What to Monitor in a Building to Catch Problems Before Your Users Do
The best fault is the one your users never find out about. All it takes is knowing which readings to watch and when to be alerted.
In many buildings, the first sign of trouble is a phone call: the office is cold, the shop feels stuffy, the warehouse smells damp, or water is dripping from under a sink. That is the most expensive way to learn about the state of a building. Someone is already unhappy, and the damage has often already been done.
Monitoring and automation reverse that order: the technology tells you before the problem shows up in daily operation. You do not need to track everything. What matters is picking a handful of readings that most often come before real trouble. This builds on our earlier piece about retrofitting an existing property without construction work. For the basics, see Smart technology at intechi.cz.
Why catching it early pays off
Most operational problems do not announce themselves. Slowly rising humidity, a leak that drips a little at a time, a refrigeration unit cycling more often than usual, or ventilation that has stopped bringing in fresh air. These are all deviations that show up in the numbers before anyone feels them.
Monitoring therefore does not mean covering a wall in charts. It means having rules that alert you when something departs from the usual, and an overview showing where and since when.
Five groups of readings worth tracking
| Reading | What it tells you | Typical problem caught early |
|---|---|---|
| Temperature | Comfort, and whether heating, cooling and ventilation work | A zone that never warms up, or overheats; cooling failure in a store room |
| Humidity | Condensation risk and moisture damage | Persistently high humidity in a basement, warehouse or behind cladding |
| CO₂ (air quality) | Whether ventilation keeps up with occupancy | A meeting room where concentration and focus drop an hour into the session |
| Water | Leaks and unusual consumption | A small leak, a constant trickle of flow overnight |
| Energy and equipment status | How technology actually behaves | Equipment running out of hours or switching on more often than before |
Rule of thumb: Start where the damage is greatest or complaints are most frequent. For most sites that means water leaks, temperature and humidity in sensitive rooms, and consumption outside working hours.
What each reading can tell you
Temperature and humidity
A single value rarely says much; the trend does. A sensor showing 21 °C is fine. A sensor that only reaches 21 °C at ten every morning points to a heating schedule problem. Setting limits per zone gives far better results than one value for the whole building.
Humidity matters most where you store goods, paper, electronics or food. Slowly rising humidity is often the first warning that something is not ventilating, or that water is getting in.
CO₂ as a ventilation indicator
At everyday levels CO₂ is not harmful in itself, but it is a useful indicator of how well a room is ventilated. If concentration keeps climbing in an occupied room, ventilation is either undersized or not working as designed. Recommended values differ by standard, room purpose and source, so set limits with your own operation and your designer’s or operator’s requirements in mind.
Water
Leak sensors are among the quickest returns on investment, because water damage grows with the time the water was escaping. They go under sinks, by boilers and distribution pipework, in boiler rooms and at spots with a history of trouble. Consumption metering complements them: if water flows steadily at night, you learn about a leak even when no sensor sits right at the fault.
Energy and equipment status
Consumption over time is one of the most reliable signs that something is going on. Equipment that starts to draw more or cycles more often usually signals wear before it stops working. If the site has a solar power plant, it is worth tracking its output and self-consumption together with the rest of the building, so deviations in one place do not disappear in the overall total.
Examples from different types of property
Office. The focus is on CO₂, temperature and room occupancy. A meeting room where CO₂ regularly climbs exposes inadequate ventilation before colleagues complain.
Retail unit. Sales-floor temperature, refrigeration operation and consumption outside opening hours decide. An alert about a failing chiller or air conditioner arrives before the customer notices.
Warehouse. Temperature and humidity on the shelves, water ingress from the roof or pipework, and ventilation status. Protecting stock is usually the main benefit here.
Studio or showroom. Stable conditions for what is on display, and watching the space while nobody is present.
Setting alerts that make sense
A well-configured alert answers three questions: what happened, where, and who should be told. The usual mistakes are limits that are too sensitive (people stop reading), alerts without a clear recipient, and no follow-up step.
- Observe first, alarm later. A few weeks of data show what is normal for the space.
- Separate severity levels. Information, warning and critical events should not travel the same way.
- Name an owner for each type of event. A water leak goes elsewhere than a warm office.
- Check the response. After the first events, confirm the issue reached the right person.
Checklist: what to keep an eye on
- Water leaks – sensors at risk points and monitoring of unusual consumption.
- Temperature in key zones – offices, store rooms, technical rooms.
- Humidity where damage is possible – basements, warehouses, server room or archive.
- CO₂ in busy rooms – meeting and training rooms, open space.
- Off-hours consumption – you know what runs at night and at weekends.
- Status of key equipment – cooling, ventilation, pumps.
- An owner for each alert type – they know what to do.
FAQ
Do I have to monitor everything, or are a few readings enough?
A few is enough to start. Pick those where damage or user dissatisfaction is greatest and add more over time.
How do I know my alert limits are right?
Alerts are rare, and when they come they matter. If people ignore them, the limits are too sensitive.
Does this work in a building with older equipment?
Often yes. Sensors are added without construction work, and existing equipment can in many cases be connected to the same overview.
Who should receive the alerts?
The person able to resolve them. Different event types can have different recipients, while the overview stays in one place.
Can monitoring replace regular inspections?
It complements them. On-site checks stay important, but monitoring shows where attention is best spent.
From Sensor to Real Action
A reading is only useful once it turns into a concrete step. That is why data from all sensors comes together in one place and is available in the INTECHI client zone. Alerts reach the person responsible, and an event becomes a service request in INTECHI Digital Management in a single step. Equipment on site is registered, so the technician knows what they are going to. And since the solution grows gradually, you can start with one space and add more areas as their value becomes clear.
How INTECHI Approaches It
INTECHI TECHNOLOGY helps you choose the readings that make sense for your property, install them without disrupting operations and combine them into one overview with clearly defined alerts. We use the same technology as INTECHI at intechi.cz. If you want to know about a problem before your people do, get in touch.
