This question of what equity looks like in project design is one I have been musing on for a while now, and I was excited that several of us were able to talk about it at the SDL Summer Summit earlier this month.  That conversation has prompted me to post here, asking what all of you think equity looks like in project design... with a few...

The 2018 ENR Green Building Survey is due March 16th.  I'm sure you all know the metric they use to evaluate your ranking is solely the revenue from projects pursuing a green building certification in the previous calendar year.  Personally, I think this totally bogus.  How "green" a contractor is may correlate with how much revenue they have...

Chillers are part of larger systems that provide cooling in large commercial buildings.

BuildingGreen-Approved Water Chillers

Hello Green Gurus,

Back at the retreat in March 2021 (does anyone remember back that far?), we formed an Air Quality Working Group with members from SDL, SMEPL, and SCL. Drawing on our collective experience, standards, research, and other resources, we began navigating the murkiness of indoor air quality considerations. We came up with a... Read more

Hi Friends - I'm sure you've started to see news and posts from personal contacts about the shortage of masks, gloves and other PPE for hospital workers. Our company GCI General Contractors is pulling what we can to donate locally.

I'm teaching a LEED GA study group and was rambling on the differences between CIR and precident-setting LEED Interpretation (that gets posted in the addenda library and all). Then I went onto LEED Online and was showing how those are submitted... but can't actually figure out how a LEED Interpretation would be submitted. Has anyone done this... Read more

Hello SDL Network,

I am working with members of the Seattle AIA COTE in planning an event that we are tentatively calling "Pathways to Decarbonization" or maybe "Decarbonization Success Stories".  The idea is for the COTE to identify entitities (school districts, local governments, higher-ed institutions, corporations, etc.) that have...

The agenda is here. It also has the Zoom link (in case... Read more

Hi folks,

I’m sure most of you know Gail Brager, or at least know of her. For those who don’t, she helps run UC Berkeley’s Center for the Built Environment and is a long-time champion of all the things that make buildings work for their occupants. Perhaps most notably, she was a co-author of the Adaptive Thermal Comfort option in ASHRAE... Read more

Typically made from petrochemicals, carpet and its adhesives can offgas. It is also a challenge to recycle them, increasing the chances that it will be incinerated or disposed of in a landfill. Because carpet has a limited lifespan, its life-cycle performance is key.

BuildingGreen recommends modular carpet that demonstrates lower life-... Read more

This data model is at the heart of our Early Phase Integrated Carbon (EPIC) assessment tool. EPIC is a data-driven goal-setting tool for use in the earliest... Read more
