Why desk occupancy sensors matter for CRE

Desk occupancy sensors detect whether a workstation or desk is in use and provide objective utilization data that enables better portfolio decisions.

Right-sizing real estate and reducing vacancy costs.
Designing efficient hot-desking and flexible workplace strategies.
Improving cleaning schedules and facility services based on real use.
Linking occupancy to HVAC and lighting controls to save energy.
Measuring recovery and safety compliance after events (e.g., phased returns).

Define: Occupancy sensor — a device that detects presence or absence at a desk or in a zone. CRE — commercial real estate, the industry managing office portfolios and tenant spaces.

Sensor types and when to use them

Choose a sensor type based on accuracy needs, privacy concerns, budget, and integration requirements.

Passive Infrared (PIR)

Detects motion and heat changes.
Pros: low cost, low power use, simple installation.
Cons: limited to detecting movement — may miss seated stationary users.
Use for general zone-level presence and energy control.

Ultrasonic

Uses sound waves to detect motion.
Pros: detects smaller movements, works in enclosed areas.
Cons: can be sensitive to noise and reflections.
Use for medium-sensitivity desk or zone detection.

Pressure mats / desk sensors

Detect weight or pressure on a chair or desk.
Pros: reliable for seat occupancy, simple signals.
Cons: physical installation needed; may trigger false positives (bags, items).
Use for individual desk-level accuracy.

Camera-based analytics (computer vision)

Uses video to infer occupancy and headcounts.
Pros: high accuracy, rich analytics (flow, density).
Cons: strongest privacy concerns, higher cost, requires processing power.
Use for open-plan analytics where privacy is addressed and consent obtained.

Bluetooth/Wi‑Fi and badge-based sensing

Uses device or badge proximity to infer presence.
Pros: non-intrusive, leverages existing infrastructure.
Cons: requires employee device or badge, less accurate for exact desk presence.
Use for hot-desking ecosystems tied to booking systems.

CO2 and environmental proxies

Indirect method estimating presence from air quality changes.
Pros: useful for zone-level ventilation control.
Cons: not reliable for individual desks.
Use to optimize HVAC rather than desk counts.

Data, privacy, and regulatory considerations in the UAE

UAE CRE managers must treat occupancy data as potentially personal or sensitive depending on granularity and follow clear principles to remain compliant and reduce risk.

Understand applicable laws: The UAE Personal Data Protection Law (PDPL) and local free zone regulations (e.g., DIFC, ADGM) set rules for processing personal data. Camera feeds and individually identifiable logs are most sensitive.
Minimize data collection: Collect only the data necessary for defined goals (e.g., utilization percentages rather than named user logs).
Anonymize and aggregate: Use aggregation and anonymization to remove identifiers before storage or sharing.
Obtain lawful basis and consent: Where data can be linked to individuals (badge logs, cameras), obtain consent or ensure another lawful basis such as contractual necessity.
Transparency: Publish clear notices to occupants about what is collected, purpose, retention, and contacts for data requests.
Retention and deletion: Define short retention periods for raw data; keep only aggregated metrics needed for analysis.
Security controls: Encrypt data in transit and at rest, apply access controls, and maintain firmware update practices.

When using camera-based sensors, implement strong privacy-by-design controls such as edge-processing (no raw video stored), masking, and face-blurring to reduce privacy risk.

Integration with workplace systems

Sensors deliver value when integrated into operational systems to inform workflows and automate responses.

Workplace booking and desk hoteling platforms: Real-time occupancy can feed booking systems to reduce no-shows and inform dynamic allocation.
CAFM/BMS (Computer-Aided Facility Management / Building Management System): Link occupancy to optimize cleaning, maintenance, HVAC, and lighting schedules.
Analytics dashboards: Combine sensor data with HR and meeting systems to analyze utilization and inform portfolio decisions.
Access control: Badge data can augment occupancy insights but treat it carefully due to privacy.

Integration priorities

Open APIs and standard protocols (MQTT, REST) for flexibility.
Data normalization: ensure occupancy metrics are consistent across floors and buildings.
Real-time alerts: for safety, overcrowding thresholds, and cleaning needs.

Deployment planning and best practices

Follow a phased approach and pilot before large-scale rollout to validate accuracy, acceptance, and integration.

Pilot phase

Select representative floors and desk types.
Test multiple sensor types to validate accuracy and user acceptance.
Run pilots for several weeks to capture weekly patterns.

Site survey and mapping

Create a floorplan map with desk locations and install points.
Note power access, mounting heights, and potential obstructions.

Installation best practices

Mount sensors to minimize occlusion and interference.
For desk-level sensors, choose chair-mounted or under-desk placements thoughtfully (avoid trip hazards and aesthetic issues).
Consider battery vs mains: battery sensors simplify wiring but require maintenance cycles.

Calibration and tuning

Calibrate sensitivity to reduce false positives/negatives.
Re-test after furniture changes or layout reconfigurations.

Maintenance and lifecycle

Plan battery replacement schedules and firmware updates.
Monitor sensor health and connectivity through automated alerts.

Change management

Communicate benefits to employees clearly and address privacy concerns.
Provide opt-out mechanisms when feasible and disclose policies.

Vendor selection criteria

When evaluating vendors, prioritize accuracy, privacy, integration, local support, and security.

Accuracy and validation: Request real-world accuracy studies and pilot results.
Privacy features: Edge-processing, anonymization, and configurable retention.
Integration capabilities: APIs, connectors to CAFM/BMS, and analytics tools.
Local support and presence: UAE-based support or regional partners for faster service.
Scalability and cost model: Upfront hardware, per-device fees, cloud costs, and maintenance.
Security and compliance: Certifications, encryption standards, and secure OTA updates.
SLAs and warranty: Installation support, uptime guarantees, and replacement policies.

Include contractual clauses that address data ownership, portability, and termination handling.

KPIs and analytics to track

Measure actionable metrics that support portfolio and operational decisions.

Desk utilization rate: percentage of desks occupied over defined periods.
Peak occupancy and peak times: identify busiest hours/days.
Average dwell time: how long a desk remains occupied in a session.
Turnover rate: frequency of desk changeovers.
No-show rate (for booked desks): proportion of booked desks not used.
Energy alignment: correlation between occupancy and HVAC/lighting energy use.

Use these KPIs to inform right-sizing, optimize cleaning schedules, and redesign floor layouts for efficiency.

Sample deployment timeline (high level)

Week 0–2: Define objectives, compliance review, vendor RFP.
Week 3–6: Pilot selection, site survey, pilot installation.
Week 7–10: Pilot evaluation, stakeholder feedback, privacy audit.
Week 11–20: Rollout planning, full installation in phases.
Month 6+: Optimization, analytics development, policy refinement.

Adjust cadence for portfolio size and complexity.

Quick checklist for UAE CRE managers

Define clear business objectives for occupancy sensing.
Choose sensor types based on required accuracy and privacy sensitivity.
Conduct PDPL and local regulatory review; document lawful basis.
Run a pilot on representative spaces before full deployment.
Integrate sensors with CAFM, booking, and BMS systems.
Implement data minimization, aggregation, and retention policies.
Plan maintenance, firmware updates, and battery replacement cycles.
Include vendor SLAs, support, and data ownership clauses in contracts.
Communicate transparently with occupants; provide contact and opt-out mechanisms.

Final recommendations

Start small, measure, and scale. Prioritize privacy and integration early to maximize adoption and ROI. Use occupancy data not just to reduce space but to improve employee experience, energy efficiency, and operational agility.

Engage legal, IT, and facilities stakeholders in planning to ensure compliance with UAE regulations and to align the technology with business objectives. For CRE leaders participating in campaigns like Butlr CRE 4December Campaign or working with regional partners such as Carrefouruae, collecting standardized, privacy-preserving occupancy metrics will make your portfolio decisions more defensible and actionable.
