Project
The ECOSLIGHT: Environmental Conscious Smart Lighting project, supported by the European Framework of Erasmus+ / Sector Skills Alliances Programme, aims to enhance employability and improve the career prospects of lighting-related professionals, while also help businesses to find the right competences they need to increase their competitiveness. Project outputs will directly benefit lighting-related professionals (e.g. architectures, engineers, decorators, ICT professionals, etc), as well as market companies, associations and social partners, municipalities and policy makers. Indirectly, the project will contribute to raising the quality of life of the general public, by enabling smart buildings and cities to provide enhanced lighting experiences. Overall, the project is expected to present a serious impact in raising the productivity and results of professionals working in the construction sector, and especially in the areas of exploitation of contemporary technologies, energy saving, and human well-being.
