Hi all, 

I just wanted to post a quick message to introduce myself to the group. My name is Jeff Geisinger, and I'm an architect with Utile in Boston. We're a 50-ish person firm with a pretty broad project base, including affordable multifamily housing, institutional buildings, commercial interiors, and urban planning/public realm work...

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 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

Hi All,

Has anyone dug into ASHRAE 2016 as part of the new v4.1 requirements or as codes start to adopt it? I recently presented on this and thought I should check my math to make sure I'm understanding and communicating this correctly.

My understanding is that there is a new reference baseline, that is essentially the ASHRAE 2004... Read more

We are having trouble sourcing a LEED compliant wallcovering adhesive. We specified Roman Pro-880 which is low VOC but doesn't have sufficient back up for TVOCs. Have you had success with other products?

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'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in the forums and find old threads on LEED GA and LEED AP study resources, but I also know that material comes in and out of date.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

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? 

All,

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

On a large sports project, we worked with the structural engineer to spec low carbon / high SCM concrete mixes. Much of the floor area will be sealed and polished concrete, and a concrete sub is pushing back on the SCMs saying they should not be above 20% (with a preference for 0%) for the polish to finish properly, per the manufacturer. Anyone... Read more
