Anyone using the USG EcoSmart drywall? I'm writing a short product review and am looking for some quick feedback. I'm particularly curious about reduced greenhouse gas emissions and overall cost. Thanks! Brent

I read a very misleading article on the AIA's website today regarding antimicrobials and the benefit of microbicidals in paint. It was written by a manufacturer, not a healthcare professional, and was not obviously labeled as sponsored content on the website. (I received the link in an email, which did label it as such).

Hi all - at the suggestion of Nadav and some of the Sustainable MEP Leaders, I'm reposting a thread I started a couple days ago in the SMEP forum.

In response to increasingly aggressive (and effective) targeting of building owners (particularly schools), a group of researchers have put their support behind a letter warning against the... Read more

Curious what people's 'best' experiences or recommendations are for load calculations and energy modeling regarding electrochromic glazing... hoping I can lean on others as it's just now becoming more of a talking point in our market here in Omaha. 

Specific questions including whether load and energy modeling software are separate (... Read more

Has anyone heard of floating solar technology? I can't think of an application other than covering power plant retention or agricultural waste lagoons. Covering up the sun on a natural body of water and adding electrical wiring seems like a bad idea. I am curious though if others have heard of this technology and have other (unbiased) ideas...

Our guys have started talking about how the built enviroment can address infection transmission in public spaces - places like lobbies and waiting rooms, particularly in applications where people queue - theaters, airport gates, amusment parks, etc.  In the specific case of Covid-19, we know the microbe can be transmitted three ways:  fomite (...

Hi folks,

I hope you're all doing well, despite the heat (thermal, political, social...ugh!).

We've had low turnout on the SAL monthly calls lately; it seems that these aren't a high priority for many of you. That's not necessarily a problem, if you're finding value in being in the network for other reasons, that's fine.

As a proud Minnesotan, I have a hard time imagining how anyone could ignore an... Read more

Hello, All!

Looking for some quick insight from the braintrust into how to best approach project goal-setting.

We’ve been taking a critical look at goal-setting practices to better understand what drives the gap between projects that meet ambitious high-performance targets and those that don’t. Recognizing that goal setting is a... Read more

Ventilation fans, kitchen range hoods, and laboratory fume hoods can use significant amounts of energy from both the fan motor and from venting heated/cooled air out of the building—air that then has to be replaced and conditioned by energy-intensive HVAC systems.
