Energy savings through IoT

Share This:

With the global trend of rising temperatures due to the El Nino phenomenon, it’s no surprise that you’ll probably see a huge increase in your electricity bill lately. The major consumption in electricity is your air conditioning or heating systems, which makes-up 60-70% of your total electrical consumption. If you’re lucky, you can get your hands on a Nest, the best & more mature IoT line of products out there, to monitor your consumption & start savings (retails at USD 249 )

According to the company, the Nest thermostat saved people an average of 10-12% on heating bills and 15% on cooling bills, which means it pays for itself in under two years. If you’re a building owner for a hotel, shopping mall etc., imagine the savings you can achieve! However, before you start to install hundreds of Nest in your building, stop! HVAC (heat ventilation & air conditioning) for commercial buildings are a bit more complex, most in the tropics uses large chillers to produce chilled water at 4-6 deg C to cool entire buildings. (see How do chillers work?)

The good news is there’s a similar IoT system from iCEE that monitors & optimizes the energy consumption of chillers for any large buildings which can even achieve savings up to 20%.

Intelligent Chiller Energy Efficiency system

The iCEE System uses engineering principles and optimization formulation to achieve true and tangible energy savings for clients.It is designed to reduce the energy usage of these chillers while maintaining the internal thermal comfort of the occupants in the building & compatible with all air and water cooled chillers, running on centrifugal, screw, scroll, and reciprocating compressors. The system will determine the actual building’s or facility’s heat load by placing Relative Humidity (RH) and Temperature sensors located strategically at the external and internal area of the building together with Resistance Temperature Detectors (RTD) in the chilled water and condenser water piping system of the chillers. Facilities maintenance teams & even building owners will be able to view & monitor sensor data & savings calculations in real-time from tablets & mobiles with customisable dashboards.
