General information

DIN EN 16247-1 energy audits – part 1: General requirements (DIN EN 16247-1:2012) is a European standard and offers a clear, uniform structure in terms of the execution of energy audits (see graphic: elements of the energy audit process) across all industries by stipulating the respective requirements, methods of operation and findings.

Content

By applying DIN EN 16247-1:2012 the current status of the company in regards to energy is established, meaning that the energy input, energy use and energy flows within the company are identified. On this basis individual suggestions are developed in order to increase energy efficiency as well as to reduce energy consumption within the company.

Context in regards to legal stipulations

EDL law

Based on the amendment of the law on energy services and other energy efficiency measures (EDL law), all companies, which are not small or medium-sized companies, shall be obligated to carry out an energy audit in accordance with DIN EN 16247-1 by 5th December 2015 as well as to repeat the process every four years unless they are able to provide a certification regarding an energy management system in accordance with DIN EN ISO 50001 or a validated environmental management system in accordance with EMAS.

SpaEfV

Small and medium-sized companies (KMUs) within the production industry have the option to have electricity and energy tax reimbursed as per the peak compensation efficiency system order (SpaEfV) (§10 StromStG / §55 EnergieStG) as long as they verify by 31st December that they carry out an annual energy audit in accordance with DIN EN 16247-1 (or an alternative option*), which is finalised by means of an energy audit report. Regarding non-KMUs, an energy audit in accordance with DIN EN 16247-1 is not sufficient, but rather a certification concerning an energy management system in accordance with DIN EN ISO 50001 or a validated environmental management system in accordance with EMAS is required. 
Information in regards to the simplification of procedures for KMUs, which allows for an alternative system in accordance with SpaEfV, please refer to the paragraph on energy management – section on SpaEfV.

Alternative possibilities in terms of energy audits in accordance with DIN EN 16247-1 (*)

  1.  a certification concerning an energy management system in accordance with DIN EN ISO 50001,
  2.  a validated environmental management system in accordance with EMAS or
