Physics-Verified Building Energy Simulation Software for Faster Decisions

For MEP engineers, architects, energy modellers and consultants: run load calculations, climate-driven simulations and retrofit scenarios in one platform — with standards, equipment sizing, ROI and client-ready reports attached to the same evidence base.

Most simulation workflows fragment across load tools, spreadsheets and report documents, so results drift out of sync with design decisions. A single deterministic engine with recorded provenance removes the reconciliation work and makes every output defensible.

What the analysis covers

Load calculations

Heating, cooling, ventilation and hot-water loads from deterministic physics engines, zone by zone.

Climate data

Location-specific weather and TMY data drive the simulation — not generic climate assumptions.

Scenario modelling

Compare design options, retrofit packages and operating strategies on identical baselines.

Standards alignment

Calculations referenced to CIBSE, ASHRAE and regional codes, with a standards database spanning 195 countries.

Equipment sizing

Plant and terminal sizing derived from calculated loads, connected to product data.

ROI & reporting

Capex, payback and lifecycle cost joined to the engineering, exported as client-ready reports.

What you upload

  • Building geometry, drawings or basic dimensions
  • Location and use-type details
  • Existing loads, schedules or BMS data if available

What you receive

  • Zone-level load calculations with method references
  • Scenario comparisons on a common baseline
  • Equipment sizing outputs connected to loads
  • Client-ready reports with full provenance

Turnaround is rapid and depends on the completeness of the data you share.

See a real output first

Every figure in an Intelli-BuildAI report links back to its input evidence and the standard it was calculated against. Review a sample before you share any data.

Transparent methodology

Outputs are produced by deterministic, physics-based calculation engines referenced to published standards, with data provenance recorded per input. Where inputs are incomplete, results are clearly marked indicative pending validation — no figure is presented as verified until the underlying evidence supports it.

Frequently asked questions

How is this different from traditional simulation tools?

The simulation engine is joined to standards, equipment selection, costing and reporting in one evidence base — so results flow into decisions without re-keying, and every figure retains its provenance.

Is the engine deterministic or AI-generated?

Load and energy calculations are deterministic and physics-based, validated against published test cases. AI assists with document ingestion and drafting — it never generates the numbers.

Which regions and codes are covered?

The standards database spans 195 countries, including CIBSE and UK Building Regulations, ASHRAE and US codes, and GCC frameworks such as Estidama and Mostadam.

Can I validate the results?

Yes. A published validation register shows engine test-case results, and every calculation exposes its inputs, method and standard reference.
