Does anyone know about temporary flushout equipment that could be used to augment a building's systems to get additional CFM of OA during construction?  For our non-laboratory type projects the flushout period ends up being too long, especially in either humid summers or frigid winters (Pennsylvania).

Hoping that some of you on either... Read more

Hi all,

The Sustainable MEP Leaders are assembling an industry push to expand the availability of embodied carbon data for MEP equipment. Our first steps are to send a letter to industry announcing a call to action and future educational webinars on the topic, the current draft letter is attached. In a similar manner as the...

Hello Green Gurus,

Our next Peer Networks webinar is coming up in just two weeks! We’ll hear from the Indoor Air Quality Working Group, authors of the recently published whitepaper “Considerations for Continuous Air Quality Monitoring: Simple tips for getting it right, according to IAQ consultants”.

More details will be available... Read more

Pint-flush and non-water urinals can save tens of thousands of gallons of potable water per year. A single non-water-using urinal can save more than 10,000 gallons of water per year compared with the U.S. EPA standard of 1.0 gallon per flush (gpf).

When older 3.0 gpf urinals are replaced, the savings can be as great as 50,000 gallons... Read more

Hi folks,

Mahesh announced today that he's leaving his position as CEO of USGBC, GBCI, and ArkScoru, effective Nov. 1. An interim CEO will be announced tomorrow.

I think that Mahesh did some great things for the organization(s)--and he had some really loyal team members. He could also be challenging to work with--as I learned... Read more

Dear all,

A mechanical engineer on a healthcare project we are working on has asked for help in dividing the ventilation calculations between ASHRAE Standards 170 and 62.1; can anyone here help shed some light on it?

"This is the first time I am working on LEED for a hospital and I am not sure how the template wants me to show... Read more

Hi, a local sustainability not for profit whose board I'm on is considering a vinyl siding collaboration with the Vinyl Sustainability Council, started in 2016 by the Vinyl Institute. There would be some funding to create a program to help recycle siding and a chance to win a full new vinyl cladding. I don't think we should collaborate with... Read more

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

So every year about this time I get to spend many lovely moments with our AIA 2030 Reporting data. In order to make the data useful the CBECS baselines/National baselines aren't great in telling us how we did.

For about half our 15 projects that we report in the average year - performing arts, convention, data science schools, etc - a... Read more

It's been a long process but the letter and all it's reccomendations are drafted and ready to present. The group felt it prudent to post the response here first for a short public... Read more

Welcome to the quiz portion of Designing Natural Ventilation.

Learning Objectives
Upon completing this course, participants will be able to:


1. Explain how natural venting and cooling potentials are realized in buildings.

The headlines are everywhere—from heat waves in Europe to wildfires in the Western U.S. to tropical cyclone flooding in Australia. In this age of climate change, just as there’s an urgent need to reduce carbon emissions and other greenhouse gasses, we also need to adapt and invest in resilience.

Increasingly, owners are asking for risk... Read more

Building materials emit massive amounts of carbon long before the lights go on.

In this course, BuildingGreen takes an analytical look at the greenhouse gases that are emitted in the process of constructing our buildings in the first place—the embodied carbon. The report focuses on how architects and designers, working with other key... Read more

Hello all,

We are looking at ways we can use our specs to reduce toxicity in projects and one step towards that goal may be to require RoHS compliant lighting, switches, alarms, meters, etc., as required by the Small Electrical Components exception in the Living Building Challenge. Based on LBC projects I have been involved with, it... Read more

I was shocked to see this new research. Bad news is that acrylic paints are causing 58% of the microplastics pollution in our ocean. Yes, they are plastic. A recent study by Environmental Action, a Swiss-based scientific research firm, shows us that acrylic paint's role in plastic pollution is much greater than most of us realize. The good news...
