While some geosynthetic coastal structures have attained advanced stage in terms of applications and efficiency, others still lack well-structured design formulas and specifications on a sound scientific basis, hence continued experimental works for the better understanding of the hydraulic performance, stability and modes of failure of these structures. Coastal areas are dynamic with unique geomechanical feature such as soil instability, which in any case, may affect the overall performance of coastal defence structures constructed on soft soil or weak foundation.

Experimental results demonstrate that partial substitution of bitumen with waste plastic results up to 16% increment in strength whereas with rubber material, about 50% increment in strength was observed as compared to the conventional mix (CM).

Climate change and the global warming constitute an additional pressure. The “climate change” and its consequences are more important than other challenges in 21 century. The global temperature has risen by more than 2.5°C in recent years. Similarly, a global temperature rise of more than 2.5°C increases the absolute number of people at risk of hunger by 80 million. Recent estimates indicate that 25% of the world’s mammals and 12% of birds are at significant risk of global extinction. The main reason for global warming is CO<sub>2</sub> increase that is obtained from burn reaction. According to California university, CO<sub>2</sub> emissions result from emissions of: transportation 49%, electricity 30%, industrial 11%, residential 7% and commercial 3%. In the mean time, CO<sub>2</sub> concentration is 360ppm even, if severity plan will be applied as per Kyoto protocol it will arrive at 450–650ppm in 2100. Thus, there is a global resolution for declining CO<sub>2</sub> emission and one of the practical approaches is CO<sub>2</sub> decreasing in electricity sector. Each of energies has strengths and weaknesses and we focus more on nuclear energy because its CO<sub>2</sub> emission is zero. It should be added, in most of countries there is a tax for gas e.g. in the U.K. 3.4$/gallon and in Italy 2.53 $/gallon, so fossil fuel is an income for their governments but for nuclear energy government pays subsidies. Therefore it is not possible to debate about it before removing tax and subsidy. In recent years, it has been stated about tax on carbon production that it is a step forward to low carbon economy and finding the real cost of fossil fuel with attention to external costs in the environment.</p></div>","PeriodicalId":100716,"journal":{"name":"International Journal of Sustainable Built Environment","volume":"6 2","pages":"Pages 693-700"},"PeriodicalIF":0.0,"publicationDate":"2017-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/j.ijsbe.2017.07.006","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91679081","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Cement is the major manufactured material used in the production of concrete. It is an established fact that the manufacturing of one tonne of cement produces about one tonne of CO<sub>2</sub>, which is a major Green House Gas (GHG), contributing to Global Warming, Climate Change and Ozone layer depletion. In this paper, the environmental impact of cement manufacturing has been assessed on the basis of literature review. The use of Supplementary Cementitious Materials (SCMs) such as Pulverized Fly Ash (PFA) and Ground Granulated Blast Furnace Slag (GGBS), Rice Husk Ash (RHA) and Silica Fumes (SF) have been used for reducing the weight of cement in the concrete mixes to achieve, the desired compressive strength of concrete for use in construction projects. Various trial mixes have been used with partial substitution of cement with PFA and GGBFS and SF to achieve the desired high strength concrete for structural uses. The addition of the SCM has reduced the cement proportion in concrete, thereby making it relatively sustainable. The results have been assessed on the basis of reduction in the embodied energy of the concrete.

Using data obtained from detailed energy audits, several proven energy efficiency measures have been analyzed through optimized based analysis to assess their impact on the energy performance for both new and existing buildings in Qatar. Moreover, a bottom-up analysis approach is considered to quantify the multiple benefits for implementing large-scale building energy efficiency programs for the building stock in Qatar. In particular, a more stringent energy efficiency code for the new constructions and three energy retrofit levels for the existing buildings are considered in the analysis. A novel macro-economic analysis using the concept of energy productivity is used to assess the cost-benefit of large-scale energy efficiency programs in Qatar. It is determined that the implementation of a government funded large-scale energy retrofit program for the existing building stock is highly cost-effective in Qatar. In particular, it is found that a large-scale energy efficiency retrofit program of existing buildings can provide a reduction of 11,000 GWh in annual electricity consumption and 2500 MW in peak demand as well as over 5400 kilo-ton per year in carbon emissions. In addition, over 4000 jobs per year can be created when this large-scale energy retrofit program is implemented over 10-year period.</p></div>","PeriodicalId":100716,"journal":{"name":"International Journal of Sustainable Built Environment","volume":"6 2","pages":"Pages 597-609"},"PeriodicalIF":0.0,"publicationDate":"2017-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/j.ijsbe.2017.12.006","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91764253","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
