A brief non-technical rant about OneClick LCA - from someone who is not actually USING the tool, but lobbying for its access.  Wondering if you all have better intel, or if it is just me.

We are working on a number of projects for which te teams are using OneClick LCA - for some cases it has a better international data set than others. ... Read more

Hi SD Leaders: I'm writing to get your help identifying any experts or projects where all-electric HVAC solutions are being implemented in a large new build healthcare/patient care setting. The client has raised concerns about the reliability of an electric re-heat system and its ability to promptly respond to temperature controls. They also... Read more

The ReUse Map created through the Material Flows Working Group is live and got some great traction at Greenbuild (Thank you Nadav and Barbara!).

To keep the map relevant and updated, we'll be looking at how to fund the maintenance of the map, the best ways to get the word out and looking at writing a white paper. If you want to be part... Read more

I'm looking for successful examples of net-zero, Living Building, or similar office buildings that are NOT owned by highly-motivated organizations like RMI or the Bullitt Foundation (or one of your firms).

We are looking to team with a developer on a small-mid-size office building that will house our new office with us as a tenant (no... Read more

Hi folks,

I'm looking into lower-carbon pipe options for HVAC and plumbing. The MEP 2040 has slides from a Buro Happold study in 2020 showing PEX to be much lower in embodied carbon than copper, which is unsurprising. CPVC is also a lower-carbon option.

But PVC has its issues and neither PVC nor PEX are recyclable (especially if... Read more

Hey SDL,

I'm curious if anybody out there has developed specification language requiring a certain level of airtightness (as assessed via one or a series of blower door tests) for a commercial project when it is not going for a Passive House certification and a blower door test is not required by code--basically, something in the...

Sheathing should be designed for durability, but some sheathing materials can be toxic or may contribute to moisture issues inside the building envelope.

Sheathing approved by BuildingGreen contains recycled content, rapidly renewable materials, or otherwise provides exceptional performance, such... Read more

To piggyback off Nathan's introduction where he mentions construction waste management, who is doing anything innovative or different in managing construction waste?  Construction waste has not historically been a passion of mine, but now working in sustainability and construction, I feel like it has to be by default.  

We have a... Read more

I'm just wondering if anyone is using GBCI's Better Materials site as their go-to source for transparency and healthy materials.  Having all the search engines on one platform is great in theory, and I keep hoping that it will be the one-stop site/resource that I can get all our designers to use.  Unless I'm missing something though, it still...

The headlines are everywhere—from heat waves in Europe to wildfires in the Western U.S. to tropical cyclone flooding in Australia. In this age of climate change, just as there’s an urgent need to reduce carbon emissions and other greenhouse gasses, we also need to adapt and invest in resilience.

Increasingly, owners are asking for risk... Read more

I have to admit that I wasn't particularly paying attention to LEED during Greenbuild, but anyone recall the "big announcement by USGBC" that LEED v4.1 is coming?

Article can be found @ Green Building Law Update by Stuart Kaplow and the title is "LEED v4.1 Announced by USGBC at Greenbuild."
