In addition to the health and wellbeing value of Human Centric Lighting SSL can enhance productivity and enable green business development and green jobs.
SSL investments enable higher value of light and numerous operational advantages. This means that it can make our living and working environments more attractive, i.e. more valuable for the users and owners. At the same time SSL facilitate energy savings. This means that that SSL supports multifaceted improvements of the LCA quotient between total functional value and total environmental load:
It is very difficult to calculate a single reasonably accurate number for this quotient. The main value of the above ratio is as a conceptual tool for comparison of different lighting system alternatives. The amount of electricity is environmentally important, but it is not the only resource and environmental load consideration.
The value of light is influenced by more parameters than the lumen value. The interoperationability is important for development of smart cities and smart buildings and the build up of renewal-oriented capability is important for ability to make proper use of new technologies.
