We live in this beautiful world which is an ultimate creation of the Almighty. But this usual world has got some unusual problems and those problems are created by us. We claim the world as our own but we can’t make its environment a fresh one. Because we are always busy making it polluted and giving it a harsh feedback. But now it’s the time to change this habit and sustain the world’s worst situation and give a ray of hope of survival.

The topic of Green Technology helps this cause. Because the amount of carbon-di-oxide we are spreading each and every day, it will make that thing precise and create a fresh environment where everything will be genuinely natural. The topic of Green Technology is being illustrated below: In modern construction, a thoughtful integration of Green Building technology can make a tremendous difference in an overall appeal of a newly constructed building.
Green Building helps preserve the external environment and provides great benefits to Humans through the use of environmentally safe and energy efficient building materials, efficient use of natural resources, human safety, wellbeing and health and wellness considerations. [pic] Figure: The Blue print of Green Technology What does green Building mean? Green Building is a fairly broad concept, but the core ideas of green building have the following aspects: ? Environmentally Friendly
It simply means two things; constructing the building is safe for the surrounding environment and will not significantly interfere with the wild life, its patterns of daily life, and that it will not negatively affect the natural environment. Nearby, It also means that building is constructed from environmentally friendly materials that are available locally and that the construction process is well designed to reduce the unnecessary pollution and negative effects on the environment. ? Efficient use of Resources
In green building practices, efficient use of resources means using water saving faucets and plumbing elements, energy efficient lighting units and passive solar design. It also involves, the use of energy efficient building materials aimed to attain highly energy efficient building envelope with well insulated walls, floors and ceilings. A well insulated building envelope will helps keeping building cooler in the summer and warmer in the winter. Reduced energy consumption provides financial benefits for the building owners and helps reduce the carbon monoxide footprint of the building on the environment. Designed for health and wellbeing of the building occupants. Another important feature of a green building is its design aimed at providing comfortable and safe environment for the human occupants. It means that building will be pleasant and safe for people to be in. It could contain the elements of intuitive floor plans, spacious and well lit hallways, fresh-air circulation and monitoring units, dampness and temperature controls. Green Building Benefits The most fundamental benefit of Green Building is that it is environmentally friendly and safe for people occupying the building.
A well designed and constructed green building is well integrated into the environment in which it is built and does not detract from it. It is pleasant and safe for people who use the building on a daily basis. Its aesthetic appeal of carefully designed and well integrated architectural features, such as efficient use of space, intuitive layouts and pleasant lighting offers psychological benefits to people. While, elements such as clean air monitoring and circulating systems, handicap access, clean water and other elements make it safe and beneficial to human health.
Another important benefit of Green Building is Energy Efficiency, which results in reduced energy consumption for AC and Heating needs. It may feature elements like effective use of natural lighting, cool roof and wall panels, and green energy generating systems all aimed reducing energy consumption, which results in cleaner environment and direct cost savings to the building owners. Green Building Materials Sustainability and environmental friendliness are two key requirements to green building materials. Many green building materials also offer energy efficiency benefits.
For instance, use of metal in residential and commercial construction is considered environmentally friendly because metal is recyclable and long lasting building material. Bamboo is another green building material because it grows quickly and thus can be easily sustained. Specially grown Cedar can be considered sustainable building material when it’s grown locally and cut in a sustainable manner that will ensure future growth and availability. Such a building is designed as per rules of the Leadership in Energy and Environmental Design (LEED), a rating system devised by the United States Green Building Council.
LEED was launched in an effort to develop a ‘consensus-based, market-driven rating system to accelerate the development and implementation of green building practices. Green Energy Generation Systems Energy Generating systems are considered to be the most expensive elements of a green building design, but the initial cost of this type of investment is justified when calculated for future energy savings for the building owner. It is also environmentally sound choice that not only results in free energy, but also earns LEED / green building credits to the building owner.
Two most commonly used green energy generating are solar and wind electricity generating systems: ? Solar Power System The use of solar energy in green building can provide free electricity for the building owners. Solar panels can be installed on the roof top of the building where the solar energy will be converted to electricity. ? Wind Turbine Energy Another way to generate electricity is through the use of wind energy. Wind turbine can be set up in pathway of winds, which can provide significant amount of free electricity for the building owners.
Green Building Guide to Costs and Prices Without a doubt, building green is initially pricier than the cost of conventional construction, but from a long term perspective integrating green building elements will result in energy savings and longer lasting building that will pay for the difference in initial investment and then some. Green Building for Residential Use Homeowners can greatly benefit from the use of green building technology in new home construction and for the existing homes.
In fact, there are quite a few green building elements that homeowners of existing homes can benefit from: ? Use of energy efficient windows and blinds Replacing existing windows with energy efficient ones will increase the existing insulation level / R-value of your home, which will help keep your rooms warmer in the winter and cooler in the summer. Installing mini window blinds or other horizontal blind treatments will further help maintain the home’s temperature and can easily be adjusted to maximize the use of natural light. pic] Figure: Green Technology oriented building ? Insulating Walls, floors, and ceilings in your home A well insulated home can help save well over fifty percent on your heating bill in the winter, and lower your cooling bill in the summer. A well insulated building will not leak warmer air out or allow cooler air in the winter, and will provide for similar effect in the summer. Not only will well insulated walls and ceilings help you save money by reducing your energy bill, but it can also help the longevity of your home.
Green Building Technology in Bangladesh Prospective The green technology is gaining ground in Bangladesh, as several sectors are adopting the innovations, thanks to growing campaigns against carbon emissions, the lead contributor to global warming. The concept — ‘be green and make business green’ — is up in the air. It is hopeful that, a fall in prices of green technology-based products on the global market caused by recession has attracted more entrepreneurs to such business, which ultimately pushed the growth up.
In an effort to reduce carbon emission, Bangladesh is already started to using green building technology to replace the over 150-year-old traditional method in the country’s construction sector and the first-ever “carbon-neutral” factory is to be established on the fringes of Dhaka, by mid of 2011. The Green Technology is a broad concept with a short message. Return the world in its own glory of mildness. If we make so it will be a great achievement and a matter of relief also.
