The „LebensPhasenHaus“ constructed in Tübingen‘s Rosenau district is a building designed to serve the purposes of research and demonstration: It allows the use of both technical assistance systems and associated services to be tested, validated and demonstrated as well as experienced hands-on. The aim of the project is to examine how technical and social innovations can enable the elderly and those in need of care to live for longer in their own homes. Given responsibility for providing energy-efficient LED lighting the house, RIDI mounted light fittings with lighting control systems (with facility for regulation from cold to warm white) in the living room, bathroom and kitchen. These can be controlled for optimum adjustment to the living patterns of the occupants with colour temperatures of between 3000 and 6500 Kelvin.
