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.

Does anyone have experience with:

1. installing heat flux sensors on windows and walls

2. deploying IAQ measurement devices that can log... Read more

Hi all!

A couple years ago now there was an incredible thread here about circadian lighting design and WELL. There was a lot of dipping toes in the water with intent to gather lessons learned and report back.

What have been the high points and low points of circadian lighting design so far? What seems cost-effective and worth... Read more

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

Hey all,

Question for those of you who do in-house daylight analysis about modeling translucent glazing.

We use ClimateStudio for our modeling. It has plenty of material options for clear glazing but nothing for translucent glazing, and we are trying to understand the impacts of a translucent interlayer at some skylights. We can... Read more

I was recently asked about potentially specifying concrete with wood nanoparticles and concrete with biochar as a way to further lower the embodied carbon and to increase concrete strength.  These approaches are something I know nothing about, and wondering if anyone in this group has any experience and/or observations that might be relevant to...

Remember 2013? LEED version 4 had just been released to the public. Hardly anyone was using it, though—not only because they didn’t have to, but also because there just wasn’t a pathway to achieve many of the new credits in the rating systems. Especially the product-related credits in the Materials & Resources category, along with the Low-... Read more

I am working on a new community development in St. Paul that is striving to achieve net-zero energy. We are able to get there mathematically by using the extra generation on light industrial rooftops to offset medium-density housing energy use (all buildings are anticipated to have different, private owners). However, this puts us over... Read more
