DIN EN 16247 energy audit


On 5 November 2014, the Federal Cabinet adopted a bill to implement the EU Energy Efficiency Directive (EED), which was converted into German law at the end of April 2015. Since then, every company with non-SME status (small and medium-sized enterprises) - and thus also Deka - has been obliged to undergo an energy audit in accordance with DIN EN 16247 every four years. The energy audit acts as a consulting audit and aims to determine the overall energy efficiency and the associated improvement measures in the company in order to improve the energy balance.
 
In the run-up to the energy audit, Deka set up a cross-unit Energy Management Task Force, which prepared and accompanied the audit process. In addition to environmental management, the working group included persons responsible from the Real Estate Business Area in order to provide important data on the buildings to be inspected.
 
In cooperation with the independent energy auditors of Drees & Sommer, the properties mentioned were then subjected to detailed inspections. At the end of 2015, for example, an energy audit in accordance with DIN 16247 was one of the first giro centres to be carried out within the statutory requirements. The final report by Drees & Sommer confirms that "all properties are in very good structural and technical condition and generally require little optimisation".

Based on the results of the 2015 energy audit in accordance with DIN 16247, Deka 2017's real estate management was able to implement numerous measures to reduce energy consumption. For example, the lighting in the Trianon office building in Frankfurt was gradually switched to LED technology and the control of the elevators was made more energy-efficient. At the Prisma site, the corridor lighting was replaced by LED lamps. Economic efficiency calculations are regularly carried out for the individual measures. After that, the installation of LED lighting fixtures, for example, pays for itself after only a few years, based on the assumptions made for times-of-use and the electricity price.

 
These and numerous other measures enabled energy consumption to be reduced by around 3.8 percent to around 18.8 million kilowatt hours (kWh) in the year under review. Energy intensity in 2017 was 5,357 kWh per employee. This corresponds to a decline of more than 9 percent (2016: 5,893 kWh per employee).
