Heating costs and the university’s heating bills reached record levels last year. The university is determined to cut heating costs. It plans to do so by lowering the temperature in classroom buildings on workdays after 5 pm when classes end for the day, and on weekends, when there are no scheduled classes. The university management believes that this decision will not have a negative impact on students and their studies because classes will not be in session during the “cool off” period. The management considers it essential that energy- and cost-saving measures should not interfere with student activities.
