Abstract: The introduction of life cycle assessment (LCA) to the building industry is important due to its ability to systematically quantify every environmental impact involved in every process from cradle to grave. Within the last two decades, research on LCA has increased considerably covering from manufacturing of building materials and construction processes. However, the LCA application for buildings in Asia are limited and fragmented due to different research objectives, type of buildings and locations. This paper has attempted to collect and review the application of LCA in the building industry in Asia from the selected publications over the last 12 years, from 2001 to 2012. The result shows that most LCA research basic methodology is based on International Organization of Standardization (ISO) 14040 series but with variance. It is found that the operational phase consume highest energy and concrete responsible for the highest total embodied energy and environmental impact. It also suggested that building material with low initial embodied energy does not necessarily have low life cycle energy. Overall, findings from LCA studies can help to make informed decisions in terms of environmental impact and help realizing sustainable buildings in the future.

Abstract: The global environment is deteriorating gradually after the middle of the twenty century, the global aims at sustainable developments and positively research related policies and programs. SBTOOL is frequently referred to as the research tool of case assessment by many countries in International Conferences of sustainable development; SBTOOL is recognized internationally as assessment tool contributable to the development of sustainable buildings in various regions due to its elastic adjustment. Thus this study uses SBTOOL to access the relevance between EEWH and the results of assessment on the examples by SBTOOL based on 10 examples of the residence buildings granted as Taiwan Qualified Green Buildings, analysis the influence of the “Duplex and Single-family Houses” and “Architectural Floors” on the result of the assessment to provide reference for the international integration of Taiwan sustainable buildings.

Abstract: Durable, renewable, and affordable are the three characteristics of the adobe brick, one of the widely used construction material in human civilization, but is always neglected. Traditionally, price has been the foremost consideration when comparing similar materials or materials designated for the same function. That is why by the post-war period, the concrete was adopted as a universal building material in response of the massive housing demand. The intergovernmental concerns never took into consideration both the sustainability factor and the cultural one, not until the 1990s when research on climate change expanded and the sustainable development took an important place in the different academic cross fields: engineering, biology, technology and architecture. The main focus by then was the reduction the CO2 gas emissions emitted by the building sector which is now approximately 30% of the global energy-related. Researchers are focusing on creating a completely new green eco-material an alternative to the concrete, but in this paper, I will demonstrate why is it worth to reinvigorate centuries-old eco-construction material. Adobe bricks are currently the best choice to built affordable housings in response to the chronicle demand. Not only they have a track record that makes their thermal mass performance easier to evaluate, but also they can last 400 years or more when properly maintained. Comparatively, new technologies require testing over time to determine their long-range effectiveness.

Abstract: Vernacular architecture is a term used to categorize methods of construction which use locally available resources and traditions to address local needs. This paper addresses the relation between Chinese vernacular architecture and locally sourced materials, which shows that the application of the vernacular materials is the primary component of the sustainable value of vernacular architecture. To assess the contribution of these materials for sustainability, a comparison with industrial materials at level of environmental indicators was established. This paper highlights the advantages of using local materials and techniques as a factor of local socio-economic development.

Abstract: The use of coarse recycled aggregate in concrete is already accepted in the Czech Republic but with specific restrictions. The problem is the use of fine recycled aggregate (FRA) in concrete. This paper is focused on behavior of concrete containing FRA. FRA, which originated from recycling plant in the Czech Republic, was used in an experimental part. FRA was obtained from demolished and crushed concrete structures. Four concrete mixtures were designed and prepared. The first concrete mixture was reference which did not include FRA. Natural sand was replaced by FRA in other concrete mixtures in varying ratio. There were tested physical, mechanical and deformation properties of concrete. According to test results it is possible to say that the use FRA as partial replacement of natural sand in concrete mixtures.

Abstract: Earthen buildings come in a vast variety of shapes and sizes, made from materials like fired clay, compressed dirt and a mixture of clay, sand, straw and water. People have been using various forms of earth to build structures for centuries. From underground green homes to other futuristic green houses. This paper is included 6 diverse examples of structures made from earthen materials in Iran that used Iranian architecture in their works. The buildings are included special mortar called Sarooj in their construction. The result has shown the earthen buildings create safer, more people-friendly buildings. The earthen buildings are very low in embodied energy, and extremely comfortable to live in. With captivating discussion, Earth Architecture showcases the beauty and simplicity of one of humankind's most evolved and sophisticated building technologies in Iran and the world.

Abstract: Since previous instances the requirements of environmental safety, suitability and responsibility of buildings have increased. The criteria of sustainability are included in building environmental assessment systems and tools used in different countries for evaluating their sustainable and environmental performance. The purpose of this paper is to introduce the one of most significant filed in building environmental assessment system (BEAS), which was developed at the Technical University of Košice. The Slovak system was developed on the basis of existing systems used in many countries. BEAS as a multi-criteria system which is incorporated in proposed main fields: site selection&project planning; building construction; indoor environment; energy performance; water management and waste management. Selection of building materials and structures is very important in term of embodied energy and emissions of pollutants. The field of building construction will be introduced in the paper. The aim is also weighting and analysis of significance of building construction indicators in system BEAS with is applicable in Slovak conditions.

Abstract: To realize a higher quality sustainable building, it needs more efficient design methodology from the beginning. Through theoretical study, case analysis and interview practice, based on “the integrated status of generation and evaluation” in building design process, and improving the" sustainable performance" effectively as the core goal, a new methodology named "IMGESB" (Integration Mechanism of Generation-Evaluation for Sustainable Building) is established. Through an experimental design for an office building, IMGESB is applied, tested and optimized. Finally the authors summarized the corresponding design procedures for the framework, which consists of four basic execution modules. IMGESB is not only a design methodology, but also a kind of design ideology in architecture. It can ensure maximize the sustainable goal from the view of procedure in the design process.
