Hi all!

I'm working on my first energy positive / passive house multifamily building and trying to figure out the trash/recycling chute. I am curious what solutions you have employed to make the trash chute air tight? We have excluded the whole chute from the envelope.

At our SAL call today, folks were talking about how there was just too much to read about DEI. This is the best short summary I have read about the problems of incorporating it into the organizations where we work. It's much easier to talk the talk than to walk the walk because it takes time and accountability.

We have several projects that are small enough that we don't hire consultants to run energy models. I just received permission to do some training so that I can run these models myself. I am looking at doing this training on eQuest:

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

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...
