The fact that building HVAC controls are so often owned and locked down to people outside the building is infuriating. I worked on a community theater production that rented space from a high school in the summer. It was perfectly cool throughout rehearsals, but sweltering hot when we came in on Saturday because the HVAC system's schedule hadn't been overridden to reflect being occupied over the weekend. The thermostats around the building (less than 5 years old, with very powerful AC) were, of course, placebos. We called the district-level administrator who had control of HVAC, but she was out of town and couldn't get her VPN client to work. So no AC for us.
