Hi all,

We are looking to study Passive House on a couple small multifamily projects. Our understanding is that WUFI Passive only integrates with SketchUp at this time. Our BIM manager has been trying to find an example of a firm that works in Revit and uses WUFI Passive, to point him in the right direction on workflow. I offered to ask... Read more

Does anyone know of a source for finding the operational solid waste generated by typical building/use types (weight/sf)? I couldn't find anything on LEED, True, or EPA. I found this table but isn't by sq ft for many of hte uses. Waste Generated by Industry and Building Type (wastecare.com)

Hi Leaders,

If your experience was anything like mine, it was a stressful night. I'm feeling a hunger for talking with smart, passionate people about what this all means.

I'm not interested in making this into a political forum--we can all get plenty of that elsewhere. But if you'd like to hang out and just process how you're... Read more

Hello SDL Leaders,

Over the past month, I have been working with ILFI to navigate the question of residuals in LBC compliant products vs. products reporting for a Declare label.

Through our conversations, it came to light that ILFI considers the LBC Red List threshold to be 10,000 ppm, rather than the 100 ppm written into the... Read more

Has anyone had any success with achieving the LEED Building Envelope commissioning points with an alternative compliance path using the requirements of the PHIUS verifier?
