ISO 28802:2012

Overview

ISO 28802:2012 - "Ergonomics of the physical environment - Assessment of environments by means of an environmental survey involving physical measurements of the environment and subjective responses of people" - defines a general method for conducting environmental surveys to assess occupant comfort and well‑being. It applies to indoor, outdoor and vehicle environments and integrates physical measurements (e.g., temperature, sound level, illuminance, air quality) with subjective responses from occupants to evaluate overall environmental quality.

Key topics and technical requirements

• Survey design principles
  • Define clear aims, target population and sampling strategy.
  • Determine where, when and how many measurements and responses are needed.
• Measurement of the physical environment
  • Use instrumentation selected to relevant specifications (range, accuracy, sensitivity).
  • Follow calibration and handling best practices to avoid measurement artefacts.
• Subjective response methods
  • Use validated subjective scales (sensation, comfort, preference, acceptance, tolerance) to quantify occupant responses.
  • Be aware that scale presentation, translation and cultural factors affect results. (ISO 10551 offers guidance on scale construction.)
• Component‑based assessments
  • Thermal, acoustical, visual/lighting, air quality and vibration environments - each with guidance on physical measures, subjective measures and observation checklists.
• Observation and behavioural data
  • Combine instrument readings and occupant reports with observer assessments and behavioural indicators.
• Scope and limitations
  • Provides general principles, not prescriptive design solutions or new subjective‑scale construction; survey outcomes may identify issues that require specialist advice.

Practical applications and users

ISO 28802 is practical for:

• Ergonomists and human factors specialists conducting comfort assessments.
• Facility managers, building consultants and architects evaluating indoor environmental quality.
• Occupational hygienists and safety professionals assessing workplace thermal, noise or air quality issues.
• Transport designers assessing vehicle cabin comfort.
• Researchers and standards developers integrating physical and subjective data for policy, design guidance or indexed environmental metrics.

Typical uses: environmental comfort surveys, pre/post‑occupancy evaluations, workplace risk assessments, design validation for HVAC/lighting/noise mitigation, and baseline studies for occupant satisfaction.
