ENERGY-EFFECTIVE TECHNOLOGIES FOR HOUSING AND UTILITIES USING A CASE STUDY OF ENERGY SAVING ILLUMINATION IN ENTRANCE HALLS OF APARTMENT BUILDINGS

1A real life case study of energy saving in housing and utilities is presented. The potential of using auto controlled illumination systems for entrance halls of multistory apartment buildings is analysed. This system identiﬁed movement in an entrance hall and depends on external illumination. Energy efﬁciency of this system, its ﬁnancial beneﬁts and payback period are estimated. An economic evaluation of an autonomous system for entrance hall illumination using photo-electric batteries is given.
