Dear SDL,

After almost 12 years at Sasaki, I have finally decided to leave for a path slightly-less-traveled.

Hi all,

We are looking to study Passive House on a couple small multifamily projects. Our understanding is that WUFI Passive only integrates with SketchUp at this time. Our BIM manager has been trying to find an example of a firm that works in Revit and uses WUFI Passive, to point him in the right direction on workflow. I offered to ask... Read more

Hi all,

Looking from insights from anyone who's been through WELL certification before - we've got a lab/office project pursing WELL down in Florida that is struggling to meet the turbidity level requirements of the WELL W01 prerequisite, specifically with the hot water supply, and we're not sure how to best remediate the issue.  Should...

Hello Green Gurus,

A close colleague of ours, Frances Yang of Arup, is distributing a survey developed in partnership with the Healthy Building Network (HBN).

The survey asks for which product categories you need more health information. Answers will help inform which product categories HBN next incorporates into its HomeFree and... Read more

Hi All,

Has anyone successfully adopted a Revit to ClimateStudio workflow with their new export tool? Right now we are using cove.tool because it works reasonably well with iterative Revit modeling, but are itching to try a more accurate and nuanced alternative.

Thanks for any and all experiences!

Section 901.5.1.3 of the 2018 IgCC includes a requirement that "A critical review shall be performed by an external expert independent of those performing the LCA."  I'm curious as to what other's experiences are with having an external expert review an LCA - how does one find such an expert?  Do you have any favorites that you'd recommend? ...

We are looking into different building skin materials from including GFRC and FRP (amongst others) as alternatives to precast. I remember years ago (when I was at LAS) we had retrofitted a Federal Courthouse with FRP for blast resistance. I kind of remember that at the time it had some pretty high offgassing concerns. I haven't been able to... Read more

My dear collegues,

As I'm sure is true for many of us, the events of the past weeks (months/years/decades...) have emphatically reinforced to me the need for a radical shift in how we meaningfully address JEDI in what we do. One (admittedly small) step I've been thinking about are the statements of reconciliation that have become more... Read more

Board insulation has good thermal performance ranging from about R-4 to R-8 and is used as an integral part of a building envelope’s continuous insulation system.

Because board insulation is used on the building exterior, it is not always subject to the same material health and emissions requirements as batt insulation used inside the... Read more
