Hi! Just saw this White House press release stating that federal suppliers will need to report on scope 1 & 2, and relevant scope 3 emissions and climate-related financial risks as well as set science-based emission reduction targets. The cutoff for disclosure requirements is $50m in federal contracts. Curious whether this affects any... Read more

Dear SD Leaders: I'm writing to make sure that you've seen a letter that has been circulating protesting the ‘pro-asbestos’ rule change the EPA is considering.  The letter is soliciting firm signatures/owners (as opposed to individuals).  I encourage you to sign and/or get your firm to sign ASAP. 

Please forward as well to any firm from... Read more

Hello all,

I have a quick question for you. While Energy Star appliances are a no-brainer for projects, I don't see a hard requirement to select Energy Star appliances in the energy prereq/credit. There are references in the water section for water using appliances like ice machines, dishwashers, clothes washers, etc., but no related... Read more

We all know the climates are shifting, and the ASHRAE standard that gets invoked for energy codes is shifting along with them--though not in perfect sync.  Louisiana is leaping from ASHRAE 90.1-2007 energy code to 2021 IECC (boom!).  The 2021 IECC as published uses relatively old climate maps; for Louisiana, at least, the same as the 90.1-2007...

Hello Everyone!

Wondering if anyone has expertise in Algae Photobioreactor facades? Here is a product: https://cellparc.com/

My basic understanding is that they produce heat and biogas (as well as providing shade and some thermal value.)  However, I am not clear on the GHG balance benefit, so to speak.  I cannot determine if the... Read more

Anyone have experience with electric boilers? I think in cold climates it's perhaps the first thought when trying to reduce scope 1 emissions in an HVAC application that would have historically used gas-fired boilers... but it seems like they're only an incremental improvement compared to heat pumps / geothermal / VRF type solutions. We haven't... Read more
