The following national, regulatory guidelines have similar requirements: Section 2 of the Scottish Building Standards Agency Technical Handbooks 2007; Technical Booklet E of the Building Regulations (Northern Ireland); Technical Guidance Document B of the Government of Ireland Building Regulations 2006. AD B identifies some situations where AOVs providing natural ventilation are appropriate, including:
• Small single-stair blocks of flats
• Common escape routes in larger blocks of flats
• Basement areas
• Enclosed car parks
• Vertical smoke shafts as part of a smoke control design
