There has been a steady rise in popularity for green roofs, and similar environmentally friendly alternatives to slate. Over the last six months, Elon Musk has pitched his solar roof tiles. One issue with green roofing is, supposedly, their flexibility. Until now.
Bridgman and Bridgman of Wolverton, near Milton Keynes, came up with an answer for a pumping station in Kingston-upon-Hull. The company also worked on living roof designs for the London Olympic Games in 2012. At the pumping station, for the Bransholme and Kingswood catchment area, its green roof has broken new ground. The green roof is made up of 42 trays.
Each tray can be lifted off, which allows Yorkshire Water to access the storm water screw. Either one or more, or all 42 trays can be lifted off. The roof cover is 500 square metres. It pumps out four million tonnes of water per second. This is equal to filling an Olympic-sized swimming pool every two minutes.
Aesthetically pleasing as well as environmentally friendly
As the £16 million project is close to nearby housing estates, its role as a good neighbour goes beyond its environmentally friendly credentials. The green roof also makes for a more pleasing aspect compared with traditional roofing materials.
What is a green roof?
A green roof refers to any kind of roofing which is designed to reduce the carbon footprint of any building. It is a living roof that is partially or wholly covered in turf, wild flowers, or sedum. A waterproofing membrane and drainage channels need to be placed below the foliage. This stops the roof from caving in.
