Championing the
Changemakers

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 all, 

Any Fitwel experts out there? I have a 30,000 sf boutique hotel + spa client who would like to certify under the Fitwel rating system but Fitwel folks are telling me that no scorecard is currently available to hotel clients (can't use mulit-tenant or resi, that a hotel scorecard is under development). Has anyone used Fitwel... 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

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

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. :(

I'm looking to compile an outdoor weather station for a local project, and we'd like to add local outdoor CO2 information to our data. I usually work with Onset HOBO products, but they don't offer an outdoor CO2 sensor. Their weather stations can take data from any CO2 sensor with an analog output - does anyone have any suggestions?

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

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

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

Thanks in advance.

Ventilation fans, kitchen range hoods, and laboratory fume hoods can use significant amounts of energy from both the fan motor and from venting heated/cooled air out of the building—air that then has to be replaced and conditioned by energy-intensive HVAC systems.

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...

Hey, everyone! Many of you on this forum have probably already RSVP'ed but I wanted to put a plug out there for the happy hour event on the evening of November 2nd at our office in San Francisco.

The event is co-hosted by Architecture 2030 and national and local AIA COTE. There will be food, drinks, great people, and a chance to preview... Read more

Hey there SDLs!

We're having a debate in our firm about whether we're at a tipping point to hire an in-house energy modeler - someone capable of doing an MEP-caliber energy model inside a design firm. I know some you have in-house energy modelers on staff and I'd love to hear your experiences:

- How did you know your firm was at a... Read more
