Step 03 — The pilot
One week. One area. 70% circadian correction as the target.
A model is an argument. A pilot is evidence. Before you commit capital across a building, the scheme your comparison report favored runs for a week in one real space — measured against the baseline we took, in the same units the standards are written in.
What the week looks like
Seven days from baseline to verdict
Before day 1
Choose the area, fix the baseline
We pick one representative space — a ward, a floor, a classroom, a shift-worked zone — and set the baseline from the assessment: current melanopic EDI through the occupied day, the timing of exposure, and the quality of darkness at night.
Day 1
Install the modeled scheme
The alternative your comparison report favored goes in, tuned to the 24-hour curve the model specified rather than to a single static setpoint. Nothing about the space changes except its light.
Days 2 – 6
Run it, measure it, hold the curve
The scheme runs through real occupied days. We measure what the space actually delivers hour by hour, and correct drift — so what you judge at the end of the week is the design performing, not an installation still settling in.
Day 7
Read the result against the target
Measured correction against the baseline, area by area and hour by hour, next to what the model predicted. Where the scheme fell short, you see by how much and why — before that gap becomes a building-wide purchase.
Why it de-risks the purchase
The cheapest place to be wrong
70% circadian correction
The target for the week: closing 70% of the measured gap between your building's current circadian light exposure and the exposure the standards call for. It's a threshold you can hold a vendor to, not an impression of the room feeling brighter.
Your building, your people
Published research tells you what better light does in general. A pilot tells you what it does here — in this envelope, on these shifts, with these occupants and this daylight. That's the evidence that survives a procurement conversation.
One area, not the portfolio
The capital at risk during the pilot is a fraction of the specification it's protecting. If the scheme underperforms, you learn it in a week, in one space — the cheapest possible place to find out.
A week of evidence beats a year of argument.
Pilots run on the baseline from your assessment, so the fastest route into one is a 20-minute conversation about the building.
