Lake|Flato developed a project process road map as an internal project management tool over a decade ago, and we're looking into updating it.  It serves as a sort of "checklist" of major design, sustainability, and QA/QC milestones for each project phase.  I know we've talked about similar tools at other firms at past SDL summits, so wanted to...

I just saw this post from Conor on LinkedIn.

Starting in January 2019, all new Columbia Construction Company projects require LED temp lighting.

Are others doing this too? Frankly, given all the benefits and how quickly the industry is matured, it's hard for me to understand why anyone would use anything other than LEDs on a job.... Read more

Greetings Gurus, following the AIA COTE Design for Economy concept, does anyone have a resource for a list of building efficiency ratio "targets" by space type? I've always struggled with this initiative.

This is not so much a goodbye as it is a "hope to see you soon." I am making a shift away from building design into... Read more

Hello, what acceptable levels of air quality are you using to evaluate natural ventilation strategies for your projects?  In our Living Building we only open windows when PM10, PM2.5, etc. are within LBC and WELL limits.  In a seasonally smoggy urban environment, this limits how often we can utilize natural ventilation even if the outside...

Has anyone heard of floating solar technology? I can't think of an application other than covering power plant retention or agricultural waste lagoons. Covering up the sun on a natural body of water and adding electrical wiring seems like a bad idea. I am curious though if others have heard of this technology and have other (unbiased) ideas...
