Evaporative cooling
The Bidar Fort was encircled by a moat, contributing to effective evaporative cooling. Additionally, there were several smaller water bodies in front of each of the palaces, further enhancing the evaporative cooling effect.
​
Evaporative cooling is a passive cooling strategy. This process uses the principle that water absorbs heat when it evaporates, thus cooling the surrounding air.
In evaporative cooling, water is introduced into the environment through a water body or fountain. When it evaporates, it absorbs heat from the surroundings. As the water undergoes this phase change, it cools the air, creating a refreshing and cooler atmosphere. This method is particularly effective in arid or dry regions like Bidar, where the air has low humidity, allowing for optimal evaporation.
As the wind blows over the waterbody, it collects moisture, leading to an increase in humidity.
Guidelines.
1. Placement of Water Features:
Position water features like fountains, ponds, or small water bodies strategically within the design. Locate them in areas where prevailing winds can carry evaporated moisture to desired spaces, facilitating the cooling effect.
2. The karanja reservoir is quite close to the university. place and orient the buildings strategically to harness winds carrying moisture from the reservoir.
3. Natural Ventilation Channels:
Design the architecture to include natural ventilation channels that allow prevailing winds to carry evaporated moisture from water features throughout the building. This enhances the cooling effect indoors.
4. Landscaping
Plant trees and plants. Trees and plants not only provide shade but also contribute to the overall cooling effect through transpiration.
