File Name: difference between green building and sustainable building .zip
Buildings have extensive direct and indirect impacts on the environment.
Academic and policy literature over the past four decades from as early as the s has been, and still is, concerned with understanding and articulating the core principles of sustainable development and sustainable construction or, in other words, sustainable building and construction, which is a holistic, multi-disciplinary approach. The increasing global concern with the maintenance and improvement of the environment, as well as the protection of the human health has become an important aspect to be considered by construction companies worldwide. The chapter falls into two parts.
From the environmental impact perspective, the building sector has a significant effect on the entire environment .
Residential buildings represent a large percentage of the built environment, and the selections of materials and layouts are necessary for the general sustainability. Considerable initiatives have been carried out by the research community worldwide, in order to find alternative sustainable building materials and low technology methods, which result in a more sustainable and affordable construction adhering to the comfort standards needed today.
Adopting green building materials is an excellent approach to meet this target. Selection of construction materials which have minimum environmental burdens is useful in the sustainable development of a country. Therefore, building related contribution to environmental issues is large and therefore essential. Selecting environmentally preferable building products is an excellent method to boost a buildings environmental performance.
While there is obviously an immediate need for new technologies to optimize the application of low-impact building materials, it is also true that there are several technologies or systems, currently in use [7,8,9]. Many have originated from an earlier influx of sustainable housing activism and development, prompted by the s environmental movement , and then boosted by the force for better energy efficient buildings . The objective of the study is to possible explore and highlight how sustainable building material can contribute to lessen the impact of environmental degradation, and create healthy buildings which can be sustainable to the occupant as well as our natural environment.
This might lead to environmental, financial, economic, and social benefits. For instance, savings in operation and maintenance costs in GBs can be realized through the installation of high-efficiency illumination and insulation systems  or through a suitable material selection process that considers, for example, the daylight roof reflection [11,14,].
Other primary advantages of GBs related to indoor environmental quality advancements are the reduction on health costs and the increase on employees' productivity [13,15,16] through their perceived satisfaction towards work areas . Furthermore, intangible benefits, such as the building and builder's goodwill, and perceived added value must also be considered [13,18,19] simply because they could guide the decisions of investors and future owners [15,19].
Despite their demonstrated benefits, GBs are not yet regarded as attractive projects since most builders relate green features with expensive technologies that increase cost e. Nevertheless, a careful design process and a comprehensive material selection method, rather than an elevated investment in technology, may be sufficient to accomplish ideal environmental objectives at a lower cost. In reality, some research supports the insufficient difference between the average investment cost per square foot for some GBs, such as academic buildings, laboratories, community centers, and ambulatory care facilities, and that of non-green buildings with the same characteristics .
Moreover, GBs provide better dividends in the long run [13,15,16] recovering up to 10 times the green premium through the realization of anticipated benefits . The achievements of a GB will depend on the quality and effectiveness of the installed green systems.
Therefore, the market demands a common approach to distinguish GBs from traditional buildings through the use of standard, transparent, objective, and verifiable measures of green that will ensure that the minimum green requirements have been achieved. Building materials problemThe material challenge for buildings usually takes various forms. As stated, the grey energy and emissions must be regarded, and the production of building materials involves the use of more high value energy and resources in comparison with building operations.
There are also environmental issues with the by-products of material used in buildings, and there are limitations on the extraction of resources used in numerous building ingredients. One should additionally consider the infrastructure used to support the built environment. There are lots of technological advances that need to be carried out to resolve the complications of resource depletion, corrosion, pollution, durability, lifespan, etc.
Firstly, new construction needs to be constructed more sustainably so that it not just reduces negative aspects of construction and operations, but that it primary boosts building lifespan, which can be carried out by eliminating design features that will be rapidly outdated. Also all required factors with minimal lifespans should be designed for recycle or raw-material-recovery. This must be attained in all aspects by carefully breaking down the complexity of the building into its components, and comprehending virtually any trade-offs among integrated systems so that a completely sustainable solution can be achieved.
This can be assisted by an awareness of the rapidly growing array of materials readily available for build structures, enclosures and systems.
Lastly, with regards to the end of lifetime of a building, there needs to be extremely careful consideration for the processing of the materials. This should be considered previously during the design stage of any building, where composites that are hard to handle are minimized. Materials should be used that can be immediately recycled without the need to remanufacture them.
If they cannot be immediately reused, they can be recovered as raw materials. If they should be reused, they should be utilized at the same level of quality, thereby eradicating any down cycling or waste. Material selectionThe application of stable, attractive, and environmentally responsible building materials is a key ingredient of any high-performance building effort.
The utilization of natural and healthy materials contributes to the wellbeing of the occupants and to a feeling of connection with the bounty of the natural world. Many building materials have considerable environmental effects from pollutant releases, habitat destruction, and depletion of natural resources.
This will happen during extraction and acquisition of raw materials, production and manufacturing processes, and transportation. In addition, some construction materials may harm human health by exposing workers and building occupants to toxic and hazardous chemicals.
Consequently, recognition and selection of environmentally preferable materials for use in construction activities at pre building phase present an opportunity to restrict such environmental and human health impacts.
Selecting environmentally attractive materials with minimized environmental impacts is generally achieved through the process of resource conservation and selection of non-toxic materials. The resources used to manufacture construction materials affect the environment by depleting natural resources, using energy, and releasing pollutants to the land, water, and atmosphere.
Materials which contain irritating, odorous, hazardous, or toxic elements adversely impact human overall health throughout-gassing of volatile components or direct contact. Preferably, materials selections can be made based on a rigorous assessment of environmental burdens through-out the entire of the product or material.
This process, referred to as environmental life-cycle assessment, is rarely feasible for most building procurement decisions. It is possible, however, to apply life cycle thinking to evaluate what is known about the environmental performance of products and make wise selections. These costs are paid not merely by the client, but also by the owner, the occupants, and the environment. The principles of Life Cycle Design offer essential guidelines for the selection of building materials.
Every phase of the manufacturing process, from gathering raw materials, manufacturing, distribution, and installation, to ultimate recycle or disposal is inspected for its environmental impact. A material's life cycle could be well organized into three stages, Pre-Building, Building, and Post-Building .
These stages parallel the life cycle phases of the building itself. The assessment of building materials' environmental impact at every phase enables a cost-benefit analysis over the lifetime of a building, instead of merely an accounting of initial construction costs.
Pre-Building phaseThe Pre-Building Stage explains the production and delivery process of a material up to, but not including, the point of installation. This consists of finding raw materials in nature as well as extracting, manufacturing, packaging, and transportation to a building site. This particular stage has the most possibility of creating environmental destruction. Knowing the environmental impacts in the pre-building phase will result in the wise selection of building materials.
Raw material procurement methods, the manufacturing process itself, and the distance from the manufacturing location to the building site all have environmental implications. An understanding of the beginning of building materials is vital to an understanding of their collective environmental impact when indicated in the sort of a building . Building phaseThe Building Stage refers to a building material's useful life.
This stage commences at the point of the material's assembly into a structure, involves the maintenance and repair of the material, and goes all over the lifetime of the material within or as part of the building.
The material waste generated on a building construction site can be considerable. The selection of building materials with regard to minimized construction waste, and waste that can be reused is crucial on this stage of the building life cycle. Long-term exposure to specific building materials may be harmful to the overall health of a building's occupants.
In spite of an increasing awareness of the environmental health problems regarding exposure to a number of products, there is little focus in reality schools on picking materials based on their potential for out gassing harmful chemicals, demanding regular maintenance with such chemicals, or requiring regular replacements that perpetuate the exposure cycle.
Post-Building phaseThe Post-Building Stage refers to the building materials when their performance in a building has run out. At this stage, a material could possibly be recycled in its entirety, have its elements reused back into other goods, or perhaps be thrown away. From the perception of the designer, perhaps the minimum measured and least recognized stage of the building life-cycle occurs when the building or material's useful life has been exhausted. The demolition of buildings and clearance of the resulting waste has a substantial environmental cost.
Degradable materials may generate harmful waste, alone or even in mixture with many other materials. Inert materials consume gradually scarce landfill space. The adaptive recycle of a present structure sustains the energy that went into its materials and construction. The energy embodied in the construction of the building alone and the manufacture of these materials will be wasted if these resources are not effectively utilized.
Meanwhile Experts selected three categories of criteria, in accordance with the material life cycle, which can be used in considering the environmental sustainability of building materials. The existences of one or two of these components in building materials allow it to become environmentally sustainable.
Some of the components of sustainable building material widely known are listed in In the CIB report on agenda 21 on sustainable construction, states that different nations have their own different strategy and priorities regarding principle of sustainable construction .
The report additionally suggests that the primary focus of sustainable construction and design in universal approach is ecological impact to the environment. Fisher outlined five principles of sustainable design in which sustainable building material had been highly recommended . Healthy interior environmentAll possible measures are to be taken to ensure that materials and building systems do not emit toxic substances and gasses into the interior atmosphere.
Additional measures are to be taken to clean and revitalize interior air with filtration and planting. Energy efficiencyAll possible measures are to be taken to ensure that the building's use of energy is minimal. Cooling, heating, and lighting systems are to use method and products that conserve or eliminate energy use. Ecologically benign materialsAll possible measures are to be taken to use building materials and products that minimize destruction of the global environment.
Environmental formAll possible measures to be taken to relate the form and plan of the design to the site, the region, and the climate. Measures are to be taken to relate the form of building to a harmonious relationship between the inhabitant and nature. Good design. All possible measures are to be taken to achieve an efficient, long lasting, and elegant relationship of use areas, circulation, building form, mechanical systems and construction technology.
Additionally, Kim and Rigdon  highlight about three major principles on sustainable design which are shown in figure 2, as the matter of fact, this principles deal with an economic sustainability, a functional sustainability, an environmental sustainability, a social and human sustainability. Sustainable building materials by definition are materials which are domestically created and sourced which decreases transportation costs and CO 2 emissions, they could consist of reused materials, they possess a lower environmental effect, they are thermally effective, they need less energy than conventional materials, they make use of renewable resources, they are lower in harmful emissions and they are economically sustainable.
A sustainable building material needs to be used properly and contextually in every community development. The application of sustainable building materials not just minimizes transport costs, carbon emissions, and in most cases materials costs, it also offers employment and skills development opportunities for community members.
They provide some of the most effective means to achieving a range of global goals, such as addressing climate change, creating sustainable and thriving communities, and driving economic growth. Highlighting these benefits, and facilitating a growing evidence base for proving them, is at the heart of what we do as an organisation. The benefits of green buildings can be grouped within three categories: environmental, economic and social. Here, we provide a range of facts and statistics from various third-party sources that present these benefits. One of the most important types of benefit green buildings offer is to our climate and the natural environment.
Although green design is more related to environment concerns, sustainable design goes way beyond that. First, before we explain the difference, you have to keep in mind the three pillars of sustainability : economic development, social development, and environmental protection. Both address the pillar of environmental protection , like water pollution, indoor air quality, and waste management. Are you still confused? A large portion of the bamboo flooring available in the world is produced in China, which means that it needs to be transported by ships and trucks to its final destination. Consequently, it contributes to more pollutants in the air.
T he research is concerned with studying the characteristics of Sustainable Architecture and Green Architecture, as a general research methodology related to the specific field of architecture, based on the differentiation between two generic concepts, Sustainability and Greening, to form the framework of the research specific methodology, where both concepts seem to be extremely overlapping for research centers, individuals, and relevant organizations. In this regard, the research tend towards searching their characteristics and to clearly differentiates between the two terms, particularly in architecture, where the research seeks understanding sustainable and green architectures, how they are so close or so far, and the possibility of finding common features between them that might make them as a one synaptic concept. The research problem focuses on that there is no clear differentiation between sustainable and green architectures, what causes a matter of confusion and unclarity in dealing with building projects what affects understanding processes and procedures during the progress of design, construction, and operation, within the whole building life cycle, and this leads to a defect in understanding the formation of building design, construction and operation. The research hypothesis shows that environmental and architectural indicators can form a mechanism to differentiate between sustainable architecture and green architecture. This mechanism depends on several elements that form, together, the hypothesis testing tool, and in turn, this tool will become a method to verify the hypothesis reaching accomplishing the goal of the research formation of a theoretical framework that enable to differentiate between sustainable and green architectures. The research methodology depends, also, on the effects of factors like economy, technology, welfare, and else, with focusing on the green growth and sustainable development as distinguished statuses in the two concepts, to reach establishing a comparative study and understanding their developing stages and clarifying the main differences between sustainability and greening, architecture wise, to form the elements of the theoretical framework to differentiate between sustainable architecture and green architecture.

Sustainable architecture is architecture that seeks to minimize the negative environmental impact of buildings by efficiency and moderation in the use of materials, energy, development space and the ecosystem at large. Sustainable architecture uses a conscious approach to energy and ecological conservation in the design of the built environment. The idea of sustainability, or ecological design , is to ensure that our use of presently available resources does not end up having detrimental effects to our collective well-being or making it impossible to obtain resources for other applications in the long run. Energy efficiency over the entire life cycle of a building is the most important goal of sustainable architecture. Architects use many different passive and active techniques to reduce the energy needs of buildings and increase their ability to capture or generate their own energy.

Она хотела только одного - поскорее уйти. Стратмор на минуту задумался. - Не спрашивай меня, как это случилось, - сказал он, уставившись в закрытый люк. - Но у меня такое впечатление, что мы совершенно случайно обнаружили и нейтрализовали Северную Дакоту.
- Нужен код. - Код? - сердито переспросила. Она посмотрела на панель управления.
Там, где только что было его плечо, оказалась черная пустота. Она шагнула вперед, но и там была та же пустота. Сигналы продолжались. Источник их находился где-то совсем близко.
Вращающиеся огни напоминали вертолеты, идущие на посадку в густом тумане. Но перед его глазами был только Грег Хейл - молодой криптограф, смотрящий на него умоляющими глазами, и выстрел. Хейл должен был умереть - за страну… и честь.
Городские огни сияли, как звезды в ночном небе. Он направил мотоцикл через кустарник и, спрыгнув на нем с бордюрного камня, оказался на асфальте. Веспа внезапно взбодрилась. Под колесами быстро побежала авеню Луис Монтоно. Слева остался футбольный стадион, впереди не было ни одной машины. Тут он услышал знакомый металлический скрежет и, подняв глаза, увидел такси, спускавшееся вниз по пандусу в сотне метров впереди. Съехав на эту же улицу, оно начало набирать скорость, двигаясь прямо в лоб мотоциклу.
Thus green evokes small incremental improvements in social practices, modern technology, and human habitats, while sustainability implies a revolution in organizing our personal and collective lives and inhabiting the planet.
