Abstract
Abstract For lowering the energy requirement for a room (2) ventilated by a ventilating system (11 to 17) of a building (1), windows (4) and opaque wall parts of the outside wall (3) are designed so that the heat transfer numbers (kF and kW, respectively) are smaller than 1 W/m 2 .K. In addition, the supply air flows into the room (2) near the floor (9) at the comfort temperature of at most 20° to 22° C. and an input velocity which does not exceed a maximum air velocity which is permissible for comfort conditions in an occupied zone.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
101 words
The combination of a building having at least one room with a floor and an outside wall including a window having a heat transfer number of at most 1 W/m 2 K and an opaque wall part having a heat transfer number of at most 1 W/m 2 K; and a ventilating system for feeding air into said room over a width of at least one wall of said room and adjacent said floor, said ventilating system including a blower for blowing the air into said room at a velocity below a predetermined comfort velocity for an occupant in said room.
Claim 2
Dependent Claim
101 words
The combination of a building having at least one room with a floor and an outside wall including a window having a heat transfer number of at most 1 W/m 2 K and an opaque wall part having a heat transfer number of at most 1 W/m 2 K; and a ventilating system for feeding air into said room over a width of at least one wall of said room and adjacent said floor, said ventilating system including a blower for blowing the air into said room at a velocity below a predetermined comfort velocity for an occupant in said room.
Claim 3
Dependent Claim
25 words
The combination as set forth in claim 1 wherein said blower blows air into said room at a maximum velocity of 0.2 meters per second.
Claim 4
Dependent Claim
43 words
The combination as set forth in claim 1 wherein said ventilating system includes an exhaust air opening adjacent a ceiling of said room for exhausting air from said room, said opening extending over at least 80% of the width of said outside wall.
Claim 5
Dependent Claim
48 words
The combination as set forth in claim 1 wherein said ventilating system includes a grille adjacent to said floor for blowing a supply of air from said blower across said floor and an exhaust air opening adjacent a ceiling of said room for exhausting air from said room.
Claim 6
Dependent Claim
41 words
The combination as set forth in claim 4 wherein said ventilating system includes a heat exchanger for receiving and exchanging heat between a flow of exhaust air from said exhaust air opening and a flow of supply air to said grille.
Claim 7
Dependent Claim
38 words
The combination as set forth in claim 5 wherein said ventilating system includes a heater for heating the flow of supply air to said grille to a comfort temperature of at most from 20° C. to 22° C.
Claim 8
Dependent Claim
24 words
The combination as set forth in claim 1 which further comprises at least one electric lighting fixture in said room for providing artificial light.
Claim 9
Dependent Claim
83 words
The combination of a building having at least one room with a floor and an outside wall including a window having a heat transfer number of at most 1 W/m 2 K and an opaque wall part having a heat transfer number of at most 1 W/m 2 K; and a ventilating system for feeding air into said room at a maximum velocity of 0.2 meters per second over a width of at least one wall of said room and adjacent said floor.
Claim 10
Dependent Claim
83 words
The combination of a building having at least one room with a floor and an outside wall including a window having a heat transfer number of at most 1 W/m 2 K and an opaque wall part having a heat transfer number of at most 1 W/m 2 K; and a ventilating system for feeding air into said room at a maximum velocity of 0.2 meters per second over a width of at least one wall of said room and adjacent said floor.
Claim 11
Dependent Claim
50 words
The combination as set forth in claim 8 wherein said ventilating system includes a grille adjacent said floor, a blower for blowing a supply of air through said grille and across said floor and an exhaust air opening adjacent a ceiling of said room for exhausting air from said room.
Claim 12
Dependent Claim
41 words
The combination as set forth in claim 9 wherein said ventilating system includes a heat exchanger for receiving and exchanging heat between a flow of exhaust air from said exhaust air opening and a flow of supply air to said grille.
