Traditional methods of heating and cooling in Persian architecture include the following:
1. Windcatchers: Also known as Badgirs, windcatchers are structures that are built on the roofs of buildings to capture and direct airflow. They work on the principle of natural ventilation, bringing in cool air and expelling hot air, providing passive cooling.
2. Qanats: Qanats are underground channels that tap into groundwater sources and bring cool air into buildings. They were used to supply water and also served as a cooling system by providing cold air circulation.
3. Courtyards: Persian architecture often features courtyards surrounded by high walls. These courtyards are designed to provide shade and airflow, allowing cool air to circulate and bring relief during hot weather.
4. Vernacular materials: Traditional Persian buildings were constructed using local materials such as mud bricks, which have natural insulation properties. These materials help in regulating indoor temperature, keeping the building cool in summer and warm in winter.
5. Water features: Fountains, pools, and water channels were incorporated into Persian architecture to enhance cooling effects. The evaporation of water creates a cooling effect in the surrounding areas.
6. Shading elements: Overhanging roofs, pergolas, and wooden screens called mushrabiyas were used to shade windows and openings from direct sunlight, preventing heat gain and optimizing airflow.
7. Underground spaces: Persian architecture often includes subterranean spaces like basement rooms or underground chambers, which naturally maintain a cooler temperature compared to the outside environment.
These traditional methods aimed to create comfortable living environments in the harsh climate of the Persian region, utilizing principles of passive cooling, natural ventilation, and smart design techniques.
