Hey all,

Thanks to everyone who joined today's peer network webinar - it was great to share what our working group has been developing in the last year. This group gathered to work through a series of decision-making trees to publish some kind of relatively repeatable guidance for how to advance this conversation with a variety of owners...

Hi Everyone, 

This is quite last minute (due tonight) but please see below for an opportunity to email comments to EPA supporting national building material reuse measurement/methodology. Submission is easy, just a short email supporting C&D/reuse and any other thoughts on what to include/exclude in material pathways for reuse beyond... Read more

Ventilation is essential for indoor air quality, but it can bring very hot or very cold outdoor air into conditioned space.

BuildingGreen-Approved ERVs

Heat-recovery ventilators (HRVs) and energy-recovery ventilators (ERVs) can save energy by capturing nearly all of the heat in the air being exchanged. BuildingGreen approves:... Read more

There may be more to come; if you presented but did not yet provide permission for your slides to be... Read more

Here is a fundamental question regarding measuring operational carbon emissions that I'm sure many of you can clarify for me:  Let's say you are considering design options and you want to know the relative contribution of GWP of adding an additional inch of continuous insulation to the building envelope.  The GWP from embodied carbon will...

On LEEDuser we divide checklists into multiple project phases. Specifically:

How many of these phases are relevant for BIT best practices?

Note that we also... Read more

I took a first pass at content for the Energy Audit best practice, see the uploaded file. 

I'm looking to draft some one-page briefs for my consulting engineers to outline what we would like to see in their specs regarding certain materials and systems. For example, letting the plumbing and civil engineers know that we prefer to eliminate PVC pipe and want them to specify alternatives like Polypropylene, cast iron, ABS, etc. The idea... Read more

Hello All,

A group of us (three architects and a builder- sounds like there should be a joke here) were debating this and we  are stumped.

Application: Residential exterior trim.

50 year warrantied composite product of agricultural byproduct with PVC (EPD not published yet) vs 100 year (if primed on all sides and painted or... 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. 

I wanted to alert you to this opportunity to help develop a new ASHRAE Standard. They are especially looking for people who have not served with ASHRAE previously (aka the usual suspects)

ASHRAE Standard 242P, Standard Method for Calculation of Building Operational Greenhouse Gas Emissions

1 Purpose: This standard provides a... Read more

I just saw this post from Conor on LinkedIn.

Starting in January 2019, all new Columbia Construction Company projects require LED temp lighting.

Are others doing this too? Frankly, given all the benefits and how quickly the industry is matured, it's hard for me to understand why anyone would use anything other than LEDs on a job.... Read more

Hi all,

We are about to start a affordable housing passive house project in Boston and in a few presentations I've seen great signs that builders use to try to get the point across to subs as to how important air sealing is. Some are even quite funny! The builder we are working with does not have a sign like this, but is open to ideas.... Read more

I am putting together a presentation for our local AIA conference specifically about shading devices / dynamic glazing / dynamic shading and wonder whether any of you have experience / feedback from projects that used a dynamic system - exterior operable shading or dynamic glazing (like View, Sage).  Any post-construction / post occupancy...

I opened IE11 (Internet Explorer 11) today, and saw a message indicating IE11 will be retired June 15th, 2022. While I have no personal attachment to IE11, it was the only internet browser I could consistantly get to open LEED Online credit templates on the actual website. 

Has anyone found another way to be able to fill out LEED credit... Read more
