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...

Hi all - at the suggestion of Nadav and some of the Sustainable MEP Leaders, I'm reposting a thread I started a couple days ago in the SMEP forum.

In response to increasingly aggressive (and effective) targeting of building owners (particularly schools), a group of researchers have put their support behind a letter warning against the... Read more

The opportunity for water savings from installing efficient toilets, and from toilet replacement, is significant. In addition to improvements to the traditional gravity system, pressure- and vacuum-assisted flushing systems are available that offer superior performance—albeit often with some increase in flushing noise.

Hi folks,

I hope you're all doing well, despite the heat (thermal, political, social...ugh!).

We've had low turnout on the SAL monthly calls lately; it seems that these aren't a high priority for many of you. That's not necessarily a problem, if you're finding value in being in the network for other reasons, that's fine.

We... Read more

Greetings Gurus, following the AIA COTE Design for Economy concept, does anyone have a resource for a list of building efficiency ratio "targets" by space type? I've always struggled with this initiative. 

Welcome to the quiz portion of Reexamining Priorities in Green Building.

Learning Objectives
Upon completing this course, participants will be able to:


1. Define green building priorities from a few different angles (separating process priorities from outcome priorities).
2. Differentiate those priorities... Read more

Hello,

I will be in NYC for Regenerative Metropolis event at the end of Climate Week NYC. Is anyone else going to Climate Week? Did any events seem particularly worth attending? I've not been before but the only thing I've signed up to is the Nature-Inspired Solutions for a Sustainable Future on Wednesday night at COOKFOX.

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

I'm loving the winning projects this year--congratulations to everyone who participated in making them so great! 

(In case you missed the announcement, here's our slideshow on BuildingGreen, and here are the winners with all the details on AIA.org)

Hi Shane and Dennis,

What return address should we use for BIT User forum notification emails?  Ben suggests something like no-reply@bit-user.org but whatever you like is fine.

Once you decide, please let us know who controls the domain name (e.g. bit-user.org or bitbuilding.org).  Ben will send them instructions for editing the... Read more

Has anyone here found an alternative to XPS for the void former?

A structural engineering contact was included in recent conversations about embodied carbon in insulation materials and brought to our attention that this is a common use for XPS that has nothing to do with its insulating properties. It is typically used where concrete is... Read more

Hi everyone,

Since I know we have a lot of talented people in this group, I'd like to reach out to those of you based in Los Angeles and see if anyone is interested in talking at an upcoming Living Building Challenge collaborative event.  The topic of the meeting is "Selecting Healthy Materials 101: From the perspectives of...

Hello, what acceptable levels of air quality are you using to evaluate natural ventilation strategies for your projects?  In our Living Building we only open windows when PM10, PM2.5, etc. are within LBC and WELL limits.  In a seasonally smoggy urban environment, this limits how often we can utilize natural ventilation even if the outside...

We have a client who just hired their first director of sustainability. That person is looking to connect with other people in similar roles within Healthcare / Hospital organizations. Does anyone have organizations they have worked with who have someone in this role (I know it is less common than other markets) or have a healthcare specific... Read more
