This came up a number of times at the SDL Tempe Summit so I thought I would share. If you have not already I highly recommend this recent research paper from the UW-IDL on the tradeoffs of operational and embodied carbon in envelope design in different climates. As a Passive House nerd it made me question the super-insulated envelope at least... Read more

As if you weren't worrying enough already, here's a little something that I ran across through monitoring activity on the American Society of Healthcare Engineers discussion boards:  https://www.id-hub.com/2018/10/17/hospital-plumbing-reservoir-resistance-interview-amy-mathers/, "Hospital Plumbing as a Reservoir for Resistance".  This is both a...

This article just came up in my news feed. I thought you’d all like to read it. I will point out that C&D-specific MRFs have told me that they are really good at single-stream C & D waste, as long as the drywall is pulled out.  Any drywall in a single-stream C & D dumpster ends up in the landfill. Drywall just breaks apart and gets... Read more

Dennis,

I was wondering if you have any previous experience implementing SSO authentication with Salesforce before and if you had any pointers. This morning I created a developer account on Salesforce and enabled it as an identity provider and am in the process of trying to get Drupal to act as the service provider. The Salesforce...

They say that Louisianans are often late to the party but enjoy catching up.  The state, which had been stuck on ASHRAE 90.1-2007 (commercial) and IECC 2009 (residential) and has just adopted legislation jumping to IECC 2021 / IRC 2021, and commits to automatic upgrades with each 3-year code cycle.  This means we join CA, OR, WA, MA, and VT--...

This just in from Berkeley Earth. The definitive report on 2023 global temperatures. Lots of incredible graphs to peruse but the news is pretty incredible. Actual temperatures far surpassed predictions. "At the start of 2023, we foresaw only a 14% chance that 2023 would become a record warm year, and only a ~1% chance that 2023 would reach 1.5...

Rotary Uninterruptible Power Units

Power interruptions and brief changes in voltage can damage electrical equipment, compromise computer data, shut down manufacturing, and endanger hospital patients. In the case of power outages, generators usually take over, but about 98% of all interruptions last less than ten seconds, and there is a... Read more

I've been asked if I know anything about it, to which the answer is no, but I'd like to get smarter about it and I'm hoping... Read more

Hi all,

We have been noodling on how to preference socially just building products and are feeling a little overwhelmed by the number of questions that we would need to ask our suppliers. Essentially we find ourselves wishing that there was a fair trade label for building products very similar to the one for global agriculture. Or, maybe... Read more
