In the bustling metropolis of Dubai, where modern architecture meets extreme climate conditions, energy efficiency is a critical concern for building owners and managers. With soaring temperatures and high humidity levels, the demand for air conditioning (AC) is relentless, leading to skyrocketing energy bills. For office buildings with nearly full glass exteriors, the challenge is…
Introduction Dubai is known for its extreme heat, with temperatures often exceeding 40°C (104°F) during the summer months. For gas stations, which are typically open or semi-open spaces, keeping customers and employees comfortable is a significant challenge. Traditional air conditioning systems are often impractical due to high costs and energy consumption. This case study explores…
Outdoor cooling is a significant challenge, especially in hot climates like Dubai, UAE. High ambient temperatures, humidity, and sun radiation make it difficult to maintain comfort in open or semi-open areas. However, with the right solutions, outdoor cooling is achievable and can greatly enhance comfort and productivity. In this article, we’ll explore: What outdoor cooling…
Heat stress in dairy cattle Every summer we watched the cows suffer from heat stress and therefore it is advisable to be prepared. Heat stress in dairy cattle I. INTRODUCTION Heat stress is the result of the imbalance between the amount of energy flowing from the environment surrounding the animal and the ability to remove…
Typical data center mechanical systems usually do not use evaporative cooling , traditional air conditioning system used to cool the server room with a central chilled water plant and cooling towers. Facebook good data center design is all about efficiency and how efficiently they use energy, materials, and water, and how they tie together to…
Dewpoint During the warmer months, we can use the “Dew Point” as useful and interesting discomfort index. This particular weather element gives us an idea of how comfortable or uncomfortable we feel within the framework of hot and humid weather of the summer season. This information can be used at any time in our…
In the summer, humidity is the element that increases the feeling of embarrassment. RG Stedman (EE.UU.1979) developed the parameter windchill combined effect of heat and moisture from studies on human physiology and the heat transfer between the body, clothing and environment. When humidity is high, the wind chill value exceeds that of the air temperature.…
Wind chill As is known, the temperature of the outside air is not always a safe and reliable indicator to determine the cold that a person can feel, if exposed outdoors. There are other meteorological parameters influencing such as wind speed, radiation and humidity. The windchill term is used to describe the lower temperature that…
Temperature The temperature is a measure of the heat energy present in a substance, be it solid, liquid or gaseous.The heat, in turn, is energy that manifests as molecular vibration of a substance or as electromagnetic radiation. In simple terms we can say that heat is the phenomenon, while the temperature is a way to…
Dry bulb temperature The dry bulb temperature, or just dry temperature, air temperature measured without considering environmental factors such as radiation, humidity and air movement, which have the potential to significantly affect thermal sensation. One of the most used instruments for measuring the dry bulb temperature is the mercury thermometer, which consists of a thin…
