For those of you who have attended the event above, I think you will agree this has been a high quality event.  But DFC is changing the forum this year. Instead of holding an annual event in September, this year they are holding 4 half day events around the country.  Attendance will be limited to 40 people and it is focused on sustainability...

Hello, does anyone have experience with thin film solar? We're looking to add it to a city wide bus station application. Thanks!

Is anyone else working on a project doing Living Building Challenge v4.0 Energy Petal? We're working through the Imperative 08 Net Positive Carbon Resiliency Strategy requirements that ask for the project to be habitable for a week in the event of an emergency. We're curious how others are defining "habitable" and what systems assumptions... Read more

Electrochromic glazing holds the promise of less glare and better energy efficiency with fewer moving parts. The reality is much more complicated and includes information you won’t... Read more

Hi all - has anyone worked on a project with thermal energy storage tank design in the scope?  I'm wondering if anyone has recommendations for specialists or engineers who have experience.  Thanks!

Pint-flush and non-water urinals can save tens of thousands of gallons of potable water per year. A single non-water-using urinal can save more than 10,000 gallons of water per year compared with the U.S. EPA standard of 1.0 gallon per flush (gpf).

When older 3.0 gpf urinals are replaced, the savings can be as great as 50,000 gallons... Read more

Hi all!

I'm working on my first energy positive / passive house multifamily building and trying to figure out the trash/recycling chute. I am curious what solutions you have employed to make the trash chute air tight? We have excluded the whole chute from the envelope. Do you use airtight doors (and which ones?) at each floor trash/... Read more

I read a very misleading article on the AIA's website today regarding antimicrobials and the benefit of microbicidals in paint. It was written by a manufacturer, not a healthcare professional, and was not obviously labeled as sponsored content on the website. (I received the link in an email, which did label it as such).

Happy Friday, SDL!

We're running a Tally WBLCA for an environmental education center, which has a very small floor area but a fairly robust concrete/steel structure. Still, I was surprised to find an intensity of over 1,000 kgCO2/m2 for the building.

This is way higher than the general benchmarks I've found in the CLF's database,... Read more

Hello, All, Is anyone familiar with One Click LCA software and resources?  Similarities/differences from a Tally or Athena approach?  Many thanks!

I'm looking to compare using an electric tower crane vs a diesel generated tower crane.  I've got the average gallons/hour for the size of crane I'm looking at, but when I reached out to the crane manufacturers, they can only tell me what size electric supply I need to provide, not the kWh usage for the cranes.  I know that it varies depending...

Hi folks! Our AIA Seattle Committee on the Environment is hosting a series of decarbonization talks that might be of interest to this group. The next one is coming up next Thursday with the University of Washington.

I am looking for case studies/trying to identify buildings using concrete mixes with upwards of 30% replacement of cement by SCMs.  I've been in conversations with some structural engineers who are interested in lowering embodied carbon in upcoming projects, but would like to see examples of where this level of replacement has been successfully...

Hello Gurus,

I am working with an owner who is making zero-carbon commitments and wants to explore setting carbon budgets in their capital plan (and subsequently their individual projects). We will be starting exploratory discussions next week and I was hoping some of you might have been working with other owners who have already... Read more

Embodied carbon in products and existing buildings. What does LCA tell us about renovation vs. new construction and material choices?
