1.1.3 Close windows and doors when HVAC systems are operating
Description
Make sure windows or doors are not open unnecessarily, especially when heating, cooling or air conditioning systems are operating. To ventilate the room it is sufficient to have the window open for 10 minutes. In addition, keep it opened for longer involves losing heat from the heating system or cold from the air conditioning system. Turn off the HVAC systems during that time.
Benefits
- Easy application
- Saving in heating and cooling costs could be considerable, depending on unnecessary openings
Limitations
- Occupant acceptance
Economic assessment
The cost is zero, although it is convenient to train and inform properly users on these issues.
