This technical briefing examines how common default design and modeling assumptions compound, how they suppress real-world performance, and why energy models often fail to show the savings teams expect—even when the design is genuinely better.
We’ll cover:
- How standard design and modeling practices multiply equipment capacity, flow, and control minimums
- Why conservative load assumptions propagate downstream into fans, pumps, reheat systems, and geothermal
- How default modeling inputs often understate actual savings, masking real performance
- The long-term operational impact of hidden safety factors on energy use and system behavior
Real-world example
From years of reviewing modeled results against measured data, I consistently see pumps, fans, and even VAV boxes operating above 50% of their design flow for most of the year—even in buildings that appear well designed on paper.
We’ll walk through why this happens, how to avoid accidental oversizing, and how to align design intent, operating behavior, and modeled results so the full savings are both achieved and recognized.
Audience: Engineering managers, principals, and system decision-makers.
