Abstract
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 F and k W , respectively) are smaller than 1 W/m 2 K. Electric lighting fixtures (7) and heaters (8) which have at least approximately equal power ratings are used for lighting and heating.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
110 words
The combination of a building having at least one room with an outside wall including a window having a heat transfer rate of at most 1 W/m 2 .K and an opaque wall part having a heat transfer rate of at most 1 W/m 2 .K; a plurality of electric lighting fixtures of predetermined power range in said room for providing artificial light; and a plurality of electric heaters in said room for providing heat, said heaters having a power rating of from 50% to 150% of said lighting fixtures, each said heater being coupled with a respective lighting fixture for selective operation of said lighting fixture or said heater.
Claim 2
Dependent Claim
110 words
The combination of a building having at least one room with an outside wall including a window having a heat transfer rate of at most 1 W/m 2 .K and an opaque wall part having a heat transfer rate of at most 1 W/m 2 .K; a plurality of electric lighting fixtures of predetermined power range in said room for providing artificial light; and a plurality of electric heaters in said room for providing heat, said heaters having a power rating of from 50% to 150% of said lighting fixtures, each said heater being coupled with a respective lighting fixture for selective operation of said lighting fixture or said heater.
Claim 3
Dependent Claim
36 words
The combination as set forth in claim 1 which further includes a plurality of radiation reflectors in a ceiling of said room, each reflector having one of said lighting fixtures and one of said heaters therein.
Claim 4
Dependent Claim
27 words
The combination as set forth in claim 1 wherein said lighting fixture and said heaters have a total power consumption of 25 W/m 2 of room surface.
Claim 5
Dependent Claim
35 words
The combination as set forth in claim 1 wherein said window has a heat transfer rate of 0.7W/m 2 K and said opaque wall part has a heat transfer rate of 0.5 W/m 2 K.
Claim 6
Dependent Claim
112 words
The combination of a building having at least one room with an outside wall including a window having a heat transfer rate of at most 1 W/m 2 K and an opaque wall part having a heat transfer rate of at most 1 W/m 2 K; a plurality of electric lighting fixtures in said room for providing artificial light, each said fixture having a predetermined power rating; and a plurality of electric heaters in said room for providing heat, said heaters having power rating of from 50% to 150% of said fixtures with the total power rating of said lighting fixtures and said heaters being equal to 25W/m 2 of room surface
Claim 7
Dependent Claim
112 words
The combination of a building having at least one room with an outside wall including a window having a heat transfer rate of at most 1 W/m 2 K and an opaque wall part having a heat transfer rate of at most 1 W/m 2 K; a plurality of electric lighting fixtures in said room for providing artificial light, each said fixture having a predetermined power rating; and a plurality of electric heaters in said room for providing heat, said heaters having power rating of from 50% to 150% of said fixtures with the total power rating of said lighting fixtures and said heaters being equal to 25W/m 2 of room surface
Claim 8
Dependent Claim
27 words
The combination as set forth in claim 5 wherein the maximum power rating of said heaters does not exceed the maximum power rating of said lighting fixtures.
Claim 9
Dependent Claim
44 words
The combination as set forth in claim 5 which further comprises means for controlling the turn-on of said lighting fixtures and said heaters whereby the emitted total power of said turned-on fixtures and heaters is limited to the value of the installed lighting power.
