A platform for research: civil engineering, architecture and urbanism
Problem of lighting economy claimed to be considered for first time in its broader aspects, taking account of both artificial lighting and daylighting, and their relation to one another; proposed procedure is to base lighting considerations on two main factors, "external light intensity" and "daylight ratio"; costs of artificial lighting and daylight illumination. English abstract from Kraft och Ljus v 24 n 1 Jan 1951 p 1-7. (British Edition)
