BREEAM Pre-Assessment: reading the credit tracker

A BREEAM Pre-Assessment is the document that tells a planning authority what environmental rating a non-domestic scheme expects to achieve, and it is built around a credit tracker: a line for every credit in the scheme, with a judgement about whether the design will earn it. Read properly, that tracker is a risk register. Read carelessly, it is a spreadsheet that makes a target look inevitable when it is not.

Councils ask for a rating because their local plan says so. Sustainable construction policies commonly require non-residential development above a floorspace threshold to achieve a named rating, and the pre-assessment is how compliance is demonstrated at application stage.

Why the rating ends up in a condition

The requirement usually reaches the decision notice as a condition rather than an obligation. That matters, because a condition has to be precise, enforceable and reasonable to be lawful, and a badly drafted rating condition is difficult for everyone.

The common form requires submission of a design stage certificate before a defined point in the works and a post-construction certificate before first occupation. That is workable. What is not workable is a condition requiring a numerical score with no tolerance, or one referring to a scheme version that will have been superseded by the time the building completes.

Name the scheme and the version in the condition. Agree a mechanism for dealing with a scheme update. And where the target depends on something outside your control, say so at the time rather than at discharge.

What the pre-assessment document contains

A pre-assessment worth submitting has five parts.

A description of the building and the assessment scope, including which scheme applies and which building type is being assessed, since the available credits differ between them.

The credit tracker itself, issue by issue.

A weighted summary showing the score by category and the resulting rating, with the margin above the threshold stated in percentage points.

A schedule of the minimum standards for the target rating and confirmation that each is met.

And a list of the design decisions the score depends on, with an owner and a stage for each.

That last part is what separates a document that helps from one that is filed. A tracker without owners is a prediction. A tracker with owners is a programme.

Reading the tracker

Every credit should sit in one of three states, and the language should be unambiguous.

Targeted means the design already delivers it and the evidence route is known. These are the credits you can count on.

Potential means the credit depends on a decision not yet taken: a specification, a supplier, a survey result, a contractor's procedure. These credits are real but conditional, and the tracker should say what the condition is.

Excluded means the credit is not available or has been abandoned, with the reason recorded. A tracker that quietly omits unavailable credits rather than listing them with a reason is hiding its own margin.

Then look at the margin. A scheme sitting two percentage points above the Excellent threshold with a third of its score in potential credits is not an Excellent scheme yet. A scheme sitting six points above with almost everything targeted probably is. That comparison takes a minute and it is the single most useful thing a developer can do with the document.

Minimum standards that cap a rating

Each rating level carries mandatory minimum requirements in named issues. Miss one and the certified rating is capped below the score you calculated, which is the failure mode that produces the difficult conversation eighteen months into a build.

Several of these are design decisions rather than specification choices, which means they have to be settled early. Energy performance, water consumption, responsible sourcing of materials, construction site management and the commissioning and handover process all appear in the minimum standards at higher rating levels in one form or another. Take the list for the target rating from the scheme document and check each item against the design before the pre-assessment is issued.

Where the licence matters

Formal certification is a licensed activity. The scheme operator licenses assessors, and only a licensed assessor can register a project, submit the evidence and obtain a certificate.

A pre-assessment can be produced by a design team member using the published estimator, and often is. That is fine at feasibility stage, but if the council's condition requires certification then a licensed assessor has to be appointed, and appointing them at pre-assessment stage generally produces a better score because the evidence route is designed in from the start.

Where a report describes itself as a pre-assessment, check who wrote it and whether they hold the licence. It changes how much weight the number deserves.

Design freeze and the gap to post-construction

The design stage assessment is a snapshot. Value engineering after it produces the classic failure: a credit for a specification that was substituted, a credit for a commissioning regime the contractor did not price, a credit for a travel plan that never had a coordinator.

Three habits protect the rating. Put the credit requirements into the employer's requirements or the specification rather than into a separate report. Make the assessor a party to change control, so substitutions are checked against the tracker before they are agreed. And keep the evidence as it is generated, because reconstructing procurement records at post-construction stage is slow and sometimes impossible.

Site-based credits are the ones lost most often, since they depend on procedures during construction rather than on drawings.

Innovation credits and where the margin comes from

Innovation credits sit outside the weighted category total and are added to it, which makes them the least costly route across a threshold when a scheme is a point or two short.

They come from two sources. Exemplary performance in a named issue, where the scheme goes beyond the top standard credit and the scheme document allows an additional credit for doing so. And approved innovations, where a product, process or approach has been recognised by the scheme operator.

Exemplary credits are the practical ones, because they usually follow from a design decision the scheme was heading towards anyway. Check which issues offer them early, since the exemplary requirement is often only slightly beyond the standard one and the decision is much easier before a specification is fixed.

What innovation credits should not be is the plan. A pre-assessment relying on three speculative innovation credits to reach its target has no margin at all, and that is exactly the situation the tracker should make visible rather than obscure.

Keeping the sustainability documents consistent

The pre-assessment sits alongside the other environmental documents and reviewers compare them. The Energy Statement should use the same modelled performance figures that the energy credits rely on. The Sustainability Statement should describe the same measures. Where the scheme is large enough for a Whole Life Carbon Assessment, the material assumptions should match those behind the materials credits.

Inconsistencies between these documents are noticed. They also tend to be the first thing a consultee picks up, because comparing three tables is quicker than checking one calculation.

A pre-assessment is technical work and councils usually expect a suitably qualified author, so use an AI-assisted draft for the policy framing and the report structure and have the credit scoring done by a licensed assessor.
