A multi-criteria decision making approach in lighting technology selection for a production hall

Nowadays, lighting industry can contribute to a more sustainable future, by reducing the total consumption of electrical energy used to illuminate indoor and outdoor spaces. Thus, lighting system design is one of the important components when thinking about building sustainability. Taking into account the final purpose of the lighting installation (the type of human activity that will take place in the indoor space for which lighting is to be provided), the most suitable lighting technologies are selected considering their characteristics, dimensions, and technical specification. The paper presents how a lighting technology selection for a production hall using a multi-criteria decision making approach. There are considered the most common luminaires and lamps which can assure the illuminance necessary for the hall, which represent the variants, evaluated against several criteria, considering the decision maker’s preferences and constraints. The variants are ranked according to their performance for each criterion. The optimal lighting solution obtained after the simulation experiment suggests that ELECTRE III method is a practical decision-making model that can be considered for this type of decisions

A multi-criteria decision making approach for public lighting system selection

There are numerous and different ways to design an energy efficient street lighting system, but not always the best technical solution is the optimal economic solution as well. In this paper, we used two distinct software tools in order to obtain the optimal technical and economic solution for selecting street lighting technology. The first software used was DIALux, which is frequently applied in this field, assisting designers in choosing the most appropriate electrical installations and evaluating the technical performance of the chosen solutions. This tool determined the street lighting system variants for which there are predetermined configurations, so that the lighting parameters obtained are in accordance with the normative requirements of the lighting classes in which the roadways are included. Different ways of locating the luminaires and other parameters were changed to reach the best version that meets the qualitative requirements of the lighting technology. The second software used was the one developed by the authors, based on ELECTRE III method, which evaluated the technical solutions returned by DIALux against several criteria, taking into account the designer’s preferences and constraints. The optimal technical and economic solution was obtained after ranking the variants by their performance at each criterion. The simulation experiment and the results returned suggested that the combination of the two software tools is comprehensive and effective and it can be used in this type of decisions at large scale
