A good design works with human nature, not against it. If you want people to adjust to the elevator's ideal behavior, you have to subtly guide them to the right direction -- which is possible, but the way you asked it sounds along the lines of telling a whole office to start following arbitrary elevator efficiency rules. That aside, I think Jandy was referring to a different scenario than what you're envisioning. If you have a skyscraper, and a trendy new bar opens on the 36th floor when the 36th floor use to be occupied by an office, but the elevator was programmed to rest at the 36th floor only at 9AM, lunch hours, and 5PM, telling the bar they have to make their clientele come and leave at those hours for "efficiency" will not go over well. Instead, having an elevator that notices no one's calling from the 36th floor before 8PM anymore doesn't sound like a bad idea.
