<summary>* A note on PEPs</summary>

**What is a PEP**\
A PEP (Product Environmental Profile) is a type of Type III Environmental Product Declaration (EPD) specifically tailored for electrical, electronic, and HVAC-R products. As an ISO 14025 compliant document, it provides verified, transparent data on a product's environmental impact—such as carbon footprint—across its entire life cycle.

**Differences between EPDs and PEPs**\
The 2050 Materials data ingestion engine processes both standard Environmental Product Declarations (EPDs) and Product Environmental Profiles (PEPs). Users should be aware of a fundamental difference in how environmental impacts are reported between these formats:

* Construction EPDs: Typically utilise standardised physical units (e.g., kg, m2, m3), allowing for high-confidence normalisation and bulk material comparisons.
* Electrical/Mechanical PEPs: Often utilise performance-based functional units (e.g. "kW per EN14825 over 10 years").

**Technical Impact on Data Processing**\
Due to the highly specific nature of electrical equipment, PEP functional units are frequently custom and non-standardised relative to general construction data. While this specificity ensures engineering accuracy, it limits *comparability*.

To ensure data continuity (in the odd cases where performance-based units cannot be converted to standard physical quantities) our system employs a "per piece" (unit) fallback.&#x20;

For example, when a PEP uses a highly specific custom unit, the functional unit is indicated as the individual product component (per piece of the MEP system). When "piece" is indicated for a product with environmental impact data derived from a PEP, users should verify the specific output to ensure the total impact is scaled with the correct functional unit.
