Has anyone had a Contractor track GHG emissions during construction? If so, any advice on how to include that in the project specifications?

Thanks!

Columbia already offers access to free EV charging for our field employees. Of the few projects that have have opted in so far, we've had to custom design and intall EV charging setups. It's good that we're doing this, but it won't scale quickly enough and cost effectively.  I think a practical next step is working with trailer companies so... Read more

I have been watching LEED Zero for a while, and have appreciated certain things, but one thing I think is an absolute disaster is their allowance of mainline RECs for claiming Zero Energy and Zero Carbon performance.  I just asked this question on the LEED Zero webinar, and the panelist basically said, "it's part of LEED Zero, therefore it is...

Hi Gurus!

I'm desperately seeking any case studies (past/currently on the boards) of labs that have been designed without natural gas infrastructure (the topic I have to debate is about commercial spec labs but any lab case study, wet or dry, is welcomed). This is for a development authority that will be setting guidelines for new... Read more

Hi all,

We are about to start a affordable housing passive house project in Boston and in a few presentations I've seen great signs that builders use to try to get the point across to subs as to how important air sealing is. Some are even quite funny! The builder we are working with does not have a sign like this, but is open to ideas.... Read more

You’ve probably heard that wood products are carbon neutral. You might also have heard that timber harvesting causes immense carbon emissions.

Which is it?

Could it be both?

Shane, please confirm that there is a meeting this Friday (4/6) and if the time is 3:00 ET. We plan to have at least one member from our team there. Also, please forward the links/numbers for joining the meeting.

It would be helpful to know any questions you have ahead of time (if possible) so we can bring answers and what portion of... Read more

Does anyone have an experience on recycling/reusing architectural glazing? We have a sizable glazing replacement project, and I am realizing how difficult it is to find a way to prevent the glazing from going into the landfill. So far, I have reached out to Terrazzo (aggregate) manufacturers, Glass Recycling Coalition, Architectural Glass... Read more

Vapor retarders are meant to protect our building assemblies from getting wet, but they can also slow drying, contributing to mold and structural degradation.

Hi SCL, 

Just thought I would share an interesting piece from Construction Dive about a lack of guidance on when to halt work due to bad air quality--from wildfires or otherwise. A few SCL companies are mentioned here as having their own policies, but I was pretty shocked to learn that this isn't required by OSHA.

If you are in the LA area please come! The 11th includes an outdoor reception at the center after the presentations. It’s also an... Read more

I was wondering if any design or contractor friend here can kindly share the carbon emission factor of excavation during construction. 

I found a paper that provides energy use rate per cubic meter and associated carbon emission in kgCO2 for different phase of construction such as excavation earth work, pouring and lifting concrete,... Read more

Hive mind,

We recently learned that 3M has discontinued the production of their 3M Daylight Redirecting Film (https://www.3m.com/3M/en_US/building-window-solutions-us/solutions/dayli...). This product was selected by an architecture client last year as the optimal daylight/glare control strategy for a school project, and we're assisting... Read more
