Every figure on this page is computed from the inputs entered, by the method stated below it. HardFM publishes no space standard, no square feet per person that any body recommends, no attendance rate and no insurance requirement: the desk ratio, the area per desk, the circulation allowance, the attendance and what a contractor must hold are your organisation's own figures and rules.
The figures above start from a worked example (60). Change any input and the answer updates as you type.

This is a space utilization worksheet that works what the floor is actually used at once attendance rather than headcount is counted. Average attendance over desks is the average utilization; peak attendance over desks is the peak; peak attendance is the desks the busiest day needs and desks less peak is the surplus; net area over average attendance is the square feet per person actually in; and peak over headcount, times ten, is the sharing ratio the attendance supports. Every figure is yours, from the door, the wifi or the bookings; the worksheet publishes no target rate. Free, on the page, no account; the paid plan keeps the counts week by week.
Average and peak, the two numbers that disagree
140 desks, 84 in on an average day and 126 on the busiest: 60% average utilization and 90% at peak. A floor that reads half empty on average is nearly full on its busiest day, and the busiest day is the one that decides whether a floor can go.
Desks needed, desks spare
The busiest day needs 126 desks, so 14 of the 140 are spare. That is the honest surplus: the desks that could be released without anyone standing on the busiest day, at this attendance pattern and before any policy changes it.
The sharing ratio the attendance supports
126 people at peak from 180 assigned is 7 desks per 10 people. That ratio, fed into the office space per person worksheet, is what turns a measured attendance into a space requirement, and the return to office policy template is what tests it against the days the policy will require.
Space utilization worksheet: common questions
How is space utilization calculated?
People in over desks available, as a percentage, on the average day and on the busiest day. On the worked example, 84 in on average over 140 desks is 60% and 126 on the busiest day is 90%. The worksheet uses your own counts and publishes no target.
Where does the attendance figure come from?
From whatever your building already counts: the door or badge reader, the wifi associations, the desk bookings, or a manual count for a month. The worksheet takes the average and the peak as two numbers; HardFM Pro keeps them week by week so the trend is measured.
Is this a space utilization software with sensors?
No. Sensors, badge readers and booking systems produce the counts; this worksheet works what the counts mean and HardFM Pro keeps them against the floor. It integrates with nothing and asserts no count of its own.
