- Abstract
- To substantiate an extensive use of daylight in commercial buildings it is necessary to demonstrate that, other than just providing potential energy savings, natural lighting can foster further benefits (financial, environmental and in terms of productivity) for both the owners and the occupants. Specifying daylighting solutions for energy efficiency can be a very complex task, where many factors (e.g. illuminance, glare, solar gains, views) can diverge from each other making design choices extremely difficult. Nonetheless, to foster the design of energy-conscious buildings which are also conducive to human well-being, these variables have to be related with qualitative and behavioural factors such as time/duration of exposure, directionality and spectral composition of visible radiation, psychological stimulation and user preference. Correlating literature research with lighting standards and field measurements, this paper looks at the relationship between quantitative physical factors of the luminous environment (e.g. horizontal/vertical illuminance,luminance ratio, colour temperature), qualitative aspects of vision (e.g. uniformity, distribution, contrast) and physiopsychological human response to daylighting. The aim of the study consists in defining a framework to implement existing recommendations based not only on photopic requirements for visual tasks but also containing awareness of the demands for photobiological stimulation that can influence the well-being of occupants, whilst also enhancing energy savings
