The government is proposing to introduce a requirement for trickle vents in all replacement windows and a new method for ensuring ventilation is not impaired as a result of energy efficiency improvements carried out on existing buildings.
The changes are in Approved Document F: Ventilation, which was published last month.
Changes to ventilation will also be introduced to improve indoor air quality and reduce the spread of airborne viruses in new non-residential buildings. This will include the mandating of CO2 monitors and additional standards for recirculating ventilation systems in all new offices.
