As the senior person in my building, I can assure you that there is no way to make everyone happy.
Some funny stories:
Three women in offices at the back of the building were freezing. Their thermostat was in my assistant's office...and she had a space heater, so the heat never kicked on in the back offices.
We had one conference room that we couldn't get below 84 in the summer...and we're have meetings with 20 people in there. We had engineers looking at it for weeks. Turns out the thermostat was installed directly across from a floor vent. Once we closed that vent, it could properly regulate itself.
We shoot for low 70's in the winter and mid 70's in the summer. It's been my observation that airflow is as big an issue as temperature setting. We take the blower fans off constant flow in the winter and everyone's much happier.
