Energy Efficiency in Cleanrooms and Separative Devices: ISO 14644-16, Outreach Article
Richard Gibbons

The ISO 14644 family of cleanroom standards has been at the center of international cleanroom standards development for many years and covers most facets of cleanroom activity and cleanroom types from large ballroom cleanrooms to isolators and clean tunnels. The series is under constant review and is still expanding. ISO 14644-16 is a new standard added to the cleanroom series and the first to focus on energy efficiency.

The new standard was proposed and convened by the UK as a progression of their 2013 cleanroom energy management document, BS 8568 .  It reinforces the principal established in that guide, that airflow preparation and circulation are the main contributors to cleanroom energy use, demanding up to 80% of total energy in some facilities. While much of its original advice in BS 8568 on basics such as over-engineering, leak prevention, filter selection, management and maintenance is retained in the new standard, the content is expanded and airflow volume assessments replace air change rate calculations.
