Ventilation – Window opening restrictors

Window openings in certain buildings or building areas may need to have restricted opening distances (for Healthcare buildings, in accordance with HBN 00-10 Part D: Windows and associated hardware (235) or as required by Building Control). This is generally for health and safety reasons, especially in high-rise buildings or where windows are within reach of the elderly, mentally ill or children. For BREEAM however, it is considered that such limitations can be overcome in order to provide compliant natural ventilation solutions.
