Protocol
Change workspace variables by domain so you can learn what helped
A full makeover can improve the room and destroy the explanation.
When it fits
- You simultaneously buy a lamp, purifier, fan, headphones and new productivity software.
When to avoid it
- Some building problems require combined changes or professional work; learning value does not outrank safety.
Why it matters
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.
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.
An example
Resolve direct glare first, then evaluate whether a purifier or acoustic treatment still solves a real remaining problem.
Check your result
You retain enough causal visibility to know which environmental change earned its place.
Keep this limit in mind
- Some building problems require combined changes or professional work; learning value does not outrank safety.
Evidence and sources
The 2025 IEQ systematic review found very high heterogeneity across productivity relationships, supporting context-specific rather than one-number workspace optimization.
