Hey SDL,

I'm curious if anybody out there has developed specification language requiring a certain level of airtightness (as assessed via one or a series of blower door tests) for a commercial project when it is not going for a Passive House certification and a blower door test is not required by code--basically, something in the...

Hi all: I'm looking for experience, insight, or advice as it relates to ISO 14001. I know it is more popular internationally than in the US, and I am trying to ascertain if the the value-add is greater than the cost and effort. If your company is certified, or even if you have looked into it in any capacity, I would love to pick your brain.... Read more

Hi Green Gurus,

We're off to a great start with First Friday Fikas* this year. We've had good turnout and lots of fun. This new tradition continues this Friday at 11:00 am Eastern Time (8:00 am Pacific). We have more fun planned, with prompts to help us get to know each other.

If you registered previously you can use that same... Read more

We have an MEP engineer that is calculating peak loads at about 6 times passive house levels on a large commercial building that is at or near passive house levels of insulation and air infiltration. We suspect one reason is that he is figuring a 50% efficiency level for the ERV. We are showing him ERV systems with 80-90% efficiency, but they... Read more

Hi, folks! 

I was recently asked if BuildingGreen could connect prospective speakers to an event organizer in Chicago. Beyond the leaders in the BuildingGreen networks relayed, I wanted to share that the exercise led me to the Women and Climate speaker database: https://www.womenandclimate.co/speaker-database 

When filtering by... Read more

I'm sure if I hop in the way back machine I could look in the forums and find old threads on LEED GA and LEED AP study resources, but I also know that material comes in and out of date. Has anyone found a good, current solution for firmwide LEED study materials?

We used to have some GBES resources, but those are intended to be person-... Read more

I have reached out to the AIA staff members that I work with on the Energy Leadership Group (AIA ELG) to see about getting into the cycle of updating these standard documents.  Another member of the ELG, architect Kjell Anderson of LMN in Seattle, is interested in working with us on this effort, as he has started including Standard 209 language...

Hello, All!  I'm hoping for your help to keep a green roof on a project of ours.  We have a large healthcare project in the Midwest that is coming in over budget.  To avoid losing our extensive green roof, I'm looking for alternate sources of funding - grants, private sources, etc.  Has anyone gone down this path before and have shareable...

I have a colleague researching existing, proposed, or anticipated changes to urban planning and building codes that encourage lower carbon footprints.

Can anyone comment on or point me to resources on how cities are using carbon footprint analysis and carbon reduction in permitting, now or in the future?

Some specific topics that... Read more

All,

The current version of the program manual includes ID numbers for the best practices, as shown below. I know we want to keep a quick reference number or ID, but though it would be worth asking if we want to use the below, reorder them in some way, or use a different kind of ID. Opinions?

Thanks,
Jenny

Hello everyone,

For those I have yet to meet, I'm Candace Pearson. I've recently rejoined BuildingGreen after a brief interlude at law school and am now getting back into the swing of things with editorial, consulting, and peer networks. 

We had a great turn out at this year's Show and Tell before Greenbuild and all of the... 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

On a large sports project, we worked with the structural engineer to spec low carbon / high SCM concrete mixes. Much of the floor area will be sealed and polished concrete, and a concrete sub is pushing back on the SCMs saying they should not be above 20% (with a preference for 0%) for the polish to finish properly, per the manufacturer. Anyone... Read more

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?
