Have any of you relied on Green Badger for LEED documentation on projects?

I am familiar with the tool and know Tommy from my time in Atlanta, but have not used it on a construction project.

Have you found value? Thoughts?

Either way, they publish a pretty nifty "LEED v4 Construction Tool Kit" that may be useful for your... Read more

Hi all,

After almost eleven years in this group, today is my last day at Perkins Eastman as I move on to a new step in my career at JLL (wish me luck!). This group has been invaluable to me both professionally and personally, and I have loved connecting with so many of you over the years, over the course of so many events! I hope to make...

I am looking for examples of police stations and fire stations that are operating at an ENERGY STAR or better level.  Google searches have not provided much to go on - I found one net zero energy police station (Cincinnati Police District 3 West Side).  Curiously, Justice Facilities Review write ups do not include details about energy...

Hi All,

Hello all,

Does anyone know of any Rebate Program for either induction cooking equipment or kitchen electrification (new or existing)? Looking for any local or state or even federal programs (outside of California) that incentivize designing/building/retrofitting towards an all electric kitchen for any program type (institutional, single...

HI All,

I have been tasked with putting together a cost comparison of doing a LEED v4 Gold building vs. making that same building Passive House. Obviously they are two different systems, with two different outcomes, and it's not really intended as a total apples to apples cost comparison, but more a value comparison for a developer....

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

Hi folks,

We've got another timely and engaging webinar lined up! Join Panama Bartholomy and Peter Rumsey for the latest on electrification policy and applications. (As always, if you can't make it at this time that's ok, we'll be recording it.)
