Energy Performance Models
Energy performance models are predictive models that forecast an asset’s energy consumption, efficiency degradation and CO2 emissions over time, so energy and carbon trajectories can be planned alongside cost and risk in the same investment scenario. Rather than tracking sustainability separately from capital planning, they let asset owners weigh a retrofit’s energy savings against its cost the same way they would weigh a structural repair.
How energy performance models work
These models are calibrated to specific asset families — HVAC systems, building envelopes, industrial equipment, grid infrastructure — using historical performance data and engineering knowledge of how efficiency degrades with age and use. They forecast how an asset’s energy consumption and emissions will evolve under different scenarios, from business-as-usual to a targeted retrofit or full replacement, producing comparable cost, carbon and performance projections for each option.
Why it matters for asset-intensive organisations
Decarbonisation targets increasingly have to coexist with reliability, affordability and regulatory deadlines — EPBD renovation milestones, CSRD reporting, national energy codes — rather than being pursued as a separate initiative. Without energy performance models embedded directly in the investment plan, sustainability targets get modelled in a separate spreadsheet from the CAPEX plan, and the two rarely reconcile cleanly under budget pressure. Embedding energy and carbon data into the same scenario engine as cost and risk means a retrofit’s energy-efficiency case is evaluated on the same defensible basis as any other investment.
Energy performance modelling with Simeo
Oxand Simeo™ includes 1,300+ energy performance models covering buildings, infrastructure, social housing and healthcare facilities. These models bring energy and CO2 data into the same investment scenarios as cost and risk, so decarbonisation pathways can be compared against, and combined with, structural and mechanical investment options, and exported as audit-ready reports aligned with EPBD and CSRD requirements.
Frequently asked questions
Are energy performance models only relevant to net-zero or ESG teams?
No. Because they sit inside the same investment scenario as structural and mechanical cost and risk models, they inform decisions for facility and asset managers, finance teams and executives, not only sustainability specialists. See sustainability and ESG asset planning for how these roles use the same models differently.
How is an energy performance model different from an energy audit?
An energy audit is typically a point-in-time assessment of a single building’s current efficiency. Energy performance models are predictive and comparative: they forecast how efficiency and emissions evolve over years under different investment scenarios, across an entire portfolio.
