    Revit MEP for Acoustics? Or do I need Ecotect? Or some other?

    So I've the whole Building Design Suite Ultimate installed on my machine, but I've never opened RVT-MEP or RVT-RST, and although I could and save you all the trouble of reading this, but I think it's a topic worth conversation, so....

    I'm presently engaged in talks with one of our acoustic engineers, looking to see how we might better align our collobrative workflows, and it turns out they're using Sketchup abstractions of our Revit models (not .dwgs exported from Revit imported into the Sketchup, but models built anew!) to do their analysis with what looks like quite primitive software.

    Obviously, it'd be nicer if it were all the more holistic, and acoustic analysis could be done like we can with thermal, so I was wondering if RVT-MEP had acoustic analysis in it these days?

    And if not why not?

    And if the reasons for why not turn out to be "because there's Ecotect" then how does that work for MEP designers only using RVT-MEP ? That suggests (to me) that RVT-MEP is only good for documentation? And so, I guess, does anyone use Ecotect? And if so, are you architects, MEP or both?

    Well, I was looking into Ecotect some time ago. Until it got burned by an accoustic engineer who could prove the acoustic analysis couldn't be done in a way that was appropriate for the Dutch building legislation. Not saying it didn't work, it didn't work for the Dutch market and couldn't be "localised".

    But to my knowledge Revit MEP doesn't doe acoustic analysis. Why not? Well, because it's for Mechanical, Electrical and Plumbing... different ballgame all together.

      Pity for the Dutch I guess, I wonder if it's the same here in the UK.

      I see your point about the program acronym standing for what the program is specialised for - but that as an attitude (not yours) to the software/discipline is quite obstructive. Saying "that's not in my remit" is one thing when protecting profit and liability, but at the same time there should still be give/take in exploratory mixed-discipline design - and I'd certainly say acoustics were more in keeping with the skill set of MEP engineers than Architects or Structure.

      But sadly, obstructiveness is what I've come to expect*:banghead:





      *without wanting to name/shame anyone - and by no means saying Architects are saintly

        Acoustic design is a part of Ecotect. It takes some time to setup all of the materials and their sound properties. You can import your rooms from Revit to be used in Ecotect and perform acoustic analysis. Before you perform the analysis though, you will have to apply the materials you defined beforehand.

        So it is quite a bit of work, but is possible.

          Do things sound differently in the Netherlands? Maybe 2+2=5 there as well..... just mind boggling.

            Nope, but we do have standard regulations on how to calculate/analyze things. For instance, we can't use BREEAM, LEED, or any other 3D, fully integrated, analysis software for calculating energy usage. Instead we're stuck on some lame 2D static calculation rules which do not come close to the "real world". Same with acoustics: calculation method is described in a mandatory set of regulations. And Ecotect doesn't comply... Until someone is willing to chip in 20.000,- or so to have it validated by an independent research facility, it's unusable.

              Might have a look at Acoustic Dimensions, wrote about them on my blog in February 2011.
