4. Pre-Assessment Estimator
A Pre Assessment Estimator is available for anyone to do a
quick check on how well a scheme may perform. An up to
date Pre Assessment estimator is available from the BRE
Website (PLEASE USE WITH CAUTION)!!!!!!
•
Tool to get a first estimate rating
•
Uses points (pre-weighted)
•
Very approximate
•
Final rating may differ
•
Certificates not issued for pre-assessments.
4. Formal Assessments
All formal assessments have to be carried out by a qualified
assessor under license from the BRE.
The role of the assessor is to support the development team
with simple cost effective approaches to enable the highest
possible rating for minimum capital cost.
The elemental approach to BREEAM ratings provides
flexibility in a scheme specific framework. Assessor require
documentary evidence via the developer / designers to
estimate the performance of the building and confirm the
rating.
4. Formal Assessments
There are currently four types of assessments as follows:
1.
Design and Procurement
2.
Fit Out
3.
Post Construction Review
4.
Management and Operation
Bespoke assessments are carried out on buildings not
covered by a standard set of assessment criteria.

5. Post Construction Review
•
Requested by English Partnerships for all their buildings
•
Now a requirement under the Code for Sustainable Homes
•
Reviews may need to be carried out on individual houses as
they are completed (because this process is part of the land
release)
•
Can be carried out by the same assessor who carried out the
design assessment.
5. Post Construction Review
•
The assessor should register the requirement for a PCR at the
design stage of the assessment
•
The procedure involves checking that the development details
agree with the design assessment
•
BRE have a written procedure for assessors to follow.
5. Post Construction Review
•
Documentary, photographic and video evidence may all be used
to demonstrate compliance
•
BRE performs higher levels of QA on PCR’s and so fees are higher
than for design stage assessments. This will need to be reflected
in the assessment fees
•
BRE is likely to perform a site audit of developments receiving
PCR’s.
