Water treatment systems often rely on harsh chemicals to treat bacteria, and on high water use from drawdown of water to reduce build-up of concentrates—a process called blowdown.

Hi folks,

USGBC has commissioned this survey of the building industry about Federal tax incentives for building efficiency. They will be sharing results with congressional staff, so this might be a good opportunity to give them feedback from the field!

And it's just 10 minutes.

And, after you do the survey if you want to... Read more

Hello, fellow SDLs, 

I wanted to share an opportunity for you - or those in your network - to join a passionate team of architects and designers based in Anchorage, Alaska. I'm told that you'd be asked to join the full team in Anchorage a few times a year for team building events but otherwise you can WFW (work from wherever!).

Hello Green Gurus,

I am starting some research on municipal incentives offered to developers seeking to achieve sustainability targets and am wondering what you may have come across in your work, including but not limited to achieving Passive House. In my limited research, here are few I have come across to get us started:

How much will it cost to achieve LEED v4 certification?

“We’d love a green building, but can we afford it?”

“We’re required to be LEED Silver, but we’re not sure how to get there under the new rating system.”

“Sure, we’re interested in LEED, as long as it doesn’t cost extra.”

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

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

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

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

Dear SDL'ers

I will be undertaking a two year Master’s degree at the Institute for Resources, Environment and... Read more

Folks, it is with a heavy heart that I write this: Lance Hosey passed away unexpectedly on Friday. 

Many of you know him from the early days of the SDL group, or as an outsized presence at any of the many conferences where we overlap. He's been a list-maker, poll-taker and all around troublemaker in my life for over 20 years; I know I am... Read more
