Thermostats in study rooms can be reset to a higher or lower temperature to use less energy at night or when not in use. Most lights can be turned off in lounges and bathrooms when the last person leaves since many of these spaces have one light fixture on at all times for safety. Keep the temperature setting on the highest comfortable setting when someone is in the room to conserve energy. Cooling an empty room is a waste of energy. In the heating season, some buildings have heating systems that are difficult to regulate.
All rooms have heat convectors that have a control valve located under the front of the unit.
The valve can be turned to open and close the heating water flow through the convector. Turn it open enough to reach a comfortable temperature in your room without having to open your window. Never place your bed across the front of the room's convector. This blocks natural air convection through your room's heating unit and will make your room cooler. Turn off room lights when you're not in.
