Dear Colleagues,

I proposed CarbonCure for a project and the structural engineer in the meeting was opposed to it. He later sent me detailed reasoning by email. I have not used this technology and would like to hear other more experienced opinions on the technology. The project we are working on is well integrated with climate, 99% sDA,... 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

Morning SDL,

Working on a midwest lab and trying to make the case for electrification in a slower greening grid with a reluctant MEP team. Here are a few sources I have checked for case studies:

Building materials emit massive amounts of carbon long before the lights go on.

In this course, BuildingGreen takes an analytical look at the greenhouse gases that are emitted in the process of constructing our buildings in the first place—the embodied carbon. The report focuses on how architects and designers, working with other key... Read more

Good Morning;

I wanted to share a resource that everybody might not be aware of - HomeFree by the Healthy Building Network which can be found here:  https://homefree.healthybuilding.net/products

This is the body field.

The construction sector’s take-make-waste approach to materials needs an overhaul. Materials and construction account for an estimated 11% of global greenhouse gas emissions annually. At the other end of the life cycle, demolition in the United States annually generates 90% of some 600 million tons of construction-sector debris. Getting trashed... Read more

Hi all - Can you help me with a list of states with pending electrification/fossil fuel free ordinances? I am providing some technical aasistance for an article that is going to press soon. The author has listed WA, CO, and MA but I'm unsure how far each of these go and if it's technically correct to call them electrification ordinances.

Has anyone heard of floating solar technology? I can't think of an application other than covering power plant retention or agricultural waste lagoons. Covering up the sun on a natural body of water and adding electrical wiring seems like a bad idea. I am curious though if others have heard of this technology and have other (unbiased) ideas...

All--

Metropolis magazine asked me to write a long piece about the current state of post-occupancy studies. I'm wrestling with whether to do it and how to approach it, but it would be helpful to hear your thoughts on the following--

--importance of the topic

--typical and atypical approaches and criteria

--examples... Read more
