What is Space Utilization?
A measure of how much of an office's available space and seating is actually used over time.
Definition
Space utilization describes how intensively a workplace is used. It is usually expressed as a percentage: the number of desks, rooms or square metres in use compared with the total available, measured at a point in time or averaged over a period. A meeting room booked four hours out of an eight-hour day has 50 percent utilization, for example.
Utilization data helps organisations understand whether they have too much space, too little or the wrong mix. Because office space is one of the largest costs after salaries, even small improvements in utilization can produce significant savings.
Example
A company with 200 desks tracks attendance for eight weeks. Average desk utilization is 41 percent, with a peak of 68 percent on Wednesdays. Meeting rooms for two to four people are booked 85 percent of the time, while the large boardroom is used only 15 percent. Based on this, the company converts 40 desks and half of the boardroom into six small meeting rooms and a quiet zone.
Three months later desk utilization rises to 52 percent, small-room complaints disappear and the company postpones plans to lease an additional floor.
How it relates to an office map
The Office Map Editor shows analytics and heatmaps on the plan itself, counting desks with assigned names as occupied and adding attendance and bookings for signed-in teams. Seeing utilization on the map makes it obvious which zones are crowded and which are quiet.
Why utilization matters
Many offices were designed for a world where everyone came in five days a week. Hybrid work has left large areas empty most of the time, while specific spaces such as small meeting rooms are overbooked. Utilization data replaces assumptions with evidence and supports decisions about leases, layouts and policies.
How to measure it
There are several ways to collect utilization data, from simple to sophisticated. Each has trade-offs between cost, accuracy and privacy.
- Manual walk-through counts at set times of day
- Desk and room booking records
- Badge or access control data
- Wi-Fi connection counts
- Occupancy sensors under desks or in rooms
Interpreting the numbers
Averages can mislead. An office with 40 percent average utilization may still be full on two days a week. Always look at peak values and day-of-week patterns. Also compare utilization by space type: a surplus of desks can coexist with a shortage of meeting rooms.
A common target range for desk utilization in hybrid offices is 60 to 80 percent at peak, which leaves room for flexibility without wasting space.
Common mistakes
Organisations sometimes make big decisions on a few weeks of data, ignoring seasonal changes such as holidays. Others measure only desks and forget rooms and amenities. Privacy is another concern: employees may resist tracking that feels personal, so it is better to report aggregated data by zone rather than individuals.
Turning data into action
Use utilization findings to resize zones, convert underused areas, introduce team days or adjust booking policies. Visualise the results on the floor plan so stakeholders can see the problem instead of reading tables. Re-measure after each change to confirm it worked, and share results with employees so they understand why the office is changing.
