Abstract
In order to minimize energy consumption for lighting and increasing lighting quality in existing offices old lighting systems can be retrofitted with more efficient luminaires. Additional savings can be achieved by installing a lighting control system. Installation time and costs can be reduced by installing LED luminaires equipped with inbuilt lighting controls. In the case study six rooms were analysed: in two rooms the old lighting system has been retrofitted with LED luminaires with inbuilt active dimming controls; in two rooms LED luminaires without dimming were installed and two rooms were left as reference. Old and new lighting systems performances were measured in terms of energy efficiency, lighting quality and user satisfaction. The conducted analysis can be used as a monitoring guideline for the evaluation of lighting retrofitting results.Description
