Nowadays, architects, engineers and designers are ignoring the potential value of the most basic principles of natural cooling: Solar control (shade) Convective cooling Conductive cooling Evaporative cooling Radiant cooling In the first part of the article, solar control, convective cooling and conductive cooling were discussed in detail. When they cannot provide enough cooling then we may have to make use of evaporation. Evaporative Cooling The hottest areas tend to be dry and are ideally suited for evaporative cooling if water is available. When water is limited it can be used sparingly for just personal cooling. In general, direct evaporative cooling … Continue reading →

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 →
