Check Meeting-Room Utilisation Against Your Ceiling — Free
A meeting-room calendar counts bookings, rarely the hours the room is even open. Divide the booked hours by the open hours for each room and hold the busiest room against the ceiling you plan to.
The proof surface
Meeting-cost tools price what an hour in the room costs. This reads the demand side instead: how much of each room’s open time is actually booked, and which room is running past your planning ceiling.
Why the flat version breaks
Counting hours a room is merely unlocked
Open hours are bookable hours; a room that cannot be booked before nine is not open at seven.
Averaging rooms together
A full boardroom and an empty training room average to a comfortable middle figure that tells nobody anything.
Treating utilisation as a performance score
Utilisation is demand information for room planning; it is not a verdict on the people who book or avoid the room.
How to work the meeting-room utilisation register
One row per bookable room — the focus room, the boardroom, the training room — not one row per meeting.
Add every reservation that occupies the room, including recurring holds and internal blocks. A clash where two bookings overlap counts once.
Use the hours the room is genuinely bookable — a room in a building open forty hours a week offers forty, not one hundred sixty-eight.
The register holds the highest utilisation. A room booked past its own open hours means a clash or an over-long hold is hiding somewhere in the calendar.
What the meeting-room utilisation register replaces
| Question | Before | Visible working |
|---|---|---|
| Counting hours a room is merely unlocked | Open hours are bookable hours; a room that cannot be booked before nine is not open at seven. | Count booked hours in the period |
| Averaging rooms together | A full boardroom and an empty training room average to a comfortable middle figure that tells nobody anything. | Set the open hours per room |
| Treating utilisation as a performance score | Utilisation is demand information for room planning; it is not a verdict on the people who book or avoid the room. | Watch the busiest room, not the average |

FIRST-LOAD
Input is processed locally and a draft is saved automatically in this browser profile when storage is available. Reset to sample clears that draft; Pro history has its own clear button. A state link encodes your inputs in its URL: share only non-sensitive rows. Browser history, clipboard and anyone receiving the link may retain it. Optional AI use below leaves this device; it is not required.
Utilisation arithmetic on the hours you supply. Not room-booking software, facilities management or a workplace policy ruling; confirm open hours and booking rules with whoever runs the space before changing reservations.
Data note: Everything runs in this browser tab on the meeting-room utilisation register: your room | booked hours | open hours in the period stays on this device, nothing is uploaded, and the reading is rebuilt only when you press run.
Go deeper: the companion app files the same reading as a bound register page
The article demo above runs without limits. The companion app keeps a local history, exports the rows as CSV, prints the meeting-room utilisation register reading, and holds your drafts on this device — one free run, then $ 4 one-time for the layer that keeps filing.
The meeting-room utilisation register reading is complete for free. The optional $4 layer adds print, row CSV and the last five local reading summaries; it does not add hidden answers. Checkout is not configured yet; the article demo remains unlimited.

What this is built on
- Method: Use the hours the room is genuinely bookable — a room in a building open forty hours a week offers forty, not one hundred sixty-eight.
- All sample records are invented examples. The app does not fetch measurements, policies, files or personal records.
- Google’s official pricing page, fetched 2026-09-29, lists free-tier access including AI Studio. Optional formatting only; limits and availability can change. Free-tier content may be used to improve products. Never paste private records there.
Before: Open hours are bookable hours; a room that cannot be booked before nine is not open at seven. After: the meeting-room utilisation register shows the working beside each named row so the reader can change the assumption and inspect the consequence.
Optional AI formatting, not calculation
For this meeting-room utilisation register, use the free AI Studio interface only if available to you, with no paid API key. Manual entry completes the same workflow for free. Supply only fictional or non-sensitive notes. Review its output against the source; never paste unresolved questions into the numeric rows.
Format my non-sensitive notes for a meeting-room utilisation register. Return plain rows only: room | booked hours | open hours in the period. Preserve supplied quantities exactly. Do not guess missing values; list questions separately. Do not calculate or add advice. I will check every row before pasting into the local tool.
Accepted schema: room | booked hours | open hours in the period. No AI response is executed as code.
