Hi friends, 

Before i forget, here is the checklist I mentioned yesterday that got such a positive response in our office - again it came about after i was asked (for the Nth time) to write a sustainability description for a concept proposal/ RFP that I was not a part of and frankly didn't have a lot going for it. So it's framed as "you... Read more

Hi All,

I'm teaching a class this semester at CU Boulder on Zero Carbon Buildings and Cities (a new class that I'm making up as I go). The hardest part, I'm finding, is locating some good materials that cover the basics of energy efficiency for non-building engineers or designers (we are energy and sustainability generalists in this...

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.

Has anyone heard of floating solar technology? I can't think of an application other than covering power plant retention or agricultural waste lagoons. Covering up the sun on a natural body of water and adding electrical wiring seems like a bad idea. I am curious though if others have heard of this technology and have other (unbiased) ideas...

Hi all! I'm very excited to report that we have interest from a developer client in tracking embodied carbon through construction. We have issued construction documents and the construction managment team is begining the process to establish the GMP.

We're looking to use EC3, and/ or ZGF's LCA analysis tool for concrete to look at how we... Read more

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...

I’m curious what people think.

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

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

This are opportunities for us to get involved as design and construction allies with the new administration and the US Department of Energy on more efficient building.

The first link below is for low-carbon projects that will provide the case studies and solutions that the industry can follow.  The second is identifying barriers and... Read more

Conventional roofs contribute to heat loss, heat islands, and excessive stormwater runoff.

BuildingGreen-Approved Green Roofs

BuildingGreen approves systems with appropriate planting media that can be created from regional materials and may be blended for specific characteristics, such as:

I'm working on the Best Practice pages, and I want to verify the role of "BITuser experts" (analogous to LEEDuser experts, as shown on this credit page). My questions:

Note that the role of the expert,... Read more
