The results from the "CogFx" study are compelling, showing that people in environments with low VOCs and low ambient CO2 levels score higher on tests of cognitive function.  Specifically, they show that providing 40cfm of outdoor air per (actual live) occupant results in significantly higher scores than even the "Enhanced Ventilation" scheme...

Good evening,

I am looking for suggestions to replace"wood" siding at the 25-year-old Lyle Center for Regenerative Studies and as always there is no solution that does it all. There seem to be three main options: wood, composition siding, or fiber cement siding. I am looking for something with low embodied carbon, little maintenance,... Read more

Hi folks,

Oregon’s ZERO Coalition is looking for responses to the question below on local policy for electrification, and I thought tapping this group would be helpful.

Are you aware of any local governments outside of Oregon that are promoting or enforcing electrification?

Berkley, CA is one example that as of Jan 1, 2020... Read more

Looking for an example or case study for a building utilizing a radiant heating/cooling in climate zone 4a. General use type is office with some public assembly spaces, total of 85,000 sf.

As usual, everyone, especially mechanical engineer, is terrified by the thought of "condensation." So far, I read a DGWW case study, "Energy... Read more

Friends,

We put a lot of effort into air tightness design, detailing, and construction administration, often including 6-sided mockup and parital or whole-building blower-door testing.  For commercial buildings, these tests measure air leakage in cfm/sf at 1.57 psf (75pa).  

I came across this research paper several years ago, but... Read more

Hey group,

I'm part of the contractor team on a large commercial project pursuing LBC v3.1 Petal Certification, with one of those petals being materials. This requires the team to meet Imperative 10 Red List.

The ownership group has taken the responsibility of red list vetting as a task of their own. The construction team is to... Read more

Kristen Fritsch, in the thread about ipe wood, asked about resources comparing the carbon footprint of transporting building materials vs the transport mode.  There are people who spend their lives on this topic that I won't presume to speak for, but I'll share a few observations:

Even though freight transport is something like 7% of... Read more

Hi all, 

Internally in our organization, we seem to have plenty of horizontal (infrastructure) resiliency expertise, but I'm finding the vertical resources to be lacking. I'm hoping to build a collection of beginner- to intermediate-level resources to help guide practice/design standards for our reference. Any pointers on good info... Read more

Hi folks, I'm reading Zen and the Art of Saving the Planet (Xmas gift) and came across this quote over the weekend which resonated for me, and thought might for this group as well:

"We may feel immense pressure to save the planet in this lifetime, and we may be afraid that we can never do enough. The stark truth is that the planet doesn'... Read more

Good daylighting intentions can end up increasing glare and solar heat gain.

BuidlingGreen-Approved Lightshelves

We look for lightshelves designed to reflect direct sunlight onto the ceiling, turning what could potentially be glare into diffuse, ambient daylight that penetrates deep into the interior of a building.
