A multidimensional assessment of efficient lighting technologies in the industrial sector

Addressing the impacts of energy efficient lighting systems in the industrial sector from a multidimensional perspective requires the formulation of a proper modelling framework. Input-Output (IO) models can be particularly suitable, since they can be adjusted to embed economic, social and environmental impacts that can be consistent with different energy policy recommendations. This paper is aimed at presenting an IO modelling framework which allows for the appraisal of economic, energy and environmental (E3) impacts of several energy efficient lighting systems in the Portuguese industrial sector, grasping their trade-offs by means of a multiobjective integer programming (MOIP) problem.
