Carpet is comfortable, offers good sound control, and offers great aesthetic options. But it is typically made from petrochemicals, and carpet and its adhesives can offgas VOCs. It is also a challenge to recycle, increasing the chances that it will be incinerated or disposed of in a landfill. Broadloom carpet cannot be readily repaired if... Read more

Hi folks,

I'm looking into lower-carbon pipe options for HVAC and plumbing. The MEP 2040 has slides from a Buro Happold study in 2020 showing PEX to be much lower in embodied carbon than copper, which is unsurprising. CPVC is also a lower-carbon option.

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
