So I was testing assigning a BIT Expert to a Best Practice and I am having trouble getting the profile image to appear.  

When I upload a profile picture, it appears on the standard profile page from "My Account" but when I navigate to the BIT Best Practice 01, the image does not show and it takes me to another profile page that does... Read more

I'm looking to compare using an electric tower crane vs a diesel generated tower crane.  I've got the average gallons/hour for the size of crane I'm looking at, but when I reached out to the crane manufacturers, they can only tell me what size electric supply I need to provide, not the kWh usage for the cranes.  I know that it varies depending...

Hi all,

The Healthy Building Network, now Habitable, was kind enough to develop printable versions of their Informed Product Guidance for us. I think these are a really great resource for design teams looking to select better product options. While the web version is great, we are using the printable version to hang select sheets around...

In looking for ways to reduce jobsite waste and lower our carbon emissions, I'm working on a business plan for centralized procurement, in lieu of individual project purchasing their own tools, PPE, & consumables.  I'm curious as to how many other GC's on here use (or have used) a central purchasing process and if you have any pros/cons...

Hello SDL Leaders,

Over the past month, I have been working with ILFI to navigate the question of residuals in LBC compliant products vs. products reporting for a Declare label.

Through our conversations, it came to light that ILFI considers the LBC Red List threshold to be 10,000 ppm, rather than the 100 ppm written into the... Read more

Hi Everyone,

Who has worked on a SITES certification and can share the approximate hours involved for administering and completing documentation? A relative sense of the effort compared to LEED would also be helpful, similar to the thread about WELL on this same subject. 

Appreciate any insight. Thanks! -Hilary

Anyone have experience with electric boilers? I think in cold climates it's perhaps the first thought when trying to reduce scope 1 emissions in an HVAC application that would have historically used gas-fired boilers... but it seems like they're only an incremental improvement compared to heat pumps / geothermal / VRF type solutions. We haven't... Read more

Hello,

We are having a discussion / a bit of a debate in our office about the merits and sustainability of different roofing materials. Our current standard is to use a PVC membrane, which we all know is highly toxic. TPO is an obvious alternative that is less toxic, but it has some performance concerns and can often lead to leaking (not... Read more
