Quarterly environment audit at solstices/equinoxes…

When This Fires

• Four times per year at solstices (June 21, December 21) and equinoxes (March 20, September 22)
• When workspace conditions feel "off" but you can't identify what changed
• When seasonal changes have affected lighting, temperature, or sound conditions
• Complements Audit the past 12 months of calendar data — rate each… (seasonal time audit) with the environmental-specific seasonal review

Common Failure Mode

Set-and-forget environments: optimizing the workspace once and never revisiting it. The optimization was correct for June conditions but by December, daylight enters from a different angle, the room is 3°C warmer due to heating, and the sound environment changed because windows stay closed. The workspace has drifted but no audit detected it.

The Protocol

(1) At each solstice and equinox, block 30 minutes for environmental audit. (2) Measure current conditions on your key variables: light level at desk, temperature, sound level, air quality. (3) Compare against your validated baselines from Five-step environmental experiment experiments. Identify which variables have drifted. (4) For the 2-3 highest-impact variables that drifted, adjust: reposition the desk lamp for new sun angle, adjust thermostat for the new season, modify sound environment for windows-open vs. windows-closed. (5) Document the adjustments and new readings for comparison at the next audit.
