Breeam a presentation by adrian doling technical director

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.


Breeam a presentation by adrian doling technical director

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 Procurement2.Fit Out3.Post Construction Review4.Management and OperationBespoke 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.


Breeam a presentation by adrian doling technical director

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.


Breeam a presentation by adrian doling technical director

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.
