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?

Hi All,

The SMEPL's Embodied Carbon committee has been hard at work developing a letter that calls for MEP equipment vendors to increase material transparency in their products.  As a way of contacting the most widely-used vendors first, we're asking each of you to enter your "Top 3" specified vendors for each of the products listed in...

Hi everyone,

During the "Integrating Social Sustainability" session at the Winter Summit, an idea was hatched to form a working group dedicated to understanding how equity services can benefit a client's pro forma. Our first step (of course) is to identify the range of services captured under "equity services" and we'd love to speak with... Read more

Hi Everyone,

This book grew out of a decade of thinking about how sustainability fits within architectural practice. It explores the reasons... Read more

We're now mid-way through Summer Summit season! One of the “good problem to have” challenges we’ve had at recent SDL Summits has been too many great five-minute presentations. It’s hard to find time for them all. This year, since we’ll be online anyway, we can get a jump on that by starting the five-minute presentations early in addition to... Read more

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- If you use Procore....

Are your jobs using a template to conduct and create "reports" of their IAQ inspections? Did you set it up in forms or inspections? Would you mind sharing an example template with me? I know Green Badger has a great app to do this, which we use. We would use inspections in Procore for jobs that are not using... Read more

Hi, all. We missed you at the standing check in today. We have a couple of questions for the BG team:

1. What is the timing criteria you need for Best Practice content? We need to back into a deadline on submissions and believe your critical path timing will help define ours.

2. Can you elaborate on what LEED User/BG content may... Read more

Hi folks,

I'm looking into lower-carbon pipe options for HVAC and plumbing. The MEP 2040 has slides from a Buro Happold study in 2020 showing PEX to be much lower in embodied carbon than copper, which is unsurprising. CPVC is also a lower-carbon option.

But PVC has its issues and neither PVC nor PEX are recyclable (especially if... Read more

An elevator system can account for 4%–10% of a building's electric energy load, without considering impacts on heating and cooling. Conventional finishes are also common.

BuildingGreen-Approved Systems

We approve the most efficient tension elevators from leading manufacturers, including models that incorporate:

Food waste is a major source of greenhouse gas emissions from landfills due to methane released during anaerobic decomposition.

BuildingGreen-Approved Composters

BuildingGreen approves in-vessel commercial composters, which require the smallest footprint and are most likely to be suitable for a densely populated area.

Why... Read more
