Human perceptions and emotions are influenced by the environment around us. This reflects the light and our senses get information.
We shouldn't restrict ourselves to feel and interpret what we just see. The essence of things stays within the relationship between those things and reality. Light is the means, therefore, changing light will change the information we get from reality.
The role of the designer should be using light to bring spaces to life. Through architecture and urban knowledge, the designer should be able to turn spaces into places, where people find their own identity. Both increasing the feelings of safety and well-being and inviting people to be curious in discovering new spaces and emotions - reducing distances (physical and visual) between them and the information entities - the places planned will assume a human scale dimension.
The knowledge in interpreting sites and spaces should give the designer the possibility to propose environment enriched with their real essence, with their physical and symbolic features. So creating emotions and sensations.
Often we are surprised by the way the sunlight - through a specific angle, with a particular effect on an object or with a certain colour temperature - gives us emotions, sensations and physical and psychological wellbeing. So why shouldn't we try to reach the same feelings level - start thinking about spaces, architectures, objects and light as all part of the built environment?
With those tools we are then able to design squares, streets, buildings and objects. So we can then steer or satisfy human behavior and needs together with the capability to enhance different types of human activities.
Anyway we shouldn't forget that thanks to the "filter" called LIGHT we can really focus on the main actors we design, think and study the built environment for:
