Hi folks,

As you've no doubt heard from us by now (several times), in lieu of Summer Summits this year we're offering a combination of events this fall.

At the recent All Networks Workshop in Seattle, I listened with interest to some conversation about including sustainability goals, KPI's, critical materials lists, and other related topics on a G-sheet in the drawing set.  This is something I had not previously considered, but would like to learn more about. 

If you work for a design... Read more

We're now mid-way through Summer Summit season! One of the “good problem to have” challenges we’ve had at recent SDL Summits has been too many great five-minute presentations. It’s hard to find time for them all. This year, since we’ll be online anyway, we can get a jump on that by starting the five-minute presentations early in addition to... Read more

Can anyone point me to a (dream?) resource listing effective R-values of various wall assemblies?  We are trying to find a cost-effective R-40 wall assembly for a one and two story public middle school targeting net zero energy in Oregon.  Referencing Seonhee's "thermal bridging" thread in late April, I used Therm's native drawing feature, but...

Hi all,

The USGBC Pacific Region is launching a new award this year that recognizes projects that have aspires to promote health of occupants and surrounding communities.  In true USGBC style, this award has not been properly publicized, so they are still looking for submissions.  I believe the deadline will be extended to June 7.  I...
