When should you use a generic value instead of a specific EPD?
Purpose
Section titled “Purpose”Decide when a generic value is the right choice, instead of a specific EPD.
Prerequisites
Section titled “Prerequisites”You’ve found several possible data sources for the same building product in the library.
- If a specific EPD exists for the exact product actually used in the building, always use it. It’s the most accurate.
- If it hasn’t been decided exactly which product will be used yet (e.g. early in the project), use a generic value as a conservative, product-neutral estimate.
- Update to the specific EPD as soon as the product choice is final.
Result
Section titled “Result”Early phases of the project can keep calculating without being locked to a specific product, while later phases become more accurate as choices are made.
A generic value isn’t a shortcut you fall back on to “improve” a result. It’s a conservative starting point, not a lower estimate.
