I also take great satisfaction in positive comments from building owners - and from residents who appreciate living in a properly lit place. Of course, the lighting has to function as it's supposed to and fulfill its primary function of effective illumination. But you also have to touch people emotionally, excite their sensibility. Lighting choices and techniques must contribute to the quality of living and well-being.
Finally, it's important to do lighting which has an effect on the immediate environment, which escalates the whole area and makes it vibrant, lively, exciting - when before it was troubled and neglected – and to contribute to the economic development of a once unpopular neighborhood thanks to appropriate lighting.
