Hi Leaders,

If your experience was anything like mine, it was a stressful night. I'm feeling a hunger for talking with smart, passionate people about what this all means.

I'm not interested in making this into a political forum--we can all get plenty of that elsewhere. But if you'd like to hang out and just process how you're... Read more

Hi all,

As follow-up to the summit, I’m attaching a draft letter on MEP embodied carbon written by our group (Luke, Kristy, Adam).  The goal is to start a dialogue with manufacturers to include embodied carbon info for major equipment.  Will explain more on the call.  Please read in advance if you get the chance!

Thanks!

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.

I'm looking to compare using an electric tower crane vs a diesel generated tower crane.  I've got the average gallons/hour for the size of crane I'm looking at, but when I reached out to the crane manufacturers, they can only tell me what size electric supply I need to provide, not the kWh usage for the cranes.  I know that it varies depending...
