Scope – non-domestic

• All new buildings

• On sale of existing buildings

• On change of tenant in existing rented buildings

• Existing public buildings

Timetable – non-domestic

• New buildings – May 2007

• Existing buildings – 4 January 2009

• Duty to obtain/provide placed on owners

• Based on Asset Rating

( SBEM or approved software )

• Accompanied by a Recommendation Report

• EPC and Report for existing buildings

produced by ‘accredited assessor’

• EPC and calculations for new buildings may

be provided by ‘approved certifier of design’

SBSA protocols in place with:

Chartered Institution of Building Services


Association of Building Engineers

Energy Institute

Royal Institution of Chartered Surveyors

Protocol for existing buildings allows

professional institutions to agree standards for

accredited assessors who are members of that

institution and to enter them on a register held

by the institution.

• Assessors need to collect data on fabric,

services, floor areas and zones, usage

• Calculate Asset Rating using an approved

software tool

• Use recommendations report tool to produce

report of potential improvements

• Produce certificate and report

START 2008

Senior members of

institution with suitable

qualifications and

experience may become

accredited assessors for

existing buildings after

passing through

applications process

MID 2008

Objective to have

training available as part

of CIBSE’s ‘scheme

provider’ status for

approved certifiers of

design to allow CIBSE

scheme members to

become accredited



• CIBSE aim to become ‘scheme provider’ by

mid 2008

• Open to non-CIBSE members but applicants

must still have other relevant professional

qualifications / memberships

• Applicants must have relevant knowledge and

experience – training not designed for zero

starting point

Established by CIBSE in 2006. Proposed to

adapt this course to provide necessary

training for Energy Assessors for new or

existing buildings


Register has three sections. Individuals

may be trained and examined in:

• Low Carbon Building Design

• Low Carbon Building Operation

• Low Carbon Calculation & Simulation

To remain on the Register, members must

keep their knowledge up-to-date



• Advice on best practice in energy efficiency and

conservation, including passive design

• Advice on appropriate low carbon and renewable

technologies to enable designs to meet Building

Regulations and planning requirements

• Checks that completed buildings meet Part L in

England and Wales or Section 6 in Scotland

$ &"( '

• Measure energy consumption within a

building, and identify special circumstances

that may increase (or decrease) energy use

• Identify ways to reduce building energy costs

• Implement and monitor cost effective energy

efficiency improvements

$ &" '

• Originally for those wishing to certify accuracy

of carbon emissions calculations under Part L or

Section 6

• The register comprises

• LCC Calculation for SBEM based software users

• LCC Simulation for dynamic simulation users

• Will cover both carbon emissions calculations

for Part L or Section 6 compliance and asset

rating calculation and recommendations report

production for EPCs


• Those LCCs who are members of a suitable

professional body will satisfy most of the


• Top-up training is needed in competences not

already covered, eg. Asset Rating calculations

• The effect is that energy assessors will require to

have completed training that will entitle them to

entry on both the design and calculation parts of

the register


• All energy assessors will have to demonstrate

competence in putting data into the approved

software and operating the software to produce

an asset rating and the appropriate report.

• Those wishing to work with both SBEM

calculations and simulation will need to

demonstrate competence with both tools.


• CIBSE Certification will be applying for

approval to provide further schemes for:

• Complex air conditioning systems

• Domestic energy assessors (for members of the

non domestic scheme, to enable them to cover

large residential or mixed use buildings)

) "%

" "

• TM44: Assessment of air conditioning systems (A methodology

to satisfy the requirements of Part 4 of the EPB Regulations)

(Now available)

• Energy and carbon emissions regulations in buildings: a guide to


• New TM: Operational ratings

• New TM: Building energy benchmarks

• New TM: Asset ratings and energy performance certificates

• TM22: Energy assessment and reporting method (revision)

(Due first quarter 2008)
