Hi folks,

We have a really great webinar set up for Thursday, Oct 25 at 2pm eastern. This one is based on the 5-minute presentation from Heather DeGrella at the Summer Summit--our jaws were on the floor when she presented it there, and we were hungry for more.

Plastic windows come in both ABS and vinyl (PVC). Even though PVC is particularly loathed by environmentalists, energy performance is BuildingGreen's primary green consideration for windows, and some vinyl windows offer exceptionally strong energy performance, often with competitive pricing.

We are attempting to use Tally on a couple projects and are wondering how others are using the tool in their design process. If any experienced users out there would be willing to have a brief phone conversation I would appreciate it. Thanks

Hello SCL peeps, 

Thank you to all the people who filled out our 2021 event survey. Your feedback did help us narrow down the options, but it was still inconclusive about whether there’s enough interest in doing an SCL-only Summit. 

To stay on schedule with our planning (and to make sure the event will pencil out financially), we... Read more

Dear All,

Greetings. On this Earth Day, I hope you're enjoying our planet's gifts and also giving your gift with reckless abandon.

As I take a short break to plan what I want to do next, this coming Friday, April 26, will be my last day at HKS. Maybe I will get a Hitchhiker's Guide to the Galaxy tattoo like Paula. 

I... Read more

He just posted the following on the Building Performance Knowledge Community forum:

Does anyone have a recommendation for software that is easy to use and relatively inexpensive for doing energy performance analysis at the schematic design (or before) phase?  We are looking for a tool that gives good quantitative comparisons for... Read more

All,

Our firm has been struggling to find carbon reduction strategies for concrete that move us beyond a fly ash only approach. Frankly, the knowledge just isn't there internally or with our consultants. We've known that there are a few folks out there that have a deep bag of tricks, but we haven't had the chance to work with them... Read more

I've been hearing recommendations for bipolar ionization, as a way to filter airborne virus particles in HVAC systems while avoiding the energy penalty of increased ventilation. However, I've also heard that ionizing equipment is dangerous because it produces ozone.

Does anyone have any insight into the effectiveness and/or cautions... Read more

Our building scientist has been using Insight 360 to model daylight and document it for LEED certifications.  However, it appears that Autodesk is no longer fully supporting the tool and may eventually stop all together.  (we have not been able to run simulations for weeks due to a change to how "cloud credits" work on their end that they...

Hi All:  We are in the design phase for a 5,700 SF project in NH. The team is taking care to drive down embodied carbon where possible. It will be NZE.

A1-A3 emissions are coming in at 67.15 kgCO2e/sf, of which 11.97 kgCO2e/sf is a hot spot attributed to permeable paving and concrete pavers (a little skewed, since lot and patio sizes... Read more

Dear Gurus,

At Greenbuild this year I'll be discussing how statistics can lie (in the context of green building claims).  I'm collecting examples of this to prepare.  If any of you know of examples, please send them to me! 

Here are a few of the fun ways statistics might lie that I would be looking for: biased or too-small sample... Read more
