Reconcile energy bills with a fabric/systems audit to produce a calibrated EUI baseline.
A building energy baseline is built by reconciling a top-down read of metered energy bills with a bottom-up audit of fabric and systems, producing a calibrated energy-use-intensity figure. This grounded baseline makes retrofit option appraisal and net-zero pathway costing far more reliable than modelling alone.
A calibrated energy-use-intensity baseline closes the gap between what a building is modelled to consume and what it actually bills — by reconciling metered consumption data against a fabric and systems audit, you get a single grounded figure rather than two irreconcilable numbers. The method is conceptually mature and widely endorsed in retrofit guidance, but no evidenced case sits on this record, so claims about the reliability improvement it delivers over modelling alone remain asserted rather than demonstrated at scale. Its value for a design team is as a precondition rather than an intervention: without it, retrofit option appraisal and net-zero pathway costing are built on assumptions that can be fifty percent wrong, and interventions are sized against fiction. The practical constraint is access — metered data requires landlord or client cooperation, sub-metering is often absent, and the audit quality depends on what can actually be inspected rather than what the as-built drawings claim. Treat this as a foundational process step on any deep-retrofit project, not as an innovation to evaluate for adoption risk; the risk of skipping it is greater than the risk of doing it.
