Abstract
For reducing the energy required for lighting and heating in a room (2) of a building (1), windows (4) and opaque wall parts (3) of the outside wall are designed so that their heat transfer numbers (k.sub.F and k.sub.W, respectively) are smaller than 1 W/m.sup.2 K. Electric lighting fixtures (7) and heaters (8) which have at least approximately equal power ratings are used for lighting and heating.
