Greetings eco-warriors! Brace yourselves as we dive deep into the riveting world of Environmental Product Declaration (EPD) Verification calculations. Remember, this isn’t your everyday arithmetic, so fasten your mental seatbelts!
EPD = ∑(Wi * Mi)
Where:
EPD
is the Environmental Product DeclarationWi
is the weight of the i-th material in poundsMi
is the multiplier for the i-th material
