There are 2 gases that I believe should be updated into the eTool library:
– A relatively recent gas on the market is HFO-1233zd(E). There isn’t really a similar gas in the library currently that I could use as proxy (GWP is low but not zero; and 0 ODP impact)
– R134a should likely be updated with a 0 ODP impact.

Similarly, R454B or also known as XL41. This is becoming a replacement for R410A however it has a much lower GWP. Does anyone know why we can’t enter or create our own refrigerants?
Hi Oscar, if you have an EPD for the refrigerants, you can most certainly add your own into eTool.
