Succeeding sustainability terms in construction and building industry isn't about limiting the quantity of building. It's could achieved with considering design and select materials without or with low environmental impact. There are various environmental impacts that are associated with the use of materials during the lifecycle of building materials from cradle to grave, such as: raw material extraction through materials processing, manufacture, distribution, use, repair and maintenance, and disposal or recycling. Life Cycle Assessment (LCA) is the formal methodology and process that investigates the environmental impact of a building material product at every stage in its life. LCA has been widely used in many countries and its current application has been extended to include government policy, strategic planning and product design. LCAs can be costly and time consuming, thus software technology is helped to eliminate these obstacles in material assessment. Many kinds of LCA software exist with different capability whoever the selecting among existing sample is different. This paper is providing critical review and comparison some LCA software and standards with convinced specification. Finally, the process for environmentally sustainable design is highlighted with some standards that exist for LCA.
An overview of Afghanistan's trends toward renewable and sustainable energies

The world requests ever growing energy supplies to sustain economic development and improvement. Renewable and sustainable energy ever more becoming accepted and established a decisive place in energy system of the word due to ecologicallyresponsiveinsight and a decrease in equipment expenses. Consistent with its endowment of energy resources, each country tried to figure out its own energy portfolio and employing technologies, which are economically viable and socially equitable, and have minimal adverse impacts. This article attempts to review all possible renewable energy sources as a substitute of the current energy profile (coal, natural gas, and petroleum) in Afghanistan. The study found Afghanistan power sector as one of the least development sector which its inadequate status is preventing the development of the country as well. Eventhough, the energy is not the only panacea, but cost effective energies in abundant quantity and quality on sustainable foundation will help to reach to demand socio-economic development. The results indicate that Afghanistan due to its natural and geographical situations enjoys important prospective for renewable energy bases such as solar, wind, geothermal and micro hydro power. Renewable energies could offer the ultimate solution for Afghanistan in general, and rural areas in actual. But, switch to altered forms of energy is grounded in multifaceted interations. The study indicates number of issues such as great upfront charges, absence of providers, insufficient funding appliances, and feebleindorsed and methodologicalcapability overwhelm and affected the use of renewable energies and technologies in Afghanistan. However, with sufficient investment and practical stages by government, andnongovernment agencies and the public encourage, these unbound sources could play a vital role not only in Afghanistan's energy supply, but also in poverty reduction, social and political stability, and improving living standard.

The absence of clear instructions for GBMs and the difficulty of precision adjustments of GBM criteria with 3Ps sustainability make GBM selection a challenge. In addition, the consideration of all sustainability factors in GBM selection is a multi-criteria decision problem that requires mathematical techniques such as the multi criteria decision making (MCDM) method. This study applies a hybrid MCDM methodology to resolve multiple incompatible and conflicting GBM criteria to align with 3Ps sustainability. The Decision-Making Trial and Evaluation Laboratory (DEMATEL) was used to analyze the efficacy of and interrelationship between GBM criteria. This tool is a hybrid model using fuzzy analytic network process (FANP) for aligning and ranking GBM criteria based on 3Ps sustainability. Additionally, the study inspects four groups of professionals in Malaysia who involved in GBM selection and modified one of the oldest GBM criteria models considering the criteria identified from a comprehensive literature review. The results show that the relationship between GBMs and sustainability criteria are different based on the separate 3Ps of sustainability. The evaluation and results provide a valuable reference for building professionals to enhance sustainable construction through green materials.

Concrete is the world's most popular construction material, because of the benefits that it can provide for construction industry and structures. Concrete, like other products has environmental effects occurring from it raw material process of resource extraction to producing and transportation. The basic impacts of cement productions are the CO2 emissions, which resulted in direct effects to global warming, raw materials depletion and energy consumption. Cement manufacturers are a source of greenhouse gas emissions, accounting for around 7% to 8% of CO2 globally. It has been proven that half of the CO2 in manufacturing procedure of cement is released by limestone decomposition in the kiln and the other half is due commonly from fuel burning to operate the kiln. This paper draws attention to some different influences of concrete on the environment and highlights the benefits of fly ash concrete as a new finding in the world of construction by comparing its properties and effects with the regular concrete. At the end, some guidelines for decreasing destructive environmental impacts of concrete are suggested. Therefore, in spite of so many initiatives which have been done in the field of construction but still the improvement of eco-friendly materials seems to be lacking and more efforts are needed in the environmental discussions and education of civil engineers.

green construction and sustainability. Malaysia has embarked on initiatives for sustainable development consistent
with global concerns on the environment and sustaining the world resources for the future generations. The issues of
sustainability and green construction have been duly highlighted in the Construction Industry Master Plan (2005-
2015) as being of significant importance for the Malaysian construction industry. In this regard, industrialized
construction has the unique characteristics to respond well to the sustainability challenge facing the construction
industry. Industrialized construction assist adopters in term of cost and time certainty, attaining better construction
quality and productivity, reducing risk related to occupational safety and health. But, despite all those capabilities
most of the construction work in Malaysia is still applying conventional methods which are not often sustainable.
Thus, this study tries to explore obstacles and drivers in steering IBS towards the agenda of green and
sustainability.

towards the agenda of the green and sustainability with respect to Malaysia. Today, sustainability is no longer
considered a buzzword, but a reality that should be applied in policy, practice and management of all sectors of
society. It’s a cornerstone needed by humans to live decently within their own conception of welfare, with respect to
others without compromising the ecosystem as well as social and cultural norms. The pursuit of sustainable
development puts the construction industry at the forefront both globally and nationally due to its total energy,
resource consumption and carbon emission. However, the industry is identified as one of driving forces of the
nations’ economy because of its contribution in generating wealth through constant growth in GDP. In addition, it
influences the development of social and economic infrastructures and provides job opportunities. Based on the
findings, most of the construction work in Malaysia and in the rest of the world is still applying conventional
methods which are not often sustainable. However, IBS has capabilities to be considered as a vital pillar in helping
the government to attain sustainable development when there is a need to balance economic growth, social
expansion and environmental protection. For achieving these gaols it is necessary that more legislation, incentives
and financial supports be considered and launched in the construction industry and governments exploit their
foresight regarding this transition to maximize the potential benefits through policies supporting the development of
the private demand for and supply of activities which meet this agenda. And, all initiatives need to be taken forward
simultaneously by cooperation from all stakeholders.

accompanied by the accumulation of the main human activities such as the economic, cultural,
educational and social ones. Rising population and rapid worldwide urbanization has created
enormous problems of health and environment and have raised concerns about the sustainability of
cities. In this regard, on recreational areas and urban green spaces become important. The quality of
green spaces helps to define the identity of towns and cities, which can enhance their attraction for
living, working, investment and tourism. And, by affording important socio-economic and psychological
needs, enrich human life with meanings and emotions and raise quality of life as key component of
sustainability. In this study, one of famous sample of historical Persian Gardens were chosen due to its
historical background as first sample of Iranian urban green spaces which are still being used actively
by the residents. The issues investigated are functional and emotional dimensions involved in the
experience of garden and its importance for people’s general well-being.

contribution in generating wealth through constant growth in GDP, which influence the development of
social and economic infrastructures, and building, and providing job opportunities. But, against all these
benefits construction industry’ total energy and resource consumption and carbon emission also raise
a growing concerns regarding this industry among experts. Construction industrialization could be
considered as a feasible tool to support the construction industry to achieve sustainable development
in the current process of rapid urbanization. In other words the unique characteristics of Industrialized
Building System have the potential to respond well to the sustainability challenge facing the
construction industry. Thus, this study tries to examine industrialization and its relation and capabilities
towards the agenda of the sustainability particularly with respect to Malaysia.

embodied energy and toxicity but their drawbacks are provided relentless competition between
natural and synthetics fibres. Intrinsically, Natural Fibres are hydrophilic that is leaded to poor
resistance to moisture and incompatible to hydrophobic polymer matrix. This incompatibility of
natural fibres results in poor fibre/matrix interface which in turn leads to reduce mechanical
properties of the composites. This study try to litreature some methods of chemical treatment or
surface modification of Natural Fibres for improving this drawback of natural fibres. The objective
of this research is fungi treatment as Green Surface Treatment that is indicate to environmental
friendlier process. The use of fungi can provide low cost, highly efficient and environmentally
friendly alternatives to natural fibre surface treatment.

all over the world for decades. It is a concern that has
grown out of wider recognition about rising
populations and economic development as well as
global climate and environmental changes. Therefore,
efforts towards stabilizing atmospheric concentrations
of greenhouse gases at a level that will have
acceptably manageable consequences on the global
environment, human health, natural resources and
physical infrastructure have been risen. One of those
efforts is green site design. This paper tries to
introduce green site design, its principle and strategies
which result in cost savings from reduced water and
energy consumption and consequently enhance the
sustainability of a new development.

Buildings largely have become an area of focus for
green investment dollars and the world of building
design has over the last decade been increasingly
going toward green. Green construction is considered
as environmentally friendly because it uses
sustainable, location-appropriate building materials
and employs building techniques that reduce energy
consumption. With global concerns on the
environment and sustaining the world resources for
the future generations, Malaysia has also embarked
on initiatives for sustainable development. This study
reviews green buildings trends, development and
strategies particularly with respect to Malaysian

Traditional scheduling methods of construction have been settled for building of
structures previously but they are not any more
suitable for producing robust work schedules.
Technological innovations have assisted the
construction industry to avoid a lot of uncertain
hazards through management of all resources for
construction in an efficient, effective and affordable
manner. Building Information Modeling or BIM as an
innovation in construction has modified the basis of
this industry by improving cost, scheduling and coordination
of infrastructure projects. Building Information Modeling in terms of 4D modeling saves a lot of time and money over traditional scheduling processes. On the other hand, enhancing the reliability of planning is a fundamental factor to achieve stable construction flow and subsequently,
high productivity and improved product quality. This
paper compares BIM-based scheduling with
traditional method and also will focus on the last
findings of BIM to understand how BIM solves
problems existed in the traditional method of
scheduling.

the clients from the one side and demanding for more profit
by stakeholders from the other side has caused substantial
changes in construction methodologies. One of the most
significant issues which improve the profitability of building
is to use a preventive policy to reduce construction waste.
Different researches and construction waste minimization
techniques have been done so far, but a comprehensive
approach that can be effective in various areas in
construction has not provided. Building information
modeling (BIM) as a feat in construction industry has
developed methods to cut construction wastes in design and pre-construction phase. This paper will focus on the
construction waste origins, current practices of waste
reduction and finally describes the potential application of
BIM to design out waste.

wealth in the world; so, owners are concerned buildings that
more over provide their welfare, can save their investment. In addition, complex problems are shared and impact environment and urban sprawl, like climate change, air pollution, global warming, and etc. Sustainability has been proposed not only to reduce environmental hazards; it can also integrate social economical requirements without compromising the welfare of future generation. In this case, sustainable design consider larger settlement and industrial developments patterns and attempt to make them healthier, least wasteful, and with fewer impact on environment. Further, the concept of constructability that has been offered sequent sustainability during previous fourth decades is a project management technique that reviews construction from start to finish, in order identifying obstacles and use some methods like innovation lead to achieve overall project objectives. Therefore, integration between constructability and sustainable design could provide condition that efficient resource utilization and also, reduce wastage that consequently leads to sustain environment economic and society. In other words, sustainable design and constructability are two components of an efficient design and construction. The purpose of this paper is to review related literatures and find key points between constructability and sustainable design to enhance the quality of buildings and consequently quality of life.
