Step 02. The comparison report
Every realistic alternative, modeled side by side.
The assessment measured what your light is costing you. The report turns that data into a decision: each lighting alternative scored in the same units, on the same horizon, so the specification you defend is the one the numbers chose.
What gets compared
Four axes, one honest comparison
A lighting decision usually fails because the options were never priced in the same currency. The report scores every alternative on the same four axes, so a cheaper scheme can’t win by ignoring what it doesn’t deliver.
Capital cost
What each scheme costs to install, complete (fixtures, controls, and commissioning), so no alternative wins by hiding a line item.
Circadian correction
How far each scheme closes the measured gap between the light your building delivers today and the exposure the standards call for, hour by hour.
Operational savings
The recurring return: workforce health costs avoided and energy the new scheme does not use, modeled over the same ten-year horizon for every option.
Human outcome
What the correction is worth where it shows up (sleep, stability, incidents, and performance), translated into the financial format your board reads.
Inside the report
- Every realistic alternative for your building, modeled side by side
- Economic cost of the current light environment
- Capital cost against operational savings, on a common horizon
- Impact on human outcomes, staff performance, and institutional risk
- The recommended scheme, and the numbers that chose it
- Formatted for board and procurement review
Why timing matters
The economic case has to exist before the specification is written, not after it has already been challenged. Bring the report into the budget conversation while the design is still open, and good lighting enters it with numbers behind it.
The recommended scheme doesn’t stay on paper: it runs for a week in one real area of your building next. How the pilot works →
Let the numbers choose the specification.
A comparison your board can read, and a recommendation you can defend in procurement.
