Findings Overview

Patterns observed across the cohort, anonymized.

Status: Findings are added to this page as each facility model in the cohort is completed. Per-facility visualizations are not published here; they are shared on request with the named MEP firm of record for each building.

CFD visualization of multiple thermal plumes rising from a generator yard with vertical exhaust columns — Representative result: thermal plume isosurfaces above a generator yard during emergency operation. Vertical exhaust columns from individual units coalesce downwind and lift toward roof level under low-to-moderate wind. (Figure from a representative facility; per-facility figures are not published.)

What we look at

Each facility is evaluated for four exterior thermal phenomena under the same set of wind and operating cases: (1) interaction between generator radiator plumes and adjacent generator-unit intakes inside the yard; (2) entrainment of generator stack and radiator plumes into rooftop heat-rejection equipment intakes; (3) re-ingestion of rooftop discharge into adjacent rooftop equipment under low-wind buoyancy-dominated conditions; (4) outside-air handler intake exposure to either plume family.

Emerging patterns

As the cohort progresses, patterns will be summarized here in anonymized form — for example, how generator-yard orientation relative to the prevailing summer wind correlates with rooftop intake exposure, or how rooftop equipment density correlates with self-re-ingestion under calm conditions. The intent is to surface descriptive observations across the population, not to evaluate any individual design.

CFD visualization showing rooftop plume isosurfaces lofting off a multi-row data center building — Representative result: rooftop heat-rejection plumes lofting off a multi-row data center under moderate cross-wind. Plume tilt and re-entrainment depend on wind direction relative to the long axis of the building.
