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.

Does adding solar panels reduce a building's EUI?

Existing operational use of a building is 80 kBtu/sf/year. When we add solar, it will change the source of energy but does not change the usage.

My understanding is that the EUI does not change, but it would be good to hear from others.

It's energy consumption at the point... Read more

Hi All - as Environmental, Social and Governance (ESG) becomes increasingly prevalent, I'm trying to learn more about what types of requests for ESG-related information folks are actually receiving and what types of trainings on ESG would be most helpful.  Drilling down a bit, I'm curious as to how ESG data points are moving down the supply...

Is there a list of which number corresponds with each Best Practice? E.g. "03 Energy Audit & Planning."

Welcome to the quiz portion of Full-Blown Energy Modeling.

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


1. Explain the role of the energy modeler and how each energy model opens an informed discussion between the entire project team about the interactions between architectural and... Read more

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

Does anyone have experience pursing SITES certification on an essentially a zero-lot line project?

We are required to achieve silver certification, but the project scope/phasing recently changed and the entire site/parking area was eliminated and we no longer have a green roof. It still appears we can meet silver certification as so few... Read more

Keith Hempel, Julie Hiromoto, and Billie Faircloth have been elevated to the AIA College of Fellows - I'm sure I'm missing others but congratulations! Can't wait to celebrate in person - I still rememer Lance Hosey in his tux and Beth Heider in a full ball gown at the AIA Fellows dinner in Chicago (the only one I ever attended. . .) 

Following up something I mentioned at the summit - the EPA is hosting public comment webinars related to the IRA and construction. The first one seems particularly relevant, 3/2/23 from 2-3.30pm EST “Reducing Embodied GHG Emissions: Construction Materials Prioritization and Environmental Data Improvement”. Good opportunity to have our voices... Read more

For my first test post I'm going to be completely boring and ask about logistics.

If we know of someone that should be part of this forum, how do we invite them? There were a couple of people that I thought were on the Wiggio who I recently found out were not. There may also be folks from our regional groups who may not have been part... Read more

What is the lag time for historical embodied carbon data catching up with real-time information as manufacturers source renewable energy? Is our professional time best spent calculating with out-of-date information or more simply calling for manufacturers' elimination of fossil fuel combustion in their production and transportation of materials...

Metal roofs can also provide high solar reflectance, minimizing a building’s contribution to the urban heat island effect. 

BuildingGreen-approved

Materials and finishes recognized by Energy Star maintain solar reflectance levels after three years of use of 50% for low-slope and 15% for steep-slope. Some unpainted metals and many... Read more

Hi Sages,

As you may have seen in my message, the Peer Networks Member List is not very helpful to us (yet), because a person can only show up in one network. Many of us are also in SDL or other networks; there are many more of us than show up when you filter that list for "Sages."

Until we can get that fixed, we'll share the... Read more

Does anyone subscribe to Green Badger? Do you find it valuable?

Hello Gurus,

I’m writing to share with you an effort a small group of lighting designers from the Boston area started which is now rolling into a large scale effort.  We’ve put together a Lighting Advocacy Letter to accelerate the sustainability of lighting products. Inspired by the AIA Materials Pledge, the letter is intended to... Read more
