Hey All,

Those of us in the electrification working group have been talking about the impending release of this new NREL tool, which provides hourly (TOU) GHG emissions forecasts for grid regions around the country. This will be a useful tool in evaluating the impacts of HVAC electrifcation, EV integration, load shifting, storage, etc. I... Read more

Split systems are multi-component units that use an outdoor condenser along with separate indoor fan coils to move refrigerant—and provide heating and cooling—in buildings without the need for ducts.

BuildingGreen-Approved Systems

BuildingGreen approves mini-splits that are tested to AHRI standards and have minimum SEER and an... Read more

Hey SDL,

I'm curious if anybody out there has developed specification language requiring a certain level of airtightness (as assessed via one or a series of blower door tests) for a commercial project when it is not going for a Passive House certification and a blower door test is not required by code--basically, something in the...

Hi folks,

I'm looking into lower-carbon pipe options for HVAC and plumbing. The MEP 2040 has slides from a Buro Happold study in 2020 showing PEX to be much lower in embodied carbon than copper, which is unsurprising. CPVC is also a lower-carbon option.

But PVC has its issues and neither PVC nor PEX are recyclable (especially if... Read more

As if you weren't worrying enough already, here's a little something that I ran across through monitoring activity on the American Society of Healthcare Engineers discussion boards:  https://www.id-hub.com/2018/10/17/hospital-plumbing-reservoir-resistance-interview-amy-mathers/, "Hospital Plumbing as a Reservoir for Resistance".  This is both a...

Friends of EPIC –

Hey, everyone. As some of you might have heard, we’ve been working for a while with Autodesk to get c.scale (the data model behind EPIC) built into Forma – Autodesk’s AI-powered planning tool. Forma is packaged within Autodesk’s AEC collection and most firms using Revit should already have access. This integration is... Read more

New Guide to Thermal Insulation Report

The BuildingGreen Guide to Insulation provides detailed guidance on insulation products and practices, including cost comparisons and detailed recommendations on what insulation to use, and what to avoid. It's a treasure... Read more

We have an MEP engineer that is calculating peak loads at about 6 times passive house levels on a large commercial building that is at or near passive house levels of insulation and air infiltration. We suspect one reason is that he is figuring a 50% efficiency level for the ERV. We are showing him ERV systems with 80-90% efficiency, but they... Read more

I have a client that is very interested in automated shades for a mid-rise multi-family housing project. Do you have any examples of projects that have attempted this? I assume it would involve occupancy sensors and/or an over-rideable default setting dependant on sun position and temperature. I also have an MEP Engineer team that is having a... Read more

Hi SD Leaders,

As you may be aware, this past April a group of manufacturers calling themselves the Living Product 50 responded to the letters that many of us sent about five years ago advocating for transparency in their product ingredients.  A copy of that letter can be reviewed about midway through the page at this link:  https://...

Hi everyone,

As part of our monthly SDLS call yesterday, we looked through the 2020 SD Leaders Winter Summit Report. To help paint an even fuller picture of what was covered at that summit, here are slides from many of the 5-minute presentations.

As a note: we have permission from these presenters to share their slides within the... Read more

hi all! I'm almost at the finish line with this year's 2030 reporting...whew. I'm running into an issue that I wanted to throw out to this group, regarding the zero tool and national average baselines. Hoping some of y'all who manage your firm's 2030 data, or are just more familiar with CBECS and related data, have some insight / experience to... Read more

All,

The current version of the program manual includes ID numbers for the best practices, as shown below. I know we want to keep a quick reference number or ID, but though it would be worth asking if we want to use the below, reorder them in some way, or use a different kind of ID. Opinions?

Thanks,
Jenny

Have any of you relied on Green Badger for LEED documentation on projects?

I am familiar with the tool and know Tommy from my time in Atlanta, but have not used it on a construction project.

Have you found value? Thoughts?

Either way, they publish a pretty nifty "LEED v4 Construction Tool Kit" that may be useful for your... Read more
