Average temperatures are rising all over the world. In fact, the World Meteorological Organization reports that the last seven years have been the seven hottest on record with average global temperature rising above pre-industrial levels every year since 2015. This trend is set to continue – and has huge implications for the growing number of people who are at high risk due to a lack of cooling.

The growing gap in access to cooling is a huge challenge as working and living conditions are becoming more and more unbearable. One solution is to use air conditioners and electric fans to stay cool, but this accounts for nearly 20% of the total electricity used in buildings around the world today. Something needs to be done – without action, energy demand for space cooling will more than triple by 2050.

Today’s energy challenges require smarter, more energy efficient cities focusing on sustainable use of resources. Smart solutions like district cooling play a crucial role in this development.


District cooling provides chilled water to industrial, commercial, and residential buildings via a closed pipeline network. Functionally and technically, it is similar to district heating networks – and is becoming popular worldwide. In Europe alone, 40% of commercial and institutional buildings have cooling systems, and this number is rising rapidly. The Middle East has quickly adopted district cooling technology and currently accounts for between 15% – 25% of the world’s installed cooling capacity. District cooling can be generated from local natural resources like seawater, or from chillers powered by steam or electricity.

The benefits are significant, as district cooling 

  • is up to 60% more efficient than conventional air conditioning.
  • emits significantly less CO2 than conventional cooling systems.
  • emits no hazardous refrigerants.
  • is discreet and quiet.
  • is able to reduce energy consumption for cooling by 50% through better energy use.
  • can be can be produced from renewables like sea water or waste heat.

Ultimately, district cooling is an environmentally friendly solution that is reliable and highly secure.

Cooling meters Cooling meters


Metering solutions are important for the success of district cooling systems. Not only they enable more accurate billing but they also help to optimize energy consumption and minimize production costs.

Diehl Metering’s SHARKY 775 smart ultrasonic cooling meter, along with the more compact SHARKY 774 smart ultrasonic cooling meter, are among the best on the market for six key reasons:

The frequent data gathered from smart cooling meters like SHARKY can be used for more in-depth analysis offering improved benefits around energy savings or energy efficiency optimization. Frequent meter data also provides additional insights such as information about the performance of the cooling distribution network.

There are two remote reading solutions for you to consider, each meeting specific requirements

Mobile Readout

Diehl Metering's Automatic Meter Reading (AMR) solutions enable walk-by or drive-by reading, making mobile readings simple and intuitive. A connection to a portable radio receiver transforms your tablet into an efficient meter reading tool.

Fully automated Readout

If you need high-resolution data or a fully automatic readout on an hourly or daily basis, a wireless or wired M-Bus fixed network from Diehl Metering is the perfect choice for you. An advanced network infrastructure (AMI) allows you to see your network with new eyes and use readings for purposes beyond billing. You can get closer to your end-consumers, give targeted advice, and reduce your customers’ cooling bills, while optimizing the performance and efficiency of your network.

What you choose depends on your needs. However, what is clear is that moving away from manual readings to fully automatic or mobile reading allows for more frequent readings and higher-quality data from your smart meters.
