A sealing element for sealing joints and the intermediate space between an inner wall, an outer wall shell and a window frame includes (1) a first block-shaped sealing element section of a first flexible foam having a first indentation hardness and (2) a second web-shaped sealing element section which projects from an edge area of the first sealing element section, the second sealing element section including at least one sealing strip which is a second flexible foam having a second indentation hardness, the first indentation hardness being at least 1.5 times greater than the second indentation hardness.

An airloop window wall system with solar energy units integrated into the window wall panels is disclosed. The disclosed system provides electrical connections between adjacent solar energy window wall panels without compromising the window wall watertightness performance and permits easy replacement of solar energy units from the building interior.

A docking system between a vehicle and a building and a control method therefor include an entrance frame configured to extend in a direction towards a vehicle door, an external door provided at a side of the vehicle door to be opened, an internal door spaced from the external door and provided at a side of the building to be opened, and a sealing unit inserted into the entrance frame to be provided between the external door and the internal door, and configured to selectively extend in the direction toward the vehicle door to connect an internal space of the vehicle and an indoor space of the building into one space.

In a one aspect there is disclosed a formwork wall panel (10) having an operative inner surface (12) to face towards an inner space to be filed with building material and an opposing operative outer surface (14) having a surface finishing component (16) secured thereto. The operative inner surface (12) of the formwork wall panel (10) includes a brace coupling formation (18) operatively adapted to engage a wall panel coupling formation (20) of a brace (22) operatively extending between the formwork wall panel (10) and an opposing second formwork wall panel.
