Motivation Keeping up with changes Society is undergoing rapid demographic change. The number of elderly people is set to rise inexorably. This means that in future there will be more and more people who require care. Long-term care is therefore facing new challenges in terms of both quantity and quality. The challenge is to cater for the special needs of all care home residents. Illnesses such as dementia and Alzheimer’s, restricted mobility and impaired vision are among the factors that make demands on care personnel. The right lighting for greater quality of life Eyesight usually...

Requirements Vision and feelings Eyesight begins to gradually deteriorate from the age of around 40. Most people need reading glasses to read fluently from this age onwards. The lens of the eye gradually becomes less transparent and most people realise, for the first time, that they need more light in order to see properly. Older people need more light. For a given visual task, they require almost four times as much light as younger people do. These facts have an impact on responsible lighting design for care homes, especially in corridors and meeting areas. Old age brings new challenges...

Study results St. Katharina residential care home, Vienna Light provides important timing cues for our body. The circadian system physically and psychologically controls our sleep-wake rhythm over the course of a day. The production of important metabolites drops off as we age: melatonin and serotonin are responsible for keeping our inner clock ticking over. This poses the question of whether it is possible to use light to stabilise the circadian rhythms of persons who need care, thereby improving their quality of life. Question Does a higher, dynamically controlled light input result in...

Study design As part of the study, a standard situation and its impact was compared to lighting situations where lighting intensities and colour temperatures varied or mimicked dynamic daylight transitions. The behaviour of residents was observed and analysed over an extended period of time. Particular interest was paid to communication and interaction between residents and with nursing staff. Data was collected for a total of 15 residents who had an average age of 88 years over the observation period. They were primarily women who had received vocational training. All the residents...

Findings The trial was very revealing and produced positive results in the case of dynamic lighting: • Residents became more active • Residents spent more time in day rooms • Communication with care staff intensified • Sleeping patterns improved • Working conditions for care staff became more pleasant The luminous ceiling in the St. Katharina residential care home was able to compensate for a lack of daylight. Dynamic lighting scenarios in which colour temperature and lighting intensity were varied over the course of the day produced especially good results. During the day, high luminance...

Standard and recommendations Excerpts from various guidelines Standard EN 12464 does not make sufficient allowance for the marked deterioration in visual function that affects the elderly, or their resulting needs. For instance, this standard contains very precise specifications for lighting in office buildings and applicable requirements but more exacting requirements due to the elderly’s poor vision occupy a subordinate role. VDI Guideline 6008¹ on lighting in hospitals, nursing homes and intergenerational dwellings and the Guide² to daylight-oriented interior lighting of homes for the...

Lighting for communal spaces Being together and being active The day room is the heart of any care facility. It is the central point for meeting, communicating, being active and lounging. Value can be added to the time that residents spend here. They discuss, read, write, watch TV, do needlework or eat, communally. The large number of activities performed here and their disparate nature make heavy demands on lighting. Functional and visual requirements must be met equally effectively and the need for a cosy, homely feel must also be met. Light has the ability to stimulate elderly residents...

Balanced lighting solutions for communal spaces In care settings, the focus of attention is on the individual; lighting design also focuses on the individual. Higher lighting levels, variable colour temperatures and changes from diffuse to directional light distribution help stabilise natural sleep-wake rhythms. The higher energy consumption this involves is easily justified by the improved lighting quality obtained and associated feel-good factors. LENI energy efficiency Basic Lighting quality – Uniform general lighting with gentle light distribution that also brightens up walls and...
