Features of a Green Building

A green building incorporates environmental considerations into every stage of the building construction and focuses on the design, construction, operation and maintenance phases. The key process difference between green and conventional buildings is the concept of integration, whereby a multi-disciplinary team of building professionals work together from the pre-design phase through post-occupancy to optimize the building for environmental sustainability, performance, and cost saving. Green buildings offer widespread benefits to a number of building industry stakeholders, including building occupants and society as a whole. Green buildings typically incorporate superior air quality, abundant natural light, access to views and noise control which benefits … Continue reading

World Habitat Day 2017: Affordable Homes

World Habitat Day, observed every year on the first Monday of October, is meant to reflect on the state of our urban areas and the basic human right regarding provision of adequate shelter to all human beings. World Habitat Day (WHD) also aims to remind the planners and government officials of the collective responsibility for the habitat of future generations and a day to encourage grassroots action from civil society organizations to advocate for universal decent housing. Each year, World Habitat Day takes on a new theme chosen by the United Nations based on current issues relevant to the Habitat … Continue reading

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 … Continue reading

Bioremediation: Fighting Pollution with Bacterial Assistance

Bioremediation is an engineering process which uses microorganisms to degrade a material. It can be used to treat contaminated media such as water, air and soil, by altering the environmental conditions to stimulate growth of microorganisms and degrade the target pollutant and enhance the quality of the media. In this age of rapid industrialization and depleting natural resources, there is an alarming need for a much effective sustainable development model and new ways to decontaminate and re-energize our surrounding land, water and air. Bioremediation provides an efficient and environment-friendly treatment compared to various other remediation technologies involving chemicals and radiation. … Continue reading

Waste Prevention in Middle East – Prospects and Challenges

The best way of dealing with waste, both economically and environmentally, is to avoid creating it in the first place. People and businesses that use resources wisely not only save money but also have much less impact on the environment. That is why waste prevention rightly occupies the top spot in the so-called “Waste Hierarchy” set out in EU and national waste legislation.  Waste prevention is about the way in which the products and services we all rely on are designed, made, bought and sold, used, consumed and disposed of. For example: Making products that are more durable, repairable, re-usable … Continue reading

Countries Driving Solar Surge in MENA

The countries of the Middle East and North Africa (MENA) are known for their abundance of fossil fuels, yet they also have another energy resource at their fingertips – solar power. Some countries such as Saudi Arabia, which have great solar resources, are transitioning to utility scale solar energy production.  This allows them to export more of their fossil fuel instead of using it to produce power domestically. However, the decision to switch to solar power isn’t just to preserve oil resources for export. The countries in the MENA region are also experiencing increased demand for electricity due to rising … Continue reading

Renewable Energy in GCC: Need for a Holistic Approach

The importance of renewable energy sources in the energy portfolio of any country is well known, especially in the context of energy security and impacts on climate change. The growing quest for renewable energy and energy efficiency in the Gulf Cooperation Council (GCC) countries has been seen by many as both – a compulsion to complement the rising energy demand, and as an economic strength that helps them in carrying forward the clean energy initiatives from technology development to large scale deployment of projects from Abu Dhabi to Riyadh. Current Scenario The promotion of renewable energy (RE) is becoming an … Continue reading

Desalination Outlook for MENA

Desalination is a water treatment process that separates salts from saline water to produce potable water. The desalination process uses large amount of energy to produce pure water from salt water source. Salt water is fed into the process, and the result is an output stream of pure water and another stream of waster with high salt concentration. Desalination techniques are mainly classified into two types: Processes based on physical change in the state of the water, and Processes using a membrane that employ the concept of filtration. There are more than 15,000 industrial-scale desalination units worldwide, with combined capacity exceeding … Continue reading

Energy Efficiency Perspectives for MENA

MENA countries are facing an increasing challenge in reducing greenhouse gas emissions from the energy sector. Qatar, Kuwait, UAE, Bahrain and Saudi Arabia figure among the world’s top-10 per capita carbon emitters. In case of business-as-usual scenario, GHGs emissions from the energy sector will continue to rise throughout the region. According to a recent report by International Energy Agency (IEA), energy intensity demand in MENA is mainly driven by population and economic growth and reliance of heavy industries on generous energy subsidy. It is projected that primary energy demand in the region will be doubled by 2030 and the region’s … Continue reading

Food Security Strategy in Qatar

Qatar is a water-scarce and arid region which has its own share of demographic and socio-economic problems. The cultivation of food crops is a difficult proposition for Qatar due to scarcity of water supply and limited availability of arable land. The country is vulnerable to fluctuations in international commodity markets because of heavy dependence on imported grains and food items. The increasing dependence on foreign food imports is leading to a growing sense of food insecurity in Qatar. Understanding Food Security Food security is the condition in which all people at all times have a physical and economic access to … Continue reading

Understanding Carbon Footprint

With rising awareness of global warming and effects of emissions on the environment, corporates and individuals alike are rising to tackle environmental issues. Carbon footprinting, the first step to reduce carbon emissions, is the total set of greenhouse gas emissions caused directly or indirectly by an individual, organization, event or product. The main reason for calculating a carbon footprint is to inform decisions on how to reduce the climate change impact of a company, service or product. Carbon footprints are measured by undertaking a greenhouse gas assessment. Once the size of a carbon footprint is known, a strategy can be … Continue reading

Algae Biorefinery – Promise and Potential

High oil prices, competing demands between foods and other biofuel sources, and the world food crisis, have ignited interest in algaculture (farming of algae) for making vegetable oil, biodiesel, bioethanol, biogasoline, biomethanol, biobutanol and other biofuels. Algae can be efficienctly grown on land that is not suitable for agriculture and hold huge potential to provide a non-food, high-yield source of biodiesel, ethanol and hydrogen fuels.  Several recent studies have pointed out that biofuel from microalgae has the potential to become a renewable, cost-effective alternative for fossil fuel with reduced impact on the environment and the world supply of staple foods, such as wheat, maize and sugar. What are Algae? Algae … Continue reading
