Hi everyone, it was so great to meet some of you at the winter summit and finally connect names with faces!

We have a project that is targeting CalGreen Tier 2 and LEEDv4 Platinum.  Thought I'd reach out to see if anyone on this forum has found comparison guides between the two?  Looking for something similar to this CalGreen 2013 tier... Read more

Hi all - at the suggestion of Nadav and some of the Sustainable MEP Leaders, I'm reposting a thread I started a couple days ago in the SMEP forum.

In response to increasingly aggressive (and effective) targeting of building owners (particularly schools), a group of researchers have put their support behind a letter warning against the... Read more

Wondering if we can have a dialog on HVAC load calculation software... we are currently still using Trane Trace 700, but with the future migration to Trace 3D+ coming are looking into other options.

Hi SD Leaders, my firm wants to make a case for conducting LCAs on all major projects. I'm curious what your experience is - how long does it take to conduct an LCA (for the analyst's effort and other project team members who attend meetings about the LCA and use its results), and the type of LCA software you're using. 

I feel sure you'... Read more

Embodied carbon in products and existing buildings. What does LCA tell us about renovation vs. new construction and material choices?

Guiding Questions: 

Hi all,

We have an institutional client who has tired of LEED and is instead putting forth EarthCraft Light Commerical as a replacement certification (they like the performance verification & lower cost that ECLC provides).  Has anyone used ECLC? It seemed an odd choice but wanted to hear from others on their experiences. The... Read more

Hi GGs,

We are looking to do a renovation of a very leaky old office space, and we want to get a good snapshot of air quality and effective envelope R values both before and after.

Thought I'd share this interesting research about something I hadn't considered as another pandemic impact - the use of video in Zoom etc calls vs. audio only. Maybe an excuse to keep your camera off some of the time?

Hi all,

Here's a good follow up to Maria's steel question on Monday.  We have a Midwest project that unfortunately (from a carbon perspective) is required to use a traditional, thick precast facade.  We’re working with the contractor and potential future (not yet bid out) fabricators to determine an appropriate % of pozzolanic material...
