Championing the
Changemakers

Greetings, Green Gurus:

As unbelievable as it sounds, the Environmental PROTECTION Agency has launched a PR blitz in support of their "new use rule" on asbestos. So the BuildingGreen community needs to push back harder. I'm reposting the links to the letter of opposition that Mary Ann Lazarus put up last week. We definitely need more... Read more

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 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

Good daylighting intentions can end up increasing glare and solar heat gain.

BuidlingGreen-Approved Lightshelves

We look for lightshelves designed to reflect direct sunlight onto the ceiling, turning what could potentially be glare into diffuse, ambient daylight that penetrates deep into the interior of a building.

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. :(

Hello Green Gurus,

A close colleague of ours, Frances Yang of Arup, is distributing a survey developed in partnership with the Healthy Building Network (HBN).

The survey asks for which product categories you need more health information. Answers will help inform which product categories HBN next incorporates into its HomeFree and... Read more

Hello all, 

Wondering if anyone has experience with lead limits in electrical cable and wiring? 

LEED for Healthcare allows a limit of 300 ppm of lead in electrical wire and cabling - my search for compliant products has been all dead ends. (MRc PBT Source Reduction - lead, cadmium, and copper)

Acceptable regulations for... Read more

Does anyone know where one can locate weather files (EPW) that has predicted future data for climate change?

Thanks in advance.

Under a high carbon scenario, most of North America will be 2 degrees C hotter by 2050. Meantime, we're designing buildings that will still be around in 2050, to codes that don't yet factor in chronic risks associated with climate change. I want to explain these risks to my colleagues; I'm hoping some of our green gurus can help answer the... Read more

Hello Sustainable Construction Leaders,

It's come to our attention that although we shared the slides from last fall's all-network Show & Tell in Atlanta, we neglected to include the presentations from the SCL Summit itself. Since we believe in "better late than never," here they are!

As a reminder: we have permission from... Read more

Has anyone used a commercial heat pump water heater for a large protect?  I have found a few manufacturers for this technology, but want to make sure this is a viable and cost approach to electrical eliminate gas on a path to all electric.

Hi All,

Has anyone successfully adopted a Revit to ClimateStudio workflow with their new export tool? Right now we are using cove.tool because it works reasonably well with iterative Revit modeling, but are itching to try a more accurate and nuanced alternative.

Thanks for any and all experiences!
