−	A building's performance is a measure of how well it functions in relation to designated criteria such as physical, social or environmental considerations. For example, a building's physical efficiency might be evaluated by assessing parameters such as heat loss, energy use, water use, water tightness, structural performance, fire performance and so on. It can also measure whether the resources necessary to design and construct a building have been used effectively.	+	A building's performance (or efficiency) is a measure of how well it functions in relation to designated criteria such as physical, social or environmental considerations.

	Assessments can be made for all building types and are particularly important in housing. Concerns about how buildings perform date back at least as far as Neolithic times. Cave dwellers would assess their habitat against criteria such as; shelter from the elements, safety against animal attack, conspicuity, and solar orientation. Similar concerns have preoccupied people ever since, but the list has grown with increasing construction complexity and tighter regulatory requirements.
