| Project | ISO 5 Cleanroom — Hazardous Exhaust & Process Cooling Renovation |
|---|---|
| Location | Golden, Colorado |
| Owner | National Renewable Energy Laboratory (NREL) |
| Delivery | Mechanical renovation inside an operating ISO 5 cleanroom |
| Completed | September 2025 |
| Systems | Hazardous exhaust for LPCVD tool installation · welded 316 stainless steel ductwork · existing-conditions Revit modeling · prefabrication |
NREL needed a hazardous exhaust system added to support an LPCVD tool installation — inside an ISO 5 cleanroom that had to keep operating. In a critical environment at that classification, there is no room for improvisation: every penetration, every weld, and every hour of downtime has to be planned before anyone touches the space.
ASE built the job around precision up front. The team produced detailed existing-conditions Revit models, prefabricated welded 316 stainless steel ductwork off-site, and sequenced all in-room work through formal Method of Procedure (MOP) activities coordinated with the lab.
The system was installed with downtime limited to the scheduled MOP windows — the cleanroom remained fully functional throughout construction. The project demonstrates the combination that defines ASE's critical-environment work: accurate modeling, prefabrication, disciplined field sequencing, and respect for an operating facility.
