The Mashrabiya Window

A mashrabiya is a projecting oriel window enclosed with carved wood latticework. Traditional across the Islamic world.

Occupants look out without being seen. The wooden screen provides essential privacy.

Jars of water inside cause evaporative cooling. Smaller bottom and larger top openings control air current speed.

A Danish cartographer observed latticed windows for ventilation and light.

Earliest evidence dates to 12th century Baghdad. Sustainable architecture interest spurred modern revival. Medieval HVAC still passing inspection.

Latticework designs differ by region. Common patterns include hexagonal, kanaysi, maymoni, and cross.

The Louvre Abu Dhabi dome was inspired by traditional mashrabiya. Architects use these for thermal control today.
