In the past I have used eGRID sub-regions but also State and local utility conversion factors depending on what energy or operational carbon story I... Read more

In trying to help a client write a case study on avoided carbon by using slag and flyash, I am having trouble finding a one for one equivalency that can be verified.

I have found for one pound of flyash, one pound of carbon is saved - but I can't verify that.

Appreciate the feedback!

Hello,

We are in the very early planning phase of a k-8 public school project to be designed and built in an economically challenged urban location with very limited site options.

Hi all,

We are trying to encourage participation in take-back programs and using recyclable packaging with our vendors and I was wondering how we can add it to specifications.

Hi - I'm wondering if you have recommendations for a web/mobile app for occupants to self-assess comfort at regular intervals. I've downloaded comfy, but it wants to actually DO something about thermal discomfort by alerting discomfort and connecting, I believe, to the BMS. We just want to collect information at this point. And since I'm a... Read more

We've gotten some requests recently, so it must be time to update our salary survey. For those didn't participate in the past, we last did one in 2015, and collected some really interesting data about compensation for SDLeaders.

Our first step in getting this started is to recruit a few volunteers who are interested enough in the data we... Read more

Hello SD Leaders!

I recently joined and looking forward to all the amazing dialog. I was told that for membership to be official, I must reveal my unsustainable secret. As much as I preach environmental protection in architecture, I’m a bit of a motorhead with a 1967 HP 289 Mustang that I resurrected from a junk yard when I was 16 — that... Read more
