The coffee region is known for its hot days and cold nights. The design of the ventilation system of the house allows for the interior temperature to be constantly pleasant, without the use of any air conditioning or warming devices. The airflow of the farmhouse is designed with the ingenuity and simplicity of the termites.

* The Sweden scientific Bengt Warne observed the capacity of the termites to keep the temperature (26C/79F) and humidity (61%) stable within their colonies.

Air tunnels that mimic termite hills are dug into the earth to allow for efficient airflow. During the hottest parts of the day, cool and dry air flows into the building. The air flows through the tunnels constructed below the house, then cools down and condenses. As the hot air is leaving the house, fresh air moves in thanks to the vacuum that is created.

* The shower location outside of the house, prevents humidity from building up in the interior.
