Hi friends,

As you might have seen from my op ed last week on BuildingGreen.com, I’m convinced that just voting is not enough; we all need to do all we can to improve our chances of success in this election. My wife Janice and I have been writing get-out-the-vote letters using Vote Forward as our platform. I thought it might be fun, and... Read more

I was recently asked if there is a way to quantify financially what one MT eCO2 might be worth in the context of a building owner reducing their own carbon emissions.  How do you put a dollar value on those reductions?  Does anyone have experience with that or can you point me to the correct resource to answer this question?

It was great to see everyone who was able to join in the peer networks webinar and to be able to share a brief update on what the Defining and Measuring Resilient Outcomes working group has accomplished over the last year... and what we are looking forward to tackling in the coming year. 

I've both attached a copy of the deck here and... Read more

The Project StaSIO competition is in full swing, and its time to rate the submissions that made it to the public voting round!  Fancy yourself a connoisseur of simulation graphics and have a spare 5-10 minutes this Friday?  Take a browse through the gallery and rate the 10 graphics and 4 case studies that made it to the final round! Winners... Read more

As announced in last week's SDL/SCL Winter Summit, I have been working with a group of regional AEC professionals, industry stakeholders, and the New Buildings Institute on two code proposals to the 2021 Seattle Building Code that limit the Global Warming Potential (GWP) of concrete & steel in buildings over 50,000 sf (see attached).  We ...

Hi all!

A couple years ago now there was an incredible thread here about circadian lighting design and WELL. There was a lot of dipping toes in the water with intent to gather lessons learned and report back.

What have been the high points and low points of circadian lighting design so far? What seems cost-effective and worth... Read more

Hello All,

A group of us (three architects and a builder- sounds like there should be a joke here) were debating this and we  are stumped.

Application: Residential exterior trim.

50 year warrantied composite product of agricultural byproduct with PVC (EPD not published yet) vs 100 year (if primed on all sides and painted or... Read more

Hi,

I have a colleague doing research on PCM in several projects. For context in their report, they were wondering if this group has seen any recent increase in application of PCMs in recent years. Is it just in ceilings or other applications? If so, what products are being used? They were having difficulty finding manufacturers other... Read more

I'm looking to draft some one-page briefs for my consulting engineers to outline what we would like to see in their specs regarding certain materials and systems. For example, letting the plumbing and civil engineers know that we prefer to eliminate PVC pipe and want them to specify alternatives like Polypropylene, cast iron, ABS, etc. The idea... Read more

Hello SDL Leaders,

Over the past month, I have been working with ILFI to navigate the question of residuals in LBC compliant products vs. products reporting for a Declare label.

Through our conversations, it came to light that ILFI considers the LBC Red List threshold to be 10,000 ppm, rather than the 100 ppm written into the... Read more

Attached are the raw notes from the Design Process Conversations.

And here are the Guiding Questions from the Agenda Survey:

Design Process: how to intervene to get better outcomes?

How do I crack the nut of making a difference within my firm in the Design Process?

What strategies alter our fast-paced design... Read more

Does anyone here have a draft spec for low embodied carbon concrete they could share? I see the GSA has a standards sheet with MGWP limits, but we are hoping to actually specify the mix for upcoming projects.

I have been watching LEED Zero for a while, and have appreciated certain things, but one thing I think is an absolute disaster is their allowance of mainline RECs for claiming Zero Energy and Zero Carbon performance.  I just asked this question on the LEED Zero webinar, and the panelist basically said, "it's part of LEED Zero, therefore it is...
