How businesses are using booking data to reduce office footprintcosts

For years, businesses designed offices around one fairly simple assumption: one employee needed one desk. However, hybrid working has fundamentally changed that equation.

Employees may now spend two or three days a week in the office, different teams come in on different days, and the purpose of the workplace itself has shifted. Yet many organisations are still paying for office space based on assumptions established when almost everybody attended five days a week.

The opportunity isn't simply to reduce the size of the office. It's to understand what space a business actually needs—and what its unused space is really costing.

Increasingly, the answer can be found in workplace booking data.

The value isn't the booking; it's the data.

When organisations first introduce desk and room booking technology, the objective is usually operational: employees need an easy way to find and reserve somewhere to work.

But every booking creates data.

Over time, that builds a picture of how an office is being used: which days employees attend, which floors and areas are popular, which desks are rarely selected, what size meeting rooms are most frequently required, where demand exceeds capacity, and where expensive space regularly sits empty.

That information can turn a relatively simple workplace tool into something much more strategically valuable.

Rather than asking employees how much office space they think they need, businesses can start looking at how they actually use it.

The cost of an empty desk isn't zero

When we talk about underutilised offices, it's easy to focus purely on rent. But the financial impact is much wider.

An unused desk still occupies valuable floor space. Depending on how the workplace is configured, it can also have monitors, docking stations, desk-booking technology, and other equipment consuming energy. The organisation is still paying for lighting, heating, cleaning, maintenance, business rates, and facilities management across the wider space.

There is also a less obvious cost: people's time.

If an employee arrives at a busy office and spends ten minutes looking for somewhere suitable to work, or walks between meeting rooms trying to find one that's actually available, that friction has a cost too.

It's one of the reasons we developed ClearVC's Workplace Efficiency Calculator. It allows organisations to enter employee numbers, desks, meeting rooms, and average workplace utilisation to start estimating the potential impact of underused space, wasted energy, and lost employee time.

The purpose isn't to produce an exact figure that automatically tells a business how many desks to remove. It's to encourage a much broader conversation about what workplace inefficiency actually costs.

Don't design an office around the average

The danger is looking at a utilisation percentage and immediately deciding that the office can be reduced by the same amount.

Real workplaces don't operate on averages.

An office could appear significantly underutilised across a five-day week while approaching capacity every Tuesday, Wednesday, and Thursday.

Reduce the estate based solely on average occupancy and you could save money on paper while creating a terrible employee experience in reality.

The more valuable insight is in the patterns.

Businesses need to understand peak demand, differences between teams, seasonal changes, and the types of spaces employees choose when they're in the building.

The objective should be right-sizing, not simply downsizing.

For some organisations, that might mean reducing an entire floor or consolidating multiple locations. For others, the data might show that they don't actually need less space—they need different space.

Perhaps there are too many individual desks and not enough collaboration areas. Perhaps six-person meeting rooms are regularly occupied by two people while smaller rooms are constantly unavailable.

That's where booking data starts informing workplace design rather than simply administering it.

A booking isn't necessarily a person

There is another important distinction: booking data represents intent, not necessarily occupancy.

Someone can reserve a desk for Thursday and then decide to work from home. A recurring meeting can continue reserving a room even when nobody attends.

Organisations, therefore, need to understand the difference between booked and actually used.

Check-ins, automatic release of unused bookings, and occupancy technology can help create a more accurate picture.

This is particularly important if the data is going to inform a significant property decision. Reducing a property footprint based on inaccurate booking information could prove considerably more expensive than the space the organisation was trying to save.

Use the data before the lease event

Another mistake is waiting until a lease renewal, relocation, or refurbishment is imminent before asking how the workplace is being used.

By then, there may not be enough historical information to identify meaningful patterns.

If a lease event is 12 or 18 months away, that's an opportunity.

Start collecting and analysing workplace data now. Look at peak days, no-shows, room utilisation, desk demand, and differences between teams.

And don't leave the conversation solely to Facilities.

HR understands employee behaviour and working patterns. IT understands the technology. Facilities understands how the building operates. Finance and property teams understand the commercial implications.

Put that information together and suddenly a decision about the next office isn't based on somebody walking around on a quiet Friday afternoon and deciding the building looks empty.

It's based on evidence.

Smaller shouldn't mean worse

Ultimately, the goal shouldn't be to squeeze the greatest possible number of people into the smallest possible building.

If organisations want employees to spend meaningful time in the office, there needs to be a reason to make the journey.

The opportunity created by booking data is therefore not simply less office space; it can be a better office.

If data demonstrates that part of an estate is genuinely unnecessary, reducing that footprint can create savings. But some of those savings can then be redirected towards the spaces employees actually value: better collaboration environments, improved meeting technology, focus spaces, acoustics, and workplaces designed around different types of work.

That's the conversation I think businesses should be having.

Not: How many desks can we remove?

But: When are our people coming in? Why are they coming in? What spaces are they actually using? What is unused space costing us? And what does all of that tell us about the workplace we need next?

The smartest office isn't necessarily the biggest or the smallest.

It's the one that's the right size—and the right shape—for how people actually work.
