Green building index is considered as the rating tool for evaluating the siting, design and performance of\r\nbuildings and infrastructures based on worldwide acceptable six main criteria�s It was invented after the Kyoto\r\nprotocol, Japan, on 11th of December 1997 and the adoption in Marrakesh in 2001 by the United Nations and her\r\nsubcommittee. It was developed in the built environment industry by the Government support of each country to\r\ncombat the issue of green house gas emission. Carbon dioxide is acclaimed as one of the main greenhouse gas\r\nemission which is mainly through the activities of human race in the world resulting into global warming hence\r\nthe effort to make the environment lighter enough to inhabit. Construction industry was assessed through studies\r\nto be contributing 5% of the world total carbon dioxide emitted through cement production. It was also claimed\r\nthat a tonne of concrete produces carbon dioxide in the range of 0.05 to 0.13 tonnes. Foam concrete being a new\r\ninnovative green technology material for sustainable building and civil construction needs to fulfill the criteria�s\r\nof this rating tools for it to be considered as sustainable materials. This paper study the assessment of this\r\nlightweight concrete material in view of green building index criteria�s and the result are hereby analyze and\r\nconcluded that foam concrete can be effectively used as sustainable material for building and civil engineering\r\nconstruction....
Earthquake is one of the destructive events in the world. Prediction of earthquake is not feasible at all.\r\nIn the horizon, earthquakes of different intensities and magnitudes occurred. So it is a threat to all\r\nespecially the tall structures of the mega cities. Due to shaking of ground surface, the substructure as\r\nwell as the superstructure is vibrated. During earthquake, there will be a drift on the high rise\r\nstructures. Then it can be included that the more the height, the more the drift. The drift of the structure\r\ndecreases with increase in the width of the structure. So our concern is to calculate the drift of tall\r\nstructures due to the vibration of ground. Hand calculation and programming with C (version C++ 4.5) is\r\nused to calculate the drift....
Environmental considerations have called for new developments in building\r\ntechnologies to bridge the gap between this need for lower impacts on the environment and\r\never increasing comfort. These developments were generally directed at the reduction of\r\nthe energy consumption during operations. While this was indeed a mandatory first step,\r\ncomplete environmental life cycle analysis raises new questions. For instance, for a typical\r\nlow thermal energy consumption building, the embodied energy of construction materials\r\nnow becomes an important component of the environmental footprint. In addition, the\r\nusual practice in life cycle analysis now appears to call for some adaptationââ?¬â?due to\r\nvariable parameters in timeââ?¬â?to be implemented successfully in building analysis. These\r\nissues bring new challenges to reach the goal of integrated design, construction,\r\ncommissioning, operation, maintenance, and decommissioning of sustainable buildings....
