Assessment of Adequacy of Ventilation

• Every living room should be provided with at least two windows with at least one of these opening directly on to an open space. If this is not the case, advise the family to use an exhaust fan.
• Measure the height and breadth of the windows and the doors.
• Calculate the area of each one by the formula: area = length × breadth.
• Total window area should be 1/5th of the floor area.
• The total area of the doors and the windows taken together should be 2/5th of the floor area.
