Surveying is often the simplest and least-expensive method for evaluating IEQ concerns in a building [24]. Occupant satisfaction is ultimately the primary interest of the building owner/operator regardless of physical IEQ conditions. There are many survey tools available for studying IEQ satisfaction among occupants. Schiavon and Peretti’s review of IEQ surveys [28] provides a historical account of IEQ surveys. The two most widely used survey methods are the Building Use Studies Ltd. (BUS) [29] and the Center for the Built Environment (CBE) survey [30].
