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

We're looking to expand our design performance group - let Peter or me know if you have someone to recommend to us! Here's the description. 

MSA has issued a safety advisory because they have received field reports that their green colored MSA V-Gard Protective Caps are cracking. Please share this with your safety staff if they do not already know. Let's keep everyone safe!

Apologies if some of you are seeing this for the second time - on behalf of Frances Yang, Mike Gryniuk and the Carbon Leadership Forum, consider signing on in support of the SE 2050 Challenge for structural engineers. (Yes, there is an option to sign on as a non-structural engineer, in support of the program.)

We are hoping to collect a list of leads for him once the dust settles on his move and he begins his job hunt. If you have any... Read more

I'm sure many of you remember when Greenbuild 2020 was scheduled for the week of the presidential election and if was shifted back one day. 

If anyone has small kids and have gone to book your Greenbuild 2022 travel, you've potentially noticed (as I have) that I'll have to travel on 10/31 and will miss all Halloween activities with my... Read more

Does anyone know of a good summary of state and local energy code adoption for new building and ordinances for existing buildings? I know of this energycodes.gov site, but it feels somewhat misleading when you dig into it. For example, in CO, it suggests there is no min code, but there is, and it doesn’t show the extent to which local govs are... Read more

It's been a while since I've given a presenation on this topic. ... Read more

I've been hearing a lot of talk about density becoming a thing of the past. Like with the danger of antimicrobials, it would be great to have some more in depth backup information on whether density is really a danger factor, or if other factors are more important, when we go into these conversations. Does anybody have any new or better... Read more
