Passive design strategy?

Hi all.
I would like to know how designer positions occupants as a key determinant to achieve the intended performance of passive design, especially in the tropical climate.

For instance, a simple example would be how do we encourage people to use the window or any other opening devices other than air-conditioning unit in a public building?

Thanks.

Passive design is about smart thinking.

If you wanted people to use windows instead of air conditioning, there are 3 very simple methods.
1, fit each air conditioned work area with a coin operated bow, so that whoever wants the conditioning on, has to pay for it directly.
2, turn off the air conditioning at the master switch.
3, do not include an air conditioning in the building design.

All 3 of the above methods would encourage people to open a window, on the principles of saving their own money or because you have not given them an option.

However, a public building is different in that the people using it, are often only passing through or there for a short period of time. And people often do not feel that they are allowed to open windows in an area in public buildings. The easiest ways here, would be to have the staff to open the windows in the first place, and allow for the public to close them, as more people would happily do this if they were cold. The other options, are to either put up signs suggesting people open windows if they need air or fit air vents into the building so that they move the air around without power. It is a very simple thing to do, by having low air vents and high air vents. As the room warms, the warm air rises, it pulls in cooler air from outside, via the lower air vents and the hot air then passes outside through the higher vents.

I hope this helps in what you ask...
