A workplace can appear busy overall, with employees regularly coming into the office, active floors, and high demand for certain meeting rooms, while still experiencing significant room utilization challenges as many other spaces remain consistently underused.
That is the problem Utilization Efficiency is designed to uncover.
As one of the four pillars of the InnerSpace Building Performance Index, Utilization Efficiency measures how effectively rooms are being used across a building. Rather than focusing on overall activity, it looks at the share of rooms that remain lightly used over time.
For the purposes of this analysis, a room is considered utilized whenever one or more people are present in the space. A room that falls below 20% utilization is a room that is rarely being used and is not attracting meaningful demand.
The pillar represents 25 points of the overall score and is built around one core metric:
- Percent of Rooms Under 20% Utilization
This metric helps answer a simple question: How much of our room inventory is failing to attract meaningful demand?
Why Building-Level Averages Are Not Enough
Building-wide averages can hide important details.
A workplace may appear healthy overall while still carrying a significant amount of unused capacity. A handful of popular rooms can make utilization look strong even when many other rooms see little activity.
Utilization Efficiency brings the analysis down to the room level. It helps leaders understand whether demand is spread across the room inventory or concentrated in only a small number of spaces.
That distinction matters because excess capacity is often hidden in the details.
The Metric Behind Utilization Efficiency
Utilization Efficiency is based on the percentage of rooms that average 20% utilization or less during the reporting period.
The 20% threshold is designed to identify rooms that are not attracting meaningful demand. It is not about one slow day or week. Instead, it highlights rooms that remain consistently underused over time.
In practical terms, a room below 20% utilization is a room that is rarely being touched relative to the time it is available. The fewer rooms that fall below the threshold, the stronger the score. As more rooms remain underutilized, the score declines. The goal is not to maximize utilization in every room. It is to identify whether too much of the room inventory is sitting below a meaningful level of demand.
Room Mix and Excess Capacity
The real value of Utilization Efficiency is understanding the relationship between room supply and actual demand. When many rooms fall below the utilization threshold, it may indicate excess capacity. It may also suggest that the room mix is not aligned with how employees work.
For example, a workplace may have too many large conference rooms and not enough smaller meeting spaces. Certain rooms may be poorly located, outdated, or no longer suited to current work patterns. This is why Utilization Efficiency is more than a measure of activity. It helps leaders evaluate whether their room inventory supports the workplace strategy.
Customizing the Analysis
Every workplace is different, which is why Utilization Efficiency can be customized to focus on the spaces that matter most.
Organizations can choose which room types to include, such as:
- Meeting rooms
- Conference rooms
- Collaboration rooms
- Focus rooms
- Training rooms
- Team rooms
- Project rooms
- Other selected room types
The analysis can also be filtered by building, floor, room type, business hours, core days, and reporting period. This flexibility allows leaders to answer questions such as:
- Which room types are most consistently underused?
- Are certain floors carrying excess capacity?
- Do utilization patterns change by day of week?
- Are trends improving or worsening over time?
The result is a more actionable view of room performance.
Understanding Trends Over Time
A single reporting period can identify underused rooms. Trends reveal whether the issue is persistent. If the same rooms remain underutilized month after month, there may be a deeper mismatch between supply and demand. If utilization improves after a redesign, policy change, or workplace investment, the data can help validate that decision. This is where Utilization Efficiency becomes decision support.
The score identifies the issue. The trend helps leaders determine how to respond.
What the Score Indicates
A high Utilization Efficiency score suggests that most rooms are attracting meaningful demand and that excess capacity is limited.
A mid-range score suggests opportunities to improve room mix, room allocation, or workplace design.
A low score typically indicates a large share of rooms remain lightly used and may signal hidden excess capacity.
In these cases, leaders may consider actions such as:
- Repurposing underused rooms
- Consolidating redundant room types
- Resizing spaces to better match demand
- Rebalancing meeting, focus, and collaboration spaces
- Adjusting workplace policies
- Improving room visibility and accessibility
- Informing future design and investment decisions
The goal is not to eliminate every underused room. Some flexibility is valuable. The goal is to identify when underuse becomes significant enough to affect workplace performance, cost, or employee experience.
From Room Data to Better Decisions
At the end of the day, leaders care most about the decisions they can make with the data.
Utilization Efficiency helps identify where room inventory is aligned with demand and where it is not. It helps real estate teams understand excess capacity, workplace teams improve space allocation, and leadership teams prioritize investments based on actual behavior.
The score itself is useful, but the real value comes from the questions it helps answer:
- Which rooms are underused?
- Which room types are overbuilt?
- Where is excess capacity concentrated?
- How are utilization patterns changing over time?
- What interventions could improve performance?
These are the insights that turn utilization data into action.
The Bigger Picture
Utilization Efficiency represents 25 points of the InnerSpace Building Performance Index because room-level performance is a critical part of workplace effectiveness.
A building can appear busy while still carrying significant hidden inefficiency. By measuring the percentage of rooms under 20% utilization, Utilization Efficiency identifies spaces that consistently fail to attract meaningful demand.
Just as importantly, the analysis can be customized to reflect each organization's priorities, whether by room type, building, floor, business hours, or reporting period, resulting in a more practical view of workplace performance that reveals not only whether the building is being used, but whether the rooms within it are being utilized effectively enough to justify the space they occupy.
