CBGA-SEQUENCE: Retrofit Sequencing Governance

LinkedIn Post 09: CBGA-SEQUENCE: Retrofit Sequencing Governance

Here's a question for your AI system: If a building needs both LED retrofit and deep retrofit, which does it recommend first?

Most systems answer: LED. It's cheaper. It fits the budget. It shows results quickly.

But that's wrong. Deep retrofit should come first. It's the high-impact intervention. Once scheduled, then—if there's remaining budget—consider shallow alternatives.

CBGA-SEQUENCE enforces this priority through hard constraints. Before recommending any retrofit, the system must:

1. Assess the building for deep retrofit need

2. If deep retrofit is needed, schedule it first

3. Only recommend shallow retrofits if deep retrofit is not feasible

4. If deep retrofit can't be funded, escalate for explicit approval (not silent deferral)

This prevents indefinite deferral. It forces a governance conversation about funding and feasibility, rather than letting the algorithm hide constraints by recommending cheaper alternatives.

The goal isn't to mandate deep retrofit everywhere. It's to make sequencing explicit and force prioritisation based on carbon impact, not cost.
