In the late 1960s an emerging trend toward buildings admitting little or no daylight were constructed which had a dramatic effect on mental alertness, productivity and psychological well being.6 In 1965 the “congress of occupational medicine stated that humans do not need natural lighting in work environments” (p1)17 A series of studies were conducted by the Herschong Mahone Group between 1999 and 2003 examining the effect of natural light on telephone call centre workers, school students and retail shoppers with findings of increased productivity, performance and sales correlated with the introduction of daylight.18, Crone suggests that many architects overlook, do not appropriately understand and under utilise natural lighting, particularly the dynamic nature of daylight and its variability in different seasons and countries.19 It is only in the last two decades that this is becoming easier with the availability of more complex computer modelling.19 In 1991 Kendrick argued that the variability of daylight should be recognised and considered in design beyond the base level overcast grey skies of Great Britain and Northern Europe.20, Windows and lighting have been considered in varying ways in the history of buildings design, with consideration of environmental and cost saving issues.
