EnMS Auditing Process Requirements • Audit plan – Scope of
audit • Audit team selection –
Skills required • Minimum time for audit
Auditor Competence Requirements • General competence • Sector-specific
competence
National Energy Efficiency Conference 2013

No experience with an EnMS – need guidance on implementation and development of an EnMS
EnMS established and operating – is it functioning and delivering energy performance improvements?
Have a functioning EnMS – how to improve upon and further develop the management system model

Types of EnPIs
EnPI Type Examples
Measured Energy Value
• Energy consumption for lighting • Fuel consumption of boilers • Electricity consumption during peak hours
Ratio of Measured Values
• kWh/ton of production • kWh/m2 of floor space • liters of fuel per passenger kilometer • Conversion efficiency of a boiler (%)
Statistical Model
• Model of production facility with two or more product types • Model of hotel with variable occupancy rate and outside
temperature
Engineering Model
• Systems where simulations enable adjustment for changes in relevant variables and their interactions.
• Model of electricity consumption of a chiller using cooling demand outdoor (condensing) and indoor (evaporating) temperature
• Whole building models

Other Issues related to EnPIs and EnBs o Defining EnPI Boundaries
- Physical, System-related, Organizational
o Target Management Level or Users - Top Management, Energy Manager, Plant or Facility Manager,
Operational or Maintenance Personnel
o Influence of Static Factors (e.g. change in product type, number of shifts per day, occupancy pattern or floor area of building, etc.)
o Data gathering for establishing EnPIs and EnBs: measurement accuracy, frequency and quality (refer also to ISO 50015)
o Determining when energy baselines should be normalized
o When should EnPIs and EnBs be changed/adjusted? (e.g. change in energy use, new process or other operational changes, or arising from management review, etc.)
National Energy Efficiency Conference 2013
o Scope: Establishes general principles and guidelines for the process of Measurement and Verification (M&V) of energy performance of an organization or its parts
o Overall aim of M&V: To provide confidence to interested parties that results are credible
o Key principles: accuracy and management of uncertainty transparency and reproducibility of process good data management competence of M&V practitioner impartiality confidentiality appropriate methodology

ISO TC242 is developing a suite of standards that will complement the ISO 50001 international energy management system (EnMS) standard
ISO 50004 will provide additional guidance to organizations interested in implementing an EnMS or improving upon their EnMS
ISO 50003 specifies requirements for the competence, consistency and impartiality in the EnMS auditing and certification process.
Three other technical standards are in the works. ISO 50002 sets out minimum requirements for an energy audit. ISO 50006 provides guidance to organizations on how to establish, use and maintain energy performance indicators (EnPIs) and energy baselines (EnBs). ISO 50015 establishes a common set of principles and guidelines to be used for measurement & verification (M&V).
The recently enacted Energy Conservation Act (ECA) can benefit from these ISO standards as they provide a globally acceptable process for most organizations and major industrialized economies.
