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

نظم تقييم المباني الخضراء في الشرق الأوسط

الأبنية الخضراء لا تساهم فقط في بيئة أفضل وطرق بناء مستدامه، ولكنها تجلب ايضا الكثير من المنافع والفوائد لمالكي المباني ومستخدميها. فتكلفة الانشاء أقل، وتكلفة التشغيل أقل، وسبل الراحه أكثر، والبيئة الداخلية أكثر صحة، والعمر الأفتراضي أطول وتكاليف الصيانة أقل في المبنى الأخضر. توجد العديد من النظم لتقدير وتقييم المباني الخضراء حول العالم، مثل LEED  و BREEAM . فالاستدامة الان تعد هامة جدا في منطقة الشرق الأوسط ودول مثل قطر والامارات لديهم انظمتهم الخاصة بهم لتقييم المباني لتشمل السمات الاجتماعية والبيئية والاقتصادية والثقافية في العمارة الحديثة نظام تقييم الاستدامة الشامل (قطر) ان نظام تقييم الاستدامة الشامل (GSAS) المعروف رسميا باسم … Continue reading

Greener Built Environment in Middle East

The key drivers for greener built environment in the Middle East are economic in nature. Green and energy-efficient buildings are getting traction in the region due to increasing energy prices and the need for energy efficient and affordable energy solutions and practices within the construction sector. Large real estate developers find in this a new marketing and PR tool that contributes to their bottom line and to demonstrating their commitment to sustainable development goals and environmental responsibility. From the supply side, suppliers and service providers find new business opportunities in this market transformation and this has become a driver for … 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

Tips to Improve Indoor Air Quality

Indoor air pollution is considered as one of the top environmental risks to public health worldwide due to increasing number of building-related illnesses. Studies have found that concentration of indoor pollutants is significantly higher indoors than they are in outdoor environment, which is two to five times and sometimes hundred times higher than outdoor levels. As most of the people spend 80% to 90% of their lives indoor, indoor air quality has significant implication on sustainability. Decreased indoor air quality can affect quality of life of the building occupant, increase health risks and increase the liability for building owner, decrease … Continue reading

District Cooling Perspectives for the Middle East

District cooling produces chilled water in a centralized location for distribution to buildings like offices and factories through a network of insulated underground pipes. The chilled water travels to different buildings, where the water circulates through refrigeration coils or uses absorption technology to enter the air-conditioning system. During winter, the source for the cooling can often be sea water, so it is a cheaper resource than using electricity to run compressors for cooling. What is District Cooling District cooling provides effective control over internal temperature of a building, requires less maintenance than a standalone air-conditioning system, consumes lesser space and … Continue reading

Green Roofs in MENA – Prospects and Challenges

Green roofs are emerging technologies that can provide a wide range of benefits to communities interested in enhancement and protection of their environment. The major benefits of green roofs are reducing energy use as well as air pollution and greenhouse gas emissions, enhancing stormwater management and water quality, decreasing heat island effect by regulating temperature for the roof and the surrounding areas and providing aesthetic value and habitats for many species.   According to a 2013 MENA renewable energy status report, the Total Primary Energy Supply (TPES) in Middle East and North Africa has reached about 800 million tons of oil.  This … Continue reading

Top Green Building Trends Worldwide

With green building movement sweeping across the world, innovative technologies are being developed to keep pace with increasing shift towards sustainability. Integration of biodegradable, recycled, recyclable and renewable materials in the construction of buildings is attracting great attention worldwide. Natural paints, recycled steel, cellular concrete, clay bricks, wood, bamboo etc. are getting huge popularity in construction of green buildings. Another interesting innovation is zero-energy building which utilizes solar cells/panels, wind micro-turbines, fuel cells and biofuels, among others, to meet electricity and HVAC requirements of the building. Likewise, net-zero-water-use buildings make use of water conservation systems to efficiently manage water consumption, … Continue reading

Green Building Trends in the Middle East

The Middle East region faces a unique set of environmental and socio-economic challenges in the form of water scarcity, harsh climatic conditions, ecological degradation and abundance of fossil fuels. Commercial and residential buildings in the Middle East consume more energy than those in other parts of the world, mainly on account of extremely hot weather, rampant use of glass exteriors and heavy reliance on air-conditioning. The Middle East building industry, in recent years, is actively trying to make widespread use of eco-friendly architecture, traditional building methods and sustainable construction practices. Some of the other drivers for the progress of green buildings sector … Continue reading

Trends in Sustainable Housing

There has been large-scale proliferation in construction of buildings worldwide due to population growth, economic development, urbanization and migration. According to UN Habitat, there has been a migration of the world’s population from rural areas to cities or smaller urban areas. In fact, this trend is expected to continue and cities within the developed as well as developing nations are expected to grow in terms of population. As a result all forms of construction activities are expected to become more intense than ever in the years to come. Usually the development of urban areas suffers from weak process of planning … Continue reading
