ESOS Assessment

• Measure all energy use for a continuous 12 month period

• Undertake audits covering all their main areas of energy consumption

• Report compliance to the Environment Agency, as scheme administrator by the compliance date.

Energy audit compliance

• By 5 December 2015 and every four years thereafter

Energy audits

• At least 90% of total energy use is subject to ESOS energy audits or an alternative route to compliance:

(i) where an entity has in place an energy management system (certified to ISO 50001 Standard)

(ii) where an entity has in place an energy audit through the Green Deal or to obtain Display Energy Certificates (DECs) (where accompanied by recommendation report)

Using existing energy audits to support compliance

• Work undertaken to obtain other audits and assessments:

- Carbon trust standard

- Green fleet review

- Work undertaken as part of an energy or environmental management system (e.g. ISO 140001 Environmental Management System)

- Data gathered under CRC or other governmental schemes

Auditor requirements

• Appoint a Lead Assessor to lead ESOS assessment process

• Work undertaken by staff with appropriate knowledge and experience

• All areas of significant energy consumption must be addressed

• Lead Assessors can be internal staff or external professionals

• Lead Assessors must belong to an “approved register”

Recommendations for cost effective energy efficiency measures

• Estimated costs and benefits

• Examples:

- Installing smart meters

- Improvements to service and maintenance

- Replacing enterprise travel with video conference

- Capital investment projects

- Behaviour change pattern

• Case study – Net present value

Case study

Life cycle cost analysis – “LCCA”

• Boiler replacement

- capital cost

- utilisation cost

- maintenance/running costs

- Counter factual costs

• Net present value
