A roof system that includes a roof covering in the form of planting areas, a water storage, a wind turbine, a water turbine, a solar panel, and a water heater. The roof system includes a plurality of ceramic chambers each including a wind turbine and a recess for housing a planter area.

A green roofing substrate brick comprises a water-permeable fabric box having an open top, and a solidified and non-compressed substrate in the box. The substrate comprises a water storage and drainage medium, and a binder solidifying the water storage and drainage medium.

The present disclosure relates to a precast load bearing roof deck element for a building comprising an upper floor layer of concrete, a load bearing steel reinforced lower layer of concrete, at least one thermally insulating layer located between and separating the upper floor layer of concrete and the lower layer of concrete, and a plurality of binders extending between the lower layer of concrete and the upper floor layer of concrete, the roof deck element configured to be mounted on a load bearing construction of the building. The disclosure also relates to a roof construction comprising a load bearing construction, such as a column and beam construction, and at least two of the above mentioned precast load bearing roof deck elements, wherein the roof deck elements are positioned side by side forming a gap between the roof deck elements, wherein the distance between the roof elements is between 0 mm and 100 mm, or between 1 mm and 100 mm. Furthermore the present disclosure relates to a method for manufacturing a load bearing roof deck element and a method for installing a roof construction on a load bearing construction of a building.

Insulation element for thermal and/or acoustic insulation of a flat roof, comprising a first layer made of mineral wool and a second layer made of at least one fabric, whereby the second layer is fixed to a major surface of the first layer by an adhesive, whereby the first layer is made of at least one lamella having a fiber orientation predominantly perpendicular to major surfaces of the second layer, whereby the first layer contains a cured binder whereby the adhesive is arranged partly in an area between fibers close to the major surface of the first layer directed to the second layer and in an area close to the major surface of the second layer directed to the first layer so that the adhesive connects the first layer and the second layer in such a way that forces directed perpendicular to the second layer can be compensated by the tensile strength of the second layer in combination with the adhesive and/or the deflection of the fibers of the first layer causing a maximum deformation of ≤5% of the thickness of the first and second layer.

The present application relates to the technical field of architectural engineering. Disclosed are a slab joint leakage-proof structure of a prefabricated roof panel, a prefabricated roof panel and a prefabricated roof panel system. The slab joint leakage-proof structure comprises a first leakage-proof layer. The first leakage-proof layer comprises two flexible structures which abut against each other and are arranged at the joint of a main rib on the long side of the roof panel and a main rib on the long side of an adjacent roof panel. Either of the flexible structures comprises a main body portion sealably attached to the main rib, and at least one protruding portion which is fixedly disposed on the main body portion, protrudes and extends into the joint, and can tightly abut against the other flexible structure. The protruding portions of the two flexible structures can enclose an air cavity layer sealably isolated from the outside. The air pressure of the air cavity layer is higher than that of the outside for preventing liquid on the bottom end of the joint from permeating into the air cavity layer and entering a room. The slab joint leakage-proof structure has good waterproof performance. The flexible structures are sealably connected to the main ribs, and are not easy to fall off, and the problem that the waterproof performance is poor due to the fact that a mortar is easy to fall off in an existing waterproof mode of filling the mortar is solved.

Certain exemplary embodiments can provide a system, machine, device, and/or manufacture that is configured to operably manage a flow of storm water that enters a drainage system of a roof and comprises one or more of a retention layer configured to retain storm water, a friction layer configured to delay a peak flow of the storm water into the drainage system, and a detention layer.

Embodiments provide a greening module, a greening device, a greening body and a method for installing the greening module. In the embodiments, the greening device includes at least one greening module including plants, a plant culture layer, an adhering part, and a waterproof layer, wherein: one side of the plant culture layer is configured for cultivating the plants, and at least part of a surface of an other side is provided with the adhering part; the waterproof layer is provided between the plant culture layer and the adhering part.
