We are excited to share the REPORT from the 2019 Small Firm SDL Summit held in Las Vegas on June 5th. Take a look and use this forum to post questions and comments that will allow us to engage our new members as we continue the valuable conversations begun at the Summit. As you will read in the introduction, we know that collectively small... Read more

We are looking at installing an aerobic biodigester in a commercial kitchen for an office client that is VERY concerned about zero waste.  Basically, this system takes food waste, treats it with micro-organisms to remove organic matter, and turns it into water of high enough quality to go straight to the sewer.  The manufacturer we are looking...

All,

We are collecting examples of buildings that involved electrification initiatives (building does not need to be all electric as long as largely electric). Please share your projects with us through this short survey. It will take 8-10min to complete.

The study will culminate into a report and best practices to advocate for... Read more

Hi all,

Thanks again to those who presented at the AIA Show & Tell! Here are the slides for some of the fascinating presentations we saw. Please do not share the slides outside of the networks unless they are marked “PUBLIC.”

There may be more to come; if you presented but did not yet provide permission for your slides to be... 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

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

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

We have an increasing number of projects, where the client is coming to us with "net zero" aspirations and plans, some of which don't fit the typical all-electric, grid-tied building that produces 100%+ of its annual energy use on-site.  There include examples like:

1) A (targetd) living building that maximizes on-site production, with... Read more

Hi Green Gurus,

A "fun" take-away from the sustainable MEP Leaders Summit (just ended today):

Inspired by Passive House, we are embarking on a campaign: "Low Load Buildings Are SEXY".

One idea we have is:  what if the AIA design awards set limits on metrics like heating loads to meet basic eligibility?

If you have... Read more

Everyone agreed during last Friday's meeting that we want to call the site BITuser. The question, however, is what domain name should be used.

Whatever domain name is chosen, it will redirect to the actual site URL -- https://bituser.buildinggreen.com (similar to how LEEDuser.com redirects to https://leeduser.buildinggreen.com).
