1.- Ventilation with solar chimney at roof (taking in account a possible use of black internal panting in the chimney to increase the solar absorption)
2.- Rotating chimney cowl or Wind Power Eolic Turbine Roof Extractor
3.- wind cowls ( is it possible take in account the change of wind direction to this device work properly opposite to the wind direction)
If it is possible, could you give me some advices about each one at moment of model them
