Video: Performing an energy analysis

In the last movie we took our mass model, we brought it into the project file, positioned it on the site and created mass floors to give ourselves a rough idea what square footage is of the building. In this movie we are going to take it little bit further and actually perform a preliminary energy analysis on the building. Now I should say that energy analysis could be the topic of an entire course. We are just going to do a quick introduction to the process here. So I should also mention that in order to use this feature you have to have a subscription with Autodesk. And your login will be required. So I have here on screen a file called Energy Model and this is just simply a copy of the file that we ended with in the last movie.

Performing an energy analysis

In the last movie we took our mass model, we brought it into the project file, positioned it on the site and created mass floors to give ourselves a rough idea what square footage is of the building. In this movie we are going to take it little bit further and actually perform a preliminary energy analysis on the building. Now I should say that energy analysis could be the topic of an entire course. We are just going to do a quick introduction to the process here. So I should also mention that in order to use this feature you have to have a subscription with Autodesk. And your login will be required. So I have here on screen a file called Energy Model and this is just simply a copy of the file that we ended with in the last movie.

So the first thing I am going to do is actually sign in to my account. Now I can do that directly from the Revit interface up here at the top of the screen. So you'll see that there's a Sign In button right here. And it says Autodesk Online Services, and I will click that, choose Sign In and put in my username. And then my Password, and then I will click Sign In. Okay, so now I am signed in. And the next thing that I want to do is click over here on the Analyze tab.

And there is only a few buttons here so that makes it pretty simple. And I am going to click the Energy Settings button first, the one in the middle. Now there's a whole bunch of settings here and I'm not going to go through each and every one, but I'm just going to set a few basic parameters that are necessary to at least get some useful results. And the first one is going to be the Building Type. You scroll through this list; you will see there are all sorts of standard building types in here. And right above the default which is Office is Museum. So since we are working on a Museum we are going to choose that.

The Ground Plane is at our main level, but you can see all of our levels are listed. And the Location, it says default initially, well the default location in Revit and let me widen the screen here a little bit when it loads up, because you can see it's very difficult to actually see the map here, so let's make that a little bit larger. You could see that the default location is Boston, Massachusetts. Well we are in Southern California here for our museum. So what I am going to do is type in Ventura, CA and do a search.

And it will take me there. Now if you know the exact address of your project or the latitude and longitude, you can type those in instead, in this case I am going to just get it in the general area that we plan this on. And then over here there are weather stations listed. So you probably want to choose one that's close by. So I am going to choose that one right there. And I'll click OK. And that sets the location, and you are going to get a more accurate energy analysis if you've got the proper location chosen. Is it New Construction, Sliver Space, it's actually looking at your 3D model and it's looking for a Tolerance, if the faces don't line up exactly so it defaults to 1 foot. I am going to start with that.

And I am going to really leave all the other settings the way they are, but I do want to create an Energy Model. So I am going to check that box and I am going to accept all the defaults, click OK. And it'll tell me if it found any problems. So it found an overlap between some of the solids and they are going to merge them together, so it's actually--I am going to merge in some of the forms of my building. And you can already see that it's kind of changed the way that the building looks. So there's like this perimeter zone that's been defined all the way around the exterior, because you will get different energy requirements for the exterior shell than you do for the inner cores.

And then similarly it's kind of divided up the outside surfaces and so on. Let's go on to Analyze Model. Because this is the first time I'm running it I have to accept the terms. Please read them carefully, and then I can give my energy analysis a name and I'll call this SAMOCA_V1, and then we just wait for the analysis to complete. So it's doing all this up in the cloud in the background and you can continue working.

And when it's done, you can click the Results & Compare button and see. Now if I click that right now, it's going to tell me that it's still processing and it's at 35%, well now it's at 42% so it's moving pretty quickly. But we do have to wait for it to finish processing. And so basically we can continue our work in the model and come back and check it later. So let me come back and check my results here. You could see that the results have finished, it's listed over here. We got a little thumbnail preview of the result. And if I scroll down, I get some basic performance factors at the top, different kinds of the information here of renewable energy, lifecycle costs and lots of tables and graphs, which are showing me the annual cost, the fuel usage, monthly heating loads, cooling loads, fuel consumption, energy consumption and so on.

Even wind roses; this was based on those locations that we indicated, the Ventura CA and that weather station that we chose. So lots of data that we can take back to our designers and use as a basis to possibly make changes to the design in order to achieve more efficiency. So that's a really basic overview of the process. As I said, we could do an entire course on energy modeling. There are lots of resources online both at autodesk.com and a lot of the other sites devoted to Revit. So I encourage you start at Autodesk and look for the tutorials and the information resources that are there.

And then may be just do a Google search and see what's up online at some of the various sites, but there are lots of resources devoted to this topic. Once we take that information back to our designers they may decide that they want to start making some changes and then rerun the analysis to see what the results are. So if I scroll down here on the Project browser, you'll notice that under Families, right here is all the families in the project, there is a Mass category, right there. And if I expand that, here's my Mass model. So I can expand that out, right-click right here and choose Edit and that will take me back to my Massing Family, I am going to expand the Views here and go to my Axonometric View instead of a Camera View that they started off in there.

And maybe I want to make some changes here. So perhaps let's just make a fairly simple change, perhaps we wanted to explore what would happen if this tower was much taller. Let's try something like 120 feet, and perhaps likewise with this tower we want to try making that a little bit taller. Now it was constrained to that top level, so I'm going to remove that constraint to allow me to make it higher. Now both of those changes should have some impact on the overall energy model, but I want to do one other quick change here that will also have an impact possibly on the energy model, but actually also on our square footage calculation.

Actually let's do it a run this side where it's a little more obvious. And that is to just sort of take this Reference Line and I am going to kind of pull it out here. Now I realize that we are crashing into the street. So this is more proof of concept than it is an actual change, okay. But I'm going to pull it out there and you could see that's now a lot larger, so we have made this annex of the building considerably bigger. That should have an impact on our square footage and it should also have an impact on our energy model. So I am going to reload this back into my project and it will tell me that it already exists, and I am going to overwrite that existing version.

And you can see that everything got significantly larger here. And now what I am going to do is analyze the model again. And I'll call this SAMOCA_V2. And then we will wait for that to process. All right, so let's check the results and you could see now that I have two sets of results here, here's our original V1, here is our V2. And you could scroll through them individually and look at all the charts and numbers or you can actually hold down the Ctrl key and select both together and click on this Compare.

You kind of see things refresh over here. Well, you've got to make this window little bit wider and then you'll see all of the results listed side-by-side. Now if you have a wide enough monitor you can actually do this without a scrollbar, but it gives you the general idea and we can start to see some differences in the numbers as we scroll through here. Some of the numbers are going to be unchanged particularly things like the wind roses and so forth, because we are still in the same location. So we wouldn't expect to see any change here, but for the actual amount of fuel usage and the amount of energy consumption you should expect to see some differences here.

You know they are not dramatically different, but certainly some numbers for us to take these comparisons back to our designers and our clients and talk about which way we want to go with the design. And we are going to assume for the sake of argument that this new design, particularly since it encroaches on the street, is probably not the best choice. So we are probably going to go back to something that's closer to V1. But that gives you some idea of how those energy numbers can be used to help you make those decisions. Now just real quickly here, let me jump back down to my Mass Floor Schedule and if you recall in the previous movie, that we were at about 280 square feet.

But you could now see that the result of these changes as we've added a pretty significant amount of square footage. So that's another talking point that we can take back to our design team to make decisions. So in the next movie what we are going to do is taking some of that data and refining the design.
