Building, notably a residential building or one receiving the public, the outer envelope of which comprises at least one facade portion, preferentially an entire facade, which delimits an outside and an inside, which is transparent to the solar radiation, substantially over its entire surface, and which is situated on a face of said building oriented on the south side when said building is located in the northern hemisphere and, conversely oriented on the north side of said building when the latter is located in the southern hemisphere, the form of at least a part (3, 3') of said at least one facade portion being inscribed substantially within the conical surface generated by an imaginary segment extending between the Sun and a corresponding point which is fixed with respect to the Earth, upon a complete rotation of the Earth on itself, said or each facade portion extending between a base line and a top line or edge which delimit it with respect to the remaining part (1") of the outer envelope of the building, this remaining part (1") being mostly or totally opaque, building characterized in that the outer face of said or each abovementioned part (3, 3') of facade portion or facade is inscribed approximately within the surface of a part of a frustum, forming part of the conical surface generated by the abovementioned imaginary segment, which is situated under the horizontal plane containing the associated fixed point and of which the imaginary top is said fixed point, which is situated above the top edge of the part (3, 3') of facade portion concerned, in that the outer face of each abovementioned part (3, 3') of the facade portion is, at each point of the top edge, situated set back and inclined inward with respect to a straight line perpendicular to the local horizontal plane, that is to say a straight line normally perpendicular to the plane of the ground, and passing through this point of the top edge, and in that at least one of the abovementioned facade parts (3, 3') forming the facade portion is inscribed within the surface of an abovementioned frustum part which is recessed or concave with respect to the face considered seen from the outside. said or each facade portion extending between a base line and a top line or edge which delimit it with respect to the remaining part (1") of the outer envelope of the building, this remaining part (1") being mostly or totally opaque, building characterized in that the outer face of said or each abovementioned part (3, 3') of facade portion or facade is inscribed approximately within the surface of a part of a frustum, forming part of the conical surface generated by the abovementioned imaginary segment, which is situated under the horizontal plane containing the associated fixed point and of which the imaginary top is said fixed point, which is situated above the top edge of the part (3, 3') of facade portion concerned, in that the outer face of each abovementioned part (3, 3') of the facade portion is, at each point of the top edge, situated set back and inclined inward with respect to a straight line perpendicular to the local horizontal plane, that is to say a straight line normally perpendicular to the plane of the ground, and passing through this point of the top edge, and in that at least one of the abovementioned facade parts (3, 3') forming the facade portion is inscribed within the surface of an abovementioned frustum part which is recessed or concave with respect to the face considered seen from the outside.
