Dossier Inrichting kantoorwerkplek – Guidelines for Dutch Office Workspace Design
The Dossier Inrichting kantoorwerkplek is an authoritative reference document published by Arbokennisnet. It serves as a regulatory guide for the design and arrangement of office environments in the Netherlands. The current version, revised in March 2024, provides a structured framework based on the Arbowet (Working Conditions Act), the Arbobesluit (Working Conditions Decree), and the Besluit bouwwerken leefomgeving (Bbl). It addresses the legal obligations of employers and the rights of employees regarding health, safety, and ergonomic standards in professional office settings.
The document's scope encompasses a wide range of regulatory domains, including physical ergonomics, mental workload, indoor climate, and fire safety. It details requirements for traditional cell offices, flexible office concepts, and hybrid working arrangements. Specific attention is given to established standards such as NEN 1824 for spatial requirements, NEN 2449 for desk dimensions, and ISO 9241 for display screen work. It further defines critical thresholds for ventilation, lighting levels, and acoustic comfort to mitigate risks such as RSI/KANS (Complaints of the Arm, Neck, and Shoulder) and Sick Building Syndrome.
This dossier functions as a compliance manual for facility managers, architects, and occupational health professionals. It categorizes office risks into physical, psychological, and environmental factors, providing concrete mitigation strategies and technical values for building and interior planning.
Legislative Framework and Compliance
The regulatory basis for office design is rooted in Dutch national legislation. Employers are mandated to organize work and provide equipment that prevents risks to health and safety, as outlined in Article 3 of the Arbowet.
- Arbobesluit Article 1.43: Defines location-independent work (thuiswerken) and the employer's duty of care for remote environments.
- Arbobesluit Article 5.8: Specifies that work involving a display screen for more than two hours per 24-hour period must meet ergonomic requirements.
- Besluit bouwwerken leefomgeving (Bbl): Sets minimum requirements for fire safety, ventilation, and emergency exits in office buildings.
- Article 11 Tabakswet: Enforces a total smoking ban within business premises.
Spatial Requirements and NEN 1824 Standards
The document utilizes NEN 1824 to define the minimum floor area required for various office elements. These measurements, performed according to NEN 2580:1997, ensure sufficient movement space and access.
- Standard Workstation: Minimum 4 m² per employee, including desk, chair, and circulation space.
- Equipment space: An additional 1 m² is required for a desk with a flat screen.
- Storage and Reading: 1 m² for a storage cabinet and 1 m² for a reading or writing surface.
- Meeting Facilities: Minimum 2 m² per person for dedicated meeting areas.
Ergonomics and Furniture Specifications
Furniture must be adjustable to accommodate the physical dimensions of the workforce, following guidelines like NPR 1813 for office chairs and NEN 2449 for workstations.
- Adjustable Desks: Surface height must be adjustable between 62 cm and 82 cm.
- Fixed Height Desks: Must be set at 74-76 cm, potentially requiring footrests for certain users.
- Leg Room: A minimum free space of 60 cm width and 65 cm depth must be maintained under the desk.
- Sit-Stand Desks: Under NEN 2441, these must adjust between 62 cm and 128 cm with a minimum speed of 25 mm per second.
Indoor Climate and Physical Properties
The quality of the indoor environment is determined by specific values for air, light, and sound, categorized into classes A+, A, B, and C.
- Ventilation: A minimum of 1.3 dm³/s per m² of fresh air must be supplied to ensure air quality.
- Lighting: Workspace surfaces require a minimum of 500 lux for display screen work, with a Color Rendering Index (CRI) of 80 or higher.
- Acoustics: Maximum noise levels for high-concentration work are set at 35 dB(A) per NVN 3438.
- Temperature Control: Solar shading is required to prevent excessive heat and reflections on screens.
