How to Build a Business Case for Occupancy Sensors: Checklist Included

Why the Business Case Matters More Than the Technology

Occupancy sensors are increasingly straightforward to deploy. The harder challenge is getting budget approval. According to CBRE's 2026 Global Workplace & Occupancy Insights report, the average office is occupied at just 40–60% of its designed capacity on peak days, yet most organizations continue to pay for 100% of that space. The gap between what you're paying for and what you're using is your business case.

The goal isn't to pitch a technology. It's to quantify a problem your organization already has.

Pillar 1: Real Estate Cost Reduction

Real estate is typically the second-largest line item on a corporate balance sheet, after people. In major markets, commercial office space runs $50–$150+ per square foot annually depending on location and class.

Occupancy data lets you right-size your footprint. Common outcomes include:

• Eliminating underused floors or wings at lease renewal
• Consolidating to a smaller, higher-quality space rather than maintaining excess capacity
• Subleasing unused areas to offset costs during lease terms

How to quantify it: Pull your current cost per square foot. Estimate conservative utilization improvement (e.g., identifying 15% of space as chronically underused). Multiply the freed-up square footage by your annual cost per SF. That's your addressable savings.
‍

Pillar 2: Energy Efficiency and ESG Goals

The energy devoted to heating and cooling buildings accounts for around 35% of all energy consumption, the largest share attributable to any end use according to the U.S. Department of Energy. Heating and cooling unoccupied spaces is one of the largest sources of avoidable waste.

Demand-controlled ventilation (DCV) systems paired with occupancy data can reduce HVAC energy costs by 25% or more depending on the type of space according to Climate Works UK. For a 100,000 sq ft building spending $300,000/year on energy, that's $75,000+ in annual savings.

Beyond cost, this directly supports your organization's ESG reporting obligations. If your company has committed to Science Based Targets (SBTi) or reports under GRI Standards, operational energy reduction from smart building systems counts toward Scope 1 and Scope 2 emissions reductions.

Pillar 3: Employee Experience and Productivity

The workplace isn't just an expense, it's an employee experience investment. Gallup's State of the Global Workplace report consistently shows that employees who feel their workplace supports their needs are more engaged and productive.

Occupancy data enables:

• Desk and room booking systems that actually reflect real availability (not no-shows)
• Right-sizing meeting rooms so large spaces aren't monopolized by 2-person calls
• Identifying peak congestion times to improve space planning and reduce friction

These improvements are increasingly important for hybrid work models. When employees come into the office, a frustrating experience — no desks, no rooms, overcrowded spaces — undermines the entire purpose of the commute.
‍

Pillar 4: Data to Support Future Decisions

One-time cost savings are compelling. But the ongoing strategic value of occupancy data may be even more important. Organizations with accurate space utilization data make better decisions on:

• Lease renewals and expansions — negotiate from a position of knowledge, not assumption
• Capital expenditure planning — justify or defer renovation investments with real data
• Portfolio rationalization — for multi-site organizations, compare utilization across buildings to prioritize investment

CBRE’s 2026 Global Workplace & Occupancy Insights report makes it clear that the future of the workplace hinges on data and technology but AI integration isn’t without hurdles because as much as 55% of respondents cited data quality issues and lack of expertise as the biggest challenges.

Addressing the Privacy Objection

Privacy concerns are the most common roadblock in the approval process, and they're legitimate. The most effective way to neutralize this objection is to come prepared.

Modern occupancy sensing systems like Butlr use thermal, anonymous sensing — detecting heat signatures rather than capturing images or personally identifiable data. This approach is designed from the ground up to comply with GDPR and CCPA, and does not process biometric data.

In your business case, explicitly address:

• What data is and is not collected
• How data is stored and for how long
• Vendor compliance certifications and data processing agreements (DPAs)

Being proactive here signals to legal and HR stakeholders that privacy has already been considered and not deferred.

‍

Problem Quantification

• Pull current real estate cost per square foot (total and by location)
• Identify total leasable square footage across relevant spaces
• Gather current energy costs for target buildings
• Document any existing utilization estimates (badge data, booking rates, etc.)
• Note upcoming lease renewals where data could influence decisions

‍

Financial Modeling

• Estimate conservative utilization improvement (start with 10–15%)
• Calculate potential real estate savings (underused SF × cost/SF)
• Estimate energy savings (apply 20–30% reduction to HVAC/lighting costs)
• Build 3-year ROI model including implementation and annual costs
• Identify any ESG reporting value (carbon reductions, reporting efficiency)

‍

Technology Evaluation

• Confirm sensing technology is anonymous (no cameras, no biometrics)
• Request GDPR/CCPA compliance documentation from vendor
• Confirm integration capabilities with existing HVAC, BMS, or IWMS
• Verify data ownership and retention policies
• Assess deployment complexity and timeline

‍

Technology Evaluation

• Brief Legal/Compliance on data privacy approach
• Loop in HR on employee communication plan
• Confirm IT requirements (network, data security, API access)
• Identify executive sponsor in Facilities, Real Estate, or Operations
• Prepare one-page summary for CFO review

‍

Pilot Design (if applicable)

• Select 1–2 floors or buildings for initial deployment
• Define success metrics (utilization rate improvement, cost savings, satisfaction scores)
• Set a pilot duration (90 days is standard)
• Plan for readout and go/no-go decision process
  ‍

The Bottom Line

The business case for occupancy sensors ultimately rests on one argument: you are paying for space you don't fully use, and you can't fix what you can't measure. Sensor data makes the invisible visible and that visibility converts directly into cost savings, better decisions, and a more effective workplace.
