Team,

See this paper regarding outside air vs. filtration.

MERV-13 is a good way to get most benefits without a huge cost.

Best,

He just posted the following on the Building Performance Knowledge Community forum:

Does anyone have a recommendation for software that is easy to use and relatively inexpensive for doing energy performance analysis at the schematic design (or before) phase?  We are looking for a tool that gives good quantitative comparisons for... Read more

We are working on a large healthcare project in Minnesota.  We're setting sustainability goals a bit late - no certification, but targets with accountability.  I'm working to determine recycled steel content (for structural steel and rebar), and I've gotten a bit of push-back on recycled content based on being in the region of the Iron Range...

Folks, would love to hear what software you're for in-house daylighting/energy performance modeling at the SD/DD level. My IT folks have been pushing us to try out Autodesk's Insight again after a not so impressive pilot we did a few years ago. Has it gotten better? Was it us? What programs do you feel good about? Which ones really make you mad... Read more

I would be interested to hear which parties in our group have participated in the CDP Program and how you are reporting your efforts.  I have talked to several contractors that just submit the data for their offices. I always feel like it is asking about our operations including the jobsites, and wonder how you get there.  I am very much... Read more

All,

Our firm has been struggling to find carbon reduction strategies for concrete that move us beyond a fly ash only approach. Frankly, the knowledge just isn't there internally or with our consultants. We've known that there are a few folks out there that have a deep bag of tricks, but we haven't had the chance to work with them... Read more

Dear All,

Greetings. On this Earth Day, I hope you're enjoying our planet's gifts and also giving your gift with reckless abandon.

As I take a short break to plan what I want to do next, this coming Friday, April 26, will be my last day at HKS. Maybe I will get a Hitchhiker's Guide to the Galaxy tattoo like Paula. 

I... Read more

Hi all,

I've tried a couple of different search terms for the forum but haven't been able to find any past conversations on electrochromic glazing yet (which makes me suspect I might be missing something...). We have a potential opportunity to use it in a vertical curtain wall application with a client that is very interested in the... Read more

Hi all,

I wanted to reach out to fellow MEP energy modeling teams to assess everyone's experience with the new PCI calculation methodology in 2016. It was a substantial change in how we show savings on projects. Big changes can often come with un-intended consequences. I'm all for pushing to higher efficiency - just want to make sure we...

Our building scientist has been using Insight 360 to model daylight and document it for LEED certifications.  However, it appears that Autodesk is no longer fully supporting the tool and may eventually stop all together.  (we have not been able to run simulations for weeks due to a change to how "cloud credits" work on their end that they...

Hi folks,

It's here! Highlights, key takeaways, and pics from our packed few days together in Ashland, Mass. in the 2023 Summer Summit report.

From the intro:

Effectively meeting the challenge of the moment is what the world needs from us. Being grounded and energized by connections and sharing with our peers in a safe... Read more

All - 

We have corporate clients that are starting to request antimicrobials in response to Covid-19. I assume we are not the only ones seeing an increase in these requests. Knowing that the evidence supporting antimicrobials has limited to no efficacy, how are you approaching these conversations? We want to continue to advise based on... Read more

As I mentioned in my five-minute presentation this morning and then discussed a little more in the break-out on RELi that followed, the full RELi Rating System, in its current form, has now been posted online: http://anyflip.com/zyqc/mdir/

Unfortunately, this is only posted as a flipbook, currently (viewable online only), and isn't... Read more

Hello - Other than hiring an acoustic consultant, I am wondering what in-house tools you are using internally at the design stage for modelling acoustic performance? 

Thanks, Mona

Wondering if anyone has a slide presentation on the Framework for Design Excellence that they would be willing to share (to present to students). Rather than defining my request as lazy I'd like to offer up the qualification of efficiency.  

I am looking for examples of adaptive reuse projects that have addressed current or future flooding by elevating floors from the existing condition.

Welcome to the quiz portion of Designing Natural Ventilation.

Learning Objectives
Upon completing this course, participants will be able to:


1. Explain how natural venting and cooling potentials are realized in buildings.
2. Show how natural ventilation and passive cooling strategies can amount to increased... Read more
