Does adding solar panels reduce a building's EUI?

Existing operational use of a building is 80 kBtu/sf/year. When we add solar, it will change the source of energy but does not change the usage.

My understanding is that the EUI does not change, but it would be good to hear from others.

It's energy consumption at the point... Read more

Ground- and water-source heat pumps move refrigerant or water through the ground or a body of water for use as a heat source (for indoor heating) or heat sink (for indoor cooling).

Hi All - as Environmental, Social and Governance (ESG) becomes increasingly prevalent, I'm trying to learn more about what types of requests for ESG-related information folks are actually receiving and what types of trainings on ESG would be most helpful.  Drilling down a bit, I'm curious as to how ESG data points are moving down the supply...

Does anyone here have a draft spec for low embodied carbon concrete they could share? I see the GSA has a standards sheet with MGWP limits, but we are hoping to actually specify the mix for upcoming projects.

Following up something I mentioned at the summit - the EPA is hosting public comment webinars related to the IRA and construction. The first one seems particularly relevant, 3/2/23 from 2-3.30pm EST “Reducing Embodied GHG Emissions: Construction Materials Prioritization and Environmental Data Improvement”. Good opportunity to have our voices... Read more

Hello! Long shot here, but I thought I would try.

Hi everyone, it was so great to meet some of you at the winter summit and finally connect names with faces!

We have a project that is targeting CalGreen Tier 2 and LEEDv4 Platinum.  Thought I'd reach out to see if anyone on this forum has found comparison guides between the two?  Looking for something similar to this CalGreen 2013 tier... Read more

Curious on stories when IAQ testing for LEED or WELL didn't come back with "all clear, everything's good" results we all hope for. 

I have a project right now where we are tracking down suspicious sources and look forward to telling the full story when it's done being written. 

Thought maybe this would be a good safe space to talk... Read more

Hi all,

I'm sure many (most? all?) of us have heard the changes to LEEDv4's energy standard are coming. If this is news to you, info on the balloted measures that have passed is available online here: https://www.usgbc.org/articles/leed-v4-energy-update-approved-member-ballot.

It was written by a manufacturer, not a healthcare professional, and was not obviously labeled as sponsored content on the website. (I received the link in an email, which did label it as such).
