Revit has a new whistle! Or is it a bell…to add to all it’s other bells and whistles. This one has a green tint to it…literally and figuratively…even if a very dull name: Conceptual Energy Analysis (CEA for short). There is nothing less exciting than the word analysis. (Okay, maybe there is something less exciting, but just work with me here).
The word analysis conjures up mental images of numbers, maybe even formula’s, boring charts and graphs, sitting in long meetings reviewing boring charts and graphs wishing you weren’t sitting right next to the boring guy talking about the boring charts and graphs so you could at least check Facebook on your phone like everyone else in the room is doing (you know who you are)…anyway, you get the idea.
Get ready to rethink the word analysis! Analysis can be exciting! In fact it can be awesome!
What would you say if I told you that in 6 steps, without using anything other than Revit, you could get a preliminary, thumbnail sketch of the potential energy use of your project. I know, I couldn’t believe it when I heard it either. But it’s true. Ready? Here we go:
- Create a new project and save it.
- Create an In-Place Mass (or load a Mass family) and add Mass Floors.
- On the Manage tab, click Locations to set your project Location and pick your nearest Weather Station.
- To orient your building to True North, from your SITE PLAN view, find Orientation in your Properties palette, change it to True North. Then click on the Project Base Point and change the value next to Angle to True North.
- On the Analysis tab, click Energy Settings and check the checkbox next to Create Energy Model.
- While in a non-perspective 3D view, click Analyze Mass Model, give the analysis run a name and send it off to Green Building Studio web service. (If this is your first time, you will have to log in to the Autodesk Subscription Sign In.)
Where did it go? It disappeared! Is it magic?
Nope, it’s in the “clouds”. Revit uploads your project to Green Building Studio (GBS) and then releases your Revit to allow you to continue to work. So while you are continuing to perfect your creation, GBS is crunching away on analyzing your model. When it is done you see a little floating Revit Alert pop up to let you know the analysis is complete. At this point you can see it by going to the Analyze tab and clicking Results & Compare. And whadya know, the graphs and charts are not boring.
As you can see, Revit Conceptual Energy Analysis allows designers to get energy use estimates directly from their massing models to use to compare. And what’s even better, it works with Design Options.
This will be the first in a series of posts on the new Revit Conceptual Energy Analysis. I don’t know how many posts, but I will go until I run out of topics on it or someone asks me to stop. Hope you enjoy them.
