The Benefits of green buildings
Every day there is an evidence for the importance of green buildings and their multiple benefits is emerging, providing the means to achieve a range of global goals such as addressing climate change and accelerating economic growth.
The Green Building is the building that considers environmental considerations at every stage of the construction, namely, design, implementation, operation and maintenance. The main considerations are the design of spaces, energy and water efficiency, resource efficiency, quality of the building’s internal environment and the impact of the building as a whole on the environment. The main between green buildings and traditional buildings is the concept of integration.
Green buildings offer many benefits to many construction industry stakeholders, including building residents and the community as a whole. Green buildings typically include better air quality, abundant natural lighting, availability of views and noise control for occupants of the building, making these buildings a better place and we will discuss the benefits of green buildings.
From the first day of construction, this applies to greenhouses as well as sustainable office buildings and everything that is being built.
Research and studies have confirmed that initial investment in the green design of only 2 percent will result in savings of more than 10 times the initial investment based on a conservative age of 20 years.
Studies show that occupants of buildings with health and comfort are the most productive. A study of 31 green buildings in Seattle showed a 40 percent drop in absenteeism.
Another study showed a 30 percent reduction in the number of sick days among employees of one company.
A 10 per cent increase in net revenue per employee was discovered in another company as companies in green offices also have an advantage in attracting and retaining large employees.
One of the main objectives of green buildings is to improve the quality of air and water for individuals inside buildings. According to an EPA report, the level of indoor air pollution is about two to five times greater than that of open air. The report states that most pollutants are due to materials used in construction and furnishing Building. Other contaminants are volatile organic compounds and occur naturally. The most common are paints, solvents, carpets and cleaning products, so the presence of green building will help to improve and purify the air of many pollutants.
The use of green architecture is one of the ways to help produce less waste using renewable materials such as sustainable wood and plant materials or by re-using secondary industrial products such as sand, burnt coal and demolition debris. Green construction can also help to promote smart growth by taking Human health and safety.
a) Water use efficiency
Green buildings do not know the meaning of the word “waste something,” so these buildings recycle rainwater and gray water and use it to clean the toilet, for example.
b) Energy efficiency
These buildings provide more energy than those built of bricks. It depends only on all energy resources such as solar energy, hydropower and renewable wind energy, which are used for heat and electricity, all of which improve indoor air quality.
C) Efficiency of resources used
Green buildings are constructed from natural, non-toxic, recycled materials that do not cost much like bamboo, straw, recycled metals or environmentally friendly concrete.
Use Natural Energies and Maintain Available Energy:
Utilizing renewable energy sources such as solar heaters, solar photovoltaic panels, wind energy, bioenergy and any other type of clean energy will be reflected in positive results, all of which contribute to the preservation of the environment as clean as possible.
The efficient use of energy is the careful selection of windows, insulating glass that reduces the leakage of heat and the use of insulating materials for walls and ceilings to be used in terms of air conditioning and heating, insulation of air conditioning pipes, the correct status of steam and air condensers, and the use of clean energy in heating and cooling. Many new buildings are isolated using recycled materials such as blown glass fiber. Proper insulation contributes significantly to energy costs in the future.
If we look at modern buildings, most of them depend on the electrical energy of air conditioners, despite the many disadvantages resulting from their use, which affect human health as they emit soil rich in organic matter. These organic materials represent an environment suitable for the growth of fungi and microbes. The objects in the air conditioning pipes, and then flow with the air currents and are distributed throughout all of this construction in addition to the costs of electrical power needed to operate them.
Methods Of Water Conservation Within Buildings:
Water consumption in the home should be minimized by the use of water-saving tools and the use of more efficient systems for water pumping and reuse.
As well as the recycling of gray water (resulting from the use of bathrooms and kitchens ) have a significant impact on reducing water consumption in buildings, In a ground tank treated and filtered using sand, gravel and biological filters and then reused for irrigation of gardens, for example resulting in the production of the least possible amount of wastewater, which helps reduce the harmful effects of water use on the surrounding environment such as marine environments.
Sound Design and Noise Avoidance:
The sound effects on the mental and physical health of the human and have two types of effects:
Good effects: They are produced by beautiful sounds.
Harmful effects: They are caused by loud sounds and noise, and the main sources of noise inside the building are the use of large electrical appliances such as washing machines, dishes and televisions. Noise from outside the building is carried by the air and enters the building through windows, open doors or small openings.
The efficiency of walls in preventing noise transmission depends on its mass; the thicker it is the better in preventing the transmission of noise. Sound insulation materials can be used.
Ways to avoid noise and avoid the inside of the building:
1) Increase the distance between noise source and construction to be protected from noise.
2) Place blanks that are not affected by noise from the vicinity of the noise source.
3) Plant trees by the source of noise where it will have the best effect in reducing the noise coming into the building
4) Create noise barriers from the source of noise such as highways, where these barriers absorb noise and reduce the degree.
The Resilient and Responsible Architecture and Urbanism Conference Will Be Held In 10 April To 12 April 2018 , The aim of this Conference is to exchange knowledge and experience in ramping up the future-proofing of new and existing dwellings and communities, Take The Chance To Publish Your Research On The high-quality publication Organizations Such as Resourceedings” hosted by “SSRN by ELSEVIER”. Publication in a book series by Springer.
