First, there was Energy Use reductions

Then there was embodied carbon

Soon it will be refrigerant use/leakage calculations

…and much more

As coordinators and leaders of project teams, what does this look like for the practicing architect and our collaborators?

I have no idea. BUT I’m guessing someone is... Read more

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...

We should probably agree on the correct spelling for what we at BuildingGreen are calling "BITuser." I noticed that on the Salesforce portfolio screenshot provided by Dennis, it's spelled "BIT User."

BITuser has the advantage of more closely resembling LEEDuser, but it has the disadvantage of looking a little weird in all-caps, as in... Read more

Plug loads—the energy consumed by plugged-in devices—can use a substantial amount of the total energy in both residential and commercial buildings.

Hello, friends,

During A'23, Je’Nen and I discussed our desire to send Marsha photos we have... 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...

Hello! 

We have several projects that are either pending ILFI Zero Carbon certification or the owner is planning to purchase offsets to cover construction emissions. Thus far, I have not considered this in our corporate footprint reporting. However, we are including A5 emissions whenever feasible and multiplying that performance over the... Read more

Welcome to the quiz portion of Downscaled Climate Data: Where to Get It and How to Use It.

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


1.  Define “downscaled climate data” and understand where to find it and how to apply it in modeling to achieve greater environmental sustainability and... Read more

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'm looking to compile an outdoor weather station for a local project, and we'd like to add local outdoor CO2 information to our data. I usually work with Onset HOBO products, but they don't offer an outdoor CO2 sensor. Their weather stations can take data from any CO2 sensor with an analog output - does anyone have any suggestions?

Hi all,

We are looking to study Passive House on a couple small multifamily projects. Our understanding is that WUFI Passive only integrates with SketchUp at this time. Our BIM manager has been trying to find an example of a firm that works in Revit and uses WUFI Passive, to point him in the right direction on workflow. I offered to ask... Read more

The results from the "CogFx" study are compelling, showing that people in environments with low VOCs and low ambient CO2 levels score higher on tests of cognitive function.  Specifically, they show that providing 40cfm of outdoor air per (actual live) occupant results in significantly higher scores than even the "Enhanced Ventilation" scheme...

Hello all, 

Any Fitwel experts out there? I have a 30,000 sf boutique hotel + spa client who would like to certify under the Fitwel rating system but Fitwel folks are telling me that no scorecard is currently available to hotel clients (can't use mulit-tenant or resi, that a hotel scorecard is under development). Has anyone used Fitwel... Read more
