Unlocking Building Electrification: Use Systems Analysis and Insight for Strategic Design and Analysis

GIUSEPPE ARDITO: Hello, everyone. And welcome to our Autodesk session about Unlocking Building Electrification, using Revit System Analysis and Insight for Strategic Design and Analysis. So, I want to just point out before starting our presentation, a few other courses that Autodesk University, that they cover the content related to our presentation. These courses are part of the Autodesk University 2024 unofficial Sustainability and Carbon track.

Now let's start to talk about building electrification, why we're focusing on building electrification. The built environment notoriously contributes 40% of the global greenhouse gas emissions. And the ISE industry naturally has a responsibility to reduce these emissions. And the building electrification is one of the many potential option to decrease the carbon emissions of new and existing construction.

So in this AU session, we will take a closer look of how we expanded and automated existing Revit system analysis capabilities to demonstrate new building performance analysis techniques. And these techniques can be used to increase our understanding of operational carbon impacts and our design. So we start out our intros. I'm Giuseppe Ardito, and I'm a Senior Product Owner at Autodesk with a background as sustainability consultant and building energy modeling specialists. And hand off to Chris.

CHIS BALBACH: Hi, everybody. My name is Chris Balbach. I'm Director of R&D at Performance Systems Development of New York. I'm a mechanical engineer with a lot of OpenStudio experience.

TETSUYA HISHIDA: Hi, I'm Tetsuya Ishida. I'm also an engineer. And I'm now taking care of Revit MEP design as a product owner.

GIUSEPPE ARDITO: I won't go through the learning content learning objective in details. Instead, let me just summarize what Chris, Tetsuya, and I aim for this AU session. And we just hope that this AU session is going to be a hands-on course for advancing your use of Revit Systems Analysis. We will provide electronic access to all the files and examples we cover today. And our goal is for you to leave this session eager to apply and maybe even expand on this workflow in your everyday work.

So here is what we are going to plan for today course. So we will start with an overview of the system analysis, features, and capabilities and conclude with a discussion of future developments and next steps. In between, we will review last year class, cover the latest update to the Revit add-on for building electrification, and demonstrate two new system analysis workflow. All these materials, as I mentioned, we will share via file transfer, along with a more detailed leave behind documentation.

So let's have an introduction about the Revit system analysis. So the first part of this session, as we saw in the agenda, covers an overview of Revit Systems Analysis. So Revit Systems Analysis is a set of features and framework in Revit that enable HVAC design engineering and analysis workflow to be conducted in a significantly more collaborative, integrated, open, and extensible way. This approach enhance how team works together and how the system integrates with other tools, providing a more flexible and comprehensive analysis environment.

So in today I see industry, we have experts specializing in architecture, building envelopes, and structural design, as well as those focused on HVAC system, including design, sizing, energy, and comfort analysis. Typically, these two groups operate separately, with many engineers relying on third party tools for their daily tasks. Since its release, Revit Systems Analysis has been working to bridge the gap between integrating the two areas and the respective tools. It leverages Autodesk features to enhance BIM collaboration, improve Revit modeling for energy analysis, manage space and surfaces, and support HVAC equipment and plant selection. Additionally, it provides tools for analyzing energy use, thermal comfort, and energy cost consumption.

To illustrate this, let's start with the first step of Revit Systems Analysis workflow, modeling in Revit. In this phase, users prepare their input data by defining several key elements within the architectural model. These include project location, massing or geometry, material thermal properties, rooms, analytical spaces and their function, and HVAC systems. Once this data is set up, user can initiate the analysis with a click, which generates additional data for the review.

On the analysis side, system analysis report results in two many categories, energy metrics and HVAC metrics. The energy metrics include annual and peak energy results, with the option to delve into data at the hourly and sub-hourly levels. As a default, analysis run on 15 minutes temp steps. HVAC metrics, on the other hand, provides insight into the sizing and loading aspects of the design HVAC system.

Now let's take a look at what I mean as a quick class recap, what I mean, we started implementing in terms of building electrification and how we are adding today. So quick recap from last year's session, under the Earth System Analysis workflow consists of six key steps, designing so creating, I mean, the initial design and requirements, modeling the Revit, so developing the detailed model within Revit, measuring, so using the GbXML schema to export the model, which becomes like our source of truth for our analysis, assessing, utilizing OpenStudio to analyze the exported model, running simulation through EnergyPlus, and reporting those simulation, presenting the analysis outcome in a system analysis. To introduce a new decarbonization workflow, we integrate a customized OpenStudio measure into Revit Systems Analysis process. But for instance, last year, however, for this OpenStudio measure to function correctly, they require additional data that it wasn't available in the Revit user interface. Instead, this data was managed through user editable CSV file.

Today we have automated the entire process. And the decarbonization workflow are now seamlessly integrated into the Revit user interface through the add-on. In addition, those workflow have served as a foundation for insight, particularly in defining factors and simulation. And now I'm going to, after this quick introduction regarding Revit Systems Analysis and a recap of last year class and providing a latest update of the automation of the add-on, I'm going to hand off over to Chris that is going to basically talk about new construction workflow in terms of HVAC sizing.

CHIS BALBACH: Thank you, Giuseppe. So yeah, we're going to spend the next few moments talking about how we could use the Revit Create Decarb HVAC add-on for both new construction and retrofit energy analysis, building performance analysis. But let's take a step back first. Let's talk about what we're seeing.

What we're really seeing here is decarbonization in action. Where I live in New York State, New York City, for example, there are now laws, Local Law 154, for example, is a law that controls the emissions related to new construction. So effective in 2025 now, we can no longer get new permits for new boilers or new water systems that are not electrically powered.

And it's a real thing. Decarbonization, we've been talking about it for several years, but we've actually moved from talking and planning. And now we're actually entering implementation here in New York State and New York City.

Here in New York City, we also have a law, Local Law 97, which is aimed at existing buildings, existing buildings greater than 25,000 square feet. For those buildings, there are now emission caps. CO2 emission caps have been set on a building by building basis. And effective in 2025, there's going to be fines applied to buildings who exceed those caps.

Again, these are rolling out over time for the buildings that are covered under the caps. But it's no longer just talk and discussion. It's actually real at this point here in New York State and New York City.

What this means for us is that it's not just New York City. You can see here from the slide, that New York State, California, Washington State, Colorado, parts of Europe, parts of Canada, parts of Australia, new construction in existing buildings, this is a wave that is occurring across the world, where ordinances are being passed. They maybe they have been passed, and now they're being implemented all in the aim of decarbonizing our built environment, new construction and existing buildings.

What does this mean? Well, what this really means for building performance professionals is that there's a new opportunity to provide services, a new service opportunity for decarbonizing and the planning process associated with that, again, both for new construction and existing buildings. These projects will need to be analyzed. There'll need to be solutions derived, there'll need to be plans put together for the capital to provide for those projects. There's a whole lot of work happening and will be happening globally.

Now historically, Revit's played a very important role in that work. Many of you are familiar with that work in terms of design and engineering and architecture. But we're really entering into a whole new planning process of again, decarbonization planning process for new and existing buildings. How do we decarbonize those structures and electrify them?

When we really consider the new construction market, we look at a couple of things for building performance analysis. And Revit has been able to provide feedback for some time, some time, many years in terms of equipment sizing and peak energy use by Revit's, load calculation procedures that have been built in since about 2021. What's different now with the release of the add-on or the integration of the decarb HVAC add-on is now again, we can add energy simulations to the package of services.

And those annual energy simulations allow us to predict annual energy use and actual annual energy costs associated with different HVAC systems.

| why is this important? Because we're going to have to again, provide feedback to the two owners of which systems do we recommend, and of course, what are the impacts of those systems.

Now, the real power in Revit is not just providing feedback on the performance of different HVAC systems, but also this complex interaction of HVAC systems and building envelope. So yet another dimension of analysis that's available within Revit, within the Revit environment, is the ability to provide equipment-sizing information, peak energy Information, annual energy Information and annual cost information not just for different HVAC systems, but also for different envelope systems and the combinations of those two. Of course, in new construction, we can pick what the proposed envelope and the proposed HVAC system will be in the context of a retrofit. We may have an existing envelope. And we'll have to pick an HVAC system that may work with that envelope to fit the existing constraints.

What's new here with the HVAC add-on that we have developed and delivered is that that information is now a part of the Revit model. And the output reports are included in the Revit data model as analysis reports. We can run annual energy simulations. And we can extract the information needed to give us that information, sizing, energy use, peak energy, use and annual energy costs for different combinations of envelope and HVAC system performance.

Let's talk this through a little bit more detail with a real example or an example of a typical multifamily building that we might find in, let's say, New York City, where the carbon mandates are in place. New construction-- we must again in New York City, all electric building, new construction, multifamily building. So imagine we're in, let's say, a conceptual design or maybe even schematic design phase of a multifamily building. And we're looking at a possible proposed building design that's a high performance envelope, triple pane windows, a high performance window assembly R-value. We know we have all electric appliances. What about the HVAC system?

Perhaps one of our proposed HVAC systems would be a system like described on the slide, which is a water loop heat pump system, where we have ventilation, energy recovery. We have cooling towers on the roof of the building, and we have electric boilers in the basement of the building, both conditioning a water loop. That's a possible system for new construction that would meet a local law, Local Law 97 and Local Law 154's requirements.

This building we're going to look at, it's 44 stories tall. It's 440 units. And it's a large building. And we really, we want to be able to analyze the performance of this building as early as we can in the analysis process.

So we want to use this add-on to answer questions, maybe a question like this. Can we use this add-on to estimate the energy and energy cost differences between two different HVAC system options, an energy code compliant four pipe fan coil unit option and the water loop heat pump example we just saw described in the previous slide. Can we use the add-on for this? The answer is yes, we can.

Now again, you'll see on the right, a model that was built in Revit. This is a model that was built using masses, conceptual masses. So it's built at the phase of a project when you understand information during the conceptual design or schematic design phase. And we can still again, apply this information to that Revit model to glean additional information.

Now, using the decarbonization HVAC add-on really requires us to think about a workflow. And this is the recommended workflow that we would recommend using. I'll note here that Revit Systems Analysis is a key part of this. So we start with Revit itself, creating a minimum viable model, a Revit model with the information we know at the time.

Then we use Revit Systems Analysis capabilities for steps 2 and 3, where we create an Energy Analytical model. And we QA that model to make sure that it is being built to represent the information that we expected it to carry. Finally, in step 3, we use again, Revit Systems Analysis to create some placeholder HVAC system information that the add-on will override in subsequent steps.

Steps 4 through 8 in the green, those are add-on steps. So we would launch the add-on from inside of Revit, and we would configure the add-on with some information. Down to step 7 and step 8, where we would simulate a model, generate the report that we showed on the previous slide, and quite possibly, quite probably, we would iterate. So again, a stepwise process that we're recommending here, including iteration as necessary.

Now the add-on, the HVAC add-on has a whole lot of assumptions under the hood that are not exposed as user inputs in the add-on itself. And I want to point out that all of those assumptions are visible. The underlying OpenStudio model that is used by the add-on is available for extraction. And users can open that model up in a tool called the OpenStudio application. And they can see, they can transparently inspect all of the assumptions used to create these results.

That's really important because again, the add-on may ask 10 or 15 questions while there's 150 or 1,500 assumptions being made. And we want to make sure that people feel comfortable with those assumptions that are underpinning the analysis from the add on. Let's just watch a quick video here, showing an example of new construction analysis done for the multifamily building in New York.

We'd start off again, by building our conceptual mass model. We would then configure Revit's energy settings here to make sure it's using the conceptual mass properly. You'll note we created a custom building type for this New York City multifamily building. We then go again, and we create an Energy Analytical model here using Revit. And we QA that model. We want to visually inspect that model, both the spaces and surfaces to make sure they are what we expect.

If they're not, we regenerate. Again, that might be iterative to get the model that we want. Once we have that model, we again use Revit Systems Analysis to make these placeholder HVAC systems that are going to contain the topology that the HVAC add-on will use. So we see that done. We launch the add-on. And then we start configuring the Add on for the HVAC system that we want to model.

We also can configure some add on overrides for the particular system that we want to model. Those again, are optional. If not, it'll run with 90.1 compliant inputs. We configure a tariff as well, the cost of electricity, including energy and power. We provide a custom report name as part of the add-on. And finally, we will run the analysis.

Now, what we're seeing here is the final report after the analysis is complete. And this very detailed report, you can see at the bottom left, is part of the Revit ribbon at the bottom. It's a new analysis report. It's part of the Revit model if you save it. And that report contains all of the information needed, again, to compute the energy cost, the peak power, the actual energy demands over a year, and the equipment sizing information. So it's all contained again, inside Revit, inside the add on if you follow that workflow.

I've shown again, what we want to do is run that workflow consecutively. These are the settings you would set up for the 4-pipe fan coil unit, a different HVAC system. Again, using the exact same envelope, we're looking at the impact of different HVAC systems here on this new construction analysis. And when we do that, we will get two reports. And we can extract information from those two reports that would look something like what you see on the screen here.

It's actually quite detailed information. You can see that the peak energy use is quite different between these two systems. And that would make sense because these two systems are different. One of them is relying on centralized equipment, central boilers, central air cooled chillers. The other is relying on a combination of decentralized equipment and centralized equipment.

So again, pros and cons for these systems outside of tenant comfort and all sorts of other dimensions. But for those very early on design decisions of how big will this equipment need to be, how much power might it need to use, how much energy might it consume, and what that energy cost, we can glean that information out of those reports from Revit with the information we have. Very simple as part of the HVAC add-on.

Now, that's one dimension. again, we mentioned new construction modeling, where we're probably looking at different combinations of HVAC system performance and perhaps envelope performance as well. We can also apply the HVAC add-on to retrofit scenarios. But our constraints are a little different in these cases.

When we look at retrofit scenarios, decarbonizing an existing building, we have different constraints. We probably have limited space for potential equipment, new equipment on the roof or in a basement or where it might be. We probably have limited power distribution in the existing building that we have to work within. And extending that power, of course, costs money. So even just controlling or managing the amount of new power we will need is very important.

And we might also run into this very important concern of what we call split incentives, where the existing building might have tenants, maybe not paying for their heat or their hot water. And in this new decarbonized building, we may be expecting them to pay, in other words, switching the cost burden on to a different user. So all of those things can be looked at again, with the HVAC add-on at the point in the process where we have information at that time.

Also, we can look at extending envelope efficiency, for example, improving windows or improving walls. But that's a much bigger project now for decarbonization retrofits. You're building a much bigger project.

So often what happens in retrofits is we consider staged electrification, where perhaps we only electrify the HVAC system first. And then at some point down the road, we might electrify the hot water system. And then at some point, we're there. We might not do them all together. So the HVAC decarb add-on can be used to examine the HVAC system portion of that project phasing today.

Now the HVAC systems that we can look at using this add-on are quite varied. They include the central plan equipment, like we saw earlier, central boilers and central air and water cooled chillers, different types of loop pumping scenarios, different types of central air to water heat pumps, as well as what we would say unitary equipment or packaged equipment, water loop heat pump, ground source heat pumps, direct expansion, single zone units, and so forth. Many, many options are available in the HVAC add-on, as well as many, many overrides for those specific HVAC system types.

So let's take a look at an example here for a multifamily building in New York, but a retrofit situation in existing multifamily building. A bit smaller, only eight stories tall, only 64 units. And of course, this building has some constraints. For example, no room for additional central plant equipment, limited electrical capacity available in either the tenant or the central areas of the building.

And currently, tenants are paying for their heat. This particular building had a district steam system, where tenants were not paying for their heat. It was included in their rent.

One possible solution we might look at, it's a very popular solution to evaluate is single phase through-the-window heat pumps. We call them package window heat pumps or PWHPs. That's a decentralized HVAC system that would be installed in each apartment. They're quite low in capacity. So again, we might need to look at improving the windows, maybe even the wall, and maybe even managing ventilation systems or managing the ventilation loads in order to find a combination of an HVAC system that will fit all of the constraints that we need to work through here.

And in this case, again, it's important that we have an estimate and an understanding of the utility cost burden. If these systems were to be installed, because we're switching, the cost of heat from used to be in your rent to now a burden on the tenants themselves. So a question we might want to ask ourselves if the add-on can answer here is, can the simplest possible project, packaged window, heat pumps alone, , can that meet our design loads for this existing building?

Or does our project need to grow. Do we need to have better windows? Do we need to have better envelope and maybe ventilation management as well? Can we do that.

Well, the add-on can certainly answer that question. The answer is maybe. We're going to use the add-on to find out. And the question I want to make sure you guys understand is, how? How do we do that?

So to do that, we got to understand the system a little bit better here, the system we're going to evaluate. These are pretty novel solutions. There's some photos on the right side of the slide of this package window heat pump solution.

What makes it unique is you can plug it into an outlet. In an HVAC system, you plug into an outlet. But it's a heat pump.

And because of that, it's a heat pump with no backup heat. So it's very important that the heat pump alone, be able to carry the heating load at the coldest day of the year. You can see here in the slide that at least for 2023, New York City didn't get very cold last year. And historically, it doesn't get very cold. This particular piece of equipment can meet the loads with full heating capacity down to 5 degrees. So this heat pump can carry the load.

That's not a question at the design temperature. The question is, how many heat pumps do we need for a given apartment? And the constraint we're working with here is up to two outlets we could dedicate to package window heat pumps. Will that work? That's really the question we're going to try to answer with the add-on.

So a little bit different here again. We've built a model with a little bit more information than we had before because we know this building. Again, this is an existing building, their drawings, their specs. There's more information than a new construction building in the schematic design or conceptual design phase.

So let's watch a little video where we use that information to try to answer this important question. So again, in step 1 here, we are building our Revit model. And in this case, we did actually use Revit spaces. We built some special spaces to capture, for example, apartment spaces, stairwells, elevator spaces, lobbies, all of those sorts of things. This is not a massing model.

We configure our energy settings inside Revit to use the information from the space types that we built that we assign to our model. And yet again, we are going to create an Energy Analytical model using that space, those space types and spaces. Just like before, we need to QA that model, in other words, make sure that model looks like what we expect it to look like. We'll do that again with a number of different views.

Assuming that the model looks good, the energy analytical model, once again, we're going to build our placeholder HVAC system topology using Revit Systems Analysis. You're seeing that happening right now. In this case, every analytical space is going to be assigned to a placeholder single zone system of a packaged terminal heat pump, size or type. Then we launched the add-on, and we start configuring it.

So very simple configuration here, we're going to look at the HTTP by itself. Later, we can look at adding systems and ERVs and whatnot. But the question is, can we just use the simple HTTP? Will it that work enough?

Here, we're seeing some component overrides being applied for the packaged window heat pump system, for example, the manufacturer specifications of the efficiencies HSPFEER and the manufacturer specification of no backup heat for this heat pump and a manufacturer specification of a size. Finally, we're configuring a tariff that is applicable for this particular building, both the cost of energy and power. And then we launch the add-on, a custom name for this when we launch the add on.

And then we run the simulation, again, all done inside Revit. When the simulation finishes, we will see again, a report, the standard simulation report. And what we'll be able to tell from this report if we see the column I'm highlighting right now, is that each of those zones is quite a bit bigger than 18,000 BTUs, which was the capacity of two package window heat pumps. So unfortunately, we can't get there from here with this particular analysis iteration. We need to go back and look at some other iterations.

Perhaps better windows might get us there. Perhaps better windows with outdoor air management, PTHP with the DOAS and the ERV, or perhaps even with all three of those. We just can't get there from here. Those are the kind of questions we can use the Create Decarb HVAC add-on to answer. And those are, again, the kind of questions we want to answer as soon as we can early in the design process when we're building the scope of a project, for example.

So to summarize the Decarb HVAC add-on, this add-on extends the existing capabilities of Revit Systems Analysis. It does not replace them. It works in parallel, actually in series with them.

This add-on is integrated within Revit. So that's very important because it supports all the collaborative analysis features that come along with Revit. This add-on again, works very tightly. It's very tightly bound to the Energy Analytical model that Revit produces.

And this add-on also produces analysis reports that become a part of your Revit model. They persist. You could have one, two, three 100 different reports if you want to run them. And they will persist until you choose to delete, remove, or extract those reports from your Revit model.

The other important thing I want to point out is that this add-on again, as Giuseppe stated earlier, everything in this add on is open. It's built on top of open source frameworks that allow a user, if they so choose, to look underneath the hood, to inspect the model itself, to inspect all of the inputs used to generate the results, to inspect the algorithms used by the energy analysis tool, EnergyPlus, the physics engine underneath it. There's no black box here for how these analysis results are created. And that's very important to build trust in the results that the add-on is creating.

Finally, there's additional features that we're adding to this add on. We understand that decarbonization is not just HVAC systems. We also want to decarb hot water systems. So service water systems, both loads and the systems themselves, those are under development to be included into the add on in the near future. So stay tuned for that. And again, we look to add electric and non-electric options for both HVAC and hot water to the add-on.

So I'm going to pass control now over to Giuseppe, and he's going to talk a little bit about how the add-on and the features of the add-on integrate with insight for total carbon. So, Giuseppe?

GIUSEPPE ARDITO: Thank you so much, Chris. So with the new measures workflow and the add-on- behind us, looking ahead, what's next? So in terms of software, everything that we presented here in this session is based on tools and platforms that are available today. What's worth emphasizing, is that building models, defining materials, HVAC system and running analysis, Revit System Analysis, is just an initial part of the discovery journey, where the main element is the integration of data and analysis into meaningful insight.

So the measures and the workflow that just Chris described are the backbones of this integration. And meaningful insight become important to clearly communicate the project to the project stakeholders, everything related to key inputs and assumptions in order to build trust, set clear targets, assess mean trade-off between design options and make informed decision. So while existing tools excel in generating granular analysis, they tend to leave the job of creating and communicating insight to sustainability and analyst, which can be very challenging and requires great subject matter expertise.

So to address this and help to scale sustainability analysis to a broader audience, we, at Autodesk, released last April, the next generation of insight. And as Chris already described, in terms of workflow and add-on, those workflow are the backbone for analysis simulation based on different factors of next generation insight. The vision of the insight is to create a user-friendly, collaborative workspace environment, which project teams can use to target design performance metrics and factors in a very open and flexible way.

In this case, I mean, the video that we are showing present a simple overview containing key metrics and factors of energy analysis, account for project-specific factors such renewable energy or energy storage. And then all of these, the different metrics, factor and design scenarios could be brought together in one place and used to explore and explain design decision under this one place. That is the carb-based dashboard.

At this stage at Autodesk, we are really interesting to develop this new platform inside with the great work that Chris expanded in terms of add-on of building electrification of workflow. And we invite everyone to check out the AU class Total Carbon Data Analysis inside to find out more and understand how to get involved in helping to shape the insight development from here. And now I'm going to hand over to Tetsuya. He's going to basically, give us the latest update about what's coming next regarding Revit Systems Analysis.

TETSUYA HISHIDA: All right, thank you, Giuseppe. So I'd like to cover what's coming next in Revit. We've done a series of workshops and identified some pain points. Firstly, HVAC zoning had redundant information. And users needed to figure out which data would be passed to cascading services, such as Insight.

Secondly, even though Revit had redundant information, ironically, it was missing some key parameters, making it difficult to use in real world projects. Thirdly, the creation of an Energy Analytical model was an error-prone process. Lastly, there were some impediments to adopting EnergyPlus and some gaps on the EnergyPlus side.

So we set our short-term goal to focus on clearer, more logical, more efficient zoning workflow for users. And this is a huge thing. So we are partnering with skilled collaborators.

Firstly, of course, this class illustrated how to have enough control over key characteristics to use them in real world scenario. We are pleased to partner with KC. And now we have a mechanism to override the hardcoded characteristics.

Secondly, we are partnering with FenestraPro to have a dialogue to help go through the Energy Analytical model creation. I did another class with Simon from FenestraPro, so please check that one out as well. And lastly, some might have thought EnergyPlus is a heat balance method. Only for annual energy simulation.

However, we see more and more users adopting Systems Analysis, working on top of EnergyPlus for heating and cooling loads. And we are tuning EnergyPlus up together. Also, this is good news for Unicode character countries. There was a mysterious bug, where EnergyPlus failed. All of this pinpointed the error in the Unicode, handling and included the fix in the EnergyPlus itself.

So in the short term, we're aggressively trying to get the work done for HVAC. And more detail about this user experience in Revit is shared in another session called Futures Briefing. I think that's only in person. So that's a perk to be at AU in person.

And this is the last slide, but I'd like to show you the perspective on where we're heading in the long term. So we divided MEP work into three chunks. We defined the system types needed. It might be a service hot water, it might be ventilation, et cetera. Users would define the topologies of the building, and zoning is a big part of it.

Users would place the components virtually or physically. And we want to support analysis of diverse system types, topologies, and components. Revit would be the cohesive domain model to capture the underlying logic of mechanical systems in buildings. The model would, of course, feed into the AC. Data model for much utilization. And I'll pass it to Giuseppe.

GIUSEPPE ARDITO: Yeah Thank you, Tetsuya. I'm going to present what is coming for Insight for the short term and the long term. So we know that Insight itself, has been released last April. And we released Insight based on three main concepts, the concept of a custom dashboard, open metrics, and open factors.

So these three concepts are the key and main components of Insight. And the backbone, so the backend of all the energy simulation running for calculating operational energy data or carbon data, are based on what mean just Chris described in terms of add-on a workflow. So in the short term, we are even planning to expand our platform to integrate advanced factors that are basically triggering more energy simulation.

We are like planning to integrate our platform in with a implementation that are more fully focused on sharing, reuse, those dashboard, collaborating on the same platform. And this is a short term vision that we have on our radar basically. So advanced factors, I mean, the three are simulation, sharing, collaboration. And in the long term, what we are going to basically implement is include Insight in what is the former industry vision. So basically, integrate Insight as a platform with other Autodesk product, for instance, Autodesk Forma, Revit, under the same umbrella. This is a short-term and a long-term vision.

CHIS BALBACH: This is a quote from a user who participated recently in the beta testing of our Create Decarb HVAC add-on. And it's one of the developers of the add-on content. It's difficult for me to express how meaningful it is when I hear that someone actually used the add on in a way that it was meant to be used, that it actually provided them with value. And it's a good feeling.

And last year at AU, we shared a functional, but a much more convoluted and complex workflow for extending Revit's building performance analysis capabilities. This year, we presented improved workflows wrapped within an add-on that provides an improved user experience and additional analysis, results, and capabilities. Next year, stay tuned. There is a whole lot in the works, as I think you've heard from both Tetsuya and Giuseppe.

Having said that, in continuing our important work, it's really important that we continue to hear from you, our users, as to what solutions you need and you want, and to continue to work collaboratively to develop and deploy them. So I'd just like to take a moment to acknowledge all the members of the team that worked on this add-on. It's much more than just Giuseppe and I. It's a small platoon of individuals too many to mention. And I'd like to specifically thank Giuseppe and Tetsuya, our presenters today. So thank you.

GIUSEPPE ARDITO: Thank you very much, Chris.

TETSUYA HISHIDA: Thank you.
