For those of you who have attended the event above, I think you will agree this has been a high quality event.  But DFC is changing the forum this year. Instead of holding an annual event in September, this year they are holding 4 half day events around the country.  Attendance will be limited to 40 people and it is focused on sustainability...

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

Wondering if we can have a dialog on HVAC load calculation software... we are currently still using Trane Trace 700, but with the future migration to Trace 3D+ coming are looking into other options. Never used HAP but I haven't heard great things, and we dabbled in IES VE for a while, but went back to Trace since at that time there was no... Read more

Team SCL,

This was a tough week. My husband coined a phrase "20% laid off."

Unfortunately, 50% of our business is currently impacted by governmental orders stating that our work is non-essential. This is bitter-sweet. I certainly want people to be safe, but we've had to make some tough decisions and in the geographies that were... Read more

Hi everyone, it was so great to meet some of you at the winter summit and finally connect names with faces!

We have a project that is targeting CalGreen Tier 2 and LEEDv4 Platinum.  Thought I'd reach out to see if anyone on this forum has found comparison guides between the two?  Looking for something similar to this CalGreen 2013 tier... Read more

Hello SDL friends,

It has been an amazing opportunity to collaborate with so many of you through this group or through my work with Tally, the USGBC, ILFI, and in my role as an environmental researcher at KieranTimberlake. This is not so much a goodbye as it is a "hope to see you soon." I am making a shift away from building design into... Read more

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...

I have a request from an Architecture firm to do a Fitwel Core and Shell certification.  I don't do that type of thing - anybody out there interested in this type of work?

Respond here or just email at me annehicksharney@gmail.com.

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

I read a very misleading article on the AIA's website today regarding antimicrobials and the benefit of microbicidals in paint. It was written by a manufacturer, not a healthcare professional, and was not obviously labeled as sponsored content on the website. (I received the link in an email, which did label it as such).

Hi GGs,

We are looking to do a renovation of a very leaky old office space, and we want to get a good snapshot of air quality and effective envelope R values both before and after.

Does anyone have experience with:

1. installing heat flux sensors on windows and walls

2. deploying IAQ measurement devices that can log... Read more

Thought I'd share this interesting research about something I hadn't considered as another pandemic impact - the use of video in Zoom etc calls vs. audio only. Maybe an excuse to keep your camera off some of the time?
