Phases an materials

General

Hello,

It seems like a lot of materials are missing phase like C3, C4, B4 or B6 so the “yellow” warning is popping up quite often with the missing phases.

How do you recommend to work around this? :slight_smile:

Hi Mathias,
In order to follow the danish building regulations those stages need to be included, but not all have it from the data origin. Hence the warning. C3 or C4 might be 0 at an EPD, but that you can still use.
B4 and B6 is either data you gain from the life time of the material or from the operationel energy consumption.

Hope this helps.

Best regards
Mads

So to understand this - i have to type them in manually? if so where do i do that? :slight_smile:

B4 is calculated automatically when you set a life time less than your considerationperiod.
B6 you can type in when you go to edit project in “Operationel Energy Use”. This data is project specific.

So in case some phases still need to be added, how do we go about that?

I have EPD Glasfiberarmeret beton from BB Fiberbeton. Phases C3 and C4 not declared.
I believe I need to calculate C3 and C4 somehow. Not declared does not mean 0 emissions.

What to do?

Suggestion:
Would it be possible to add a feature, that allows us to use generic or industry data for missing phases?

So in @Julian3000’s example

A1-A3: EPD Glasfiberarmeret beton EPD from BB Fiberbeton
B4: EPD Glasfiberarmeret beton EPD from BB Fiberbeton
C3-C4: Oekobaudat or industry EPD for glassfiber concrete
D: Oekobaudat or industry EPD for glassfiber concrete

Also, would it be possible to make a list somewhere, maybe on Insight, that summarizes all construction where an EPD with missing phases has been mapped?
