FEASIBILITY STUDY OF MODERN ENERGY EFFICIENT LIGHTING SYSTEMS OF APARTMENT BUILDINGS

Abstract

The article describes the possible priority actions of electricity efficient usage for staircases and technical rooms lighting in apartment buildings. The advantages and disadvantages of the main energy-saving lighting products available on the market of electrical products in Ukraine are marked. For different types of combined systems «ighting devise-switch» the cost-benefit analysis in aggregated indexes is compared. It is shown that only the replacement of a simple switch on the optical-acoustic circuit breaker or switch with an infrared motion sensor (PIR sensor) will save on lighting worth about 290 UAH per year, in comparison with a conventional incandescent lamp of 40 W. The achieved economic effect allows recoup the cost of this type of combined «ighting devise-switch» system within 6—13 months, depending on the electricity tariff and the work duration in the dark.
