Hi everyone,

It was so wonderful to meet some of you last month and experience the whirlwind of a summit! I hope you've enjoyed looking over the Summit Report and the flip chart notes, and they've helped bring some order to the vast amount of material we covered. Here's one more piece for you - slides from the 5-minute presentations.... 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.

I'm working with a project team that is looking into bird control options to prevent nesting/roosting/pooping on the scrim that is designed to scrim their building's facade.  They are looking at electrified tape, repellents, laser systems, etc -- Options that don't dramatically impact the building design.  The products they're looking at claim...

A couple Minnesota cities are considering adding electrification to their sustainable building policy (required for new construction receiving City financial assistance). Concerned that the market isn't ready for a full-on mandate, they are considering a more moderate approach of requiring developers/design teams to conduct an electrification... Read more

We should probably agree on the correct spelling for what we at BuildingGreen are calling "BITuser." I noticed that on the Salesforce portfolio screenshot provided by Dennis, it's spelled "BIT User."

BITuser has the advantage of more closely resembling LEEDuser, but it has the disadvantage of looking a little weird in all-caps, as in... Read more

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

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

Thanks in advance.

Hi All, I was initially reluctant to share this, but I've seen similar posts and I think it's in line with our mission and interests so I'll go ahead with it.

Tomorrow 12/9 at 1 PM EST I'm moderating a panel of industry leaders in public health (as it pertains to buildings), construction finance, and project development to review the... Read more

We have a client who is asking us to design a roughly 10 ksf Wellness Center for PHIUS 2021 certification.  The program includes several high density assembly type spaces - roughly 300 person peak occupant load for the building.  The Criteria Calculator that the architect showed us puts the building peak cooling load at 4 BTUH/sf (3000 sf/ton...

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

BuildingGreen Approved, like its predecessor, GreenSpec, is an independent product evaluation service for BuildingGreen members. We offer an unbiased look at products: BuildingGreen does not accept any manufacturer fees for our evaluations. Here’s a quick tour of the platform and how to use it.

Hello fellow sustainable design leaders! I am about to kick off an intensive effort here at EHDD to refine our internal standards for materials. We will be considering both GWP as well as the health of materials (avoiding harmful chemicals). In addition to setting the standards, I will be working to develop a process to vet materials before... Read more
