Architectural Lighting Development when Financial Restrictions Apply

The paper is dedicated to economic analysis of the possible design decisions for the architectural lighting of the building of the Faculty of Electrical Engineering of the TU of Sofia. Such an analysis is necessary because of the financial limitations set for the design and installation costs of the lighting system. Because of the great variety of LED products available on the market today replacement of lighting equipment is possible with minor change of the artistic idea, but with great difference in the amount of the initial investment.
