Dear fellow SCL'ers,

Recently one of our members, Ryan Poole, sustainability leader at DPR, has been facing some personal challenges. His wife is 35 weeks pregnant and was diagnosed with a brain tumor. They have moved across country - from Colorado to South Carolina - to be closer to thier parents and their support system, but they can... Read more

Hey there hive mind,

We went looking through LEEDuser to try and find some direction and didn't find much so I thought I'd bring my team's question here to all of you smart people. We're working on a non-combustion central plant tied to a geothermal field and grid electricity. The project has cooling towers and their associated chemical... Read more

Hello, what acceptable levels of air quality are you using to evaluate natural ventilation strategies for your projects?  In our Living Building we only open windows when PM10, PM2.5, etc. are within LBC and WELL limits.  In a seasonally smoggy urban environment, this limits how often we can utilize natural ventilation even if the outside...

Has anyone here found an alternative to XPS for the void former?

A structural engineering contact was included in recent conversations about embodied carbon in insulation materials and brought to our attention that this is a common use for XPS that has nothing to do with its insulating properties. It is typically used where concrete is... 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:

Hello All-

  We have a K-12 school project that is using a R-60 flat roof assembly as an energy & costing benchmark (along with other energy efficiency measures but this is the relevant detail to our question).  The project mechanical engineer is not onboard with a number of our energy conservation measures and has been sharing...

Are FSC glulams available? By many manufacturers? Which ones?

This might be going down a rabbit hole, but in moving to California this year I noticed that "zero net energy" (ZNE) is the standard term, whereas "net zero energy" (NZE) was more common back east. The DOE's 2015 definition (below) uses "zero energy building" (ZEB), which to me implies a building uses no energy at all.
