What is adequate ventilation?

The proposed Building Regulations update, designed to tackle the pandemic and beyond, state that the new standard for ventilation is 10-15 litres per second per person1.

The proposed regulations also state that “buildings should have the ability to provide adequate outdoor air to all occupied spaces without recirculating air within spaces or between different spaces, rooms or zones, unless the ventilation system has an ultraviolet filter, HEPA filter or other germicidal filter.”1

Other guidance points towards a minimum or equivalent of 6 Air Changes per Hour of clean air.

Our GUV devices exceed these clean air standards, typically providing 10-20 equivalent air changes per hour.
