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 Brilliant People: 

I'm hoping you can help me with a quick research question. A local colleague is trying to make the case to replace an existing old slate roof with slate vs. "slate look" asphalt shingles on a local public historic building. The bids are 6X higher for slate over the alternative 25-30 year solutions. They understand... Read more

I read a very misleading article on the AIA's website today regarding antimicrobials and the benefit of microbicidals in paint. It was written by a manufacturer, not a healthcare professional, and was not obviously labeled as sponsored content on the website. (I received the link in an email, which did label it as such).

Hi everyone,

As you may know the ICC has changed the way the IECC will be written in the future and most of us think that will reduce the stringency of the future energy codes that are the biggest lever in the fight against climate change within the buildings sector.

So one of the best pathways forward is via ASHRAE, which has a... Read more

Ventilation fans, kitchen range hoods, and laboratory fume hoods can use significant amounts of energy from both the fan motor and from venting heated/cooled air out of the building—air that then has to be replaced and conditioned by energy-intensive HVAC systems.

BuildingGreen-Approved Ventilation Fans

With the current push for improved window performance to meet energy codes and Passive House, room side low-e coatings can significantly improve window U-values. However, back in 2018 Payette did this excellent study that showed that while room side low-e coatings improved window U-value and increased the interior radiant temperature, the... Read more

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

Guiding Questions: 

In the wake of pandemic WFH requirements, we are looking to revamp employee policies and I thought this type of information share would be something we Green Gurus would love to thought-share on. 

We are a very 'low-policy company' (20 when I joined, now 75 employees currently) and our employee handbook is quite small (5 pages). Most... 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 friends,

As you might have seen from my op ed last week on BuildingGreen.com, I’m convinced that just voting is not enough; we all need to do all we can to improve our chances of success in this election. My wife Janice and I have been writing get-out-the-vote letters using Vote Forward as our platform. I thought it might be fun, and... Read more
