@Vaclav I’m not familiar w/ Kieran Timberlake’s LCA initiative. Can you share a link? I am familiar w/ @chris1 /Endeavor Center’s Book Making Better Buildings, which is extremely comprehensive and IS a tool that applies across all climates.
I think a comprehensive/US-wide tool is just bigger than I have bandwidth for: I could imagine an app that you could put your project criteria into & it would spit out the choices & their implications. I personally am pretty good w/ spreadsheets, so gonna start there! As archaic as it might seem!
Regarding gathering assemblies: My region has a relatively limited selection of common/available assemblies so it should not be that hard to identify them. The key is common/available. But: I do like the idea of sending out a survey to local builders and architects as a way to engage & empower them! Thank you for the input! I’ll keep posting here & if you have any further suggestions/feedback, would be awesome!
