We have an MEP engineer that is calculating peak loads at about 6 times passive house levels on a large commercial building that is at or near passive house levels of insulation and air infiltration. We suspect one reason is that he is figuring a 50% efficiency level for the ERV. We are showing him ERV systems with 80-90% efficiency, but they... Read more

Welcome to the quiz portion of Can Concrete Save Us? Locking Up Carbon in Building Materials

Learning Objectives
Upon completing this course, participants will be able to:


1. Explain current strategies of carbon capture and sequestration (CCS).
2. Detail how concrete offers another possible pathway to... Read more

Tomorrow is my last day at FXCollaborative before I head back to school. It has been such a gift to engage with you all over the past 10 years. Please stay in touch - my contact information is [email protected]. I am headed out to UBC next week to do a deep dive into resilience and adaptation in urban environments.

Hi everyone,

I’d like to invite you to join this Friday’s webinar hosted by the Embodied Carbon Network: Using Whole Building LCA to Reduce Embodied Carbon within LEED and Beyond, and to follow up with a tool that I presented at this summer’s Architecture SDL summit, which ZGF has now upgraded and made free to the industry at large....

On a large sports project, we worked with the structural engineer to spec low carbon / high SCM concrete mixes. Much of the floor area will be sealed and polished concrete, and a concrete sub is pushing back on the SCMs saying they should not be above 20% (with a preference for 0%) for the polish to finish properly, per the manufacturer. Anyone... Read more

Hello Everyone,

Here is the 2019 SCL Demographics Report, thank you to everyone who submitted responses. Enjoy!

The SCL Salary Survey Report will be coming next and please note that the Salary Survey is only distributed to those who participated.

All the best,

All,

Some of my colleagues and I have been working to promote interest in mass timber construction for K-12 builidngs.  As part of that effort we redesigned a large high school using mass timber in lieu steel, and conducted a whole building life cycel assessment to measure the reduction in embodied carbon.  We also conducted a program-...

Hey Peer Network! Curious, if we can crowd-source a solution here for the pervious pavers at our Omaha office (climate zone 5A). Apparently over the years we've tried to add different kinds of fill here (gravel) but it keeps... disappearing. Any recommendations with either a replacement product or fill item? 

Green Gurus,

Taking advantage of the good stuff that this pandemic is leaving us with, the Boston COTE has gone virtual for its meetings. That means that all of you around the country can join our great program.

Coming up next Wednesday at 2pm EDT (11am PDT, 1pm CDT) we'll have the always inspiring Andrea Love present along with... Read more

All,

I'm looking for a quick methodology to estimate GHG emissions from refrigerants on a per SF basis. Are there any benchmark studies or quick calculators similar to the embodied carbon study? https://carbonleadershipforum.org/embodied-carbon-benchmark-study-1/

Thanks,

Josh

Hi folks -

I was contacted last week by the producer of the documentary that launches this Thursday, 12/10 - he is hoping to generate interest among folks across the environmental spectrum (which of course includes all of us!) so I am sharing his pitch below with you all. The subject of water scarcity and drought is only going to... Read more

Hello,

We’re looking for Design Energy Code Equivalents for Chinese commercial energy codes. Do any of you have  any good sources? I’ve only found data comparing ASHRAE 90.1 2013 to the Chinese Code at that time. We understand the Chinese code require a 65-75% energy savings over the baseline but don’t have good information for defining... Read more

The opportunity for water savings from installing efficient toilets, and from toilet replacement, is significant. In addition to improvements to the traditional gravity system, pressure- and vacuum-assisted flushing systems are available that offer superior performance—albeit often with some increase in flushing noise.

For those of you that don't know me, I'm the Director of Sustainability at the Structure Tone organization. Betting that you can guess what my role entails since you're all in similar roles and we've done the introductions a couple of times in different forums...given that I'd like to introduce myself personally.

I live in a suburb of... Read more

Does anyone have any comparative analysis/reviews of the various energy modeling protocols that includes the 'new' Trane TRACE interface?

Thanks!
