IPC Licensing

      Principal policy response to regulating industrial pollution in Ireland Addresses all sites with significant polluting potential Commenced in 1994 Covers all potential environmental impacts of a site Use of BATNEEC (e.g. ELV’s) Requirement for Environmental Management System to drive continual environmental improvement

IPPC Directive

 Energy efficiency auditing was not a specific requirement of the older IPC licences  In anticipation of the transposition of the directive into Irish National legislation, energy efficiency audits became mandatory in IPC licences from 1999 onwards  IPPC Directive transposed into Irish National legislation in 2003

IPC Licence Requirements

   Audit to be carried out within one year of date of grant of licence  Nature and extent of audit programme to be agreed in advance with EPA  Audit recommendations to be incorporated into sites Environmental Management Programme Summary of audit findings to be submitted to the EPA Audit to be repeated at intervals as required by the EPA

What is an Energy Efficiency Audit?

 A systematic process to determine the quantity and cost of each form of energy to a building, process, manufacturing unit, piece of equipment or a whole site  Carried out to cover a given period of time

Development of the Guidance Note

     Published in 2003 Designed to be a simple and generic guide to the audit process Can be used by an on-site operator or contractor Encourages a continuous, cyclical auditing process Also acts as a source of information on energy mangement (websites, reference documents)

Overview of Guidance Note

 Process is broken down into discrete steps  Preparation  Execution  Analysis  Reporting

Preparation

  Designation of responsibilities Determination of scope of audit (e.g. areas to include in audit, collection of existing energy data, etc.)

Execution

 Assessment of each of the energy-consuming systems on site  Comparison of sites energy management system with best practice  Guidance is provided for these steps

Analysis

   Energy performance of systems (or whole site) is assessed using appropriate energy performance indicators (EPI’s) EPI’s provide a means of quantifying energy costs and consumption against important factors such as level of production or site occupancy, etc.

Energy performance can be benchmarked against EPI’s from other similar sites

Analysis (Cont’d)

    A list of recommendations is identified to improve energy performance at the site A set of actions is developed with responsibility, target dates and resources being allocated for implementation Guidance is provided in quantifying actions in terms of energy savings, cost savings and return on investment Recommendations for action must be incorporated as Objectives and Targets into the sites Environmental Management Programme (requirement of the IPC licence)

Reporting

 It is a licence requirement that two reports be prepared for each energy audit  Main report – to be maintained on site  Summary report – to be submitted to the EPA as part of the sites Annual Environmental Report

Conclusion

  Response from Industry has been positive Too soon yet to say what impact the Guidance Note will have on Irish Industry in terms of energy efficiency  IPC licensing system has probably had a positive impact on the industrial and energy sectors with regard to energy efficiency over the last ten years

Conclusion (Cont’d)

 Hopefully, the development of a lower energy intense economy has begun in Ireland
