Lab occupancy spikes crank up ventilation and hood costs. Ventilation alone can eat up 45% of your lab’s energy use. That’s huge. If you track lab occupancy in real time, you can cut air flow when it’s not needed. Bills drop. Safety stays strong. Ventilation is about 45% of energy use in life science labs and 60% in chemistry labs. It’s the biggest target for savings.
Meanwhile, benches and instrument rooms often sit empty while other teams hunt for space. It's wasted energy and wasted space. That double hit costs you money.
Real-time occupancy data flips that. Cut ventilation to safe minimums for empty rooms. Spot underused benches. Reclaim wasted space. Stay compliant with every safety rule. Plug in Occuspace Macro sensors and start getting live data in minutes - no batteries or ceiling drilling needed.
When you know exactly how many people are in your lab, you can match ventilation to real needs. HVAC systems account for 60-70% of lab energy use. That’s double what commercial buildings use. Track lab occupancy live, cut air changes when labs are empty, and crank them back up when people show up.
Fume hoods are big energy users, too. A standard fume hood burns about $1,900 per year if the sash is left up. Close the sash at night and you can save $1,000 per hood annually. But to do that, you need to know when it’s open versus just sitting there all night.
Bench use works the same way. Track how long people spend at tissue culture benches, instrument stations, and write-up spots. You’ll right-size your space. Underused rooms become new labs. You free up capital and resources.
Adjusting air flow starts with safety. EH&S teams set minimum air-change rates based on each room's risks. Those numbers aren’t flexible. You must always hit the safe range. But don’t overdo it when the lab is empty. Real-time data lets you do just that.
Air changes per hour (ACH) measures how often air gets replaced. NFPA 45 recommends at least 4 ACH for empty labs, over 8 for those in use. Some labs use control bands: “A” labs run 8 ACH occupied, 6 ACH empty. “B” labs go 6 ACH occupied, 4 ACH empty.
When sensors say the room is empty, your automation system drops to the low setpoint. As soon as someone walks in, it goes to the higher, occupied rate. Direct, safe, and efficient.
Time-in-target means your lab stays in the right air flow band. If your setpoint is 8 ACH and the system is in the 7.5-8.5 range 95% of the time, you’re good. If it dips to 6 at busy times, fix the gap.
With live occupancy and air flow data, you see when you’re off target. Tweak controls, rebalance dampers, or add capacity before you’re flagged in an audit.
Sash hours track how long hoods stay open. Open sashes need big exhaust, which means higher energy bills. One CFM of air costs about $3.90 a year, and a single hood can pull lots of CFM.
Pair sash position with occupancy data. You’ll know which hoods get left open at night or weekends. Use auto-reminders or interlocks to fix it. VAV systems that adjust air based on sash save $1,500-$3,000 per hood every year when paired with low-flow tech.
Accurate occupancy sensing takes the right signals. You need:
Combine these signals in one platform for the full picture.
Modern occupancy sensors use mmWave radar, thermal arrays, or PIR to count, not watch. The best ones get up to 99% accuracy by combining radar and PIR. They track movement, not identity, so privacy stays protected.
Fume hood telemetry - sash position, airflow - shows real use. Door contacts and pressure sensors keep containment in check. IAQ monitors watch CO₂, temp, and humidity. Gas detectors spot leaks in process labs.
Match bookings to real bench time. Do you have ghost reservations? Fix them. With all this data, you allocate space with confidence and respect everyone’s privacy.
Once you’re tracking lab occupancy, it's time to act. When sensors spot an empty lab, the automation system drops vent rates. As soon as someone walks in, everything ramps up. Demand control tied to occupancy can save about $0.50/ft²/year.
See diversity with fume hoods. If you’ve got ten, but only three get used at a time, you can downsize fans and air handling. Sensors on hoods adjust air flow instantly. Only condition what you need.
Chemical and standby areas must stay at baseline. But write-up zones and offices? Let start/stop algorithms pre-cool before people arrive and coast after they leave. Less run time. Same comfort.
Always remember: safety comes first. Live occupancy lets you run at the efficient edge - never beyond.
For every bench and room, capture dwell times. Check bookings against real use. Find:
Adjust spaces based on the data. Tissue culture labs see short, frequent use. Instrument rooms get longer sessions. Write-up areas fill up during analysis time and clear out during experiments. Track these patterns to right-size every bench and room.
If a room runs at 30% average utilization and never hits 50% at peak, consider consolidating it. If another’s always 90% full, add more space or tighten scheduling.
Compare bookings and true presence. Find ghost allocations. Reassign those benches to teams who actually use them. Split big spaces into focused instrument bays plus flexible work zones based on real-day demand.
This is how smart offices maximize space. Occupancy data lets you adjust supply to real-world needs. The same goes for labs. Measure use. Adjust inventory.
Researchers need to trust the system. Cameras feel too intrusive. Personal tracking breaks that trust. That’s why camera-free detection matters.
No identities - just "five people in Lab 301" or "65% bench use this week." Never "Jane was at bench 12." Use camera-free sensors like mmWave or thermal. Aggregate to zones, not people.
When people know their privacy is protected, they get on board. No fuss.
Your platform needs to work for every user group:
Use an "inside now" view. Instantly see which labs are open, full, or have spare capacity.
Break out metrics by room type - tissue, instrument, write-up. Spot trends and tackle outliers. Dwell times reveal queue patterns for better planning.
Your fume hood panel shows sash hours, exhaust flow, and fan power at a glance. Overnight sash opens jump out. Overlay comfort data for a complete picture - if CO₂ or temp spikes, adjust airflow right away.
A quality panel checks sensor coverage, data uptime, and entry/exit counts. If entry and exit numbers don’t add up, fix sensor coverage fast.
Things get even better when you plug occupancy data into your building automation system. Sensors and hoods feed the BAS, which manages airflow, lighting, and temperature within safe limits. Occuspace sensors run with HPE Aruba anchors for instant setup and tidy data.
For offices and lounges, link lights and air to people. Empty room? Systems dial down. Visitors come in? Ramps up. It's fast, efficient, and leaves containment untouched.
Always show energy per used hour. Did HVAC energy drop 20%, but occupancy fell 10%? The real efficiency gain is lower. Normalize to get the real picture.
Scaling across sites is simple. Use a clean hierarchy: site → building → floor → suite → room. Roll up weekly demand for each building. Mix in doorway counts, room sensors, hood data, and booking logs for a complete overview. You'll spot best practices, compare buildings, and repeat your wins.
Start with these:
Check comfort at peaks - how often does CO₂ cross 1,000 ppm or temp spike? Monitor queue time at shared gear. Long lines mean not enough capacity. Short stays may show underuse. Meet monthly to review trends and target your efforts.
AI reviews bench times, bookings, and hood use. It can suggest consolidating labs or automating sash reminders. You always get final say, but AI spots patterns you might miss. Safety and workflow come first. You review, then act.
Dwell and arrival data shows how teams move between lab, write-up, and shared spaces. One group may hit instrument rooms at 7 AM; another peaks at 2 PM. Write-up rooms fill during analysis, empty during bench work. See these trends and schedule smarter, all without personal tracking.
Thermal arrays count people as heat blobs - no faces or features. They deliver solid accuracy and excellent privacy. Most labs pick camera-free for trust. Today’s mmWave and thermal sensors give 95-99% accuracy at the room level - plenty for managing ventilation and space.
Live lab occupancy unlocks savings, smarter layouts, and strong safety. Adjust ventilation for real presence. Reclaim wasted space. View clear ROI in your KPIs.
A privacy-first platform plugs right into your setup. Occuspace sensors install in minutes, deliver data in hours, and work with your BAS out of the box. No extra effort. Full privacy.
