More than any building material, light produces spatial effects, generates moods, and "stages" architectural designs. In well-lit spaces, we feel good, and we are capable and effective; light promotes health. Moreover, especially in office buildings, the combination of a sensible natural lighting design with a corresponding approach to artificial lighting is a decisive factor in energy conservation. Assembled by experienced authors and experts from the worlds of practice and teaching, this new volume in the series Detail Praxis provides an introduction to the most important aspects of natural and artificial lighting design. In addition to straightforward planning rules - such as ground plan design, building orientation, and the structuring of facades - it also introduces and explains current natural and artificial lighting systems with the help of example projects.
