Eighty-five years
of weather, in one run.
Build 100% sustainable, exascale-capable data-centre campuses with science-grade software support. Choose where, when and how to cool them.
A 25-year design life starting today must hold for the climate of 2050 — not 2024. CoolingSim is built around that reality.
A data-centre will outlive every climate model it was built against.
Hyperscalers still pick cooling technology from a spreadsheet of typical-meteorological-year averages. We don’t. Every candidate site, every technology, every hour for the last eighty-five years — that’s 36 million-plus simulated hours per brief before a single chiller is specified.
The output is not a recommendation. It’s an evidence file — design PUE, P99 PUE, WUE, capex, lifetime opex, ISO/IEC 30134-2 worksheet — that an EPC can hand to a permitting authority on day one.
One brief in.
425 cooling scenarios out.
Drop coordinates, IT load and a reliability target. CoolingSim returns the full 5-technology × 85-year matrix, ranks by PUE / WUE / opex, and writes the engineering report straight into your handoff package.

Four surfaces. One coherent record of how a campus was designed.
AI Architect
Hand Claude a one-page brief. Get a campus JSON config back — phases, MW, redundancy posture, cooling tech shortlist — ready to drop into a simulation run.
Masterplanner
Drag a 2D footprint, watch the 3D model rebuild itself in Three.js. Halls, substations, set-back zones, and chilled-water loops all stay coordinated.
Engineering report
Every run produces a structured DOCX — KPIs, climate baseline, technology comparison, sensitivity table, sign-off blocks. Permit-grade out of the box.
Auditable by design
No black boxes. Every PUE number links back to the exact ERA5 hour and the exact equipment curve it came from. Reproducible from a single seed.
Brief on Monday. Permit-ready report on Friday.
Brief
Coordinates, IT load, redundancy posture. Optional: paste a customer RFP and let the AI Architect draft the JSON.
Simulate
Five cooling families × 85 years of ERA5 weather × hourly granularity. Roughly 36 M simulated hours per technology per brief.
Report
Structured DOCX with sign-off blocks, KPI matrix, climate baseline and the full sensitivity table. Auditable, exportable, reproducible.
Reports cite their sources. Always.
To get away from the typical greens that are nowadays associated with greenwashing, we treat energy and data as the same substance — light projected into the world. Our accent is the orange of an Earth rising.
