no longer included in most CBEC’s tables, therefore some data is not directly comparable to past CBECs. The data may imply that malls use more individual space heaters and individual air conditioners than other commercial buildings.

Note(s): 1 Heating and cooling equipment percentages of floor space add to over 100% since equipment shares floor space. 2 Malls are no longer included in most CBECs tables; therefore, some data is not directly comparable to past CBECs.
