ByA. Tsangrassoulis

INTRODUCTION After the 1970s energy crisis, interest in daylighting – among other solar applications – began to be re-examined in an effort to reduce energy consumption. Today, with the advancing problem of global warming, daylighting is considered a very important strategy to ‘replace’ the electric energy demanded by artificial lighting, reducing not only lighting (and cooling) consumption, but efficiently decreasing peak electrical loads.
