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

I'm writing an article surveying and comparing various embodied carbon tools, including whole-building LCA tools. I'm looking for interviewees who have used at least TWO of the three major LCA tools currently in use in North America (Tally, Athena IE, and One Click LCA). If you've tried all three, all the better! If you or someone in your firm... 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

Hello all,

I need future weather files for a project. We are looking at three years, 2050, 2075, and 2095 using two climate change scenarios, low emissions, and high emissions. I have seen ARUP's Weathershift site that uses RCP 8.5 and RCP 4.5. Are we assuming that 2.6 is not achievable? I would have used this as a low emissions scenario... Read more
