Within 1 week, clarity on what your building can truly certify
An independent feasibility analysis for BREEAM — with additional insight into health (WELL) and broader sustainability ambitions.
Results within 5–7 working days. No obligations. You’re not tied to anything. Use the report internally or move forward — with or without me.
Why many quick scans give a false sense of certainty
Many quick scans focus on theoretically achievable pointswithout critically assessing the evidence and substantiation required later.
The result:
- Unachievable targets
- Scores that appear feasible on paper
- But cannot or can barely be substantiated
- Leading to credits being rejected later
- Resulting in extra costs, redesign, and discussions
A feasible point without realistic documentation is not certainty — it is delayed disappointment.
The Certification Reality therefore looks not only wat at what is possible, but especially at what is demonstrable and defensible towards an assessor.. What we do differently:
- We assess not only the score, but the level of evidence
- We evaluate credits based on rejection risk
- We think from an assessor’s perspective
What is the Certification Reality Check?
This is an independent feasibility analysis — no obligation to certify.

You know exactly where you stand — and what you should not overpromise.
Do you decide to continue working with me afterwards?
Then part of the Reality Check will be deducted from the follow-up trajectory.
What happens after the Certification Reality Check?
The Certification Reality Check stands fully on its own.
You are not tied to anything.
However, for many clients it forms the natural starting point for next steps.
Based on the outcomes, you can:
- Use the insights internally, without further obligations
- Adjust ambitions before time and budget are committed
- Plan targeted improvement measures towards a next certification round
- Or: move forward in a structured way towards BREEAM In-Use certification
When the Reality Check shows that certification is feasible and logical, most real estate owners choose to continue with Expert Guidance In-Use..
This builds on the same assumptions, risk assessments, and evidence logic — without having to start over.
You remain in control of scope, pace, and ambition at all times.
Trusted by consultants, real estate owners, and project teams
I support BREEAM projects both as an Expert and as an Assessorand regularly collaborate with established consultancies — from individual buildings to complete real estate portfolios.
What clients value in this:
- Independent role as both Expert and Assessor
