Optimising energy consumption in new premises
PHM’s local companies DEAS and IQ Energy, as well as PHM Denmark’s personnel, moved to new premises in September 2024. IQ Energy, which specialises in reducing commercial and industrial energy consumption, immediately began to survey the property’s energy consumption and deployed its energy management system to monitor consumption. The aim was to ensure that the technical solutions in the modern building work efficiently and support sustainable energy use.
The IQ Energy solution combines existing data from the electrical, heating and water utilities, as well as the local building management system, and installs new metering points in the building. This gave an overview of energy consumption, which allowed the identification of potential savings. Even though the building is new and equipped with smart technology, the monitoring showed that energy consumption needed further optimisation.
Significant savings potential
The results of the analysis were impressive. IQ Energy identified a savings potential of nearly 100,000 kWh in electricity consumption and more than 70,000 kWh in heating by reducing ventilation times and lowering heating setpoints in the building, as well as closing radiator circuits during the summer season. The savings are equivalent to the annual consumption of 25 Danish households, reduce carbon dioxide emissions by 8.3 tonnes, and generate financial savings of almost DKK 200,000 per year.
In addition to monitoring electricity and heat consumption, IQ Energy also monitors the return temperature of the district heating system, possible water leaks, and solar power production. Comprehensive monitoring facilitates proactive measures and ensures energy efficiency all year round.
Development is driven by data
“The metering points had already been installed in the building, but we noticed variations in consumption habits. Therefore, we studied the operation thoroughly and took concrete measurements to analyse the problem directly from the data”, says Energy Engineer Mathias Alexander Levinsen.
Levinsen has been responsible for system deployment, database deployment, analysis and cooperation with DEAS and technical suppliers. He also emphasises the combination of theory and practice.
The data collected on lighting, ventilation, and heat and water consumption has been converted into concrete energy efficiency measures. The goal is clear: to ensure that the technical implementation meets the real needs of the property throughout the year.
“Solutions should work not only in theory but also in practice. In this case, as in many other cases, the energy data showed that the building management system setpoints needed to be optimised and that some of the technical equipment did not function as intended. We helped to identify the issues and found workable and measurable solutions”, Mathias Alexander Levinsen says.
IQ Energy is a company specialising in reducing commercial and industrial energy consumption using advanced energy monitoring software and retrofit technology.
