Roof Greening Plays an Important Roal in Environmental Protetction
International green roof popular definition is everything from planting techniques to gas, its coverage is not just a roof planted include balconies, rooftops and balconies, the wall, the top of the underground garage, overpasses, and all with the ground, the soil relative to the green space of the connection of all types of buildings and structures. People under the ecological conditions on the building roof structure characteristics, loads and roof, the growth habit of the construction of green landscape with suitable plant material, through a certain skill, at the top of the building and other special space. Green roof to save the land, to open up the urban space, an effective way of “packaging” of buildings and urban building green art collusion particular note is the role of green roof in the protection of the urban environment can not be ignored. According to scientific measurements, a city roofs utilize green then the carbon dioxide in the city compared with no green lower 85%. Has always attached importance to the greening of Japan and has a world class environmental protection and greening facilities in Germany have reached a very high level in the building on the roof garden. Building design in Japan In addition to increasing the balcony to provide a green area, also the highest level of the roof was built in the “open”, the entire roof together into one, to make it into a vast highaltitude venues, residents can grow flowers planted with their own preferences grass; in Germany further update the buildings shape its structure, buildings built ladder or pyramid residential group, When people arranged from the various forms of roof garden, seen from afar the Banbi Huashan close look also deemed to gorgeous canyon, overlooking the like a giant carpet of colorful, refreshing, beautiful. Major cities in Russia, Italy, Australia, Switzerland and other countries also have a varied and beautiful scenery and a roof garden. The domestic roof garden of a small amount of practice in the early 1960s, has begun, when some cities of Chengdu, Chongqing and other use of the factory floor, office buildings, warehouse roof platform to carry out agricultural and sideline production, the cultivation of fruits and vegetables. The 1970s, China’s first large roof garden built in the 10-story roof of the Guangzhou Dongfang Hotel, which is of the earliest Western synchronization built in accordance with the unified planning the design and construction of the roof garden, gardening methods, to create a local ethnic characteristics of the space environment . The west side of the 1983 Beijing Great Wall Sheraton Hotel in the main building, built in northern China’s first large-scale open-air roof garden on the lower roof. Since then China has successively built Beijing Capital Hotel roof garden, indoor atrium garden of Guangzhou White Swan Hotel, Shanghai Huating Hotel roof garden, Chongqing spring outside floor, opened the prelude of a of construction roof garden in China. Overall, many developed countries, the green roof has developed for decades, both theoretical support and technical support are ripe, and our research and practice on the green roof is just in its infancy. At present, the increasing deterioration of the living environment, building up a lot of green space, a serious impact on the living environment of mankind, the role of the green roof is particularly important at this time. read more →
Will Plastics Be the New Structural Building Material?
Every year, trillions of tons of plastic made products the bulk of which is shopping bags, obsolete electronics, and empty water bottles, get dumped into landfills worldwide. So far, recycling efforts have made barely a dent in this waste pile. But that might change if recycled plastic were to emerge as a core structural component for new home construction. To those builders and suppliers who say don’t hold your breath.one academic who has spent his career working with recycled plastic responds confidently that this evolution is coming. Dr. Tom Nosker of Rutgers University invented a structural composite material made from 100 percent recycled plastic that Axion International now uses to make railroad ties and bridges. Nosker predicts it is very likely? that recycled plastics will be used more widely to build homes. It’s only a matter of time. He tells Builder. Recycled polyethylene has great mechanical properties and is strong as hell. But it’s all going to be about politics.?He notes that some countries already ban wood from being used in structures. With Canada exporting more lumber to China than it does to the U.S., the availability and price of wood for construction becomes less predictable. And plastics should get cheaper as the gap between oil and natural gas prices closes. Indeed, the media have given recent attempts to use recycled plastic as a structural component in home building widespread publicity. A case in point was the opening in Haiti recently of a manufacturing plant devoted to mass-producing bales of compacted recycled plastic bound by wire. The process was developed by Texas-based Ubuntu-Blox, which in June completed a house in Haiti made from about 600 bales. Affresol’s process mixes granulated plastic waste with a mineral/resin compound. The finished product-which pours like concrete and dries in 2.5 hours-is produced for about 12 percent less than standard bricks or blocks, and doesn’t have anywhere near the carbon footprint of composites made from plastics melted at high temperatures. read more →
