I’m a volunteer member of the ASHRAE 209 ("Energy Simulation Aided Design for Buildings Except Low-Rise Residential Buildings”) Committee.  Are you familiar with ASHRAE 209? It was first published in 2018, and it outlines a process for incorporating energy modeling into the design process. 

From the forward:

I've been seeing Armstrong's DC flexzone ceiling system at Greenbuild for many years. I'm working on a net zero project with LED lights and solar panels. In theory, the transmission losses in going from DC power from panels to AC for the building to DC for the lights would be eliminated. But does anyone actually have experience using this...

THIS WEBINAR PURCHASE AND REGISTRATION IS CLOSED.

Hot spots: they might sound like fun places to hang out and have a drink—but in green building, they’re actually a bad thing. Something you track down so you can get rid of it. Kind of like being an environmentalist bounty hunter.

Life-cycle assessment (LCA) is... Read more

Hi folks,

We had a rich conversation in our monthly meeting last week. I've summarized the highlights below. Next call is July 11 at 2pm eastern. If it isn't already in your calendar, here's the Zoom link.

What’s on people’s minds?

Looking into high-temp water-source heat pumps for industrial applications. Transom and... Read more

Gypsum is calcium sulfate dehydrate, which is mined or produced as a byproduct of flue gas desulphurization (FGD) from coal-fired power plants. FGD gypsum may contain trace contaminants from coal processing, but not enough to represent a hazard to users. Years ago, some imported products created indoor air quality problems that required...

Hi, and welcome to the Sustainable MEP Leaders Peer Network! 

This online forum is one of the ways we can stay connected and support each other as we collaborate to help MEP design achieve its highest potential as an element of sustainable and regenerative buildings. Please introduce yourself with a little about where you work, what you'... Read more

I'm definitely slow on the draw here, but happy to be congratulating you, Allen! What a great recognition of your work as a firm! And I love that the story about it highlights the firm's diversity.

Also worth noting--just 'cause no one here has said it yet--how cool it is that Ed Mazria won the Gold Medal this, and that AIA updated it's... Read more

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

Hi everyone,

Remember the thread on here from last fall that “broke the internet?” We have some progress to share and a chance for members to re-engage. A core team has been meeting to compare project process diagrams and challenges. They will share examples from their firms, along with learnings and best practices, on Wednesday, March 6...

What is the status of the roof insulation market regarding non-halogen containing polyiso boards? I know GAF and Atlas still have them. I thought JM had them as well, but seems to have taken them off the menu. Are there performance issues?

Can anyone point me to a (dream?) resource listing effective R-values of various wall assemblies?  We are trying to find a cost-effective R-40 wall assembly for a one and two story public middle school targeting net zero energy in Oregon.  Referencing Seonhee's "thermal bridging" thread in late April, I used Therm's native drawing feature, but...

Hello Everyone,

Happy Monday, here is the link to the 2019 SDL Summer Summit Report!

Enjoy,

Our firm held off from signing the AIA Materials Pledge because it was perceived as a feel-good commitment to promise to have good intentions, with no tracking.  I was pleased to learn yesterday that reporting for signatories of the AIA Materials Pledge would "open" today (July 18) and close August 31, and would include mandatory reporting on...

We have a project that is looking for plaster/stucco/textured wall products that are sustainable, or “more sustainable.”

I know these products exist, but I haven’t had to spec or work with any, so I’m reaching out.

The project is in MA, so I'm also soliciting recommendations for products and/or companies who are experienced using... Read more
