This article is about sustainable construction principles. This requires close cooperation of the contractor, the architects, the engineers, and the client at all project stages. The Green Building practice expands and complements the classical building design concerns of economy, utility, durability, and comfort. Currently, World Green Building Council is conducting research on the effects of green buildings on the health and productivity of their users and is working with World Bank to promote Green Buildings in Emerging Markets through EDGE Excellence in Design for Greater Eco friendly construction techniques pdf Market Transformation Program and certification.
A similar concept is natural building, which is usually on a smaller scale and tends to focus on the use of natural materials that are available locally. Other related topics include sustainable design and green architecture. Sustainability may be defined as meeting the needs of present generations without compromising the ability of future generations to meet their needs.
Although some green building programs don’t address the issue of the retrofitting existing homes, others do, especially through public schemes for energy efficient refurbishment. Green construction principles can easily be applied to retrofit work as well as new construction. A 2009 report by the U. General Services Administration found 12 sustainably-designed buildings that cost less to operate and have excellent energy performance.
In addition, occupants were overall more satisfied with the building than those in typical commercial buildings. Globally, buildings are responsible for a huge share of energy, electricity, water and materials consumption.
The building sector has the greatest potential to deliver significant cuts in emissions at little or no cost. 9 billion tonnes of CO2 annually. If new technologies in construction are not adopted during this time of rapid growth, emissions could double by 2050, according to the United Nations Environment Program.
Green building practices aim to reduce the environmental impact of building. Since construction almost always degrades a building site, not building at all is preferable to green building, in terms of reducing environmental impact. The second rule is that every building should be as small as possible.
The third rule is not to contribute to sprawl, even if the most energy-efficient, environmentally sound methods are used in design and construction. Buildings account for a large amount of land.
Taipei 101, the tallest and largest green building of LEED Platinum certification in the world since 2011. 1962, is considered to be one of the first initial efforts to describe sustainable development as related to green building. The green building movement in the U. There are a number of motives for building green, including environmental, economic, and social benefits.
However, modern sustainability initiatives call for an integrated and synergistic design to both new construction and in the retrofitting of existing structures. Also known as sustainable design, this approach integrates the building life-cycle with each green practice employed with a design-purpose to create a synergy among the practices used. Green building brings together a vast array of practices, techniques, and skills to reduce and ultimately eliminate the impacts of buildings on the environment and human health.
It often emphasizes taking advantage of renewable resources, e. Many other techniques are used, such as using low-impact building materials or using packed gravel or permeable concrete instead of conventional concrete or asphalt to enhance replenishment of ground water. While the practices or technologies employed in green building are constantly evolving and may differ from region to region, fundamental principles persist from which the method is derived: siting and structure design efficiency, energy efficiency, water efficiency, materials efficiency, indoor environmental quality enhancement, operations and maintenance optimization and waste and toxics reduction.
The essence of green building is an optimization of one or more of these principles. Also, with the proper synergistic design, individual green building technologies may work together to produce a greater cumulative effect.
