What’s the key to successful energy management with deZem?
The potential for energy savings is huge, but it is rarely fully utilised. This is where energy management can play a decisive role. The agile approach of deZem enables particularly effective energy management.
Energy management according to ISO 50001
Energy management according to ISO 50001 follows a cyclical process, involving the implementation of energy-saving measures in businesses, buildings, and municipalities. The goal is to increase energy efficiency, reduce costs and minimise CO2-emissions. The basis for this is the PDCA cycle, i.e. planning, implementing, reviewing and learning from energy efficiency measures.
Building on this, we at deZem have developed SENSE, CHECK, ACT, an agile approach that complements the PDCA cycle and facilitates the introduction of ISO 50001.

Rapid success with SENSE, CHECK, ACT
Although projects typically begin with planning, we recommend starting with data collection instead. The reason is simple: with minimal effort, you can quickly gather high-quality data - the perfect foundation for planning and implementing effective optimisation measures.
The improved data transparency enables our customers to quickly identify inefficient system settings and achieve substantial energy savings through needs-based control - usually without expensive investments in new equipment.
Agile IoT sensors & software
Our approach ensures agility by quickly establishing a flexible metering infrastructure with IoT sensors, LoRaWAN and our deZem DataSuite - a high-performance and secure energy management software. It processes almost any type of (metering) data, and existing customer systems can be easily integrated via the appropriate interfaces.
Advantages of agile energy management:
SENSE, CHECK, ACT
- Fact-based basis for decision-making (reduced risk of misinvestment and planning revisions)
- High effectiveness through customised optimisation measures
- Quantitative performance review (before/after measurement data available)
- Agile implementation and rapid savings effects in just a few weeks
- Targeted non-investment measures possible
- "Low hanging fruits" are quickly recognised and realised
- Quick start pilot projects are carried out at major loads, followed by a wider rollout
Energy management at Bayer AG
Bayer AG uses the deZem system worldwide
- 10,000 measurement traces of various kinds
- Monitoring of machines: Energy use and energy demand forecasts and much more
- Identification of potential savings such as stand-by minimisation
- Detection of consumption peaks
- System optimisation:Monitoring of load profiles, predictive maintenance

Our tip:
Climate control and ventilation systems account for 30–50% of total energy consumption in many buildings and are often not optimally configured. With sensors and smart controls, the air exchange rate can often be halved - without any loss of comfort! This could reduce electricity costs to one eighth. Many of our clients have achieved these impressive results without expensive investments and in a very short time. The Harvy2 power sensor is perfectly suited for this purpose.

Why is energy management a smart choice?
- Cost reduction: Energy costs can be significantly reduced by utilising resources more efficiently.
- Legal requirements: More and more companies are subject to new legal requirements to increase their energy efficiency (ESG reporting, EnEfG) and to provide evidence of this via an energy management system (EnMs).
- Climate and environmental protection: Energy management improves the CO2 footprint and conserves resources.
- Competitive advantage: Lower energy costs and optimised processes give companies a decisive advantage.
- Image boost: Positive public image and image enhancement through sustainable action.
- Increased transparency: Better understanding of energy flows and sensitisation of employees to energy-saving measures.
- Reporting tasks: Simple creation of interdisciplinary reports for internal and external stakeholders or departments (e.g. controlling, management, technology, authorities, etc.)
- Load management: By avoiding peak loads, grid charges can be reduced and production can be adapted to dynamic or fluctuating electricity prices.
- Fact-based support for energy purchasing and billing
What are the building blocks of energy management in accordance with ISO 50001?
- Record and analyse energy consumption Key energy users (SEUs) and their EnPIs are recorded and analysed. DeZem provides the right products for this: smart IoT sensors, measuring devices, and a powerful energy management software called DataSuite.
- Define energy targets: Based on the EnPIs collected above and the preceding analysis, energy targets are defined, in particular for the SEUs
- Implement efficiency measures: Appropriate measures are developed and implemented in order to achieve the planned energy targets.
- Energy monitoring & control: Continuous monitoring ensures that implemented measures are effective. The deZem DataSuite provides valuable support in this process.
- Continuous improvement process: Energy management is a dynamic process that constantly adapts to new conditions. Regular reviews and adjustments (PDCA cycle) make the system more efficient and effective.
