2. Attic fan - Wikipedia

   en.wikipedia.org/wiki/Attic_fan

   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. Wind-powered roof turbines, often colloquially referred to as "whirly-birds", are also used to ventilate attics and other confined ...

3. 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.

4. Wind turbine - Wikipedia

   en.wikipedia.org/wiki/Wind_turbine

   When a turbine is mounted on a rooftop the building generally redirects wind over the roof and this can double the wind speed at the turbine. If the height of a rooftop mounted turbine tower is approximately 50% of the building height it is near the optimum for maximum wind energy and minimum wind turbulence.

5. Unconventional wind turbines - Wikipedia

   en.wikipedia.org/wiki/Unconventional_wind_turbines

   Counter-rotating wind turbines Light pole wind turbine. Unconventional wind turbines are those that differ significantly from the most common types in use.. As of 2024, the most common type of wind turbine is the three-bladed upwind horizontal-axis wind turbine (HAWT), where the turbine rotor is at the front of the nacelle and facing the wind upstream of its supporting turbine tower.

   Photovoltaic panels, small wind turbine or electricity from a 'green' supplier; Natural materials — avoidance of PVCu and other plastics; Rainwater harvesting; Grey-water collection; Composting toilet; Glass that has two or three layers with a vacuum in between to prevent heat loss (double or triple-glazed windows) Solar panels or wind turbines

7. Stack effect - Wikipedia

   en.wikipedia.org/wiki/Stack_effect

   Some buildings are designed with strategically placed openings at different heights to induce the stack effect where cool air enters through low-level windows or vents, and warm air escapes through higher-level openings like skylights, roof vents, or clerestory windows.
