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

Is LEED Online mind-numbingly slow today for anyone else? Or is it just me? I may give up and try again tomorrow. Frustrating as I was hoping to submit a final review today. :(

Here is a fundamental question regarding measuring operational carbon emissions that I'm sure many of you can clarify for me:  Let's say you are considering design options and you want to know the relative contribution of GWP of adding an additional inch of continuous insulation to the building envelope.  The GWP from embodied carbon will...

Hello all,

I need future weather files for a project. We are looking at three years, 2050, 2075, and 2095 using two climate change scenarios, low emissions, and high emissions. I have seen ARUP's Weathershift site that uses RCP 8.5 and RCP 4.5. Are we assuming that 2.6 is not achievable? I would have used this as a low emissions scenario... Read more

The overwhelming majority of wallcoverings are flexible vinyl, laden with all the life-cycle concerns that come with PVC. Products used to contain orthophthalate plasticizers—which make up a large percentage of these products. Phthalates are not bound in the material and can slough off in dust, exposing occupants during everyday work or play.... Read more
