District Cooling in Middle East: Potential and Challenges

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 seawater, 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 reduces … Continue reading

Evaporative Cooling: Achieving Energy Conservation in Buildings

The global push toward sustainability and commitment to United Nations’ SDGs has brought innovative solutions of energy conservation in building design and operation. Evaporative cooling has emerged as an effective and environmentally-friendly method for reducing energy consumption (in comparison to HVAC system which consume approximately 40 percent of energy in buildings) while maintaining indoor comfort. Let’s explore the principles, applications, benefits, and limitations of evaporative cooling in achieving energy conservation in buildings. What is Evaporative Cooling Evaporative cooling leverages the natural process of water evaporation to lower air temperature. The principle is simple yet effective: when water evaporates, it absorbs … Continue reading

Energy Efficiency Perspectives for UAE

With Abu Dhabi alone on track to generate more than 10,000 megawatts of electricity for the first time, discussion about improving energy efficiency in the United Arab Emirates is taking on a more critical tone. Daytime energy use in the hot summer months is still experiencing rampant year-on-year growth, with peak demand this year growing by 12 per cent. Lying at the heart of these consumption levels is the need for air conditioning, which accounts for about half of total electricity demand. Business and Government Action At the commercial level, considerable steps are being taken to reduce the Emirate’s carbon … Continue reading

Water Management in the United Arab Emirates

The United Arab Emirates is among the top water-scarce countries in the world. However the country has one of the world’s highest per capita water consumption of 550 liters per day. The country is experiencing a rapid increase in population which has in turn resulted in huge demand for water. In 2009, the total water demand in UAE was estimated at 4.5 billion m3 (BCM) which was met by groundwater (72%), desalinated water (21%) and retreated water (7%). Water consumption in UAE is primarily divided among three sectors: Private households Agriculture Industries Private Household Sector This sector accounts for about … Continue reading
