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.

Hi, a local sustainability not for profit whose board I'm on is considering a vinyl siding collaboration with the Vinyl Sustainability Council, started in 2016 by the Vinyl Institute. There would be some funding to create a program to help recycle siding and a chance to win a full new vinyl cladding. I don't think we should collaborate with... Read more

Folks, would love to hear what software you're for in-house daylighting/energy performance modeling at the SD/DD level. My IT folks have been pushing us to try out Autodesk's Insight again after a not so impressive pilot we did a few years ago. Has it gotten better? Was it us? What programs do you feel good about? Which ones really make you mad... Read more

We are working on a large healthcare project in Minnesota.  We're setting sustainability goals a bit late - no certification, but targets with accountability.  I'm working to determine recycled steel content (for structural steel and rebar), and I've gotten a bit of push-back on recycled content based on being in the region of the Iron Range...

Hi all,

I wanted to reach out to fellow MEP energy modeling teams to assess everyone's experience with the new PCI calculation methodology in 2016. It was a substantial change in how we show savings on projects. Big changes can often come with un-intended consequences. I'm all for pushing to higher efficiency - just want to make sure we...

"With businesses owning over half of all new registered vehicles on the road, it is crucial that companies lead the shift to electric vehicles." Does your role in... Read more

Hi all,

I've tried a couple of different search terms for the forum but haven't been able to find any past conversations on electrochromic glazing yet (which makes me suspect I might be missing something...). We have a potential opportunity to use it in a vertical curtain wall application with a client that is very interested in the... 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

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...

Churn and renovations can disrupt occupants, release or introduce indoor pollutants, and increase the embodied footprint of a building.

Movable partition systems allow spaces to be easily reconfigured, reducing costs and environmental impact. BuildingGreen approves partitions and panels that have... Read more

As I mentioned in my five-minute presentation this morning and then discussed a little more in the break-out on RELi that followed, the full RELi Rating System, in its current form, has now been posted online: http://anyflip.com/zyqc/mdir/

Unfortunately, this is only posted as a flipbook, currently (viewable online only), and isn't... Read more

I am looking at having staff members take a materials course and deciding between Parsons Healthier Materials and AIA Materials Matter certificate programs. Does anyone have feedback on either? Bonus points if you know about both and can provide a direct comparison. Thanks!
