Influence over performance is highest at concept and lowest at handover, while the cost of change moves in the opposite direction. Our scope is arranged around that reality.
1
Concept
Targets, rating selection, feasibility, massing and orientation response, early carbon and cost baselines.
2
Design
Energy and daylight modelling, façade optimization, LCA, LCC, credit strategy and design-stage evidence.
3
Procurement
Specification review, EPD and submittal assessment, tender sustainability requirements.
4
Construction
Contractor coordination, site audits, record collection, compliance verification, submission.
5
Operation
Performance verification, GHG inventory, ESG reporting, recertification and continuous improvement.

Our position
Sustainability consultants are frequently appointed once the design is fixed, at
which point the role reduces to documenting whatever the building already is.
Appointed at concept, the same fee changes the building. We would rather argue about
orientation and structural grid than write a compliance report for decisions nobody
can revisit.
