From firefighting to foresight.
Trade complaints and guesswork for clear answers. Citadel shows you every room, ranks what to fix first, holds vendors to their promises, and helps you share the results with confidence.
What changes when you can see every room
Live readings become better decisions for everyone who runs your schools, from the superintendent’s office to the boiler room.
Healthier classrooms, room by room
Our sensors can measure up to 17 parameters, including CO2, particulates, VOCs, temperature and humidity in every classroom, compared against the outdoor air at each school. Spot ventilation gaps, mold risk, virus risk, and more before they become complaints.
Spend on what works
See what your HVAC, filters and air cleaners actually deliver before you buy more. Try the least expensive fix first, and bring evidence, not guesses, to every budget decision.
Vendors held to their promises
Repairs, filter changes and equipment upgrades are checked against the readings, so results are verified, not assumed. Your district directs the work, and the data keeps every contractor accountable.
Smarter operations, less energy waste
Dispatch maintenance by data, not complaints. Live occupancy trends show where heating, cooling, ventilation and lighting run for empty rooms, so you can cut the waste.
Results your board can see
In Lawrence Berkeley National Laboratory research, better classroom ventilation was associated with fewer illness-related absences. Room-level evidence backs budget requests and grant applications, then shows how every dollar performed.
Lessons from your own buildings
Environmental science curriculum built on your schools’ indoor and outdoor data turns every building into a hands-on educational tool students can measure, question and improve.
How it works
Three steps, and the third never stops. Start with a few schools or every building you own.
Assessment
Sensors go up in every classroom, with an outdoor monitor at each school. The first weeks of readings become your room-by-room baseline, with every risk ranked.

The most health for every dollar: the right fixes in the right order, timed around your school calendar. Our advice stays independent: we don’t sell repairs or HVAC equipment.
Read more →Ongoing monitoring
The readings never stop. Alerts flag rooms that drift, every fix is verified with data, and reporting for your board, inspections and community stays current.
Read more →Built for every building you own
From century-old classrooms to new construction, every room gets the same enterprise-grade monitoring. Kaiterra Sensedge Go monitors peel and stick to the wall in under a minute: no wiring, no disruption to class, batteries that last up to 8 years, and a cellular option that keeps them off your district network.
An outdoor monitor at every school shows whether a problem started inside or came from outside, like wildfire smoke. Readings flow into one platform that works alongside your existing HVAC controls and gives your schools an on-ramp to WELL certification.
Behind it all is a team that has led school districts, engineered building systems and protected health at the White House. We’re with you from the first install to your biggest decisions.
Know how every room is really used.
Every classroom monitor senses when its room is occupied. Across your district, that becomes a live record of how each building is actually used, including evenings, weekends and summer, not just how the schedule says it’s used.
Citadel turns the patterns into clear space-use reports for your planners, business office and board.
Your data. Your story.
Measuring the air raises questions. Citadel’s strategic communications experts help you answer them with confidence: board briefings, staff and parent updates, and parent and public views that show exactly what you choose to share.
When a parent, a board member or the local news asks, you’ll have the facts and the words ready, and your district gets the credit it earned.
Communication is one of six key drivers in the EPA’s framework for school air quality . We make it one of your strengths.
