Although solid state lighting is considered the dominant lighting technology for the future there exist no concrete methods to evaluate LED luminaires and decide the optimal one for each lighting application. Multicriteria decision methods are utilized in various decision problems so as to evaluate alternatives through complex and conficting criteria. This paper introduces a decision support system for a complete techno-economic evaluation of LED luminaires through multicriteria analysis. Seven criteria are proposed so as to assess the technical and economic characteristics of LED luminaires and ensure their compliance with European Norms regarding ofce lighting. Laboratory measure- ments and lighting calculations in 8 indoor types of LED luminaires are performed so as to defne their technical characteristics and evaluate their performance con- cerning the lighting of an ofce. Finally, the PROMETHEE II multicriteria method is applied, which ranks the 8 types of luminaires and determines the optimal one. The proposed decision support system can be applied to any type of luminaire and can be used by professionals who want to evaluate diferent luminaire suppliers and determine the optimal luminaire tender for the lighting of any indoor space.
