Championing the
Changemakers

Hi Green Commons,

It’s been eerily quiet here since Tuesday night. I’ve been quiet mostly because I just didn’t know what to say. The election results are certainly a blow to pretty much everything we’ve been working for. There is so much we don’t know about things might play out, but I’m feeling a range of emotions ranging from... Read more

Was anyone else surprised to see ASHRAE 228-2023 using eGRID Subregions for both the Regional Electricity Source Energy Conversion Factor and Regional Electricity Greenhouse Gas Emission Factors? In the past I have used eGRID sub-regions but also State and local utility conversion factors depending on what energy or operational carbon story I... Read more

Fellow Sages,

I was at an interesting lecture last night. Phil Bernstein (formerly of Autodesk, now at Yale) was speaking (in Lawrence, Kansas, at the U of Kansas) about AI and design/AEC ... you may know that he authored the 2022 book, Machine Learning, about AI and the AEC field. 

Phil has a very interesting posture about AI... Read more

Hi - We have some projects within reasonable reach of ILFI's Zero Carbon Certification, which will require purchasing some off-site renewable energy. As a State Building Code Council member, I'm also eyeing the Zero Code which we will seriously consider in the next 12 months; this also requires a purchase of off-site renewable energy. 

I... Read more

Dear all,

A mechanical engineer on a healthcare project we are working on has asked for help in dividing the ventilation calculations between ASHRAE Standards 170 and 62.1; can anyone here help shed some light on it?

"This is the first time I am working on LEED for a hospital and I am not sure how the template wants me to show... Read more

Hi Gang, 

We are looking to implement the contractor commitment and are running into COVID-19 protocol barriers when looking at the Jobsite Wellness category specific to the soap as well as the food storage/eating areas on site. Anyone else run into this issue?

I have a colleague (lawyer) who is trying to assemble a list of precedent projects that used penalties or incentives for achieving energy targets. The topic she is addressing is how contracts may be changed to address growing climate change concerns.

At the moment, the only concrete example she has is a project in Washington by the US... Read more

This would be a great place to share insights and reflections from the opening session. 

Hello! i had in my notes that the group interested in jobsite wellness was going to schedule a call mid-January.  I don't remember who was leading the effort.  does anyone have a list of who is on what committee?

thanks!

Has anyone seen a comparison between IECC 2021 and previous versions of the energy code, including ASHRAE 2010? I'm curious how far ahead code buildings are relative to LEED v4.0, and how much the latest IECC raises the bar relative to the previous. I did a quick search for the LBNL and other studies that look at this, but didn't see anything... Read more

We are working on a large healthcare project in Minnesota.  We're setting sustainability goals a bit late - no certification, but targets with accountability.  I'm working to determine recycled steel content (for structural steel and rebar), and I've gotten a bit of push-back on recycled content based on being in the region of the Iron Range...

Evaporative coolers use far less electricity than conventional refrigerant-cycle air conditioners and they operate without the use of refrigerants, both features that make them attractive for green buildings. However, their suitability is limited to drier climates, and most products use significant quantities of water.

I am still basking in the afterglow of this week's summit, and getting ready to share nuggets of wisdom with my colleagues at our all-staff next week. I was so immersed in the moment that documenting the outlines and choices presented for breakouts slipped my mind. Is there somewhere to access these slides to refresh my memory?

Thanks... Read more
