What better way to follow up the magic of a live presentation from Peter Yost than with 30 free days of BuildingGreen Premium?

Does anyone have language from an RFP that had specific performance criteria included that they could share? Such as a specific EUI target, detailed language about net zero, passive house, etc.

Hey SDL,

I'm curious if anybody out there has developed specification language requiring a certain level of airtightness (as assessed via one or a series of blower door tests) for a commercial project when it is not going for a Passive House certification and a blower door test is not required by code--basically, something in the...

I'll start. I'm Nadav, president at... 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

Churn and renovations can disrupt occupants, release or introduce indoor pollutants, and increase the embodied footprint of a building.

Hi all,

We have a newly constructed, core/shell project having some hot water issues in the core restrooms.

There is a 0.35 Toto lav installed throughout. The hot water heaters are adjacent on each floor, located in the janitor closets. We did the math, and there could be a gallon of water standing and cooling in the pipe between... Read more

Hey All,

Those of us in the electrification working group have been talking about the impending release of this new NREL tool, which provides hourly (TOU) GHG emissions forecasts for grid regions around the country. This will be a useful tool in evaluating the impacts of HVAC electrifcation, EV integration, load shifting, storage, etc. I... Read more

Hi, folks!

I'm sure if I hop in the way back machine I could look in the forums and find old threads on LEED GA and LEED AP study resources, but I also know that material comes in and out of date. Has anyone found a good, current solution for firmwide LEED study materials?

We used to have some GBES resources, but those are intended to be person-... 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
