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...

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 there colleagues!

Out of curiosity, do you plan on attending Greenbuild in person in San Diego in September? My staff asked me if we were going and my answer is partially contingent on the extent to which attending would mean getting to see some of our favorite people (read: all of you). Looking forward to taking the temperature of... Read more

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

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

Hello Gurus,

I have a client (bldg owner) who has asked me to recommend a list of firms who have the internalized resilient design in their practice.

They are *not* asking for resiliency consultants right now, but for firms that they might hire for "regular" capital projects, but since resiliency is high on their priorities, they... Read more

Are your clients asking you about wellness? You’re not alone. Healthy interiors and wellbeing are the trending buzzwords of sustainable design. Lighting design for circadian rhythm and water filtration methods might be on the... Read more

All,

I've probably spoken to a few of you over the phone, but I wanted to make sure all of you know that we are hosting a 4 part webinar series on our Tally LCA software, kicking off tomorrow 10/10. We just released the new of Tally version and ended up doing far more development work than initially anticipated, in no small part due to... Read more

Friends,

As some of you know, I joined Perkins Eastman last year and it has been amazing. After years of being the Sustainable Design Leader at my last firm, this move has meant I can concentrate on project work because we have such an AMAZING team, led by Heather Jaurequi and Tanya Eagle. Unfortunately, that also means I'm not in the... Read more

Hey Peer Network! Curious, if we can crowd-source a solution here for the pervious pavers at our Omaha office (climate zone 5A). Apparently over the years we've tried to add different kinds of fill here (gravel) but it keeps... disappearing. Any recommendations with either a replacement product or fill item?
