  "body": "The 2025 IEQ systematic review organizes indoor environmental quality around air quality, thermal comfort, acoustics and visual comfort and reports highly context-dependent productivity relationships. Audit all four domains before buying another productivity app or assuming one environmental number explains everything.",

    "Productivity links are heterogeneous and individual; environmental changes should also follow building safety requirements."

  "example": "Concentration may improve more from fixing a hot noisy room than from changing the task manager.",
  "check": "At least one workspace review considers all four IEQ domains rather than one fashionable metric.",
  "checklist": [
    "Air/ventilation: stuffiness, pollutants or poor airflow.",
    "Thermal: too warm, cold or unstable for the task.",
    "Acoustic: speech, machinery or other distracting noise.",
    "Visual: glare, insufficient light or difficult contrast."
