Championing the

Hi All,

I want to share this report, released today, that I and some other folks on Green Gurus have been working on.  The report dispels the myth that Zero Energy Buildings cost more (specifically in Massachusetts) and it goes further, making the case that Zero Energy Buildings are actually great investments.  Take a look, tell us what...

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

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...

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

Hi- Happy Monday!  

Does anyone know if there is an open-source list of manufacturers that have take-back programs? Looking for a summary/spreadsheet with details (costs, qty, etc). I have a small list but I'm guessing there is already one out there...

Also, Doesn't stage D in LCA account for take-back programs? Could this be... Read more

Has anyone submited this credit in lieu of demand response before?  I'm attempting on multiple projects but not sure what to expect review wise or how much confidence to have in the ability to get more than 1 point for trying.

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

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

Interior doors may be a source of indoor emissions, and wood can be unsustainably sourced.

BuildingGreen-Approved Doors

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!

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 for examples of adaptive reuse projects that have addressed current or future flooding by elevating floors from the existing condition.
