## Why we are cheaper than consultancies

- **In-house CFD team, no subcontracting** — every project runs through the same KGEP Zephyr engineers; no junior-engineer markup, no overhead transfer.
- **HVAC-niche specialisation** — focused scope means repeatable workflows, faster setup, and lower per-project hours.
- **Flat pricing, no billable-hour inflation** — fixed scope, fixed price; no scope creep on Standard / Fast Delivery tiers.
- **Continuous interchange** — we communicate throughout; no account-management layer, just a direct channel to the engineer running your simulation.

Quality is **not** compromised: ANSYS Fluent 2026 R1 license, ISO 7730 thermal-comfort compliance (PMV / PPD / DR), k-ω SST turbulence modelling, y⁺ ≤ 1.0 boundary-layer mesh quality. Every deliverable is validated against real-world built installations (see the Hospital Operating Block case on the landing page).
