The wide usages of masonry materials in construction are always accompanied by great consumptions of energy and resource during their life cycle, so it is necessary to evaluate the EI of masonry materials objectively. This paper uses BEPAS, an LCA-based quantitative EI assessment system developed based on our previous studies, to assess the life cycle EI of three kinds of common used masonry materials: autoclaved flyash brick, sintered clay brick and aerated concrete block. Starting with establishing the environmental profiles at the producing, constructing and demolishing phases of these three materials respectively, the environmental impacts are categorized into three safeguard subjects: ecosystem damage, resources depletion and health damage. Then, based on WTP (willingness-to-pay) method and the updated monetization weighting factors, one integrated EI value per functional unit (10m3) of masonry partition wall is obtained. Finally, a comparative study is conducted on the EI values to analyze and compare the life cycle environmental performance of the three materials, resulting that autoclaved flyash brick is the most environmental friendly in a sharp contrast to sintered clay brick. Results also indicate that reusing more wastes, as well as reducing weight and increasing the volume of unit block are the most effective measures to improve the environmental performance for masonry materials.

The Right

The term, “bioethics” was coined in 1970 by American cancerologist V. R. Potter. In the few decades since, the field of bioethics has emerged as an important discipline. The field has attained a remarkable degree of public recognition in a relatively short period of time. The “right to die” cases such as In re Quinlan placed bioethical issues on the front pages. Although the discipline is of recent vintage, the past quarter century has witnessed a flurry of scholarly activity, creating a substantial body of bioethical literature. Moreover, the bioethics movement has manifested itself in institutional expressions. Universities and medical schools have added courses in bioethics to their curricula. In 1974, federal legislation and regulations mandated that federal grantees conducting human subjects research establish institutional review boards to safeguard subjects’ welfare, and even absent a legislative mandate numerous hospitals created ethics committees. Centers and institutes, devoted exclusively to the study of bioethical issues, have been founded.
