2. Passive ventilation - Wikipedia

   en.wikipedia.org/wiki/Passive_ventilation

   The ventilation system of a regular earthship Dogtrot houses are designed to maximise natural ventilation. A roof turbine ventilator, colloquially known as a 'Whirly Bird' is an application of wind driven ventilation. Passive ventilation is the process of supplying air to and removing air from an indoor space without using mechanical systems.

3. Attic fan - Wikipedia

   en.wikipedia.org/wiki/Attic_fan

   Wind-powered roof turbine ventilator. Mechanical attic ventilation fans may be powered in a variety of different ways. Most attic ventilators fitted to homes are powered off mains electricity. A trend towards solar-powered attic ventilators is observable in the interest of conserving electricity and lowering monthly utility bills.

5. Ventilation (architecture) - Wikipedia

   en.wikipedia.org/wiki/Ventilation_(architecture)

   Poor ventilation in rooms is identified to significantly increase the localized moldy smell in specific places of the room including room corners. [11] There are three types of natural ventilation occurring in buildings: wind-driven ventilation, pressure-driven flows, and stack ventilation. [15]

6. Windcatcher - Wikipedia

   en.wikipedia.org/wiki/Windcatcher

   In the center, a shuksheika (roof lantern vent), used to shade the qa'a below while allowing hot air rise out of it. [16] The windcatcher can function in two ways: directing airflow using the pressure of wind blowing into the windcatcher, or directing airflow using buoyancy forces from temperature gradients (stack effect).

7. Fan (machine) - Wikipedia

   en.wikipedia.org/wiki/Fan_(machine)

   Electric fans used for ventilation may be powered by solar panels instead of mains current. This is an attractive option because once the capital costs of the solar panel have been covered, the resulting electricity is free. If ventilation needs are greatest during sunny weather, a solar-powered fan can be suitable.
