We are receiving this week John Sullivan, Manager of the AEC Ecosystem Development Team in the world at Autodesk, an Apostle evangelizing with his team around digitalisation and BIMification of the AEC sector, allowing the acceleration of adoption of these new processes around the world.

Hi John,

Thanks for accepting this interview and have our readers know you better in France. You’re in charge of the global AEC and BIM ecosystems in the world for Autodesk and you have a dedicated team.

 

But first of all, could you please tell us more about your background, and your experience before joining Autodesk?

I have been with Autodesk since 1993, much of my career has been with Autodesk. My education is as a Digital Geographer and later a Master’s Degree in Computer IT Management.

Before I was with Autodesk I worked as a land surveyor on construction sites. My favorite job was the construction of a lake in the mid-Atlantic region of the USA. To get to the geologic bedrock and to anchor the foundation of the dam we did lot of blasting with dynamite. This was fun.

Another job was with the U.S.A. National Federal Emergency Management Agency creating digital cartographic products – flood insurance maps and other Geographic Information System (GIS) digital database systems.

I also worked for an Autodesk reseller in Washington D.C. for several years. I was a technical support manager conducting software demonstrations: AutoCAD, Civil 3d and AutoCAD Architecture as well as training on PC and Unix workstations and assembling hardware for customers. – that was a while ago.

 

What’s your role at Autodesk? AEC Ecosystems Development sometimes don’t speak to people. What is it really about and how important this is to the AEC Industry and for Autodesk?

Yes, AEC Ecosystem Development is a crazy name.

At the core of what we do is to listen and to try to understand ways that digital 3D modeling may help solve problems for a particular AEC workflow or industry. We describe an industry with all of the contributors/suppliers/participants as an “ecosystem”. These can be project owners, contractors, designers as well as anyone else that may participate in a project. We work to develop ecosystems of digital 3D modelers designers/contractors/consultants that effectively solve AEC design and construction problems.

One example of this approach is work we did with the USA General Services Administration (GSA). GSA is the federal government landlord for the civilian government building tenants.

GSA understood that 3D models (BIM) could help with project cost, project duration and with managing the occupant space for new and existing (approximately 8000) buildings. Our AEC ecosystem team worked with the GSA to create standard GSA BIM room types and standard GSA spaces. We saved these GSA room/space definitions within a Revit template.

We then distributed these templates free of charge to the GSA design and construction project teams (the ecosystem). With this standard data template GSA could capture space information for any project in an expected way and compare the use of space within its building portfolio. For deliverables GSA asked for three formats a.) an IFC file(s) b.) as a native BIM file (Revit in our case) c.) as a dwg file. This allowed for flexibility in supplying vendors. With this standard space information GSA could then ask if the program requested from GSA for a new building matched what was eventually built. With a standard 3D modeling ecosystem GSA can answer questions like this quickly and easily. This is one example of facilitating a AEC BIM ecosystem and is one example of the work our team does. More information on this program can be found here:

https://www.gsa.gov/real-estate/design-construction/3d4d-building-information-modeling/bim-guides/bim-guide-02-spatial-program-validation

Figure 1 Example GSA Standard Space Types

A challenge in understanding our team’s work is that 3D BIM ecosystems develop in many different ways and there are many ways we can add value to these design and construction ecosystems. For instance, writing BIM project delivery policy documents is one approach. Teaching building trades professional’s 3D BIM methods is another, developing BIM technical data standards such as IFC 2×3 or IFC 4.0. is another. These are all avenues to create an effective 3D BIM ecosystem. The variety of the projects we work on keeps the work very interesting.

 

You run a  Team of several experienced AEC professionals over several continents. What do they do and how do they interact with the AEC Industry?

Our team has a variety of experienced professionals including Architects, Civil Engineers and AEC standards experts. We educate clients on what is practical and real for today as well as what can be expected to advance in the next year or two. Our team has worked on AEC projects before coming to our team and can provide insight on existing projects.

For example, one of our team developed a BIM workflow for the Construction Industry Institute (CII). This workflow applied the CII Advanced Work Packing (AWP) procedures to BIM 360. based at the University of Texas at Austin, CII is the research and development center for the capital projects industry. Chuck Mies on our team worked on this project with Cody Austin. This process applies Autodesk BIM technology specifically to this industrial construction workflow (below). In this case we mapped the CII workflow to BIM 360 capabilities to meet the specific requirements of the CII AWP project execution methods, found here:

https://www.construction-institute.org/resources/knowledgebase/best-practices/advanced-work-packaging

Figure 2 – CII AWP Workflow Diagram

A last example is with the Société du Grand Paris. This project is the largest infrastructure project in Europe (68 stations, 200kms+ railway lines, 25B€). Emmanuel Di Giacomo is working this project for us and set up data export definitions for Revit to meet the requirements of this project. This included geocoding views from Revit as a geocoded and an exported dwg file. Emmanuel utilized our Enhanced DWG Export and Geo-Coding Plugin for Revit 2018. This allows Revit to Geo-code views that are exported in DWG file format to meet the requirements for this infrastructure project’s deliverables. This capability is not available without this plugin that is developed by our Autodesk AEC Business Development Team. The plugin is available at no charge from this website:

http://www.biminteroperabilitytools.com/

This plugin was developed by our AEC Ecosystem Development Team. Our team focuses on where we see gaps in workflows in the AEC industry. If we find gaps that we can mitigate, we work to smooth these this plug-in the extends some capabilities of Revit is another way we map Autodesk tools to specific project works flows.

Making these process/technology connections is very important and is at the core of what our team does. For software to be most valuable it needs to work in conjunction with the project’s process methods and constraints. Making this connection is very important to what our AEC Business Development Team does.

 

Is the situation so different between different continents? What is the level of BIM and digitization and maturity of those continents and countries and what is it driven by?

There is a lot of variation on the ways project teams are organized around the world, including what work each team member is responsible for, and the levels of BIM maturity across the continents.

There are also many similarities.

Some general trends from my personal experience are that in the USA, project teams may leap first and then look back to see how well (or if) BIM worked. In the U.K, France and Germany, more planning goes into the decision of using BIM on a project. There is also more focus on open standards such as IFC 2×3 and 4.0 in Europe. Asia seems to be a bit less mature in BIM adoption, but they are embracing BIM now and may advance very quickly.

 

Autodesk is deeply involved in open standards like openBIM, IFC, COBie, etc. And you’re representing Autodesk at buildingSMART’s SAC. Could you tell us a bit more about this important topic? Why openBIM is so important to Autodesk?

openBIM as sponsored by Building Smart International (BSI) is important to our team and to Autodesk because sharing information improves project execution. openBIM facilities these goals and Autodesk supports openBIM. OpenBIM provides a platform for data sharing predominantly through Industry Foundation Class (IFC) files today. A quick review of what we are doing with IFC may help to understand the importance of openBIM for us.

Software with IFC support includes:

Autodesk Revit (Architecture, Structure, MEP, LT)	Autodesk Robot Structural Analysis
Autodesk Navisworks	Autodesk Advance Steel
Autodesk Infraworks	Autodesk Inventor
Autodesk BIM 360	Autodesk Civil 3D

An important IFC capability we offer is our IFC Revit Open Source Code Libraries at:

https://sourceforge.net/projects/ifcexporter/

This capability is unique among the large BIM software vendors and allows users to extend IFC capabilities without waiting for new releases of Revit. There have been 150,000 downloads of this toolkit, and this open source library. IFC is an open format, but modifying IFC for enhancements also is possible through these Revit open source IFC libraries. This allows additions to IFC functionally to be added by anyone that is interested.

Autodesk with BuildingSMART international is in the process of certifying Revit for IFC 4.0 Design Transfer View and the Reference View. Information about this project can be found here:

http://www.buildingsmart-tech.org/specifications/ifc-view-definition/ifc4-design-transfer-view

 

We also support buildingSMART International as a Strategic Alliance Council (SAC) member. This is the highest level of membership possible as a Building Smart International member and allows us to closely support IFC projects for buildings, roads, tunnels and bridges and railways. The openBIM partnership with BSI forms a foundation for of our interoperability activities.

 

 

How far do you think Autodesk’s role is important and will change the way we design, build and operate?

Autodesk plays an important role in the way things get designed and built. Three technology trends come to mind where we (Autodesk) participate and will participate more in the future. These trends are virtual reality, attribute data management and big data.

Virtual Reality/Augmented Reality (VR/AR) are powerful tools, but we are just beginning to use these tools to better experience projects before they are built. Today a great deal of work is going on with VR/AR we fully support this, but VR/AR will become even more important in the future. As the people/technology interface between us and our software improves, the immersive experience of AR/VR will gain more significance and power in communicating a design’s intent. Contracted deliverables may change to digital BIM deliverables or even hologram types of immersive experiences. These kinds of deliverables convey a much richer experience then CAD files or hardcopy deliverables of today.

A second trend is the addition and manipulation of non-graphic information associated with or attached to BIM objects. Depending on what one is responsible for within a project (concept design, construction documentation, fabrication or operations of a facility) the need for text, material descriptions, specifications or other non-graphic information that are imbedded or travel with the BIM objects become increasingly important. As with AR/VR, as the interfaces and storage and manipulation engines improve, this non graphic information will be more freely available as part of the BIM.

As attribution of BIM object’s increase, the opportunity to query or harvest these attributes for meta-statistics on projects will also increase. A wealth of new information and insight in comparing multiple BIM projects will add to better decision making across the AEC design/build/operate collection of industries. I am not exactly sure where this trend in big data will go but I am confident it will be very BIG!

Thank you for taking the time to read this piece. The future of 3D digital modeling is bright and our AEC Ecosystem Team is in the mix of these exciting technology developments.

Les nouvelles technologies telles que l'intelligence artificielle et l'apprentissage automatique peuvent permettre de réduire les retards et les perturbations sur le réseau d'infrastructures du Royaume-Uni. C’est ce que nous indique le rapport de la National Infrastructure Commission Britannique

Parmi les avantages de la mise en place de nouvelles technologies au service de meilleures données d'infrastructure pourraient figurer :

• Réduire le nombre de retards et de perturbations dans les trajets des trains en améliorant la planification de la maintenance et en accélérant les réparations grâce à l'utilisation de réseaux de capteurs et à l’utilisation de l'apprentissage automatique
• Réduire le nombre d'embouteillages sur les routes en utilisant de la signalisation de circulation intelligente et d'autres systèmes sophistiqués
• Répondre aux événements climatiques extrêmes comme les tempêtes de neige et les inondations d'une manière plus coordonnée
• Identification plus rapide des fuites dans le réseau d'eau grâce aux données des compteurs d'eau intelligents
• Augmenter la concurrence entre les opérateurs mobiles et à large bande en partageant des données sur les vitesses de signal et de connexion – en aidant à mettre fin aux services intermittents

Le rapport de la Commission nationale de l'infrastructure que vous pouvez découvrir ci-dessous examine les opportunités que représenteraient ces nouvelles innovations et formule des recommandations pour accroître le partage de données ouvertes afin d'en tirer le meilleur parti.

Il y est notamment fortement question de BIM et de sa mise en oeuvre afin d’améliorer tous les process, la création, la modification et la validation de ces données.

With the global climate changes going on, direct results of our planet reacting to the pains that human beings have created over the last century by overconsuming, destroying and hurting its resources, there’s a strong and real need to take rapid and efficient decisions to heal our world.

By 2050, over 10 billion people will leave in the cities, creating by consequence a strong demand for the creation of smart cities, new infrastructures, buildings, transportation systems, parks, and utilities facilities. Specialists are claiming that 1,000 buildings should be constructed every day to fulfill all these needs. This will also generate an acceleration of carbon footprint, planet natural resources consumptions, taking into account that buildings are already responsible for more than 50% of these climate disasters.

With these huge challenges, humanity has to find fast and viable solutions to overcome these challenges and get back on the right track for a safe, pure and well-being place to live on our earth.

Therefore, we have to find new ways to design, build, operate and maintain our built environment which will allow us to create new generations of cities, buildings and infrastructures with high performances, able to generate their own energy using sun, wind and earth power to escape from fossil energy trap.

Most countries have understood the importance of what is going on there and important decisions have been made through International conferences like Paris’ COP 21…

Knowing that the AEC Industry is one the less advanced Industry compared to the automotive or aerospace ones and that the amount of investments in technologies positions it at the before last position before Agriculture, anyone will easily understand that the challenge is high.

But the shift has been made now since 10 years – starting in the USA after the big crisis – and BIM Mandates in many regions of the world pushing for the use of BIM processes to reduces Carbon footprints and energy consumption by 20% driving therefore a big demand on the field. The AEC Professionals have started their mutation to this new paradigm.

New ways of production

Building production, whether it’s intellectual or physical is not happening the same way anymore. Especially in pioneer countries like USA, Great Britain, Nordic Countries or Asia.

Whether it’s for reaching International or Local regulations for Building performances like LEED or BREEAM certifications or HQE (High Environmental Quality) or RT 2012 (Thermical Regulation) in France, there’s no other ways than using new process and approaches. BIM is the certainly the most famous one you’re certainly aware of.

Building Information Modeling, a collaborative approach for designing, sharing, building and managing our built assets between all the stakeholders of a project, from the Owner to the architects, engineers and construction companies. The I of BIM takes all its sense when speaking about energy performance as all the analysis, estimations, calculations of performances based on criteria’s are using these data to be performed.

These anticipations can straight away be performed from mobile devices, and can go very simple from sun studies around a building from a mobile device…

Until Solar radiations on your future project, allowing therefore to understand which material will be chosen for a specific façade based on the heat constraints it will face…

Cloud helping climate based calculations

With technologies like Insight 360 a full cloud based energy performances calculation, you’ll be able to make many calculations of several variations of a same project and get the right insights of its performances and behaviours in the real life. Using Energy Models like DOE 2.0 and retrieving climate conditions from climate stations, it will allow designers to take the right decisions, compare several options, evaluate and have the right conversations between all stakeholders.

But not only it will help to calculate future behaviours, it will also allow to evaluate materials quantities, and therefore avoid wastes and selection of the best option to have a sustainable building.

These approaches are both valuable for new constructions, but also for renovation purposes where technology will help quickly and digitally capture existing conditions of a building, so called reality capture, allowing to quickly create a BIM Model of an existing asset and evaluate how to make it compliant with new regulations.

Rapid Energy Modeling, fast and efficient to take the right decisions

Researchers and Energy Specialists at Autodesk have developed what they called REM which stands for Rapid Energy Modeling, using point clouds (coming from drones or laser scanning) or CAD files for the simplest approach to remodel existing buildings. REM includes 3 key elements which are capturing, modeling and analyzing. A BIM Model can be recreated with different LOD (Level Of Details), and once it has been setup and georeferenced, you can get stunning results in the twinkling of an eye thanks to Cloud based energy calculation solutions and see results approaching by 3 to 5% the real energy consumption of the real assets. This can help owners rapidly take the right decisions on how it should be renovated with few means.

This approach has been tested for instance with success a few years ago by the GSA. These new approaches are now coming to Europe where Renovation represents more than 80% of the market in South Europe for example. This is particularly important as there are a large number of historical monuments, demanding a specific and cautious modeling approach for architectural reasons.

 

Generative Design & Artificial Intelligence, the perfect alliance

By using these new approaches, time is being literally compressed and it’s fair as the future challenges are big: 1,000 buildings per day. It’s even more important to find acceleration processes to be more efficient. Autodesk has again largely invested in areas like generative design with open technologies like Dynamo, and by combining it with the power of Artificial Intelligence, it gives the ability to search new ways of designing energy efficient buildings.

Finding the best daylight factor in order to maximize the availability of natural light in the office can take up to seconds, unlike old ways where days were needed.

Energy creation and atmospheric effects anticipation

Thanks to CFD and wind flow simulations, it will be possible to evaluate how much energy a building will be able to generate in a specific location or with a specific orientation. But this will also mean a better quality for users as bad effects like Venturi will be anticipated, like the one for example at the bottom Arch of La Défense in Paris could have been managed before construction. This would have avoided thousands of euros of works to workaround this design error.

But the quality of future interior spaces will be affected by these new trends, allowing the decrease of disagreements linked to bad interior spaces ventilation, too cold air conditioning systems or propagation of bacterial diseases in healthcare spaces. Since early stages of design, it will be made possible to redesign and reposition Systems or spaces themselves for a better life quality.

 

BIM & IoT, a new trend to operate the assets

Optimizing the design and construction process is important to win all these climate related challenges and lower wastes of materials and bad designs, but the key to success will be in the operation and maintenance phase, which represents 80% of the total cost of the building. In that perspective, having a BIM Model to operate in a better way is the first step to success, but connecting it to the IoT will be even more important. This is why Companies like Autodesk have started to deeply invest in innovative and disruptive technologies like Autodesk Forge, allowing the development of ad-hoc technologies and platforms like Dasher, connecting BIM and IoT and allowing to control and monitor any sensor, captors, heating and cooling systems from a BIM Model, out of the fact that it completely blows out traditional heavy systems on the market.

Time is now!

The challenge is high, but beautiful and as you’ve just read it, Government are mandating everywhere, all the resources, innovative new processes and technologies are here, so whether you’re a designer, a builder, an Energy Engineer or Specialist, or an owner, you can beat the expectations and help heal our planet and make it a better place to live for our children and the future generations, and deliver some stunning buildings. So, it’s your turn to play the game!

With the global climate changes going on, direct results of our planet reacting to the pains that human beings have created over the last century by overconsuming, destroying and hurting its resources, there’s a strong and real need to take rapid and efficient decisions to heal our world.

By 2050, over 10 billion people will leave in the cities, creating by consequence a strong demand for the creation of smart cities, new infrastructures, buildings, transportation systems, parks, and utilities facilities. Specialists are claiming that 1,000 buildings should be constructed every day to fulfill all these needs. This will also generate an acceleration of carbon footprint, planet natural resources consumptions, taking into account that buildings are already responsible for more than 50% of these climate disasters.

With these huge challenges, humanity has to find fast and viable solutions to overcome these challenges and get back on the right track for a safe, pure and well-being place to live on our earth.

Therefore, we have to find new ways to design, build, operate and maintain our built environment which will allow us to create new generations of cities, buildings and infrastructures with high performances, able to generate their own energy using sun, wind and earth power to escape from fossil energy trap.

Most countries have understood the importance of what is going on there and important decisions have been made through International conferences like Paris’ COP 21…

Knowing that the AEC Industry is one the less advanced Industry compared to the automotive or aerospace ones and that the amount of investments in technologies positions it at the before last position before Agriculture, anyone will easily understand that the challenge is high.

But the shift has been made now since 10 years – starting in the USA after the big crisis – and BIM Mandates in many regions of the world pushing for the use of BIM processes to reduces Carbon footprints and energy consumption by 20% driving therefore a big demand on the field. The AEC Professionals have started their mutation to this new paradigm.

New ways of production

Building production, whether it’s intellectual or physical is not happening the same way anymore. Especially in pioneer countries like USA, Great Britain, Nordic Countries or Asia.

Whether it’s for reaching International or Local regulations for Building performances like LEED or BREEAM certifications or HQE (High Environmental Quality) or RT 2012 (Thermical Regulation) in France, there’s no other ways than using new process and approaches. BIM is the certainly the most famous one you’re certainly aware of.

Building Information Modeling, a collaborative approach for designing, sharing, building and managing our built assets between all the stakeholders of a project, from the Owner to the architects, engineers and construction companies. The I of BIM takes all its sense when speaking about energy performance as all the analysis, estimations, calculations of performances based on criteria’s are using these data to be performed.

These anticipations can straight away be performed from mobile devices, and can go very simple from sun studies around a building from a mobile device…

Until Solar radiations on your future project, allowing therefore to understand which material will be chosen for a specific façade based on the heat constraints it will face…

Cloud helping climate based calculations

With technologies like Insight 360 a full cloud based energy performances calculation, you’ll be able to make many calculations of several variations of a same project and get the right insights of its performances and behaviours in the real life. Using Energy Models like DOE 2.0 and retrieving climate conditions from climate stations, it will allow designers to take the right decisions, compare several options, evaluate and have the right conversations between all stakeholders.

But not only it will help to calculate future behaviours, it will also allow to evaluate materials quantities, and therefore avoid wastes and selection of the best option to have a sustainable building.

These approaches are both valuable for new constructions, but also for renovation purposes where technology will help quickly and digitally capture existing conditions of a building, so called reality capture, allowing to quickly create a BIM Model of an existing asset and evaluate how to make it compliant with new regulations.

Rapid Energy Modeling, fast and efficient to take the right decisions

Researchers and Energy Specialists at Autodesk have developed what they called REM which stands for Rapid Energy Modeling, using point clouds (coming from drones or laser scanning) or CAD files for the simplest approach to remodel existing buildings. REM includes 3 key elements which are capturing, modeling and analyzing. A BIM Model can be recreated with different LOD (Level Of Details), and once it has been setup and georeferenced, you can get stunning results in the twinkling of an eye thanks to Cloud based energy calculation solutions and see results approaching by 3 to 5% the real energy consumption of the real assets. This can help owners rapidly take the right decisions on how it should be renovated with few means.

This approach has been tested for instance with success a few years ago by the GSA. These new approaches are now coming to Europe where Renovation represents more than 80% of the market in South Europe for example. This is particularly important as there are a large number of historical monuments, demanding a specific and cautious modeling approach for architectural reasons.

 

Generative Design & Artificial Intelligence, the perfect alliance

By using these new approaches, time is being literally compressed and it’s fair as the future challenges are big: 1,000 buildings per day. It’s even more important to find acceleration processes to be more efficient. Autodesk has again largely invested in areas like generative design with open technologies like Dynamo, and by combining it with the power of Artificial Intelligence, it gives the ability to search new ways of designing energy efficient buildings.

Finding the best daylight factor in order to maximize the availability of natural light in the office can take up to seconds, unlike old ways where days were needed.

Energy creation and atmospheric effects anticipation

Thanks to CFD and wind flow simulations, it will be possible to evaluate how much energy a building will be able to generate in a specific location or with a specific orientation. But this will also mean a better quality for users as bad effects like Venturi will be anticipated, like the one for example at the bottom Arch of La Défense in Paris could have been managed before construction. This would have avoided thousands of euros of works to workaround this design error.

But the quality of future interior spaces will be affected by these new trends, allowing the decrease of disagreements linked to bad interior spaces ventilation, too cold air conditioning systems or propagation of bacterial diseases in healthcare spaces. Since early stages of design, it will be made possible to redesign and reposition Systems or spaces themselves for a better life quality.

 

BIM & IoT, a new trend to operate the assets

Optimizing the design and construction process is important to win all these climate related challenges and lower wastes of materials and bad designs, but the key to success will be in the operation and maintenance phase, which represents 80% of the total cost of the building. In that perspective, having a BIM Model to operate in a better way is the first step to success, but connecting it to the IoT will be even more important. This is why Companies like Autodesk have started to deeply invest in innovative and disruptive technologies like Autodesk Forge, allowing the development of ad-hoc technologies and platforms like Dasher, connecting BIM and IoT and allowing to control and monitor any sensor, captors, heating and cooling systems from a BIM Model, out of the fact that it completely blows out traditional heavy systems on the market.

Time is now!

The challenge is high, but beautiful and as you’ve just read it, Government are mandating everywhere, all the resources, innovative new processes and technologies are here, so whether you’re a designer, a builder, an Energy Engineer or Specialist, or an owner, you can beat the expectations and help heal our planet and make it a better place to live for our children and the future generations, and deliver some stunning buildings. So, it’s your turn to play the game!

Les changements climatiques dramatiques pour certains, que nous constatons quotidiennement dans le monde et qui sont les conséquences directes de notre planète réagissant aux maltraitances que l’homme lui a fait subir cours des siècles derniers en surconsommant, en détruisant et en malmenant ses ressources, démontrent un réel besoin et une vraie nécessité de prendre des décisions rapides et efficaces pour protéger notre environnement.

D'ici 2050, plus de 10 milliards de personnes partiront vivre dans les villes, créant ainsi une forte demande pour la création de villes intelligentes, de nouvelles infrastructures, de bâtiments, de systèmes de transport, de parcs et de services publics. Les spécialistes estiment le besoin à près de 1000 bâtiments devant être construits chaque jour pour répondre à cet afflux de population. Cela va également générer une accélération de l'empreinte carbone, une consommation massive des ressources naturelles de la planète, tout en prenant compte le fait que les bâtiments sont déjà responsables de plus de 50% de cette catastrophe environnementale annoncée.

L'humanité doit trouver des solutions rapides et viables pour surmonter ces défis et se remettre sur le bon chemin qui permettra de développer un environnement plus sûr, pur et empreint de bien-être pour nos futures générations.

Par conséquent, nous devons trouver de nouvelles façons de concevoir, construire, exploiter et entretenir notre environnement bâti qui nous permettront de créer de nouvelles générations de villes, de bâtiments et d'infrastructures à haute performance, capables de générer des énergies propres en utilisant le soleil, le vent, la mer et la terre afin d’échapper au piège des énergies fossiles.

La plupart des pays ont compris l'importance et l’enjeu de ce qui se passe ici-bas. Des décisions importantes ont depuis été prises grâce notamment à des conférences internationales telles que la COP 21 à Paris …

Sachant que le secteur de l'Architecture, de l’Ingénierie et de la Construction est l’un des moins avancé technologiquement comparé à ceux de l'automobile ou de l'aérospatiale et que le montant des investissements dans les technologies le positionne avant-dernier devant l'agriculture et la pêche, tout le monde comprendra facilement que le défi à relever est de taille.

Mais le changement a été initié maintenant depuis plus de 10 ans – commençant aux Etats-Unis après la grande crise de 2008 – et les obligations BIM dans de nombreuses régions du monde poussant à l'utilisation des processus BIM pour réduire l’empreinte carbone et la consommation énergétique des bâtiments de 20% joue en cette faveur. Les professionnels de l’AEC ont commencé leur mutation vers ce nouveau paradigme.

De nouveaux modes de production

La production, qu'elle soit intellectuelle ou physique, a fortement évolué, notamment dans les pays pionniers comme les États-Unis, la Grande-Bretagne, les pays nordiques ou en Asie.

Qu'il s'agisse de respecter et d’atteindre les objectifs des réglementations internationales ou locales pour des performances du bâtiment telles que les certifications LEED, BREEAM, HQE (Haute Qualité Environnementale) ou encore RT 2012 en France, il n'y a pas d'autre moyen que d'utiliser de nouveaux procédés et approches. Le BIM est certainement le plus célèbre processus que vous connaissiez.

BIM pour Building Information Modeling, une approche collaborative pour la conception, le partage, la construction et la gestion de nos actifs bâtis entre tous les acteurs d'un projet, et cela du propriétaire ou maitre d’ouvrage, aux architectes, ingénieurs, en passant par les entreprises de construction.

Le I du BIM prend tout son sens lorsque l’on parle de performances énergétiques car toutes les analyses, estimations, calculs de performances basés sur des critères utilisent ces données afin d’être réalisés.

Ces anticipations peuvent rapidement et dès les premières esquisses être effectuées à partir d'appareils mobiles, et peuvent partir de simples études d’ensoleillement sur une période et un lieu donné…

Jusqu'aux calculs de radiations solaires sur les façades de votre futur projet, permettant ainsi de comprendre quel matériau sera choisi pour une façade spécifique en fonction des contraintes de chaleur auxquelles il sera exposé …

Le Cloud, pour des calculs puissants sur la base de données météorologiques

Grâce à des technologies comme Insight 360, un moteur de calcul complet des performances énergétiques basé sur le cloud, vous serez capable de réaliser de nombreuses simulations de plusieurs variantes d'un même projet et obtenir ainsi des aperçus relativement précis de ses performances et comportements dans la vie réelle. En utilisant des modèles énergétiques tels que le DOE 2.0 (Department Of Energy 2.0) et en s’appuyant sur les données des stations climatiques et météo les plus proches, on permettra aux concepteurs de prendre les bonnes décisions, de comparer plusieurs hypothèses, et d'évaluer et d'avoir les bonnes conversations entre toutes les parties prenantes dès le début du projet.

Non seulement cela aidera à calculer les comportements futurs du bâtiment, mais cela permettra aussi d'évaluer les quantités de matériaux, et donc d'éviter les déchets inutiles et de choisir la meilleure option pour avoir un bâtiment plus durable et de meilleure qualité.

Ces approches sont à la fois utiles pour les nouvelles constructions, mais aussi pour la rénovation, où la technologie permettra de capturer rapidement et numériquement les conditions existantes d'un bâtiment, ce qu'on appelle aussi capture de la réalité, permettant ainsi de créer rapidement un modèle BIM d'un actif existant et d'évaluer sa conformité aux nouvelles réglementations.

Rapid Energy Modeling, rapide et efficace pour prendre les bonnes décisions

Les chercheurs et les spécialistes énergétiques d’Autodesk ont ​​développé ce qu'ils appellent REM ou Rapid Energy Modeling, en utilisant des nuages ​​de points (provenant de drones ou de scanners laser) ou de fichiers CAO pour l'approche la plus simple de remodélisation de bâtiments existants. REM comprend trois éléments clés qui capturent, modélisent et analysent. Un modèle BIM peut être recréé avec différents LOD (Niveau de détails), et une fois paramétré et géoréférencé, vous pouvez obtenir des résultats étonnants en un clin d'œil grâce aux solutions de calcul d'énergie basés sur Cloud et avoir des résultats qui s’approchent de 3 à 5% de la vraie consommation énergétique des actifs réels. Cela peut aider les propriétaires à prendre rapidement les bonnes décisions sur la façon de rénover leur patrimoine avec peu de moyens.

Cette approche a été testée par exemple avec succès il y a quelques années par le GSA (General Services Administration) aux USA, l’organisation en charge du patrimoine au niveau fédéral. Ces nouvelles approches arrivent désormais en Europe où la rénovation représente plus de 80% du marché en Europe du Sud notamment. Ceci est d’autant plus essentiel qu’il existe un grand nombre de monuments historiques, exigeant une approche de modélisation spécifique, délicate et prudente pour des raisons architecturales et patrimoniales évidentes.

Generative Design & Intelligence Artificielle, l'alliance parfaite !

En utilisant ces nouvelles approches, le temps est littéralement compressé et c'est la réponse idéale tant à l'avenir les défis seront grands, avec un besoin de construire plus de 1000 bâtiments par jour. Il devient d’autant plus important de trouver des processus d'accélération de la conception et de la construction plus efficaces. Autodesk a largement investi dans des domaines tels que la conception générative et aussi avec des technologies ouvertes comme Dynamo, allié à la puissance de l'intelligence artificielle, cela donne la possibilité de rechercher de nouvelles façons de concevoir des bâtiments écoénergétiques. La simulation d’apport de lumière naturelle dans un bureau peut prendre alors seulement quelques secondes, contrairement aux anciennes méthodes où des jours complets de calcul étaient nécessaires.

Génération d'énergie et anticipation des effets atmosphériques

Grâce aux simulations CFD et aux tunnels du vent, il sera possible d'évaluer la quantité d'énergie qu'un bâtiment pourra générer à un endroit spécifique ou avec une orientation particulière. Mais cela signifiera aussi une meilleure qualité pour les utilisateurs car des effets néfastes tels que le Venturi pourront être anticipés, à l’instar de l'Arche de la Défense à Paris où les turbulences sur la dalle auraient pu être anticipées avant la construction. Cela aurait évité des dizaine de milliers d'euros de travaux pour pallier à cette erreur de conception.

Et la qualité des futurs espaces intérieurs sera elle-aussi affectée positivement par ces nouvelles tendances, permettant la diminution des désaccords liés à la mauvaise ventilation des espaces intérieurs, aux systèmes de climatisation trop froids ou à la propagation les maladies bactériennes et nosocomiales dans les établissements de santé. Depuis les premières étapes de la conception, il sera possible de redéfinir et repositionner les systèmes de ventilation, chauffage ou refroidissement ou redéfinir les espaces eux-mêmes pour une meilleure qualité de vie.

BIM & IoT, une nouvelle tendance pour exploiter les actifs

Optimiser le processus de conception et de construction est important pour relever tous ces défis liés au climat et pour générer moins de déchets de matériaux et de mauvais projets, mais la clé du succès sera concentrée sur la phase d'exploitation et de maintenance, qui représente 80% du coût total du bâtiment. Dans cette perspective, avoir un modèle BIM pour fonctionner de manière optimale est la première étape vers un succès programmé, et connecter le BIM à l'IoT sera encore plus important. C'est pourquoi Autodesk a commencé à investir massivement dans des technologies innovantes et révolutionnaires comme Autodesk Forge, permettant le développement de technologies et de plateformes ad hoc de gestion énergétique d’un bâtiment comme Dasher 360, connectant BIM et IoT et permettant de contrôler et de surveiller les capteurs, senseurs, systèmes de chauffage et systèmes de refroidissement d'un modèle BIM, rendant ainsi totalement obsolètes les systèmes traditionnels lourds de GTB et GMAO actuellement sur le marché.

 

L’heure est venue !

Le défi est grand, mais noble comme vous le savez, les gouvernements ont de plus en plus d’obligation dont celle du BIM, mais toutes les ressources, tous les nouveaux processus innovants et toutes les technologies sont là pour aider à gagner ces défis. Que vous soyez un concepteur, un architecte, un constructeur, un ingénieur, un spécialiste en énergie, un propriétaire ou maître d’ouvrage, vous pouvez gagner la partie et aider à guérir notre planète pour en faire un monde meilleur pour nos enfants et les générations futures, et livrer de nombreux et magnifiques bâtiments.

Alors, c'est à vous de jouer !
