This paper illustrates that frail older people, demand other requirements to the Indoor Environment where they reside when compared to those general being used in guidelines for older people residents We propose an approach using the International Classification of Functioning and Disabilities (ICF) from the World Health Organization (WHO) as a framework for the relations of environmental factors on one hand and daily activities and participation of frail old people on the other hand. To examine these relations in the environments where older people reside, Evidence Based Design (EBD) is used for the theoretical concept for healing environments. This concept is formed from practices based or experimental based research in building design with a positive health outcome. In case of frail older people we cannot speak of a healing environment. Frail people at age will not heal from the restrictions they experience due to the biological ageing. We can create though enriched environments for them, healthy environments which support their well-being and where their health doesn’t further decline. Healthy environments consist of environments with an indoor environmental quality (IEQ) which fits with the baic functions of the users. This approach illustrates that older frail people and their carers put other demands to their environments which are beyond shelter, safety and security. The outcomes of the approach show that: Creating enriched environments demands a) knowing the needs and values of frail people and their caregivers and b) understanding the effect of the physical environment on people functioning and well-being. Capturing these needs can be done through use of several sources from literature till participatory workshops with (representative of) the frail older adults and their caregivers. It is also necessary to involve staff and management. In addition, values and needs are translated via interdisciplinary knowledge of gerontechnology building design and healthcare to functions of the users in the environment while taking into account the restrictions due to their health condition
