Workplace Utilization: What to Measure & Why

Most organizations can't answer if the space they’re paying for is being used efficiently.

‍

According to Butlr’s 2026 State of Office Space Report, a survey of 400 U.S. buildings and facilities decision makers, nearly two-thirds (62%) have no way to learn about unexpected uses of space without directly asking or observing employees. Only 19% say their space-planning decisions are based mostly on data. More than a third (36%) base those decisions more or mostly on gut instinct and experience.

‍

That uncertainty adds up. Decision makers estimate they're paying to heat or cool an average of 24% of unused or underused space in a typical week. And 99% say uncertainty about how space is used has disrupted business plans over the past five years, from delayed expansions to canceled renovations to postponed energy investments.

‍

Workplace utilization is the foundation for nearly every smart decision about your building portfolio. This article covers what utilization means, which metrics matter, how to collect the data, and what to do with the insights once you have them.

‍

What Is Workplace Utilization?

Workplace utilization measures how effectively people use physical space relative to its capacity and availability over time. It goes beyond headcount or badge swipes to reflect how full a space is, how often it's occupied, and if the types of spaces you've built match how people work.

‍

In other words, headcount only tells you how many people entered a building on a specific day. But office space utilization tells you:

• The fourth floor ran at 80% capacity while the third floor was half-empty
• Six-person huddle rooms were booked 40 times last week while two 20-person boardrooms went unused
• Your cafeteria doubles as a de facto meeting space every afternoon because there aren't enough bookable rooms

‍

Utilization vs. Occupancy

These two terms are often used interchangeably, but they measure different things and drive different decisions.

• Occupancy is a snapshot showing whether people are present
• Utilization is a trend showing how well the space performs over time

‍

For instance, you might have a conference room that's booked from 9 a.m. to 5 p.m. every day. Occupancy might look high. But if every meeting has three people in a 12-seat room, utilization is low. You're paying to light, cool, and clean a room that's running at 25% of its capacity.

‍

Enterprise teams managing large portfolios need the utilization lens beyond a simple headcount. Utilization data tells you whether that floor needs more collaboration areas or fewer individual desks, whether you're over-built for the way people work, and whether a lease renewal makes sense at the current square footage.

‍

Key Metrics to Track

Tracking occupancy rates alone isn't enough to get a comprehensive view across your portfolio. Five utilization metrics give you a more nuanced look at how space performs. These are the best practices for measuring what's working and what isn't.

‍

These metrics provide the most actionable insights when layered together, offering granular insights that no single metric can deliver on its own. A conference room with high booking rates, low peak occupancy, and short dwell times tells a very different story than one that's consistently full.

‍

How Organizations Collect Utilization Data Today

Our State of Office Space survey asked decision makers which tools they currently use to understand space usage. Most rely on methods that measure intent or entry rather than what happens inside the building.

‍

‍

The most common methods (reservations and surveys) measure what people plan to do or say they do, not what they do in practice. A conference room can be booked and never used, but most organizations don't track no-shows. Survey feedback reflects perception and memory, not behavior.

‍

Badge swipes confirm building entry but say nothing about what happens after the turnstile. Someone who badges in at 8 a.m. and leaves at 6 p.m. could have spent the entire day on one floor or moved between five of them. Without space-level data, badge systems tell you who entered but miss where they went and for how long.

‍

Nearly four in 10 organizations still rely on manual headcounts. These show a single snapshot and miss broader usage patterns. For instance, facility managers walking a floor at 10 a.m. on a Wednesday will count the morning peak, miss the afternoon lull, and have no data on Thursday at all.

‍

Even Wi-Fi and network login data, which can approximate location based on connected devices, comes with limitations. Connection data can place someone on a floor but rarely in a specific room. It also misses visitors, contractors, and anyone not on the corporate network.

‍

Over half (53%) already use sensor-based occupancy data, and that number rises to 69% among those managing building utilities. Occupancy sensors can capture accurate data on occupancy patterns in ways that badge systems and surveys can't.

‍

But collecting data isn't the same as collecting the right data or being able to act on it. Despite adoption, 79% of survey respondents say data challenges have hindered their ability to make layout changes.

‍

The Privacy Barrier

Privacy is the primary obstacle for many enterprise organizations looking to collect utilization data.

‍

In fact, 92% of decision makers view privacy as a barrier to getting utilization data. For 63%, it's a moderate to major barrier. 

‍

Larger companies feel this more acutely. 69% of decision makers at companies with 1,000+ employees see privacy as a moderate-to-major barrier, compared to 52% at smaller companies.

‍

The organizations with the most complex space challenges are also the most constrained by privacy concerns. Global portfolios, multi-tenant buildings, regulated industries, and companies with European works councils all face heightened scrutiny around sensor technology. The technology you choose determines whether legal, IT security, and works councils approve deployment or send it back for months of review.

‍

For organizations evaluating utilization solutions that need to clear privacy, legal, and works council review, Butlr's thermal-only sensors capture zero images and zero personal data by design. Talk with us to learn what that looks like for your portfolio.

Why Utilization Data Is More Urgent Than Ever

Most organizations know less about their space than they need to, and three forces are making that more expensive to ignore.

‍

RTO Mandates Are Exposing What Organizations Don't Know

Return-to-office (RTO) mandates are accelerating. According to the Flex Report Q3 2025, 34% of U.S. firms now require full-time office presence, up 2 points from the prior year. Among Fortune 100 companies, 29% require full-time office attendance. Altogether, 45% of Fortune 100 workers are in the office almost daily.

‍

If your company is considering an RTO mandate, it's easy to jump to the conclusion that you need more space. But the data doesn't support that reflex.

‍

The Flex Report shows that while required office days increased by 12% from early 2024 through Q3 2025, actual attendance rose by only 1-3%. Companies are mandating presence without knowing whether they have the right spaces in the right configurations.

‍

A building at 40% average utilization doesn't necessarily need more floors. Instead, it may need fewer floors with better office layouts, or a shift from assigned desks to neighborhoods at a 1.5:1 or 2:1 mobility ratio. You can't make that call without utilization data.

‍

Operational Costs Are Hiding in Plain Sight

Missing utilization data leads to waste in two areas.

‍

Cleaning

Our survey shows that 82% of cleaning schedules aren't based on occupancy data for individual spaces. Two-thirds of organizations clean all areas at the same frequency regardless of usage, and 60% cite cleaning costs as one of their top targets for savings.

‍

Empty conference rooms get the same wipe-down as high-traffic cafeterias. Restrooms on vacant floors get serviced on the same rotation as those next to a 200-person team. For a 10-building portfolio, even a 15% reduction in unnecessary cleaning runs can translate to significant annual savings in contracted labor hours.

‍

Energy

Our respondents estimate that 24% of space is heated or cooled without being used in a typical week. And 62% say energy costs are the top area where better utilization data could save money.

‍

If a floor is empty every Friday, running climate control on that floor five days a week means 20% of that floor's energy spend is wasted. Scale that across a portfolio of 50 or 100 floors, and the waste compounds fast. When HVAC systems run on building-wide schedules rather than responding to where people are, it creates invisible operating costs.

‍

Employee Retention and Productivity

The benefits of utilization data go beyond cost reduction alone. Our survey shows that 99% of decision makers expect a range of improvements from more efficient workspaces. Increased employee productivity was cited most often (59%), followed by improved employee focus (52%), greater collaboration (47%), and greater cleanliness (47%).

‍

Over three quarters (78%) of decision makers believe improved office design would improve employee retention. Among those who prioritize understanding space use, 41% think the improvement would be significant.

‍

For the office to justify the commute, it needs better collaboration spaces, social connection, and environments built for deep work.  Someone who commutes 45 minutes to sit in an open floor plan, join video calls with remote colleagues, and struggle to find a private room for focused work will likely question the value of their time. 

‍

What to Do With Utilization Data

On its own, data won't get you very far. The real value comes from data analysis and action, turning underutilized spaces into optimization opportunities.

‍

Right-Size Before Expanding

Before signing new leases or adding square footage, workplace utilization data can reveal whether existing space in your real estate portfolio is simply misconfigured. Organizations with consistent sub-50% utilization across floors have consolidation opportunities. Those with high peak-day utilization but low weekly averages may need flexible configurations instead of additional real estate.

‍

Consider a company with four floors averaging 45% utilization. The instinct might be to keep all four because Tuesdays and Wednesdays hit 80%.

‍

But combining utilization data with mobility ratios might show that three floors at a 1.5:1 desk ratio, with bookable overflow space for peak days, can serve the same workforce at lower cost. The fourth floor can become a sublease opportunity or a lease you don't renew.

‍

Automate Cleaning and Maintenance

Since so few cleaning schedules are tied to occupancy data, this is one of the most immediate opportunities. Real-time data from occupancy sensors lets cleaning crews focus on spaces that were used rather than servicing empty rooms on a fixed rotation.

‍

Instead of cleaning on a set schedule, crews respond to actual use. A conference room used three times today gets priority. One that wasn't booked or entered gets skipped until the next occupied day.

‍

For large portfolios, this approach reduces labor costs while keeping high-traffic areas cleaner. It ensures resources go where the demand is instead of being spread evenly across occupied and empty spaces alike.

‍

Optimize Energy Consumption

Connecting utilization data to building management systems (BMS) and integrated workplace management systems (IWMS) opens up opportunities for demand-based climate control and energy optimization. Instead of heating or cooling an entire floor on a set schedule, HVAC systems can respond to where people are.

‍

At the zone level, unoccupied sections of a floor can be set back to energy-saving temperatures while occupied zones stay comfortable. At the building level, floors with no scheduled occupancy can run minimal climate control.

‍

For large portfolios, even a 10-15% reduction in energy waste per building creates measurable savings when multiplied across dozens or hundreds of locations.

‍

Validate That Space Design Matches How People Work

Utilization data by space type reveals whether the shift toward collaboration zones is warranted or whether teams need more focus rooms. A 20-person boardroom consistently used by groups of four isn't a popular room. It's a misallocated space that could be split into two huddle rooms with higher combined utilization.

‍

Common areas becoming de facto meeting rooms signal that bookable rooms are always full. With that data, facilities and corporate real estate teams can redesign based on evidence instead of assumptions.

‍

Butlr's thermal sensors and API-first platform are designed to feed utilization data directly into the IWMS, BMS, and BI tools your teams already use. Let's talk about how it fits your existing stack.
