This is something I have been tracking since last year. The same or similar bill was introduced in 2022 but failed by one vote. This would mandate carbon reporting for any company with revenue of $1B or more AND which does business in California. Unlike the upcoming SEC reporting requirements, this would apply to both private and public... Read more

What a great first day!

Here are the slides from the show and tell presentations last night at SOM's office; everyone who presented with slides has given approval to share them.

For those of you who are close to CLT and mass timber, has the jump in US wood price also impacted the pricing of CLT on your projects, or viability of CLT compared to the cost of steel or concrete frame buildings?  

If anyone has price data comparing CLT today to pre-Covid pricing or any metric that would describe the percentage change... Read more

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.

RDI is incorporated as a... Read more

Hi - I'm wondering if you have recommendations for a web/mobile app for occupants to self-assess comfort at regular intervals. I've downloaded comfy, but it wants to actually DO something about thermal discomfort by alerting discomfort and connecting, I believe, to the BMS. We just want to collect information at this point. And since I'm a... Read more

I'm sure we'll learn more soon, but several people have asked on various platforms about how Betsy del Monte is doing (she lives in Asheville, NC, which was hard hit by Hurricane Helene). 

I had a brief text exchange with her on Saturday 28 September, and I feel sure that she would be OK with my sharing it with you all: 

We’re... Read more

Hi Green Gurus,

We have a lot going on this week, and I know it’s hard to keep track of everything, so I’m providing this quick update.

Conveniently, we have also just launched the new Peer Networks Hub on BuildingGreen.com, with a Calendar page where you can see all upcoming events (and a link to recordings of past events). You... Read more

We had so much fun at our Contractor coffee talk that I reached out to our MEP friends to see if they would set up something similar.  And they have agreed to host a talk on Thursday December 2, at 1-2pm EST.  They will talk about decarbonizing buildings, on a schedule that keeps us under the 1.5° C limit and will also address strategies for...

Hi Everyone! 

I am building our internal/firm resources around sustainable design, and creating our post-occupancy evaluations is one of those resources. Does anyone have references or resources they'd recommend me to look into for post-occupancy evaluations? So far I am considering a few evalutation types: building user input, building... Read more

I thought some folks here might be interested in a webinar we have coming up this Thursday 12/6 on the topic of best practices for occupant comfort surveys. Although this webinar is part of our Roast launch series, it will be tool agnostic, with information that will be applicable to any occupant survey regardless of tools used.

Hi Gurus,

LMN is embarking on a 17-part series to explore a more comprehensive carbon metric via summaries of various topics with lots of link.

Team,

What are the M vs. E vs. P(FP) ratios of fee distribution you use in your company for a commercial office building?  How about a residential/hotel?

Best,
