6. The last day of each compliance phase (“the compliance date‟) is the date by
which the participant must have undertaken its ESOS Assessment and notified its
compliance to the Environment Agency.
For the first phase, this means that activity to support the ESOS Assessment
must have been undertaken between the 6 December 2011 and the 5 December
2015 to be considered compliant.
7. 7
ESOS applies to all undertakings that exceed certain qualification
thresholds (“large undertakings‟). It also applies to all members of a
corporate group which include at least one large undertaking in the UK.
If you are not in scope of ESOS, you are encouraged to still consider
undertaking energy audits voluntarily. Energy audits form part of
good energy management practice. Audits can help to identify
measures that can save energy and cut costs.
8. 8
If you have an ISO50001 Energy Management System (certified by an
approved certification body) covering all your energy use this shall be
sufficient to constitute an ESOS Assessment.
Notification to the Environment Agency of compliance is required
To be compliant, the system must have been certified during the
compliance period, and the certification must remain valid at the
compliance date.
9. 9
Measure your total energy consumption across a 12-month period (“the
reference period‟). The scope of ESOS includes energy consumed in:
buildings
transport
industrial processes
).
10. 10
Once total energy consumption is measured then identify your “areas of
significant energy consumption”
Significant energy consumption must account for at least 90% of total energy
consumption.
Within a phase, all areas of significant energy consumption must be covered
either by an ESOS Energy Audit or by an alternative route to compliance.
The remaining 10% of your total energy consumption does not require audit.
This energy use is referred to as de minimis energy used.
11. 11
Four distinct types of qualifying assessments and management activity :
ESOS Energy Audits - These may include any energy audit work undertaken
during the compliance period under other schemes (such as activity under
the Carbon Trust Standard, Logistics Carbon Reduction Scheme and Green
Fleet Reviews), provided your Lead Assessor confirms this work meets the
minimum standards required for ESOS Energy Audits)
An ISO 50001 certified Energy Management System
Display Energy Certificates (DECs) and accompanying advisory reports
Green Deal Assessments
MUST cover all of your areas of significant energy consumption in each
phase
12. 12
ESOS Energy Audits must be carried out by, or overseen/approved by,
recognised Lead Assessors (either in-house expert(s) or an external
individual)
Other routes to compliance are subject to separate requirements to be
considered valid for ESOS purposes – see Section 6 for more details.
Lead Assessors review audits carried out earlier in a compliance phase in
order to confirm that these meet the minimum ESOS standards.
Lead Assessor reviews ESOS Assessment as a whole, legal responsibility
remains with the organisation to ensure that all areas of significant energy
consumption are audited.
13. 13
ESOS sets minimum requirements for compliant ESOS Energy Audits.
ESOS Energy Audits must:
Use 12 months of energy consumption data, from within a specific
period
Use data not used to support ESOS compliance in a previous
compliance period
Produce cost-effective recommendations for the area being audited,
or confirm that there is no scope for cost-effective energy efficiency
improvement
Be overseen, conducted or reviewed by an ESOS Lead Assessor
14. 14
Organisation must notify the ESOS Scheme Administrator that they have
completed an ESOS compliant assessment for their organisation.
The notification must be made to the Scheme Administrator on, or before, the
compliance date of each phase. For the first phase is the 5th December 2015.
16. Participants in ESOS must have a Lead Assessor to undertake various roles in
relation to their ESOS Assessment. The exception to this is where a
participant has an ISO50001 certified Energy Management System.
The Lead Assessor may:
oversee the measurement of your total energy consumption
identifying areas of significant energy consumption
conduct ESOS Energy Audits.
approve audits carried out by others.. Or not
Lead Assessors must belong to a register of energy professionals approved by
the Environment Agency.
17.
18. 18
ESOS Evidence Pack should include:
details of the undertakings making up your participant and identification
of the responsible undertaking
details of the responsible board-level Director(s) or equivalents that have
taken the lead on signing-off compliance with ESOS.
details of your Lead Assessor
calculation of your total energy consumption.
list of your identified areas of significant energy consumption.
details of the routes to compliance used to cover each area of significant
energy consumption.
reasons, where applicable, for using less than 12 months of data for the
measurement of total energy consumption
details of the audit methodology used in your ESOS Energy Audits
reasons, where applicable, for being unable to use verifiable data
justification, where applicable, where your auditor does not consider an
energy consumption profile in their audit of an area of significant energy
use
