Introduction to Trigeneration

Trigeneration refers to the simultaneous generation of electricity and useful heating and cooling from the combustion of a biomass fuel or a solar heat collector. Conventional coal or nuclear-powered power stations convert only about 33% of their input heat to electricity. The remaining 67% emerges from the turbines as low-grade waste heat with no significant local uses so it is usually rejected to the environment. What is Trigeneration In a trigeneration system, the supply of high-temperature heat first drives a gas or steam turbine powered generator and the resulting low-temperature waste heat is then used for water or space heating. Such systems can attain higher … Continue reading

الابتكار من أجل التنمية المستدامة.. مسؤولية الجميع

على مرعقود طويلة،  اقتصر تقدم و تطور العلوم والتكنولوجيا والابتكارعلى البلدان الأكثر تقدما، حيث لا يزال الاستثمار في مجال البحث والتطوير دون الطموح في البلدان النامية. حتى مع وجود أشخاص ذوي قدرات و مواهب بارزة،  لا يزال البحث والتطوير  محصورين  في نطاق المختبرات فقط، بعيدا  عن التفاعل مع حاجات السوق والمجتمع. ولكن ليس من الممكن بأن يستمرالحال كذلك كون الإجراءات والخطوات الجماعيه المتخذة على الصعيد المحلي هي الأدوات الأساسية نحو التغيير العالمي  ولا تعمل الأهداف العالمية للتنمية المستدامة على تسليط الضوء على الابتكار كأحد الأهداف التنموية فحسب، بل تؤكد أيضا على الأهمية الكبيرة للابتكار من أجل تحقيق الأهداف الأخرى. سواء … Continue reading

Green Buildings Certification in MENA – Issues and Challenges

Green building rating systems are increasingly gaining attention in the building industry in the MENA region. During the last 15 years, there has been a regional trend in developing and applying green building ratings systems. In several countries such systems have been developed in an attempt to follow the international green movement. For example, the Pearl Building Rating System (PBRS) was founded in UAE in 2007, the Green Pyramid (GPRS) and ARZ Building Rating System in Egypt and Lebanon respectively were founded in 2008, the Edama was proposed in Jordan in 2009 and Qatar Sustainability Assessment System (QSAS) was founded in 2010.  … Continue reading

Concept of Energy Management

Energy management is the best solution for direct and immediate reduction of energy consumption. For the last few decades we have been exploring various alternatives to conventional sources of energy like solar, wind and biomass energy. However, due attention must also be given to best utilization of energy, improvement in energy efficiencies and optimum management of energy resources. Infact, energy management deals with already existing sources and actual consumption. It includes planning and operation of energy-related production and consumption units. The main objectives of energy management are resource conservation, climate protection and cost savings. The central task of energy management is to … Continue reading

Food Security in the Middle East

Despite the fact that the Middle East is blessed with a rich geological inheritance of hydrocarbons and mineral resources, it is a water-scarce and arid region that has its share of demographic and socio-economic problems. It is difficult to grow food crops in the Middle East due to scarcity of water supply and limited availability of arable land. The region is highly vulnerable to fluctuations in international commodity markets because of heavy dependence on imported grains and food items. According to a report issued in 2009 by the World Bank, the United Nations Food and Agriculture Organization (FAO) and the … Continue reading

Qatar’s Fight Against Climate Change

Qatar's environmental records have always been in news, of course for the negative ones, but it has always strived to work towards reduction of GHGs emissions. Qatar is already doing plenty to help poor countries with financing and it seems unfair to focus on per capita emissions for a country with estimated population of 2.27 million making it the 143th most populous country on earth. (For climate talks, that is heresy). This may sound harsh, especially since Qatar's contribution to global warming is tiny compared with the United States, China or India. In recent years, Qatar is making itself a benchmark … Continue reading

#InspireMENA Story 1: Humanizing Architecture – Through the Eyes of Abeer Seikaly

Through the jasmine-scented roads of L’weibdeh (Jordan) I navigated my way to Abeer Seikaly’s studio, an old house that resembles Jordan's genuine and inspiring identity. Abeer Seikaly is a young Jordanian architect who has been featured on several global and local media platforms because of her innovation "Weaving a Home" that was shortlisted for the 2012 Lexus Design Award. Influence of Education and Local Knowledge Top architecture schools in the Arab world are heavily influenced by international trends in built environment and sustainability, and unfortunately Arabic reference material is largely ignored in teaching. The emerging thinking around built environment and its relationship … Continue reading

Making a Switch to Circular Economy

All forms of wealth and security, including climate stability, biodiversity, resource availability, soil fertility, air and water purity and health, are depleted by the systemic error of running a linear economy. Linear economics consumes the basis for future growth so what is now growing fastest is unproductive activity, inactivity and instabilities. The credit crunch marks the withdrawal of faith in growth-as-usual and any reliable revival of growth and prosperity requires a switch of vision. Circular Economics The future for growth is circular economics where more economic activity would mean a faster pace of change away from waste-making and towards looking … Continue reading

الديمقراطية في المشروع الدولي البيئي

الديمقراطية القيمة والثقافة الإنسانية التي على الرغم من تنازع الرؤى والمفاهيم حول جوهر مضامينها وتوصيفاتها وضرورة وجودها ومدى شمول توافق أنماطها مع تقاليد وقيم المجتمعات الإنسانية على اختلاف ثقافاتها وانتماءاتها العرقية والدينية، وخصوصية أنظمتها الاقتصادية والاجتماعية والسياسية، تبقى المطلب الإنساني الذي صار يؤكد ضرورة وجوده في مواجهة الأزمات والكوارث الإنسانية وزحمة التراجعات في المفاهيم القيمية للعلاقات، وما يسببه ذلك من شرعنة ثقافة الجريمة وإحاطتها بحزام من التقاليد لثقافة التخلف، والتوجه بشكل متسارع لجعل ثقافة الغاب الوسيلة التي تحكم المجتمع البشري. تلك الحقيقة نتبينها في الانزلاق المتسارع نحو ثقافة الجريمة المبنية على قشور تاريخ ومبادئ ثقافات وهمية تشبه فقاعة الصابون، لكنها أحدثت … Continue reading
