Hybrid Work Occupancy Patterns — What the Data Actually Shows
Post-COVID hybrid work has permanently reshaped commercial real estate utilization. We analyzed occupancy patterns from 2024–2026 across APAC portfolios, revealing that average utilization sits between 30–60%, with volatile mid-week peaks and…
Wi-Fi vs. PIR vs. CO₂ — Occupancy Sensor Accuracy Comparison for HVAC Optimization
Not all occupancy sensors are created equal. We evaluated Wi-Fi counting, passive infrared (PIR), CO₂, and camera-based AI across four buildings over 18 months.
