The Language of Wind: 6 Traditional Ventilation Buildings
Discover how ancient cultures used smart architecture to tame the wind—and recreate their techniques at home.
Why This Matters: The Problem with Airflow Indoors
Children today spend much of their time indoors—often in sealed, climate-controlled environments. While air-conditioning has made life more comfortable, it can create stale, dry air and increased energy consumption.
How did people cool down buildings before electricity? What can we learn from their solutions?
This activity invites kids to become wind architects by exploring ancient ventilation strategies from around the world, recreating models of them using paper, cardboard, and airflow experiments. It’s science, history, culture, and engineering—all rolled into one wind-powered challenge!
Understanding Natural Ventilation: A Quick Framework
Traditional buildings used passive ventilation—smart design that uses wind and thermal pressure to move air through a space without fans or machines.
Key concepts for kids to understand:
- Wind Capture: Using towers, high windows, or openings to “catch” the breeze
- Stack Effect: Warm air rises, cool air enters from below
- Cross Ventilation: Openings on opposite walls to allow air to pass through
- Evaporative Cooling: Using water (like fountains or pools) to cool the breeze
These principles appear across global cultures—in clay houses, stone towers, nomadic tents, and desert palaces.
Core Activity: Build a Wind Tower Model Inspired by Persia (Iran)
What You’ll Make
A working paper model of a Persian-style badgir (wind catcher), designed to direct airflow into a structure.
Materials
- Stiff cardboard or corrugated paper
- Scissors and craft knife
- Glue or double-sided tape
- Ruler and pencil
- Small battery-operated fan (or your mouth!)
- Tissue paper or incense stick (for air visualization)
Step-by-Step Instructions
- Draw and Cut Panels
Create 4 equal rectangular panels (around 10cm wide, 20cm tall). These will form the vertical walls of the tower. - Add Openings
Cut arch-style windows near the top of each panel to allow wind entry from all sides. - Assemble the Tower
Tape or glue the 4 panels into a square tube. Optionally, add internal diagonal slats to redirect airflow downward. - Mount on a Base
Create a base with a central hole. Attach the tower vertically to mimic rooftop installation. - Test with Airflow
Place the fan at one opening or blow gently. Use tissue paper or incense to observe how air enters, moves through, and exits. - Discuss
Ask: What happens when you block one side? What if you raise or lower the base? How would this help in a hot desert?
Quick Swap Activity: Sneezing & Air Currents Demonstration
A simplified experiment to visualize airflow spread indoors, highlighting why building design matters in ventilation and hygiene.
Materials
- Spray bottle filled with water + food dye or glitter
- Dark paper or tray
- Mask (optional)
What To Do
Stand in front of the paper and lightly mist using the spray bottle—once with a mask, once without. Observe how “droplets” (mist) travel in the air.
Now try the same with a fan blowing from different directions. How does air move particles? What happens in enclosed vs. open spaces?
Around the World: 5 Other Wind-Wise Designs
1. Mashrabiya – Egypt
Wooden lattice screens on windows that reduce glare, channel breeze, and protect privacy.
Try This: Create a mashrabiya pattern using popsicle sticks or cardstock cut-outs.
2. Jali – India
Stone-carved ventilated screens that create shade and diffuse wind indoors, often seen in temples and palaces.
Try This: Use paper punches or craft knives to replicate a jali on thick cardstock.
3. Malqaf – Ancient Egypt
A sloped wind scoop that sits atop buildings and funnels wind into lower rooms.
Try This: Build a slanted funnel from recycled cardboard and see how it directs fan-blown air.
4. Yurt Vent Flaps – Central Asia
Nomadic tents with flaps at the top and bottom that regulate temperature and airflow.
Try This: Use felt or paper to make a mini yurt with a roof vent. Test how hot air escapes.
5. Windcatching Courtyards – Morocco
Central patios designed to collect wind and circulate it around shaded gardens or pools for natural cooling.
Try This: Design a cardboard courtyard with walls and an open roof. Use incense or smoke to test airflow patterns.

Final Reflection: What the Wind Can Teach Us
Traditional ventilation systems are more than relics of the past—they’re powerful design tools that respect nature, conserve energy, and keep us connected to the elements.
Let children reflect on how old-world wisdom can meet modern needs. Challenge them to think:
- Could we design future buildings using wind only?
- Can we cool schools and homes without turning on a switch?
The answers are already floating on the breeze.
