With the rapid population ageing in Europe and in Denmark, there is an increasing interest in technologies and designs that can support the elderly citizens in sustaining well-being and health along with preventing functional decline [1]. To date, the designs of lighting systems in elderly housing are simple and primarily made to support only visual acuity without taking into account other parameters [2]. But elderly people have higher demands on quality of light as their body has to cope with immobility, pathologies and age-related functional decline [3]. In this context, this paper investigates the development of a personalised and adaptive intelligent system [4] to adjust the lighting design in order to improve well-being and comfort levels, as well as to meet the needs of elderly people at home. To this goal, circadian adjusted LED-based (CaLED) lighting is used, which can reflect the rhythm of out-door daylight. CaLED lighting seems that may positively influence age-related needs, mood, cognition, alertness, sleep and improve well-being in general [5][6]. To build this intelligent system 3 different types of data are considered and cross-checked: a) medical (biofactors), b) sensor-based (activity detection, actigraphy, etc.) and c) anthropological (mood and behaviour). This way, the effect of circadian lighting on well-being, can be also documented, before this new technology can be recommended for implementation in elderly housing. A test installation is planned at “Sundhedshuset” in Albertslund, Denmark: 15 flats with frail elderly and 9 flats with people with dementia are used. [1] Lynch, J., & Draper, H. (2014).
