Guideline on Hospital Ventilation

R3 Nordic is happy to announce publication of a new guideline on Hospital Ventilation.

The guideline is written by the group of Nordic experts from Denmark, Finland, Norway, and Sweden having decades of international experience within the field. For several years there has been a common understanding by authors of this document about the solid basis for Hospital Ventilation design that have now been published in this common guideline for the Nordic countries.

This design guide provides guidance and solid basis for design as well as for verification of the technical performance of ventilation systems. It also gives guidance for the users to assess the realization of the critical indoor parameters as well as life-cycle quality assurance of the systems performance.

This guideline outlines basic requirements for proper design of ventilation systems for hospital applications. The guideline expresses what is perceived to be best practice in the field at the point of publication. The published guideline is under continuous maintenance by R3 guidelines section to make them living documents being able to include new advancements and feedback from the field.

We would like to recognize contributors from Denmark; @Flemming Malcho, @Jan Mottlau, Finland; @Kim Hagström, @Jukka Vasara, Norway; @Kari Solem Aune and Sweden; @Bengt Ljungqvist, @Berit Reinmüller
