In an environment where the carbon footprint is becoming increasingly large, we need to start developing sustainable solutions which can keep greenhouse gases at bay. It is estimated that the building industry contributes to almost 40% of all of Australia’s greenhouse gas emissions! To put this into perspective, this consists to a whopping 90 megatons of emissions that are emitted annually in constructing new buildings and maintaining the infrastructure of pre-developed ones. It is time for us to take action! At EcoMENA, we believe in creating a sustainable future so that the building industry can thrive and support our future … Continue reading →

Beating the Texas Heat: The Role of Weatherization in Enhancing Solar Panel Performance

Texas is known for its scorching summers and intense heatwaves, making it a challenging environment for solar panel performance. However, with the right weatherization techniques, you can maximize the efficiency and longevity of Metro Express solar panels even in the face of extreme temperatures. How Heat Impacts Solar Panel Performance One of the key factors that affect solar panel performance in hot climates is heat. When solar panels get too hot, their efficiency decreases, which can lead to a drop in power output. This is known as the “temperature coefficient,” which measures how much the panel’s efficiency decreases as the … Continue reading →

Introduction to Solar Pond

A solar pond is a three-dimensional, open-air pit, filled with water endowed with special properties. It receives solar energy through insulation, then the trapped heat is extracted from it from the water lying at the bottom of the pond. When solar energy falls onto the pond, it heats the water, splitting it into three sections: the first section is the uppermost layer, or Surface Zone, containing fresh water with a low level of salinity. This owes to the fact that salts gather at the bottom. The second layer is the middle layer, called the insulating layer or Insulation Zone, whose … Continue reading →

Blue Roads in Doha: An Innovative Way to Combat Rising Temperatures

The streets of Abdullah Bin Jassim near the iconic Souq Waqif in Doha were painted blue recently as part of a pilot project to reduce the effects of extreme heat in the city. By reflecting the heat instead of absorbing it, the blue-coated asphalt roads will support Qatar’s battle to combat the Urban Heat Island effect (UHI). Image Source: The Peninsula (2019) Blue road project to bring temperature down What is UHI? With 55 per cent of the world’s population currently living in urban areas, cities struggle to meet their overflowing capacity resulting in a dense network of high-rise buildings, … 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 →
