I'm curious who in this group has used ASHRAE Standard 209-2018, Energy Simulation Aided Design for Buildings except Low Rise Residential Buildings?

We've used it internally (minimally) as a reference to help better communicate the goals and activities involved with energy modeling at various phases of design. But it seems like there's... Read more

Hey, all. Confirming the forum index on the front side of the pay wall will be searchable. Thanks.

Hello Everyone!

Wondering if anyone has expertise in Algae Photobioreactor facades? Here is a product: https://cellparc.com/

My basic understanding is that they produce heat and biogas (as well as providing shade and some thermal value.)  However, I am not clear on the GHG balance benefit, so to speak.  I cannot determine if the... Read more

Hi amazing people!

Most of our projects are now going with some form of gender neutral/all-gender/inclusive toilet rooms or those that can easily be converted to such. With no urinals, we lose 3 LEED points because urinals are very water-efficient. With urinals, it's not as pure a solution. Do you all just take a hit on the LEED points,... Read more

Hello SCL, 

For those who missed our last call, I am posting the results from the 2023 Contractor's Commitment reporting cycle. Reporting at some of the higher tiers requires sharing case studies or information with SCL or the public. All the information that can be shared publicly (or that I received express permission to share) is now... Read more

Hi, curious if anyone in the group has considered using Fitwel in an existing (built) school project (K-12). 

Would be interested in hearing your experiences and if this tool is a good fit for this type of project.

So our last webinar effort flamed out with the overloaded internet, but we've regrouped and have the session scheduled for this Thursday 4/2 at 1:10.  We pre-recorded the webinar to make sure everything goes smoothly and I have to say that Mike is delivering some pretty fantastic content. It doesn't engage LCA tools, rather focusing on core... Read more

Hello, I'm wondering if anyone out in the network has experience with the following:

>Low carbon concete mixes for polished concrete slabs: we're hearing concerns from our concrete supplier that using a low carbon mix design for a polished concrete slab will cause pitting. What experience do others have?

>Low carbon concrete... Read more

Lake|Flato developed a project process road map as an internal project management tool over a decade ago, and we're looking into updating it.  It serves as a sort of "checklist" of major design, sustainability, and QA/QC milestones for each project phase.  I know we've talked about similar tools at other firms at past SDL summits, so wanted to...

Hi SDL!

Our CM recently offered up the possibility of substituting Pozzotive into our structural and paving concrete mix (www.pozzotive.com) on a large public building. Apparently it is on a level with the cost of standard cement.
We are eager to reduce the project's embodied carbon, and this seems almost too good to be true.
