Daylight has potential to stimulate individual’s sensations and feelings. Older people who live in care homes have sense of daylight that might influence them psychologically. The psychological effects of daylight can be observed under two incidents: longer-term effects and short-term effects. The longer term effects of seasonal change of light on individual’s behaviour and mood, i.e. SAD is one of the most developed researched subjects among the psychological effects of natural light. Similarly, as short term effects, illuminance and correlated colour temperature (CCT) of light create stimulation to individuals’ sensations that might affect individuals’ moods.

Light can impact on wellbeing: physically, physiologically, and psychologically. Still, the short-term effects of light (i.e. impact of light on mood and behaviour at a particular moment) are a matter of dispute within the scientific research community. At an empirical level, the existing literature contains a mix of contradictory evidence of short term effects of light on individuals’ moods. The short-term effects of varying levels of indoor/outdoor illuminance, on individuals’ moods are largely unknown. This research investigated, in addition to the established long term effects of light on individual’s mood and behaviour (i.e. SAD), if there is any short term effect of natural illuminance on individual’s mood.

MSV2 aimed to develop a decision support system using modelling and simulation to optimise lighting design of healthcare spaces. The main objectives were to:
• explore and develop new theory relating to the association between outdoor ambient illuminance and elderly’s moods in a care home;
• develop a knowledge base on the impact of lighting in therapeutic performance, safe navigation and clinical outcomes of patients;
• investigate the application of building simulation tools in design practice; and
• investigate the role of advanced computer opitmisation techniques in healthcare lighting design.
