Dear all,

For a specific existing building application, we are looking for a half inch insulating glazing unit, preferably with low-e coating. Based on my research, 5/8" seems to be doable (1/8" glass + 3/8" air gap + 1/8" glass) but I'm yet to find a viable 1/2" solution. Have you come across any on your projects? Thanks for your...

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

Hi All,

At the SCL Summit in November 2019, the Carbon Group discussed meeting in Q1 2019 to craft an action plan for measuring and voluntarily disclosing carbon emissions from our operations.   To kickoff that effort, we will be having an online meeting. 

If your company is already disclosing greenhouse emissions or if that's... Read more

Hello! 

We have several projects that are either pending ILFI Zero Carbon certification or the owner is planning to purchase offsets to cover construction emissions. Thus far, I have not considered this in our corporate footprint reporting. However, we are including A5 emissions whenever feasible and multiplying that performance over the... Read more

Hi Gurus, given these crazy times and many good people being laid off - I'm hoping this is coming at a good time! Hope you are all safe and healthy! It's also flexible so if you are a parent of young child(ren) - also a good 'pandemic job' - sad that that's a "thing" now!

Hi all,

I'm curious if anyone has insight as to the "New Federal Building Performance Standards" that were announced in May of 2021 and then referenced again when E.O. 14057 came out. The memorandum for heads of agencies that was sent out with E.O. 14057 said that the CEQ would issue these standards, but I can't find a commitment to when... Read more

Hi everyone - in doing a carbon footprint for our firm, does anyone know if buildings that we design as Architects considered scope 3 emissions, or are they beyond the boundary of emissions? LMN's buildings, despite best efforts, are cumulatively multiple orders of magnitude above our scope 1 and 2 emissions. We have never included these... Read more
