There are many sensors on the market suited for temperature measurement. A company I personally like is Disruptive Technologies with their stamp-sized sensors. Recently I have been challenging myself, while also having good conversations with Disruptive Technologies and their customers to look for creative ways to use the sensors — to give me good insight into commercial buildings in particular.
When you traditionally think of temperature, it is often connected to regulating heaters and room control. I have tried to be a bit creative at our living lab|Proptech Bergen and in this article I will show three examples.
Using a temperature sensor on pumps can give you a simple indication of whether pumps are running or not. In the example, it is the chiller pump located in a room that is around 25 degrees; when the pump starts it quickly reaches 40-50 degrees, and I have created some simple rules that display this as a status. I also use data to predict if something is wrong — for example, if it gets warm, starts and stops, and similar. The image is taken from Proptech Bergen where we do not have pumps with communication, which means you can keep existing pumps through their lifespan while still making them smarter.
The most important energy component in a ventilation system is the heat recovery unit. If you have a modern rotary heat exchanger, the efficiency should ideally be 80-88%. If you do not have a functioning BMS (where this has actually been integrated) or a functioning stand-alone system, you can easily use sensors to calculate the efficiency in a simple way.
By using a temperature sensor on the underside of desks, you can clearly see the usage pattern and whether workspaces are free or occupied. It may not be quite as accurate as sensors in chairs that show digitally on/off, but this method also takes into account whether someone is standing.
We have also tested temperature on electrical panels, critical components, routers, servers and similar to provide warnings if we detect anomalies — we hope to be able to share some exciting findings around this later.
Do you have a creative suggestion for where temperature can give you new insights?
