Ventilation Louvres

Open window or switch on the air-con?

Would you like to open the window for fresh air and natural ventilation or have the air-con switch on? Why?

1. yeah your mom opens windows!
2. it the middle of winter so i would turn the heater on
3. If you are travelling less than 50mph then open window more than 50mph use the air con they tried this out on tv show mythbusters and that was the result in terms of fuel economy. You use less fuel with open window at under 50 but more with window open if you go faster than 50.
