Hi All, this is primarily directed at our Sustainable MEP folks, but please anyone with insight feel free to weigh in.

I am increasingly seeing designs and specifications asking for Passive House levels of airtightness as verified by blower door testing, but with traditional ventilation system designs. 

To me, Passive House US has... Read more

Hi all,

Has anyone been able to find alternatives to vinyl window film products? I can find solutions for wall coverings, but am not having much luck when it comes to window films. Any leads or insight would be really helpful!

Thank you!

Hello- If you use Procore....

Are your jobs using a template to conduct and create "reports" of their IAQ inspections? Did you set it up in forms or inspections? Would you mind sharing an example template with me? I know Green Badger has a great app to do this, which we use. We would use inspections in Procore for jobs that are not using... Read more

Hey everyone,

To piggyback off Nathan's introduction where he mentions construction waste management, who is doing anything innovative or different in managing construction waste?  Construction waste has not historically been a passion of mine, but now working in sustainability and construction, I feel like it has to be by default.  

We have a... 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

I am at a smallish firm (20 people) in Boston helping to reform our processes to enable even those that are not steeped in sustainability at a daily level to be comfortable looking for opporutunities... Read more
