  "title": "Change workspace variables by domain so you can learn what helped",
  "summary": "A full makeover can improve the room and destroy the explanation.",
  "kind": "protocol",
  "body": "Use the four IEQ domains to stage changes. Fix the most obvious high-friction or safety issue first, then change one major domain at a time when practical: thermal, air, acoustic or visual. Keep notes on comfort and work function. This matters because the 2025 IEQ review shows high heterogeneity and context dependence.",
  "limits": [
    "Some building problems require combined changes or professional work; learning value does not outrank safety."

    {
      "claim": "The 2025 IEQ systematic review found very high heterogeneity across productivity relationships, supporting context-specific rather than one-number workspace optimization.",

    "You simultaneously buy a lamp, purifier, fan, headphones and new productivity software."

    "Some building problems require combined changes or professional work; learning value does not outrank safety."

  "example": "Resolve direct glare first, then evaluate whether a purifier or acoustic treatment still solves a real remaining problem.",
  "check": "You retain enough causal visibility to know which environmental change earned its place.",
  "steps": [
    "Rank the current environmental problems by severity and plausibility.",
    "Fix safety issues immediately.",
    "Change one non-urgent major domain.",
    "Observe comfort and task performance for several comparable sessions.",
    "Keep or revert before adding the next expensive change."
