Get Wind on Your House
The house that has natural air will create perfect air quality. You need to learn layout of your house to recognize wind direction that cause fluently air circulation. Also can try with skylight that can be opened.
For example, your home environment has potential of wind from east, northeast, and southeast, then create openings such as windows, doors, jalousie, and others facing that direction. Sometimes, wind or air that comes pretty hot, to solved it you can create an intermediary with a long porch or canopy before wind come in house.
Big plants in yard can reduce heat wind. Create an opening ventilation to remove air on behind of house that cause fluently air circulation. Opened area determine it. For example garden at home picture that design by Peter Stutchbury Architecturefs
However, if your house behind was closed up buildings, hot air can be directed upwards. When it is still substandard, you can use an exhaust fan to suck air upward. See at picture: Home Ventilation Plan by Interage Mediaworks.
Maybe you can choose to build a high ceiling or plafon on 340 centimeter. Volume of space above ceiling under roof tiles are also beneficial. Home indoor with large volumes will feel colder. For example on this picture: Beautiful Home Design by Teo Nacher.(TYS)
