the channels are vertically extending and concentric, the internal channel extending the height of the well and the external channel extending only over the upper portion of the well; and a cap, adjustable in height, at a top of the ventilation well. ### Claim 2 (depends on 1) The combination according to claim 1, wherein the cap has a shape of a truncated cone, cone, truncated pyramid or pyramid. ### Claim 3 (depends on 1) The combination according to claim 1, wherein the cap is made from wood, metal, glass, composite materials or a combination thereof. ### Claim 4 (depends on 1) The combination according to claim 1, wherein the well is made of metal, composite materials, fibre-reinforced concrete or a combination thereof. ### Claim 5 (depends on 1) The combination according to claim 1, wherein the ventilation well comprises foundation elements that extend around a base of the well. ### Claim 6 (depends on 1) The combination according to claim 1, wherein the well comprises network elements required for the building. ### Claim 7 (depends on 1) A kit comprising prefabricated elements for assembly of the ventilation well according to claim 1. ### Claim 8 (depends on 1) The combination according to claim 1, wherein the cap is removable. ### Claim 9 (depends on 1) The combination according to claim 1, wherein the cap is made from a material in the form of panels on a metal frame. ### Claim 10 A ventilation well for use with a building having a roof for providing hurricane resistance, the well comprising: a vertically extending central element having an outer wall, a height, a top portion and a bottom portion; an internal channel having at least one lower lateral opening located in the bottom portion of the central element and an internal top opening located at a top of the well for communicating with an exterior of the building at the roof, and an external channel having at least one upper lateral opening located in the top portion of the central element and an external top opening located at the top of the well for communication with the exterior of the building at the roof, each lateral opening extending through the outer wall of the central element for communication with an internal volume of the building; the channels are each vertically extending and concentric, the internal channel extending the height of the central element and the external channel extending only along the top portion of the central element; and a removable cap at the top of the ventilation well. ### Claim 11 (depends on 10) The ventilation well according to claim 10, wherein the cap has a shape of a truncated cone, cone, truncated pyramid or pyramid. ### Claim 12 (depends on 10) The ventilation well according to claim 10, wherein the cap is made from wood, metal, glass, composite materials or a combination thereof. ### Claim 13 (depends on 10) The ventilation well according to claim 10, wherein the cap is made from a material in the form of panels on a metal frame. ### Claim 14 (depends on 10) The ventilation well according to claim 10, wherein the well is made of metal, composite materials, fibre-reinforced concrete or a combination thereof. ### Claim 15 (depends on 10) The ventilation well according to claim 10, wherein the ventilation well comprises foundation elements that extend around a base of the well. ### Claim 16 (depends on 10) The ventilation well according to claim 10, wherein the well comprises network elements required for a building. ### Claim 17 (depends on 10) A building comprising at least one ventilation well according to claim 10.
