Hi All,

I just tried to post a minute ago but it said my connection was lost, so I'm starting over again. You may see two similar posts from me.

Alejandra and I started a document (attached) with ideas on how we can tackle some of the issues we are currently facing with zero waste, as a follow up to our conversation last Friday... Read more

Were we given any warning that LEED Online and USGBC.org would be down for a week?  

I'm advising a nonprofit organization (the Retreat Farm) on whose board I sit that is renovating a large, 8,000 sf, 19th Century barn into a large community meeting space and wedding venue. We are looking for a source of either folding or stacking chairs that are durable, low-maintenance, and environmentally responsible. We may be seeking... Read more

Check out this new executive order. It is broad and includes a lot of items, but of interest to this group, there are some things in here that we pointed towards in our letter back from the beginning of the year, including 24/7 carbon-free electrical energy, a net-zero emissions portfolio by 2045 and net zero emissions from procurement...

What better way to follow up the magic of a live presentation from Peter Yost than with 30 free days of BuildingGreen Premium?

HI MEP Leaders,

Related to our thread about equipment needed for decarbonization, I have a question about what new or improved equipment is already available now that you're excited about.

Has anyone seen a comparison between IECC 2021 and previous versions of the energy code, including ASHRAE 2010? I'm curious how far ahead code buildings are relative to LEED v4.0, and how much the latest IECC raises the bar relative to the previous. I did a quick search for the LBNL and other studies that look at this, but didn't see anything... Read more

Hi all -

I got this yesterday from Renew Oregon, a credible environmental NGO here in the state.

"A secretive special interest group has filed a petition at the Federal Energy Regulatory Commission (FERC) to take “net metering” rules away from states and make it a federal issue.  Net metering is the program that allows homes and... Read more

Now that Ben has set up access restrictions, we have to decide what message to put on "paywall" screens. For example, on the Best Practices pages, the "Official language" tab is fully accessible, but if an anonymous user clicks on any of the other tabs they'll hit a login wall:

Following my retirement from BuildingGreen, I’m also looking to retire from the nonprofit Resilient Design Institute, which I’ve been leading since 2012. My default plan is to sunset the organization in the fall of 2024, but I wanted to offer the idea of someone (or multiple people) taking over the organization.
