Hi all,

I'm wondering if you all have had a meetup at NESEA's Building Energy Boston conference before? Is anyone interested in meeting up this year? I'm open to ideas! If you give me your email address I can attempt to organize an informal meet up on one of the conference days.

For those of you not in the NE part of the country,... Read more

Following up on conversation from the Fika today, Kim said the IRS is supposed to be issuing rules for tax-based (even for orgs that don't pay tax) credits by the end of first quarter.  Sounds like we all just need to be on the look out still.

THIS WEBINAR PURCHASE AND REGISTRATION IS CLOSED.

Hot spots: they might sound like fun places to hang out and have a drink—but in green building, they’re actually a bad thing. Something you track down so you can get rid of it. Kind of like being an environmentalist bounty hunter.

Good evening,

I am looking for suggestions to replace"wood" siding at the 25-year-old Lyle Center for Regenerative Studies and as always there is no solution that does it all. There seem to be three main options: wood, composition siding, or fiber cement siding. I am looking for something with low embodied carbon, little maintenance,... Read more

The Building Decarbonization Practice Guide is extremely helpful but, from their comments, it is all coming... Read more

Kristen Fritsch, in the thread about ipe wood, asked about resources comparing the carbon footprint of transporting building materials vs the transport mode.  There are people who spend their lives on this topic that I won't presume to speak for, but I'll share a few observations:

Everyone agreed during last Friday's meeting that we want to call the site BITuser. The question, however, is what domain name should be used.

Whatever domain name is chosen, it will redirect to the actual site URL -- https://bituser.buildinggreen.com (similar to how LEEDuser.com redirects to https://leeduser.buildinggreen.com).

Hi all,

I've been working on a LEED project in California for months and our energy modeler wants to use the LI 10480 Title 24 2019 pipeline to demonstrate compliance under LEEDv4. Only problem is, I've never done it that way before, and our modeler and I are consistently speaking in different languages. Anyone done a project under this... Read more

Hello everyone,

We are far too often asked to include parking in our buildings (because why shouldn't the average family have 2.1 kids, .8 pets, and 3 cars) and it always grates on me that we are putting so many resources (natural and monetary) into something that is almost certainly single use and will need to be demolished in 30 years...
