Championing the
Changemakers

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

Hi all - 

I have heard a good deal about SBTI in the last while and am wondering about this group’s firms’ engagement with them. We reported one year through CDP, and it was not very useful. It focused entirely on Scope 1 and 2 emissions, which are over 1000x times less than our semi-controllable Scope 3 (buildings’ embodied carbon and... Read more

He just posted the following on the Building Performance Knowledge Community forum:

Does anyone have a recommendation for software that is easy to use and relatively inexpensive for doing energy performance analysis at the schematic design (or before) phase?  We are looking for a tool that gives good quantitative comparisons for... Read more

Good morning. If you're worried  like I am by today's new IPCC Report and would like some helpful explanation I recommend reading climate scientist Zeke Hausfather's lengthy Twitter feed summarizing key aspects with graphics. It's here https://twitter.com/hausfath/status/1424642708291821569?s=21

I've been hearing recommendations for bipolar ionization, as a way to filter airborne virus particles in HVAC systems while avoiding the energy penalty of increased ventilation. However, I've also heard that ionizing equipment is dangerous because it produces ozone.

Does anyone have any insight into the effectiveness and/or cautions... Read more

Something we seem to be seeing a lot in our market recently are projects split into multiple packages - footing / foundation, C&S, and then later a TI package of CD's... mostly in an effort to speed up permitting and construction schedules. (Oftentimes with a contractor on board for a design / build approach). 

My question to the... Read more

Hello, 

I am struggling with understanding if I should be using Annual Marginal Emission Factors (MEF) or Annual Average Emission Factors (AEF) for evaluating different building design decisions.

Everything I know is from this document. So as I understand it ... an individual building or retrofit is going to change the marginal... Read more

Dear Gurus,

At Greenbuild this year I'll be discussing how statistics can lie (in the context of green building claims).  I'm collecting examples of this to prepare.  If any of you know of examples, please send them to me! 

Here are a few of the fun ways statistics might lie that I would be looking for: biased or too-small sample... Read more
