To ask the Secretary of State for Education, if he will make it his policy to issue an update of the Building Bulletin 101:'Guidelines on ventilation, thermal comfort and indoor air quality in schools for (a) BS EN ISO 16890:2016, (b) BS EN ISO 10121-2:2013 and (c) BS EN 16798-3:2017.

The design and construction standards for new school buildings are under regular review to reflect any changes in regulations or best practice nationally. There are no plans at present to update Building Bulletin 101 'Guidelines on ventilation, thermal comfort and indoor air quality in schools' which was published in 2019.

We published guidance on 3 June on the reopening of buildings and campuses to help providers make informed decisions about their provision in ways that protect the health and well-being of both staff and students. Our guidance contains links to other sources of relevant advice, including on safer workplaces: https://www.gov.uk/guidance/working-safely-during-coronavirus-covid-19, which includes references to the importance of ventilation, particularly in advance of reopening buildings.
