Smart buildings and sensors for property managers: start with one question

"Smart building" can mean almost anything, from a few leak sensors to a fully connected property. For a property manager the useful approach is narrow: choose one question that costs you money or causes complaints today, and see if sensors can help answer it.

Good first questions

• Where are leaks starting, and can we catch them before they damage units?
• Which chillers, pumps or lifts are running badly before they fail?
• Are common areas being cooled or lit when nobody is there?
• Are temperature and humidity staying in a healthy range in key rooms?

Each of these has a clear cost, and each can be measured before and after.

Start with one use

Resist the idea of connecting everything. One well-chosen use, such as water leak sensors in riser cupboards or run-time monitoring on critical pumps, is easier to install, easier to explain and easier to judge.

Data is not the same as action

A sensor that sends an alert nobody reads is only a cost. Before installing anything, decide:

• Who receives the alert, and at what hours?
• What do they do first?
• How do we record what happened?
• How do we avoid alert fatigue from false alarms?

If you cannot answer these, the technology is not the bottleneck yet.

Connect it to the work

The best results come when alerts create a job in your maintenance system automatically, with the location and the likely cause. That links the sensor to the process you already run.

Practical points to check

• Power and connectivity. Battery life, signal in basements and shafts, and who maintains the network.
• Ownership of data. Who owns the readings, and can you take them to another system?
• Installation access. Permissions from owners and tenants where needed.
• Privacy. Sensors in shared and technical areas are easier to justify than anything that could track people.

Pilot, measure, then decide

Choose one building, install for a defined period and compare against the previous period: faults found early, repair cost, complaints, energy use. If the numbers support it, extend it. If not, you will have learned that cheaply.
