What a room's usage rate counts

Every usage rate in Offision is the same fraction: the hours a resource was booked for, over the hours it was available. The Usage rate dialog prints its own arithmetic, so the number is always checkable.

The worked example

Take a meeting room open Monday to Friday, 09:00 to 18:00, and a month with 22 working days in it.

That is the whole calculation. The rest of this page is which hours land on each line.

Which hours count as booked

Only the hours inside the resource’s own business hours — in Business hours mode. Anything booked at 20:00 counts towards nothing, because 20:00 is not on the bottom line either. Lunch and breaks work the same way: they are neither used nor available, so they drop out of both halves.

Only the part inside the period you are looking at. A booking that runs from July into January contributes its July hours to a July report and its August hours to an August one — never its whole length to both.

Overlapping time counts once. Two bookings that cover the same hour add one hour, not two, which is why a single resource can never pass 100%.

What actually happened, not what was reserved. Check in late or check out early and the room’s booked time shrinks to match within a moment or two, so the rate reflects the hours the room was really held. A booking nobody ever checked in for — a no-show — counts as nothing at all.

Which hours count as available

The resource’s own business hours across the period, with closed days and public holidays taken out. A resource with no business hours of its own falls back to the system’s standard working day, so it is still measured against office hours rather than against the clock.

For a floor or the whole estate, the bottom line is every resource’s business hours added together — including the rooms nobody booked. That is deliberate: an empty room is exactly the thing a utilisation figure should drag down.

In 24 × 7 mode the bottom line becomes every minute of the period instead, nights and weekends included. Nothing looks busy that way, which is why Business hours is the figure to quote and to compare rooms with.

What it does not count

• Whether anyone was in the room. This is booked time. Where rooms count people, the measured figures are in Check whether the room was actually full.
• Bookings on a resource that has since been deleted. The estate you are measuring is the estate that exists now.
