MERV-13 is a good way to get most benefits without a huge cost.

A couple questions for this group. I know we're having a Green Commons meeting on this next week. But can anyone comment on the following questions?

-Have you or your firm split the benefit of the 179D with a client? Is this typical?

-Is prevailing wage a requirement for all 179D benefit, or does it follow the same lines as... Read more

We are working on a large healthcare project in Minnesota.  We're setting sustainability goals a bit late - no certification, but targets with accountability.  I'm working to determine recycled steel content (for structural steel and rebar), and I've gotten a bit of push-back on recycled content based on being in the region of the Iron Range...

AND/OR: if any of you have attended in the past - was it... Read more

Though BuildingGreen has long supported the use of electric hand dryers as a more environmentally friendly hand drying option, the majority of evidence appears to support paper towels as a preferred method of controlling the spread of potential pathogens. 

And even the most efficient hand dryers contribute significant CO2 to the... Read more

The AIA conference is coming up soon as well.  It is scheduled for June 19-23 in NYC. I have heard about a lot of great sessions and I am thinking it would be helpful if we could collect info here.  Please respond to this message with info about your session and I will compile all of this into a handy reference document.  I will start with my...

Hi Green Commons,

It’s been eerily quiet here since Tuesday night. I’ve been quiet mostly because I just didn’t know what to say. The election results are certainly a blow to pretty much everything we’ve been working for. There is so much we don’t know about things might play out, but I’m feeling a range of emotions ranging from... Read more

Dear Gurus,

At Greenbuild this year I'll be discussing how statistics can lie (in the context of green building claims).  I'm collecting examples of this to prepare.  If any of you know of examples, please send them to me! 

Here are a few of the fun ways statistics might lie that I would be looking for: biased or too-small sample... Read more

I'm wondering if people are seeing any increase in WELL or Fitwel certification interest? Or any other 3rd party systems aimed at health and wellness? WELL seems like a higher bar and now WELL v2 offers more flexibility. Is interest and adoption of 3rd party health and wellness certs growing? 

I am looking at having staff members take a materials course and deciding between Parsons Healthier Materials and AIA Materials Matter certificate programs. Does anyone have feedback on either? Bonus points if you know about both and can provide a direct comparison. Thanks!

I am looking for examples of adaptive reuse projects that have addressed current or future flooding by elevating floors from the existing condition.

In trying to help a client write a case study on avoided carbon by using slag and flyash, I am having trouble finding a one for one equivalency that can be verified.

I have found for one pound of flyash, one pound of carbon is saved - but I can't verify that.

Appreciate the feedback!

All - 

We have corporate clients that are starting to request antimicrobials in response to Covid-19. I assume we are not the only ones seeing an increase in these requests. Knowing that the evidence supporting antimicrobials has limited to no efficacy, how are you approaching these conversations? We want to continue to advise based on... Read more
