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...

See you all then.

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

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)

Hi All,

How are folks funding training for your employees? Would it help to have free training opportunities besides lunch and learns or ones you do yourself?

For those of you outside of Massachusetts you may have employees or friends in MA that this could be relevant to.  I'm hoping my friends in MA have already heard this.

Concrete and other cementitious materials have both environmental advantages and disadvantages. As builders and designers, should we be looking for alternatives or embracing concrete over competing materials?

This special report takes a look at how these materials are made, presents the key environmental considerations relating to their... Read more

There has been some great press in the last couple of days related to Healthy Building Network's (HBN) newly released report "Chlorine & Building Materials Project".  That report is over 200 pages long, but there is some great commentary available that makes the top issues much quicker to grasp.

Chlorine is used to make PVC and PVC... Read more

There seem to be three main options: wood, composition siding, or fiber cement siding. I am looking for something with low embodied carbon, little maintenance,... Read more

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...
