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

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 SDLers: ESG Investing is mushrooming which is a very good thing. AIA National, for example, just switched over to 100% ESG investments. With it, there seems to be a growing number of "ESG-lite" options. I'm wondering if anyone among this informed group has recommendations on how to determine a quality investment approach. I'd appreciate any... Read more

Hi all,

We have been noodling on how to preference socially just building products and are feeling a little overwhelmed by the number of questions that we would need to ask our suppliers. Essentially we find ourselves wishing that there was a fair trade label for building products very similar to the one for global agriculture. Or, maybe... Read more

Faucets with high flow rates waste water—not to mention the energy used to treat and deliver it to our buildings—and the additional water stresses our wastewater treatment systems.

Dear All!

Crowdsourcing here to see if anyone has access to two LCA's that can be used to compare functionally equivalent consumer products: a fossil fuel powered to a battery one?  (A good product might be a car or stove, or a heating system with a boiler compared to a heat pump, perhaps?  Needs to include the B-use phase probably...)...
