In addition, cooling systems frequently over-cool, delivering temperatures in the summer that are below those in the winter.	+	There is a tendency to create uniform conditions in buildings with a temperature range of between 22 and 24°C, delivered through fully-controlled heating, ventilation and air conditioning (HVAC) systems. However, this is energy intensive and can result in thermal monotony, or thermal boredom. In addition, cooling systems frequently over-cool, delivering temperatures in the summer that are below those in the winter.

	Studies have suggested that for every 1°C of expansion in either direction of the narrowly-controlled thermal ‘dead zone’ annual central HVAC energy consumption can be reduced by 10%. In addition, It is proposed that greater comfort, and even thermal pleasure, can be achieved by a more dynamic, non-uniform environment, and that a temperature range of 21 to 27°C can achieve optimal operative performance.
