Tech Tip #57: Predict, don't just react

A smarter controller cut greenhouse energy by over 60%.

Video created by explainapaper.com

The problem

Control software for buildings, devices and plant often switches equipment on and off at fixed thresholds, reacting late and overshooting.

The fix you can use today

  • Forecast the next few minutes from sensor data and act ahead of time.
  • Start with simple, explainable models before deep ones.
  • Compare energy and stability against the threshold controller.

GreenCode researchers found that a predictive controller cut greenhouse energy use by over 60%.

Tools that help

  • CodeCarbon: a Python package that estimates the energy and CO2 of a run from hardware power and regional grid intensity

How GreenCode helps

GreenCode helps tackle this by measuring what critical software demands of its power supply and reducing it, with quality, security and error rate checked at every pass, so systems run longer on backup or limited power. More on this.

A smarter controller cut greenhouse energy use by over sixty percent. Lots of control software works on fixed limits. Too hot? Fan on. Too cold? Heater on. It reacts late, and then it overshoots. That wastes energy, in buildings, devices and machines. Here is the fix you can use today. First, forecast the next few minutes from your sensor data. Then act ahead of time, not after the fact. Start with simple models you can explain, before deep ones. Then compare energy and stability against your old controller, using tools like CodeCarbon. GreenCode researchers found that a predictive controller cut greenhouse energy use by over sixty percent. That was against a fixed-limit controller, and the climate stayed stable. GreenCode helps tackle this by measuring what critical software demands of its power supply. It cuts that demand, so systems run longer on backup or limited power. That was GreenCode Tech Tip number fifty-seven. Follow for the next tip, and find more on greencode.ai/tech-tips.
