We recently purchased two indoor air quality meters in the $200-$300 range and find that they never agree, not even close. I would like to find out what other people's experiences have been, and if they have tested affordable models that... Read more

Prefabricated, or modular, buildings can provide environmental advantages over conventionally constructed buildings. They are built in factories where manufacturing and cost can be tightly controlled, so materials are kept out of the elements, there is less waste, and thermal properties and air sealing can be enhanced. There are also fewer... 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

Hi all, has anyone come across a comprehensive (and recent) study looking at how long buildings actually last (beyond Stewart Brand)? I know of plenty that look at the benefits of reuse, but none that look at existing building stock and how much has been reused vs. demolished. 

As we start looking at embodied carbon metrics, I can't help... 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

Hello SDL!

Has anyone set "Ecosystem Benefits/Service" targets for an individual project or for all their projects? I was previously against the idea of even measuring ecosystem benefits but I've had my mind changed in recent months!

Currently we want to set a target for every project to: "Improve ecosystem benefits on every site... Read more

Hi all!

I've heard several people talk about developing tools for assessing/codifying a client's values for a project as part of an integrated design process (ie. a set of questions, survey, etc.). Would anyone be willing to share?

(Z, are you listening? I specifically recall you mentioning a tool like this...)

Thanks!... Read more

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
