The SFE Technical Committee has provided detailed feedback on the proposed update to BS EN 17210: Accessibility and Usability of the Built Environment – Requirements and Recommendations, which was recently out for public consultation on the BSI Standards Development Portal (closing date: 14 October). The comments focus on enhancing accessibility and usability for external doors and windows. Key recommendations and observations made.
Operating Forces:
- Extend minimum operating force requirements to include windows as well as doors.
- Doors and windows should remain operable under expected wind pressures; designers must consider location and exposure.
Design Considerations for Doors
- Clearly define “fully automated” vs. “power-assisted” doors; fully automated doors are preferred for accessibility.
- Provide accessible doors adjacent to revolving doors (swing or sliding, manual or fully automated). Avoid folding doors on escape routes, as they are unsuitable for emergency egress.
- Consider replacing revolving doors with two curved sliding doors for improved accessibility and compliance.
Windows Usability & Safety
- Expand the standard to explicitly address windows, as their operation significantly impacts usability for individuals with limited strength or dexterity.
- Account for usability challenges with modern windows that often require two-handed operation; consider accessibility implications.
- Windows should remain operable under wind pressures, especially in high-rise buildings.
- Add safety measures to prevent hazards from individuals or objects falling out of windows.
Fire-Resisting Doors
- Review and update the definition of fire-resisting doors.
The Technical Committee has also contributed to the review of the CWCT TN 115 Fire performance of facades - Application to curtain walls, which is an important document for our industry.
