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. ELVs)
• Requirement for Environmental Management System
  to drive continual environmental improvement

6
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

7
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

8
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

9
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)

10
Overview of Guidance Note

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

11
Preparation

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

12
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

13
Analysis

• Energy performance of systems (or whole site) is
  assessed using appropriate energy performance
  indicators (EPIs)
• EPIs 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
  EPIs from other similar sites

14
Analysis (Contd)

• 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)

15
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

16
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

17
Eco-efficiency of the Industry Sector
18
Eco-efficiency of the Energy Sector
19
Conclusion (Contd)

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