PROMOTING THE FUTURE Green Building
PROMOTING THE FUTURE Green Building

Legionnaires incidents regularly reported epidemic of the 1976 Convention in Philadelphia in the Bellevue Stratford Hotel and the Hotel Croatia. The source of the bacteria had contaminated the water used to cool air in the system of air-conditioned hotel. Furthermore, people dream of living longer in their seventies, eighties, nineties and even. These two cases and incidents certainly indicate the effect of poor indoor air quality in human life. Sometimes life does not sound and strict dieting or excessive exercise, but the right place to live. This is why Green building is ideal for people who care about good quality of life, an important issue in recent times. Unfortunately, only a few half-o the confidence of upper-class urban residents and suburban or even know the health benefits of green building environment.
Typically, the houses we live in are often made of wood or concrete, causing some of the dilemmas and adversity. green building practices tend to reduce the environmental impact of buildings. The Buildings account for a large number of land use, power and water consumption, air and climate change. Overall, buildings consume a little less than half the power total and eighth of the total amount of water consumed in the United States and the European Union.
The question of the construction of poor quality is not just the atmosphere: individuals are affected much. For example, American or European style spends 90 percent of their time indoors of sound, which has at least two times more polluted air exterior. Mortality and morbidity associated with this is well established in the literature of science. The air quality also causes a financial hardship that the loss of health productivity and cost tens of billions of dollars annually to the nation. Buildings release large amounts of particulates and sulfur dioxide and produce building materials first. If particulate matter and sulfur dioxide are harmful to human health, building materials and the leading cause of issues solid waste management waste and global warming.
Green building construction avoids the pitfalls of both conventional and offers residents a good indoor environment healthy. Green building brings together an infinite range of practices and techniques to reduce and eliminate the impacts of buildings, environment and human health. Innovations in green building and inside the building are increasing day by day. Rocky Mountains of Colorado Mountain Institute has a garden that promotes the creation of green bananas, oranges, alligators, avocados, grapes, papaya and passion fruit, even in the mountains to 104 ยบ F. Materials construction typically considered "green" renewable plant materials include bamboo (bamboo grows quickly) and straw, wood forest, the size and recycling of stone, recycled metal and other products that are safe, reusable, renewable and / or ecological (eg wool linoleum panels with rolled paper, Adobe, compressed and clay, clay, vermiculite, seagrass, cork, coconut, patches of wood fiber, calcium, sandstone, concrete high and ultra high performance, etc.).
ING Bank Building in Amsterdam is also an excellent example of the positive benefits of green building. It is a organic construction with natural materials, natural light and small interior gardens with waterfalls. natural ventilation by opening windows is used instead of air conditioning. A cogeneration system powers an absorption refrigerator by the residual heat drying. The cost is $ 1,500 cheaper than many banks to take five times more energy. Often buildings ecological measures to reduce energy consumption. To increase the efficiency of the building envelope, which can use windows high performance insulation in walls, ceilings and floors. In addition, the window position actual days (lighting) can provide natural light and reduce the need electric lighting. In conclusion, the creation of on-site renewable energy through the solar, wind, hydro or biomass, including reducing the environmental impact of construction.
Often emphasizes the use of renewable resources, eg, using sunlight through passive and active solar energy, and use of gardens of vegetation by the rain of green roofs, and reducing runoff. Other techniques of interest concentrates as gravel for parking as a substitute for concrete or asphalt to improve the drainage of groundwater are also used. The building De Montfort University, Queen's, the largest building natural ventilation of Leicester in the UK region can run shell for the occupants Windows can use to regulate their conditions of comfort. The air circulates throughout the building via the chimney effect. Heating is achieved through the use of passive solar design and the gain heat internal occupants and equipment. In fact, a collection of small buildings Nationally, a huge brick masonry structure has magnificent polychrome by local masons and provides the thermal mass of the structure. Carefully designed overhangs and helped close a trace of sunlight during the cooler months and hangs during the heat of summer. Classrooms high in this building have daylight and virtually no power light.
Green architecture is also reduced waste of energy, water and materials used during construction. In the construction phase, one goal is to reduce the hardware landfills. Well-designed buildings also help reduce waste generated by occupants and providing on-site solutions such as compost bins to reduce the material destined for landfill. The Passivhaus Darmstadt, Germany, uses only 10 percent of the energy required by other houses in the city and only 25 percent of the typical power. Instead of being dark and repressive that it might be the case, the Passivhaus is dazzling and cheerful and very connected to nature.
Through the collection of waste at the origin of man and implementation of a centralized facility for the production of biogas with biological waste, fertilizers can be produced. This idea has been verified by a resolution Lubeck in Germany in late 1990. Practices like these are available in the soil of organic nutrients and create carbon sinks to remove CO2 atmosphere, offsetting emissions of greenhouse gases. The production of synthetic fertilizers is also more costly in energy than the process.
Why is green building is not used more often? The answer lies in the fears and assumptions made for overtime in the sector responsible construction. The environmental impact of buildings is underestimated, while the apparent costs of green building exaggerated. A recent study by the Council World Business Council for Sustainable Development states that development costs are overstated by 300 percent green. Some owners do not take time to investigate the benefits green building. Some lack the knowledge and experience in construction and rely too much on older technology and regulation, without regard to quality that is often lacking. Quick cases also abound among lenders and donors fear the cost risk. They may think that because the wood and concrete are so profitable, should not be omitted.
Apparently no concern to the owners that green buildings generate greater benefits in health, welfare and productivity (thanks to daylight). resource consumption is minimized, construction waste is low, the reuse of resources is maximized, natural environment is better protected, energy efficiency is higher and human health has been improved thanks to the absence of toxic substances. Those who care about quality of life need to carefully consider green building buildings with the most common, but less available. They may be surprised by the healthy lifestyle comes from green building. According to EPA, this reduces the amount of natural resources buildings consume resources and the amount of contamination is crucial for sustainability future.
