Glatthaar Keller GmbH & Co. KG commissioned us in 2020 to carry out an energy audit in accordance with DIN EN 16247-1. All sites were to be evaluated in terms of energy in order to identify potential savings in energy consumption, increase energy efficiency and thus optimize overall energy consumption.

We were allowed to accompany this exciting project and to carry out an energy audit for the 5 different sites according to DIN EN 16247-1. The multi-site method was used to significantly reduce the effort and thus save costs.

Mandatory energy audit according to DIN EN 16427-1 for all non-SMEs

The EU Energy Efficiency Directive stipulates that all companies that are not small and medium-sized enterprises (SMEs) according to the EU definition must conduct an energy audit. Since 2015, the German government has implemented this EU requirement into national law by adapting the Energy Services Act (EDL-G).

As Glatthaar Keller GmbH & Co. KG is subject to the energy audit requirement, they are obliged to carry out an energy audit in accordance with DIN EN 16247-1 every 4 years. Here we took care of a smooth planning, cost-efficient implementation and handling of the energy audit in all 7 phases.


The first contact: Prelude and project scope

A permanent contact for the customer on our side during the whole project duration is a matter of course for us. This person knows the exact project status at all times and is available to the customer for questions and arrangements.

Prior to the actual energy audit, a kick-off meeting was held with the customer, the personal contact person at our company and an audit expert from our technical department in order to clarify all organizational matters, such as the timeframe, resources, objectives and scope of the audit. We then worked with the customer to further specify and plan the implementation of the energy audit so that this would also be in line with the customer’s internal processes and fit seamlessly into the corporate process.


Energy Performance Indicators (EnPI): Important key figures for increasing energy efficiency

Energy management without the right key figures is impossible. They form the foundation for demonstrating improved energy efficiency. Here, we address the needs and goals of our customers individually.

Therefore, our auditor obtained an overview of all factors that play a role in the customer’s energy efficiency. Important individual energy indicators, such as the proportion of total energy consumption accounted for by the individual sites, are then defined and given special consideration during the audit. In this way, the customer received suitable key figures geared to its goals.


On-site inventory: transparency of all energy flows

Our auditor visited the customer’s various sites and took all the necessary measurements. Particular attention was paid to the uninterrupted recording and value plausibility of all energy consumption data. This means that all energy flows are presented in a 100% transparent manner.

With the inventory, we were able to map the customer’s complete actual energy situation. On this basis, our auditor determines possible energy saving potentials. After comparing the defined energy targets, suitable measures are derived to increase target achievement.


Crowning conclusion: audit report with concrete options

Following the complete data collection, the customer received a presentation of his energy audit report, in which our auditor identified concrete savings opportunities. Together we discussed the results and discussed further measures. All this was always done with the aim of sustainably reducing energy consumption and energy costs. Of course, the customer received the audit report again in digital form afterwards, so that further simple implementation within the company is ensured.


Multi-site procedure: Cost-efficient implementation

Does every site have to be visited by the auditor? Quite clearly no! If a company has several sites, the multi-site procedure can be used. In this case, the energy audit is carried out at a representative selection of sites, so that the effort involved can be significantly reduced.

At the beginning of the project, we also examined whether the multi-site procedure could be applied to the auditing and were thus able to save costs for our customer during the implementation.


Our 360° view: Sustainable improvement of energy efficiency

We keep an eye on all energy guzzlers. We identified major energy consumers for the customer and developed suitable efficiency measures to achieve a sustainable improvement in energy efficiency. An energy audit thus paid off for the company and for the environment, helping to achieve the customer’s targeted climate goals and reduce energy costs in the long term.
