A Study on Energy Efficiency in Enterprises: Library of typical energy audit recommendations, costs and savings

Share this Post:

 

Under Article 8(1) of the Energy Efficiency Directive (EED), Member States must promote the availability to all final customers of high quality energy audits which are cost effective and (a) carried out in an independent manner by qualified and/or accredited experts according to qualification criteria; or (b) implemented and supervised by independent authorities under national legislation.

 

This study, elaborated by DNV GL for the European Commission, aims to support the Commission by providing an overview of current implementation practices, tools and instruments related to Article 8 of the EED within the different Member States. This report, specifically, addresses the development of a library of typical energy audit recommendations, costs and savings. In the sections that follow, this task is split into two principle components:

 

  • the compilation of representative data on the relative cost of energy audits;
  • the creation of a library structure, within which typical audit recommendations and their projected savings are listed. These represent the most significant energy efficiency opportunities.

 

The report conclusions are, among others, the following:

 

  • Auditors need to work with real energy consumption data and company characteristics, often have to “hunt down” the necessary data, verify obtained data or even provide special measurements when information is lacking. The availability of correct company information is, therefore, of significant importance when determining the energy audit cost.
  • Differences in audit costs are also apparent in different Member States. Tax laws, the general cost of living, energy costs, reporting requirements, auditor qualifications, etc. are all very important issues influencing audit costs. Based on the limited cost data available, it is, however, not possible to draw general conclusions regarding the price differences in different Member States.
  • Several Member States have developed (or are in the process of developing) an online tool or application, which has to be used by large enterprises or energy auditors to upload the results of the mandatory energy audits. Monitoring bodies typically request information on the auditor and the audit recommendations (amongst other information). These national web applications could be a very helpful tool in the development of a more complete and accurate European-wide database, listing the most common audit recommendations and also providing accurate and more in-depth information on the energy audit costs in different Member States, and the basis of these price calculations.
