The present invention includes a material and method of installing a construction material for dry or arid climates, comprising: a growth media comprising an abiotic porous material and activated charcoal such as biochar; and at least one of a compost, grain hulls and nut shells, wherein plants in the material are able to survive without exogenous water for use in areas comprising at least one of Aw, BS, BW, Csa, Csb, Ds or Dw climates according to the Koppen-Geiger climate classification.

A protected membrane roof system for installation on a roof decking comprising an upper insulation board having an upwardly-facing upper board top surface and an opposite downwardly-facing upper board bottom surface and at least one through-hole communicating therebetween, a ballast material positioned over the upper insulation board, and at least one fastener assembly having a base seated substantially adjacent the upper board bottom surface, a rod extending substantially vertically from the base of sufficient size so as to extend through the through-hole of the upper insulation board and the ballast material, and a cap engaged with the rod above the ballast material, whereby the wind uplift resistance of the protected membrane roof system is improved and scour of the ballast material is reduced by effectively anchoring the ballast material to the upper insulation board beneath the ballast material.

A modular precipitation or rain water retention system having one or more interconnected reservoir retention modules that cooperate to manage effluent from a precipitation event. At least some of the modules are configured to retain an initial amount of rainfall and then meter out the rain water. Each module has one or more frustoconical support structures joined by hollow interconnecting ribs that create a reservoir so that within each reservoir, wells are defined for rainwater retention. At least some of the frustoconical support structures have tops that may underlie a secondary system such as a green layer.

One embodiment provides a modular green roof tray, house plant growth media and horticulture growth media, and a tree protection mat for weed and moisture control made from recycled disposable diapers. The growth medium and tree protection mat contain superabsorbent materials from diaper that can absorb waters and greatly reduce irrigation so to provide a drought resistant feature. One embodiment also provides a manufacturing process to perform 100% recycling of disposed diapers.

The invention refers to a drainage system (100), in particular a roof drainage system, comprising an outlet member (10) and a flow restrictor (20), whereby the flow restrictor (20) is situated above the outlet member (10). The flow restrictor (20) comprises a contact portion (22) and the outlet member (10) comprises a flange portion (12), whereby a first sealing member (30) is arranged on and/or along the flange portion (12) of the outlet member (10) and a second sealing member (40) is arranged at the contact portion (22) of the flow restrictor (20).

A roofing assembly disposed on an underlying support comprising an underlayment assembly disposed in a securing relation to the underlying support. A conduit assembly is disposed on the underlayment assembly and structured to define a path of fluid flow. The path of fluid flow extends along at least a majority portion of said underlayment assembly. The conduit assembly is disposed in a single, continuous, looped relation to the underlayment assembly. A plurality of pan tiles are partially disposed in a confronting relation to the underlayment assembly. At least some of the plurality of pan tiles are partially disposed in an overlying relation to at least a portion of the conduit assembly. The plurality of pan tiles are disposed to have a predetermined spacing in between each other, which is disposed to receive at least a portion of the conduit assembly.

A plant cultivation container is provided which does not need a feed-water tube made of a porous material or the like but the plant cultivation bed material can be made permeated in a relatively short time period. For this purpose, a water reservoir portion for pooling plant cultivation water is provided, the water reservoir portion having a bed material accommodation part for placing a water-absorbing plant cultivation bed material. In the plant cultivation container, the water reservoir portion is provided with a surrounding feed-water channel that surrounds an entire circumference of the bed material accommodation part, and a feed-discharge channel for supplying the plant cultivation water from outside to the water reservoir portion and for discharging the plant cultivation water in the water reservoir portion to outside is provided in communication with the surrounding feed-water channel.

The present invention provides an inverted roofing system and method that is more thermally efficient, inexpensive and quicker to install, better able to withstand environmental conditions, and produces the appearance and some functional benefits of a traditional natural green roof ballast top-layer. It does not require a sloped roof gradient, and is capable of a user controlled mass per square foot roof load. The inverted roofing system and method provides a ballast top-layer that is lightweight, and maintains properties that will prevent wind uplift.

A data center cooling system includes a housing and a number of container data centers. The housing includes an enclosure and a roof. The enclosure defines at least one first air inlet. The roof is attached to the top of the enclosure and defines an air vent. The housing defines a vertical exhaust channel and a plurality of receiving spaces within the enclosure. The exhaust channel communicates with the air inlet. The receiving spaces communicate with the exhaust channel and the air inlet. The container data centers are received in the receiving spaces. A gap is formed between the container data center and the receiving space to allow the air from the first air inlet to flow through the exhaust channel through the gap to expel hot air surrounding the container data centers out of the air vent of the exhaust channel.

A system for harvesting rainwater for use in a skirt building. The skirt building includes a main building and a podium supporting the main building. The system includes: a standpipe; a buffer channel; a filter channel; and a green roof. The green roof includes a vegetation region including a baffled diversion corridor, and a bottom filtering layer including a drainage pipe. The standpipe is arranged on the main building and is connected to the buffer channel where the energy of rainwater flowing out of the standpipe is dissipated. The buffer channel, the filter channel, and the green roof are arranged on the podium, and the buffer channel communicates with the filter channel. The filter channel is connected to the green roof. The filter channel is divided into a plurality of sections respectively filled with different matrix materials.
