Measuring office efficiency: look beyond occupancy rates

A full office feels like success. The parking lot is packed, the coffee machine is working overtime, and Tuesday afternoons are buzzing with activity. But attendance is a means to an end, not a result. The question that really matters is not how many desks are occupied, but whether the workplace demonstrably improves collaboration, well-being, space utilization, and team performance. Only then can you measure the true return on your office investment.

Why Office Occupancy Is a Misleading Measure of Success

Market data shows a clear trend. JLL reports global office utilization of 56% in 2026, compared with 54% in 2025 and 49% in 2024. CBRE recorded average building utilization of 53% in 2025, based on client portfolios covering approximately 28 million m². Interestingly, these figures differ, partly because of variations in data sources and definitions. This alone demonstrates why occupancy figures should be interpreted with caution.

More importantly, increased attendance does not prove that performance is improving. In a randomized study involving 1,612 employees, working from home two days a week reduced employee turnover from 7.2% to 4.8%, a reduction of one-third, without any measurable impact on performance reviews, promotions, or work output. A full office is therefore no guarantee of value creation. It measures who is present, not what is being achieved.

Define Your Denominator First

One of the most common mistakes is comparing apples with oranges. Occupancy, attendance, and utilization are not defined consistently across organizations. For every metric, clearly specify the numerator and denominator. For example:

  • Average number of people present divided by total capacity
  • Workstations in use divided by available workstations
  • Occupied hours divided by bookable hours

Only compare market figures when the numerator, denominator, measurement period, and target population are consistent. Measure peak utilization separately from averages. A reasonable weekly average can hide overcrowded Tuesdays and almost empty Fridays. That difference determines whether employees can find a suitable workspace or end up wandering around in frustration.

A Balanced Scorecard Built Around Four Pillars

Instead of focusing on a single number, use a scorecard that measures four key outcomes. Select two to four metrics for each pillar and document their definitions, data sources, owners, and measurement frequency.

Collaboration

Do not measure collaboration simply by counting meeting hours. Instead, measure whether the right people are present at the same time for a specific purpose. Which activities genuinely benefit from physical presence? Examples include complex decision-making, coaching, creative sessions, and relationship building. According to CBRE, 68% of employees identify collaborating with colleagues as their main reason for coming into the office. Gallup also reports that teams with a formal hybrid collaboration plan are 66% more likely to be engaged than teams without one.

Well-Being

Pay attention to autonomy, workload, employee engagement, psychological safety, and acoustic and thermal comfort. The figures highlight why this matters. In the Dutch National Working Conditions Survey (NEA) 2025, 20.7% of employees reported burnout symptoms, rising to 25% in the ICT sector. Nationwide, 43% experience low levels of autonomy. Employee absenteeism reached 5.6% in the fourth quarter of 2025. Among employees who reported sick, 23% attributed their absence partly to work-related factors. Well-being is not merely a soft metric; it has a direct financial impact.

Space Utilization

Connect average and peak utilization to different types of spaces, missed reservations, availability issues, cost per occupied workstation, and actual energy consumption. This is where a common conflict emerges: 89% of Leesman respondents consider individual focus work important, while 70% of corporate real estate leaders identify collaboration as the primary purpose of the office. This tension calls for a carefully designed mix of spaces for focused work, meetings, and social interaction, rather than simply adding another open-plan area.

Team Performance

Focus on actual outcomes rather than digital activity. Measure turnaround times, quality, customer results, predictability of project delivery, and employee retention. The number of messages sent, mouse movements, or hours spent in the office are not reliable indicators of performance. In 2024, the Leesman workplace experience score was 69.5 for offices compared with 79.5 for working from home. Increasing office attendance alone will not automatically close that experience gap.

Turning Measurement Into a Management Tool

Make the workplace a strategic management tool rather than treating it solely as a real estate issue. This starts with a clear approach:

  1. Develop a hypothesis for each team and establish a baseline measurement.
  2. Create a single overview of the key metrics across all four pillars.
  3. Define responsibilities in advance. Use aggregated, anonymized data and involve HR, IT, facilities management, and the works council.
  4. Combine three data sources: objective utilization data, short employee experience surveys, and existing business performance indicators.
  5. Test the approach through a representative pilot that includes both peak and off-peak days.
  6. Make decisions based on the overall results and scale up only when space efficiency improves without compromising focus, well-being, or quality.

Pay Attention to Privacy and Employee Representation

Access badges, Wi-Fi data, and sensors can quickly become tools for employee monitoring. In the Netherlands, prior approval from the works council is required for systems capable of monitoring employee attendance, behavior, or performance, even if those monitoring capabilities are not yet being used. Always choose the least intrusive method and comply with the principles of the General Data Protection Regulation (GDPR). Trust is essential for collecting meaningful and reliable data.

Correlation Does Not Equal Causation

Remain critical of your own conclusions. Satisfied teams may visit the office more frequently and perform better, but that does not necessarily mean one causes the other. Self-reported data can also be biased. The NEA reports a self-reported absenteeism rate of 4.84%, compared with 5.4% according to employer records. Furthermore, there is no universal benchmark. A workplace with laboratories requires different performance indicators from a consulting firm or software company.

A successful office is therefore not the fullest office, but the one that demonstrably contributes to business objectives. By bringing strategy, data, design, and implementation together within a single measurement framework, organizations can prevent improvements in occupancy from coming at the expense of focus, well-being, and performance. The result is greater clarity, direction, and control, and a workplace that truly works.
