People often think that a lighting designer is a specialist in artificial lighting, the kind of lighting that we can switch on and off, the kind of lighting that “colors” the space at night.

This is of course only half of the story as good artificial lighting begins always with an understanding of the natural daylighting involved in the lighting of a space. Firstly, one of the targets of any client or designer must be to reduce the amount of artificial light required to fulfill the task of lighting a space when the natural light disappears as evening approaches. But before we lose ourselves in discussions about the exceptions to the rule, as there may always be exceptions, discos, clubs, the inside of a pyramid, to name just a few of the more obvious, let us say that the better the daylighting concept, beginning with the orientation of the building and the positioning and quality of the openings in the building envelope, the better the artificial light concept will be. The truth is that optimally the artificial and the natural lighting design should be developed parallel, and where possible by the one and the same designer, as they should support each other in their common task of giving the space the appropriate light required for its use. The artificial lighting concept should not be conceived to make up for bad daylight. In general architecture and its interaction with the user will take base on a Day and night basis. They daylight when cleverly done can be enjoyed for free, heat and shading control apart, the space can be lit from above, simply and beautifully with minimum cost. The art of designing the positioning and size of the openings in the building envelope is the task. The lighting architect can influence the orientation of the building in relationship to site, neighboring buildings, north and south east and west. He or she should advise on the shape and materials of the volumes in question. The artificial light builds off this concept and extends the possibilities of use into the darkness of night.

The daylight is the key to good artificial lighting.
