Revit Process and Workflow: An Essential Guide to Sustainable Design

MAULINA SAROYA: Welcome to the presentation for Revit Process and Workflow, An Essential Guide to Sustainable Design. My name is Maulina Saroya. I work at DIALOG as a design technology specialist, and my social media information is Maulina_Saroya. Just addressing the safe harbor statement. Please note the AU content is proprietary. Do not copy, post, or distribute without express permission.

About myself, I've been in the industry for over 15 years. My main passion is to stop global warming. And I have been fortunate enough to work with a company, DIALOG, and they have the same values. And the people and projects also align with the values that I have as well. Our future state at DIALOG is we are determined to make the world a better place.

As innovative designers, we continuously nurture our shared knowledge, capacity, and reach. We empower all people to make a difference About our company, we're five studios across North America in San Francisco, Vancouver, Edmonton, and Calgary, and Toronto. We're a fully integrated team of over 600 staff entailing of architecture, interior design, landscape, architecture planning, and urban design, structural, mechanical, and electrical.

I'd like to start off with the thought of the day. It's by Robert Swan. He's an advocate for production of Antarctica and renewable resources. And he has mentioned, and there's a quote that I've pulled, it's, "The greatest threat to our planet is the belief that someone else will save it." So I know we're all here today to be a part in sustainability. That's why we're here for this session. So I call for everybody to make a little bit of a difference today through their workflow and at home as well.

So our agenda for today is that we're going to be holistically, overall, when we're taking a look at this agenda, we're creating a workflow for sustainable design within Revit itself, and we're also going to create the Revit families as well and how they fit into that sustainable design workflow. So Revit families are fluid. They can be changed or updated at any time. Whereas their sustainability, actual workflow, at the beginning, you have to start creating that. And if you don't create that at the beginning of the project, then it will have a trickle-down effect and you won't get the effective output.

So what drove DIALOG to explore this workflow? It's not only that we're passionate personally for sustainability, but we've also signed up for the 2030 Commitment, and that's for the 2030 AIA Commitment, and for the 2050 Structural Engineering Commitment as well. So what is the 2030, and what is the 2050 Commitment? The 2030 Commitment is the AIA commitment for actionable climate strategy that sets the standards and goals for reaching net-zero emissions in the built environment. And the 2050 Commitment is a mission of 2050, which works towards net-zero embodied carbon for structural systems in 2050.

So the 2030 Commitment, which is managed by AIA-- and AIA is the American Institute of Architects-- in this commitment, what's defined is taking responsibility of leadership and offsetting greenhouse gas emissions caused by buildings we create, help measure and report progress towards answering the 2030 challenge, aim to offset the effects of climate change by achieving carbon neutrality in the built environment of the year 2030.

We will continue to evolve our expertise in energy modeling and sustainable design so that we can deliver lasting value to our clients. The 2030 commitment, which is managed by the Structural Engineering Institute and the ASCE, which is the American Society of Civil Engineers, the commitment defined by that is to educate the structural engineering profession on the best practices of sustainable structural design and construction that will lead to net-zero embodied carbon by 2050.

It also will engage in the embodied carbon tracking program within the structural engineering profession, thereby enabling the establishment of appropriate embodied carbon reduction targets until net zero is realized, and will report on the current embodied carbon impacts in trends of various structural systems for different regions throughout the country, and also be an advocate and communicate with clients, the design community, and the public to build an understanding about embodied carbon and impacts of the built environment.

The actual sustainable design process, which we'll talk about in today's session, to get to the Revit workflow, we're going to be doing some pre-workflow in AutoCAD. And as well as before we jump into AutoCAD, we'll be creating the actual workflow for sustainable design. And going through the points here, we're going to be going through the first point, which is the data we input is the data we actually output.

So for example, if we put in a material and we want to calculate the material area, we can't calculate that if we don't put in the accurate material area. So we want to understand how Revit workflow is connected to a sustainable design, and in that, we'll notice that if we put in an effective data input, the output that we get, we can create different studies and analyses with it.

So what we do before the workflow in Revit is what we do with the cadastral file. How does it help us divine positioning in Revit itself? And then we want to take that cadastral file, and we want to set it up and bring it into Revit itself. And for our Revit workflow, we want to link in the DWG into Revit, and we want it to define the positioning. And for Revit family setup, for wall family, we're going to go through an incomplete, partial, and a fully complete wall to show you the example of the data we input is exactly what we output.

So just jumping into it here. So our objectives and goals of this presentation are aligned with the 2030 and 2050 Commitments. You'll notice that the goals of this presentation is to reduce resource consumption, lower energy consumption, reduce waste, lower operating costs, improve health and well-being, and climate change mitigation. So some workflow guidelines before we actually jump into AutoCAD and Revit is we want to create a holistic workflow before we actually get into the crux of things.

So we want to determine the information before execution. What are we inputting into the model, and what exactly are we outputting? So you might want to work backwards with the information and want to determine what exactly is your final product. Are you calculating LCD? Are you calculating carbon emissions? What exactly are you doing? So that's to keep in mind if we don't input any information into our workflow or even the geodetic location or elevation of materials, you're actually not going to output anything in your model.

Once you do create a proper workflow and put in the geodetic elevation, and as well as the Norther and Easting and materials, you'll get an accurate BIM model. And from that BIM model, we can take information such as we can select the correct EPD to calculate the LCA, and we can find out what the embodied carbon is of the building. So you may wonder, what does EPD stand for?

EPD is an Environmental Product Declaration, and it's a document which transparently communicates with environmental performance or impact of any product or material over its lifetime. And what does LCA stand for? Which is a life cycle assessment is a process of evaluating the effects that a product has on the environment over the entire period of its life, thereby increasing resource use efficiency and decreasing liabilities.

So how do we achieve this for your Revit workflow, you want to determine the LOD, which is the Level Of Detail. And this is something that you could put into your BIM execution and meet with your teams before actually inputting any information into the Revit model. And you can see that there's different LODs going from really low to really high, LOD 100 being low, and LOD 500 being high. And there's other LODs for other disciplines. I've concentrated on architectural and structural because of the 2030 and the 2050 Commitment here.

So actual Revit workflow. Our Revit workflow will yield results of different studies in different areas, such as solar analysis, shadow studies, heating and cooling, energy analysis, and MEP calculations. And solar analysis, it provides in-context solar radiation analysis, which helps track solar energy throughout your design.

So you can see where the sun is landing at all times in your building and you can do a solar study for it. And similar to shadow, you can also demonstrate the shadow's impact from the proposed development. And I've been in cases where a building has cast too much of a shadow, and that building hasn't gone ahead.

Heating and cooling loads are a measure of energy to be added or removed from the space by the HVAC system to provide the desired level of comfort within a space. Energy analysis-- this tool allows professionals to create more energy-efficient designs by running simulations on the proposed model to anticipate and understand its energy performance. MEP calculations, which is to design mechanical systems to meet the heating and cooling demands of the building. Knowing how much lighting to provide in spaces calculates specific piping sizes for the systems created.

And here's what you can actually get out of your Revit model. So here's some models that have been created, some studies that have been created, such as your solar analysis, shadow study, heating and cooling, your energy analysis, and MEP calculations. So before you jump into the Revit workflow, you have to prepare your DWG. Your DWG workflow entails the following steps.

And the objective of this workflow is to prevent corruption of the Revit file and accurate project location. So we need an accurate cadastral file, which is provided by your civil engineers. And you're going to have to verify if the file is in grid coordinates or ground coordinates. We prefer when we're linking in the actual file that it should be in grid coordinates.

But if you're doing specific topography, then you might need it in ground coordinates. That's totally up to you. But I prefer working in grid coordinates. And then you want to clean up the DWG file, delete as many layers as possible, blocks, patterns, and then you want to purge, and audit. You want to move all your linework to the origin of 0, 0, 0, and then you want to-- this is an optional step-- you might want to Copy and Paste your linework into a new DWG file just to prevent corruption if you need to.

If you find that sometimes when you go to zoom extents, it doesn't zoom in to your specific linework but extra space around, and you can't find an object lingering in space, chances are your file is corrupt, so you might want to Copy and Paste your linework into a new DWG file and save it at that origin point of 000. And then you're going to take that and you're going to link that into Revit itself. And now, this shows the cadastral file. This video will pan across the cadastral file and show you how big it can be and how much information it has.

So our objective is we want to get down to the area of our actual plot area or the plot line of the building we want to create. And you'll notice there's other information here which we need to purge out such as lot numbers, there's gas lines. And you'll notice there's numerous layers here. So you want to try to merge all those layers into one and try to merge it all onto layer 0.

That's usually what I try to do without any color. Make sure you thaw and unfreeze all the layers to make sure they all merge onto one. And you want to take all the line work off of the z-axis. You just want it on a 2D plane, which is your x and y plane. So when you link it into Revit, there's nothing on the z-axis because that can prevent corruption. And, again, if you do need those topo numbers and you need anything related to topography, you might want to keep the stuff for the z-axis. But you might want to save that out as a separate file just to prevent corruption in your Revit workflow.

And then moving onto the next slide here, we're going to talk about grid versus ground. So I've mentioned it a couple of times, and grid is actually just your longitude and latitude calculated. Your ground distance is actually entailing with your topography. So I prefer to start with grid coordinates and making sure your cadastral file is in grid coordinates. And you only want to use ground when you have topography. And you want to verify those coordinates with a civil engineer, and your elevation level with a surveyor.

And here, you'll notice this is a different project, but this is a project we're going to be using for the demo itself. And we want to isolate the property line. You see I have property line highlighted there. And I'm going to merge everything onto layer 0 and get rid of the extra layers. Since this session entails more Revit workflow, I haven't demoed as much in AutoCAD. And so I'm going to be outlining those steps in the class handout, and you can refer to those steps whenever you're cleaning out your AutoCAD file.

And again, you want to make sure that nothing is on the z-axis, so that's why I had checked if there was anything on the z-axis. It looks like everything's on the 2D plane. And you want to choose an intersection or align on your actual plot line or property line, and to link it into Revit itself. And this is the cleaned-up file itself, and what you'll notice is that I've chosen the bottom-left corner of the actual property line, and that's the Northing and Easting I've chosen.

And I've created a circle, and I've listed the Northing and Easting on the elevation. So when this file is brought into Revit, we're not looking for the Northing and Easting numbers. It's actually calculated. And we've taken this point where the Northing and Easting was those numbers, and I moved it to the Revit origin of 0, 0, 0. So the point in the bottom-left corner is actually 0, 0, of AutoCAD.

So you want to keep these numbers on hand. And so you want to reference them when you're inserting it into Revit itself, and when you're inputting the Northing and Easting at the elevation. And as well as you might want to highlight and have one of the dimensions ready in your AutoCAD file, so when you link it in to make sure that you've linked it in properly and you haven't brought in the wrong units such as millimeters or meters. Sometimes the automatic detection of Revit will bring in the wrong units.

And jumping into the Revit workflow itself, there's three steps that I'll be going over, which is we're going to be setting the Northing and Easting location, the elevation, and we're going to be setting the True North, and Project North. So this is essential to a sustainable design workflow. Once we set this information, we can create those daylight studies, we can create those solar studies, we can do an energy analysis, we can actually even do wind studies.

So this is why it's pertinent to locate the actual building in the real-world coordinates of where it's located. And this is the following steps. We'll show you how to do that. So we're going to define positioning. So we're going to link in the DWG file which we just cleaned up. And you'll notice that now I'm in Revit here. And what I want to do first thing is make sure that my project base point and my survey point is visible. I'll be using those as a guideline and we have to set those up later for the Northing and Easting location.

So I'm going in to link the actual Revit, the AutoCAD file itself, and I'm leaving unchecked Current View Only because I want it to come into every view and uncheck that Lines That Are Slightly Off Axis because I don't want Revit to force those lines to go straight which are not supposed to be straight, such as those angled lines. Here, I'm taking a dimension to make sure that the units have come in properly. And that's where the last slide will come in handy and you can verify these numbers.

And once you verify that dimension, you can just delete it out. And then what you want to do is you want to move that origin point of AutoCAD that we had at 0, 0, 0, we want to move it to the Revit 0, 0, 0, point. So we want to align it. And the thing about the project point, and base point, and the survey point is when you zoom in, it keeps going away, so we want to draw a line so we can snap to it. So that's why I snapped to that line and then deleted it out.

And then here, we want to pin the file again, so when we use the file, it doesn't actually move and jump on us. So now we're going to be naming the site. So the benefits of naming the site is it lessens questions, and it makes the team self-sufficient, and it creates an ease of linking in Revit files. It prevents coordination errors. And if we're in a cloud project, we can actually acquire and publish coordinates. And we can do that in a cloud and a non-cloud project.

And you can see here of the default of Revit, it has Survey Point Internal, which is the image to the left. In the image to the right, you'll see that I've changed it to EDM School Site just because I'm from Edmonton. The coordinates I've chosen, the Northing and Easting location are a place in Edmonton or around Edmonton, so that's why I've named it EDM School Site. So in the future, if any team goes in and wants to link in that file, they know which site to use to grab those coordinates.

And so here, I'm demoing how to rename that site file. And you'll notice that I'm grabbing onto the survey point just to show you what the default is and it's going to say Internal Survey Point, so we want to rename that. So now we're going to go to Location on the Manage tab and go to Site. And under here, you want to Duplicate because we don't want to Rename with the Internal. We want to create a brand new one. And we're going to call it EDM School Site.

And once we do that, we're going to make that the current. And you'll see that the site will actually change to that when I highlight it there. So let's just grab the survey point, and then you'll see that it's called EDM School Site. And then after that, just make sure that when you're linking in the file in the future that you're grabbing onto that same site name instead of the Internal.

So setting the Northing and Easting, that's essentially the longitude and latitude in the world. And so it's where it is in the world, so that has a major effect of where we place our actual model. So if we have a model here in Edmonton, for example, and we're doing a daylight study, here, during the summer, we actually don't have sunset till about 9:00 or 10:00 PM. Whereas if you go up North, sometimes the sun doesn't set for six months in a row. So the daylighting analysis for Edmonton versus up North will be very different. So that's why it's essential that we set the longitude and latitude, which is equivalent to the Northing and Easting location in Revit.

And the benefits of this is to establish the real-world geographical location of the building, and we want to create to have coordination accuracy. It ensures accurate positioning of the building or project within its intended location on the Earth's surface. This is essential for accurate representation and analysis of the structure in relation to other geographical features. Site analysis and planning. It allows architects and designers to analyze the site more effectively considering aspects like solar orientation, wind patterns, and surrounding terrain.

Visualization and simulation, you can do that as well through the actual model. And the geographic coordinates allow for better visualization and simulation of the project in a real-world context, provides a better understanding of how the building fits into its surroundings, and influences design decisions.

Here in this one here, we're setting the Northing and Easting location. And what you'll notice is that I'm making sure that the DWG is pinned so it doesn't move around. And that's essentially because when we grab the survey point, things are going to jump all over the place and you're going to notice that. And you want to make sure that your survey and project base point are turned on. And so when you unpin the survey point and just move it around, the numbers and values are not going to change unless you actually unclip it, and then you'll notice the value change.

So you'll notice here I'm going to filter it again, and I'm going to grab the survey point, and then I'm going to unclip it. And then we can actually put in the numbers. You've noticed here that I've taken more than a few seconds to actually input the numbers in. So you want to go back to your sheet from before or the slide from before and verify those numbers. Essentially, you can change it again-- your actual Northing and Easting locations-- but it's best to keep it consistent just to avoid the corruption element of Revit itself.

So the numbers of the Northing are going in right now and the Easting location are also going in. So those are the only two numbers we're going to input. We'll do the elevation later. And you notice the survey point is no longer there. It's jumped. So it's jumped up to the actual coordinates of where it's supposed to be according to the real-world context, but the actual project itself is still in the same place. We still have to relocate the project with the same information of the Northing and Easting location, and in order to do that, we're going to grab onto the project base point.

For this one, we don't have to unclip it. We just have to unpin it. And that will be forced for us when we actually choose Relocate Project Tool and you see that little pop-up there. And when you actually move the point, you can move the point to over the survey. And make sure you're using your tab on your keyboard when you're overlaying it. So you see that little circle that had popped up? That means that it was right off over top of the survey point. And now what we're doing is just making sure that project base point numbers match with the survey point.

And here, we're going to take the survey point and the project base point, we're going to make sure that we pin and clip both of them. So you see I've pinned it. But when you go back, you can't actually clip the survey point. You have to make sure they're both unclipped, and then you can clip it, and then you can pin it, and then that's how the steps of actually setting your Northing and Easting locations.

And we're moving on to elevation and how to set the elevation. So the elevation is the actual vertical height of where a building is according to sea level. And, again, that's important for all of our studies such as daylight analyzing, shadow studies, wind studies, to where the actual building is located. And the benefits of setting your elevation are it provides vertical positioning.

And it provides information of how high or low a specific point or element is above specified reference point, usually a datum or sea level. This represents the building's vertical position. And then another benefit is the topo surface. We can create the site plan effectively according to the geodetic location instead of the architectural levels. And then we can also provide 3D modeling and clash detection. So we can take the elevation data, which is used in 3D modeling to accurately position and align elements vertically. It's critical for clash detection to identify and resolve conflicts or interferences between building elements.

So here, we've set the actual elevation, but we want to make sure that the survey point doesn't have anything set ahead of time, so the elevation is still at 0, 0. So to set the actual elevation, we actually have to go into an elevation view. So I'm going into the East elevation here, and I'm just grabbing onto the survey and project base point, and just reminding you that how to turn on the site, and how to turn on the survey point and the project base point.

And just remember, I have no template on this Revit project, and I'm not using any specific add-in. I'm just using out-of-the-box Revit. And here, when I change the levels to Architectural and Geodetic, you'll notice that nothing is set up here, and that everything is just at 0, and that when I change it between the architectural level and the geodetic level, that it stays the same.

When I use the tool for project relocation, it forces me to unpin, and I can input in a number of 700 meters-- again, going back to the slide from before for the elevation number-- and the project actually jumps similar to the survey base point earlier. Here, you'll notice that it has the actual elevation number in there now. And when you click on the actual level itself, you'll notice that it will change to the actual geodetic location.

So before I do that, I'm actually taking the dimension and making sure that the actual elevation is accurate, so we've actually moved it accurately to the real-world coordinates of the 700 meters. And then we can actually delete that dimension out. We won't need that anymore. It was just for our reference. And now we're switching it to the actual geodetic elevation, and it changes to that 700 meters.

And then same with the level 2. And then when we change both of them back to Architectural, they should change back to the 0 values again and the 4,000. And then what we can do after we're done is we can actually just pin the project base point again. And then lastly, we're going to do the Project North for the Revit workflows, and we're going to set Project North. And but before we get into that, we have to understand what's True North versus Project North.

And here's a little slide to explain Project North versus True North. So Project North is design-oriented orientation used within the Revit model. It's used by architects and engineers to have a horizontal and vertical, a straight up-down 90 degrees, and as well as a straight vertical as well, so we can know which orientation we're modeling at all times. For True North, that's critical to set it because we want to have a broader analysis of our actual project because not all projects or not all buildings are straight.

They can be at an angle or they're aligned. And they could be at a North East location. They're not always straight either in like True North or they're not fully West or they're not fully East. So for True North, it's crucial for aligning the building with the broader accurate geographic context in the real world with site-specific factors. So setting the True North actually allows for accurate analysis related to solar exposure, wind patterns, and other specific factors.

So here, you'll notice that the orientation of the actual building is in True North right now. And what we're going to do is set it to the actual True North right now. It's pretty much up and down, and that's going to be our Project North. So we're going to rotate our True North to what it's actually supposed to be. So in this case, we're just going to be rotating it 5 degrees.

So when we call up that tool of rotating the True North, it forces us to unpin that survey point, and then we rotate it that 5 degrees. And then, again, we just take that survey point and we pin it again. And then when we switch it between True North and Project North, you'll notice that it actually shifts, so to what it was before. And then when we have that 5-degrees turn, it's going to switch to that True North location. So again, Project North and then what was True North.

So just a reminder of what we can actually create from those different studies and analysis when we set the actual Northing and Easting, the elevation, and the True North as well. So we can create the solar analysis, shadow studies, heating and cooling, HVAC calculations, MEP calculations. And you can see here, these are some finalized models that have been created, and they're actually very in-depth studies. And you can see in the solar analysis, you can actually see where the sun falls during the day and what times of day. And you can see where the shadow is cast on the shadow study.

Here's an actual project that we did at DIALOG, and you'll notice that the calculations are in lux. So lux is a light measurement. It's a light intensity. It's light intensity in a specific area. So the stronger the lux, which is the yellow color, is 6,000, and the lower it is, the darker the color which is the maroon color, which is 0. So you'll notice at the North orientation, which is, I consider, the back of the building it's darker there Whereas the front of the building has more light at this time of the day when the analysis was taken.

And when we actually look at the building itself inside, we can actually do also a lux analysis at certain times of the day to see where and how much the light is falling. So you see that it's darker in the lower levels of the building and lighter in the top, just because of the clerestory windows. And as well as the windows at the back where there's light coming in, it's a little bit lighter there too.

And here is a side-by-side analysis of two different times of day of the same building interior, but providing two very different lux scales. So here, you'll notice that on the left side that there's not very much lighting coming in at this time of the day. And then on the right side when it gets more around noon or 1:00 o'clock, there's actual more lighting coming into the building.

And you can actually take this even further. You can do studies for the outside of the building. And you can do actual rendering if you have the correct material inputted. And you can see the reflections off of the material and see not only shadow studies, but you can test for reflectivity as well. You can see that there is actually a reflection of the tree and it might be blocking the light as well.

And here is a nighttime analysis of the same building. You can see how the light is being projected outward, and how the surrounding areas actually have an effect on the building itself. So for Revit family setup, that's connected to your Revit workflow itself, I'm going to be showing you how to set up an actual Revit family. And I'm going to show you three examples, and one is incomplete, one is partial, and one is complete. And you'll see how the effects of the data inputting into the Revit model itself and what we can actually output. We'll be doing material takeoffs for that example.

So here's an example of a wall that has incomplete information. So here, we actually have a generic wall that's 100 millimeters. And you'll notice that even the naming convention doesn't actually show any information, and when we go into the Edit assembly in the structure itself, that it has no material assigned to it. Even in the preview itself, it has no information and it's not listed. So going into actually drawing the wall and then selecting it again, we're just taking a look at the actual information in the Identity Data. There's no information inputted here. There's no cost. There's no manufacturer. And there's very minimal to actually, no information.

So from there, we're going to do is do a material takeoff. It should be no surprise that since there's no information, we're going to be actually outputting no information. So we're creating a material takeoff and you'll notice that there's different aspects of material takeoffs that you can do, and there's a lot of available fields that you can choose. From Family and Type, you can actually see what family you're using, to Material Area to Cost to Manufacturer, the actual Mark, the Model, and the Name as well.

So the material name, in this case, won't even help us because we actually have no material listed in it. So there's going to be no information yielded, so that's why I've pulled the family and type information there. So the mark will show up if we input that in as well. So you can see that there's only an area that has been pulled and it just says generic wall, so we can't take any type of takeoff off of that information.

Here's an example of a wall with partial information. You'll notice that it's pretty much complete, but there's just a couple of elements missing which I'll highlight when I'm sharing the video. And so the actual wall material takeoff that we have will have almost all the complete information, but it won't have the cost, and it won't have one of the materials.

So here's an example of that wall. So you'll notice as soon as I put in the wall it looks very promising, as in you can see all the different materials drawn out here in the rendering. And when we go into click on it and we hover over the properties, we actually have more information available for us already in the preview. And then when you go into Edit Type, you'll notice that there is actual width of the wall, which is actually 424, which is not a fully round number because it actually has materials in the information.

So I want to highlight point number 6 in the actual table where it says Substrate 2, and it just says by category. You'll notice that in the material takeoff schedule, and you'll notice that'll be empty or also default, so that's why I'm highlighting that right now. But all the other materials will show up in the material takeoff schedule. And in the material takeoff schedule, you'll notice more complete information, and as I said, cost will be missing. So I'm just trying to create a similar material takeoff as before. We're going to be taking information such as the Family and Type, and we're going to be taking Material information.

Actually, like the material takeoff schedule is better than the actual area schedules because you can actually take all this information from the identity data, and you can have more complete information. And you actually might want to use the Material Comments to specify to the person grabbing the EPD or LCA that, OK, that material is not available as an EPD in Canada, but you may use something else that's available.

Here, you'll notice under the first line on the schedule it says Default Wall. That was what I highlighted in the actual edit properties of the wall that was not defined as a material. And you'll notice the Material Cost is also empty because we have not specified any cost. So once we take out the family material, and cost, we can have a more refined schedule as well to actually show you just the area and just the cost. And again, that Default Wall is still empty, and the Material Cost is empty there.

So moving onto the wall that has complete information. This is a little bit faster because we've gone through two demos already. So this one is a wall that has all the materials listed here and all the categories. And you'll notice all the thickness is specified and all like the functions are specified as well. So when we calculate the actual material takeoff schedule, I have associated costs with it. Obviously, aerospace won't have a cost, or hopefully, it doesn't have a cost, so that's why it's listed as 0.

So moving onto the overall message of why we actually have to assign specific materials to your Revit families is it actually contributes to our embodied carbon. So one piece of advice that I got from my fellow DIALOGer a while back was in this statement here or in this quote here, she actually mentioned to me that, "Incorporating the correct metadata within Revit workflow, project, and families is critical for the usable output data. It influences the ability for the project team to accurately use that data for embodied carbon analysis and for those teams to make an educated decision on embodied carbon reduction strategies."

And Stephanie Fargas is the one that had shared this information with me. She's an associate at DIALOG, and it actually, as I was creating the sustainability design workflows in Revit, I noticed whatever you actually input, and depending on what LOD you choose, is actually what you can extract. And hopefully, through my presentation, you've actually seen all that demoed. And if you have any questions, please reach out. And here's to committing to net zero and to having proper Revit workflows, and proper working within Revit, and Revit families itself.

And I'm leaving you with a closing thought by Kenyan social, environmental, and political activist who founded the Green Belt Movement. She empowered women for planting trees, so through that, she was solving a lot of grassroot problems, such as not only empowering women, and as well as helping the environment. The quote is, "The environment and the economy are really both two of the same sides of the coin. If we cannot sustain the environment, we cannot sustain ourselves," and that's by Wangari Maathai.

And I'd like to encourage you, as you leave today, to not only make a difference in your workflows within Revit, but on your job on a daily basis, and as well as at home in your domestic lives. Thank you very much.
