Operational Performance & Retrofit Strategy

Performance gap diagnosis, calibrated digital twins, and costed retrofit pathways for existing buildings and portfolios.

We turn metered data into a costed retrofit plan with clear ROI for every intervention

How We Work

Calibrated digital twins from metered data, testing retrofit scenarios with quantified ROI and carbon savings.

01
Audit & baseline

Conduct ASHRAE Level 1 or 2 energy audit and establish the current performance baseline from metered data.

02
Digital twin

Build a calibrated energy model using TM54 methodology until it matches actual performance within ±5%.

03
Scenario testing

Test multiple retrofit packages and rank by energy reduction, carbon impact, cost, and payback period.

04
Investment pathway

Deliver a sequenced decarbonisation plan aligned to CRREM trajectories with clear ROI projections.
