These attributes form a core value of the building information modeling (BIM) process, for which Autodesk � Revit Architecture software is purpose-built to support. Using a speculative urban high-rise project as the model for exploration, this white paper details how CASE Design, a design technology consultancy based in New York City, utilized the new conceptual design tools in Revit Architecture to more easily create massing designs; explore design alternatives based on qualitative and quantitative feedback; and address various environmental, constructability, and aesthetic concerns that arose during project realization. 1. Parametric Massing Design: The Challenge of the Building Form While approach and attitude about design may differ from firm to firm, most designers would agree that iterative design can lead to more optimal solutions. However, several concerns arise, such as: How does a designer find the right solution for any given project? How can design criteria be used more effectively to evaluate possible design solutions? And finally, how can technology help make this exploration and discovery process more informative and more efficient? With regard to the specific project explored in this white paper, several key constraints affected the outcome of the design. 1.1 Site and Context Requirements The site for the tower is located on the edge of a high-rise business district, adjacent to a low-rise residential district near a waterfront. The site is an undeveloped triangular parcel bordered by two major streets. An existing secondary street to the north of the site will be closed and incorporated into the buildable footprint of the parcel. 1.2 Programmatic and Planning Requirements The program of the tower will be a mixture of hotel (7,000 square meters) and residential (19,000 square meters) space, with the hotel occupying the lower section of the building. The unusual shape and context of the site present challenging planning requirements. The design must meet the stated programmatic requirements within a tight footprint of 951 square meters, while not exceeding 150 meters in height. Furthermore, the design should minimize the impact of overshadowing on the adjacent buildings and streets. 1.3 Environmental Requirements Complicating things further is a requirement calling for a building form that is designed for solar collection. With this added requirement for energy reduction, the exterior shell of the form will utilize special photovoltaic panels to make best use of the solar energy available to the site, which will translate to lower operating costs. spring_2009 www.AUGIaecedge.com 11 department contributed white paper | contributed wHite PaPer | CONCEPTUAL DESIGN MODELING IN AUTODESK REVIT ARCHITECTURE 2010 2. Massing Approach: Creating the Building Form The new Conceptual Mass environment supports both surface and solid modeling workflows. The solid modeling workflow maintains the benefits of working with mass families, such as the use of the Building Maker tools, while also providing new direct manipulation tools that significantly enhance the ability to create faster, iterative design models. With these new tools, surfaces can now be created and manipulated, or they can be thickened to create solid masses. Both surfaces and the solid faces also now serve as the basis for the new custom panel families. This white paper focuses primarily on the solid modeling workflow--the most appropriate technique for a volumetric design--and demonstrates how these masses can be incorporated into a Revit Architecture project. 2.1 Maximizing Buildable Volume To visualize the extents of the maximum buildable volume, the full parcel is extruded to the maximum height (150 meters) using the Create Form button, a new context aware geometry creation feature that replaces individual modeling commands such as Extrusion, Sweep, and Blend. This conceptual mass family is placed into a Revit Architecture project containing the site and surrounding context. Levels are then used to create mass floors from the maximum buildable volume, and a mass floor schedule is generated showing a total buildable area of 35,205 square meters. Conceptual Mass in the Project Environment Mass Floor Schedule Although these results might be ideal for the developer, they leave much to be desired from both urban and aesthetic perspectives. In addition, city planning officials would likely have concerns. However, by utilizing the new conceptual mass tools in Revit Architecture, these issues can be more readily addressed. 2.2 Responding Intuitively to Urban Context For the tower to respond to its urban context, the programmatic volume requires fundamental modifications to create better public space at the street level. To address this, the north face of the conceptual mass is split using the Add Profile and Add Edge tools, allowing for a more generous pedestrian walkway and providing better light and air to the adjacent building to the north. 1 www.autodeskcatalog.com/AECEdge spring_2009 2 | contributed wHite PaPer | department contributed white paper CONCEPTUAL DESIGN MODELING IN AUTODESK REVIT ARCHITECTURE 2010 Performing this action allows the design team to manipulate the conceptual mass in a variety of ways. In this situation, the lower section of the mass is moved away from the adjacent building. As a result of moving the east face of the conceptual mass, an entrance plaza and public space adjacent to the low-rise residential district can be created. With the quick edits in place, potential city planning concerns have been addressed. 2.3 Increasing Project Precision In order to understand the impact that design modifications have on the programmatic requirements, the conceptual mass is updated in the Revit Architecture project. Accordingly, the mass floors and corresponding area schedule in Revit Architecture are both automatically updated to reflect changes. With modifications in place, the current conceptual mass is now 1,990 square meters over the program target. Up until this point, design modifications have been made graphically via direct manipulation techniques. In order to better control the precision of future modifications, reference planes and parameters are now added, enabling increased degrees of control through numeric input. With the introduction of bidirectional parameters, the model is modified using both numerical and graphical means. Changes made using the direct manipulation tools will now conversely update the numerical parameters in the model. The introduction of parameters also provides the flexibility to make changes directly from within the project environment, giving the design team instant feedback from area schedules. The tower design now satisfies the requirements of both the client and city planners; however, additional steps should still be taken to further refine the building form and environmental impact. 2.4 Minimizing the Impact of Shadows Reducing the overshadowing of the tower on neighboring buildings and streets becomes the primary concern at this stage of the design process. By enabling the interactive shadow tools within Revit Architecture, the design team can quickly identify troublesome areas. To address these areas, the west face of the conceptual mass is altered to reduce the impact of shadows on the existing towers to the west of the site. With this simple action, the project team reduces the effects of overshadowing, sculpts the top of the tower, and verifies that modifications meet program targets. spring_2009 www.AUGIaecedge.com 3 13 department contributed white paper | contributed wHite PaPer | CONCEPTUAL DESIGN MODELING IN AUTODESK REVIT ARCHITECTURE 2010 2.5 Maximizing Solar Collection With the building form beginning to take shape according to programmatic and site requirements, consideration is now given to designing for solar collection. Autodesk EcotectTM Analysis 2010 software, an interactive early stage building performance simulation tool, is used for solar insolation analysis. After importing the building form into Ecotect Analysis, tests reveal that the buildings to the west cast shadows across the western face of the tower, while the southern face, particularly near the top, is largely unobstructed. Based on the information provided by Ecotect Analysis, the southern face is further refined in Revit Architecture. Using the Add Edge tool, an edge is added to the south face, creating a top vertex that is then modified via direct manipulation. The result is a decreased angle of incidence to the sun. � Performing a second insolation analysis of the updated building form with Ecotect Analysis reveals an increase in solar radiation, indicating that the surface is now positioned to maximize photovoltaic panel solar collection. 2.6 Exploring Design Alternatives Using the completed mass as an underlay, additional design options are more readily explored. For this purpose, a series of profiles are created using "associative" 3D snapping, constraining sketches to the base mass, while a curvilinear tower is lofted through these profiles. The design is then modified by changing parameters, with revisions automatically reflected in both mass options. With the mass family updated and loaded into the Revit Architecture project, switching between mass types can be performed more quickly and seen together within the updated area schedule. Parameter-Driven Design Options Curvilinear Tower Option The second curvilinear mass adds additional floor area, but also reduces the overall height of the building form. The result is a new building form that still meets area targets, but also slightly reduces the shadows it creates on neighboring buildings. 3. Custom Panelization: Creating the Custom Panel In addition to the new Conceptual Mass environment, Revit Architecture now provides an environment for the creation of custom panel families and tools to automate their population onto the surfaces of mass forms. The result is a simplification of a once complex technique, now making it more readily accessible to all building designers. When creating Panel Design there are three key requirements for the design of custom panels. 4 1 www.autodeskcatalog.com/AECEdge spring_2009 | contributed wHite PaPer | department contributed white paper CONCEPTUAL DESIGN MODELING IN AUTODESK REVIT ARCHITECTURE 2010 Solar Shading The envelope panelization should vary in density and depth based on orientation and adjacent buildings, providing solar shading that will minimize heat gain due to direct solar radiation. Cost and Constructability The designer should use precise material takeoffs and surface area calculations to assist in determining the feasibility of different panelization designs. Additionally, with respect to the construction process, a decision should be made as to whether off-site or on-site fabrication is the more cost-effective and appropriate solution. Aesthetics The panel pattern should be iteratively studied and aesthetically related to the geometry of the mass, ultimately contributing to the iconic qualities of the tower design. 3.1 Defining the Pattern In order to quickly test different paneling options, the Divide Surface tool is used on the faces of conceptual masses. Initially, the isocurves (UV) of the surfaces are displayed based on either the number or spacing specified in the options bar. These curves and their intersections form the basis of various predefined patterning options selected from the Change Element Type drop-down list. Visibility of these patterns is toggled using the Pattern Visibility button. Spacing, rotation, and justification of the pattern are easily controlled by directly interacting with the model and receiving instant visual feedback. Divided Surface Hex Surface Pattern Arrow Surface Pattern These patterns become the basis of user-defined panels created in the new custom panel family environment. After evaluating several options on each mass, the rhomboid and hexagonal patterns are selected for their respective aesthetic associations with the faceted and curvilinear masses respectively. 4. Designing the Panel: Panel-Based Solar Shading The patterns are now used to understand the potential effects of orientation and solar radiation on the panels. By exporting this model to Ecotect Analysis and running a solar insolation analysis, the project team is able to determine which faces are receiving the most direct solar radiation and the resulting amount of shading required. 5 spring_2009 www.AUGIaecedge.com 1 department contributed white paper | contributed wHite PaPer | CONCEPTUAL DESIGN MODELING IN AUTODESK REVIT ARCHITECTURE 2010 The information resulting from this analysis will become useful in determining the panelization approach and the panel configuration on each mass by informing the shape of the frame and density of the panels. 4.1 Customizing the Panels Within the new custom panel family environment, a rhomboid pattern is used as the basis for a new panel family. The width and depth of the frame are controlled using interactive dimensional parameters. In order to vary the density of the panels, the project team mimics a process of recursion, where the first panel is divided into four, and then subsequently each of these panels are further subdivided into four additional panels. Using visibility parameters, different types are created within the panel family. This allows the project team to vary the density of the panel based on solar shading and collection, as well as constructability and aesthetic considerations. Finally, the faces of the frame are painted, which allows material takeoffs to be extracted from the project once panels are applied. Another custom panel family is created for the curvilinear mass using the Hexagon pattern. Rather than controlling the frame width by changing a dimensional parameter, a graphical control rig is created by using offset reference planes that drive a named parameter. Like the rhomboid panel, materials are painted on the frame, making it possible to schedule surface area after the panels have been populated. 4.3 Populating the Panels onto the Building Form With two panel families created and loaded into the conceptual mass model, new panel types are chosen from the Change Element Type drop-down list, making it possible to apply panels to each face of the mass. Individual modifications are then made to the panels based on existing solar performance and aesthetic requirements. This is done by selecting the appropriate panels and switching between the different types that were created within the panel family. In accordance with the panel requirements, denser panels are used in areas of greater solar exposure. 4.4 Using Quantitative Data to Inform Final Design Decisions Now that the panelization approach for each mass has been determined, scheduling tools are used from within the Revit Architecture project to quickly calculate the number of panels and the surface area of each material used. 1 www.autodeskcatalog.com/AECEdge spring_2009 6 | contributed wHite PaPer | department contributed white paper CONCEPTUAL DESIGN MODELING IN AUTODESK REVIT ARCHITECTURE 2010 Since the underlying masses are controlled parametrically, the project team can continue to update and refine the design based on this information, incorporating real-time feedback and modifications, until it is finally concluded that the preliminary design with the custom rhomboid panel patterning is the most optimal design solution for project requirements. Conclusion This white paper and speculative project have demonstrated some of the potential uses of the new conceptual design tools available in Autodesk Revit Architecture 2010 software. The enhanced intuitive design environment helps give designers a notable advantage through the pairing of robust parametric modeling tools for earlier concept development with an already comprehensive and mature BIM platform. The result is a natural extension of the Revit Architecture design environment into a highly capable conceptual design solution for sophisticated form exploration, custom patterning, and panelization.

At Current Builders and 30 www.autodeskcatalog.com/AECEdge spring_2009 feature focus Revit Cross-Discipline other industry organizations, it is becoming established that Building Information Modeling (BIM) refers to a set of tools (i.e. the technology, toolset, or `means') and Virtual Design and Construction (VDC) encompasses the processes, goals and concepts (i.e. `methods') of applying BIM as well as other technologies.VDCinvolvesthe communication and collaborationbetweenprojectparticipants usingtoolsetsasdiverseasBIM and product lifecycle management (PLM) systems as well as estimating and scheduling systems. model.Regardlessofthenumberofteammembersexchanging nativeBIMmodels,awell-managedVDCenvironmentshould be able to leverage relevant information into BIM.

I have observed that Contractors and leaders in related fields are less interested in the technical`means'ofBIM,than in the processes and `methods' of VDC.

Local Chapters are the physical side of the organization. Many members carry on real friendships and relationships via the website but they may never actual meet each other face to face or shake one another's hands. Our Local Chapters on the other hand are real, face to face and every bit as important to the organization as a web site. In contrast many of the members of a Local Chapter may rarely interact with each other on the web. The ideal situation, we believe, is when our members find a balance between our real and virtual presence as a resource. Some members don't have an option to attend a Local Chapter meeting because one doesn't exist near them. This is an opportunity to start one and the AUGI web site is the place to find some resources and to ask for help! We hope you can connect with a Local Chapter and if not maybe you are the right person to start one!

FAvoRite MeMoRies While preparing this article I happened to speak with Chuck Keeleyandhesharedacoupleofhisfondmemorieswithme. "For me one of the most memorable things Jim ever did at one meeting was when a newbie asked how easy it was to learn Revit and Jim asked him, "Have you ever seen Revit or used it before?" He answered no. Jim asked him to "take the wheel" and sit behind the laptop. He asked him to draw a wall without offering any help. He did it. Then Jim asked him to put a door in the wall. He figured it out." Andonemore. "I met an architect named Donald Sutherland when he walked into a SCRUG meeting for the first time at WATG. I asked him if he was a Revit user. He said he just bought it a few months earlier. I asked him how it was going so far and he said he had finished 6 small projects and finished construction documents already. (Donald informed us since that these six projects consisted of a 24,000 SF commercial building, a 4,000 SF medical tenant improvement and four (4) 2,500 SF cottage type houses including some custom families) I was shocked. He said the projects were small projects, but I was still taken back by how fast someone could use Revit productively. I then asked him where he was trained. He said he trained himself with the tutorials and with the AUGI support groups. That just proved to me that Revit was intuitive and that smart dedicated people could learn it on their own."

The critical philosophical point was our vision of Revit as one piece of a larger practice change, from a 2D document-based workflow,toaninformation-modelbasedworkflow.Revitwould be one of a set of tools we will use together, to drive building design. Thefirstandmostcriticaldecisionwasastrategicone:Implement BIM broadly across the whole organization. Notonly didwewanttoseeallofficesadoptthetechnology,wewanted everyone to move at the same rate, and to work together as much as possible. When it came time to plan how we would achieve these ends,welookedatanumber of approaches, but a fewimportantpointsbear mention. A major decision was to focus on education and training, which we described as "training our way out of this mess." Burt Hill historicallyprovidedinternaltraining,forexampleon 2DMicrostation,anditbecameapparenttousthat ourownBurtHillexpertscouldprovidebetter relevant training and coaching than external trainers we were familiar with. External trainersknew(butnotalways)whichbuttons to push, but too often missed the critical impacts that changing software andworkflowshaveonpractice. Another choice made after that meeting was that the effort to implement BIM shouldbedoneasa"project"withaseparate budget and manager, not simply an "IT" effort. This was important as the majority of stARtinG out sMAll (in A BiG FiRM) InDecemberof2003,myfirm'sinvolvementwithRevitbegan with a single project team of four people who decided to try thisup-and-comingpieceofsoftwareonahigh-riseresidential project.AtthetimeBurtHillhadabout350staffmembersin sixregionaloffices.Today,BurtHillnowaninternationalArchitecture, Engineering, Planning and Design firm has 1,000 peoplein12officesspreadaroundtheglobe.Duringthistime of extraordinary growth, a team of dedicated individuals have worked together to implement Revit architectureasourtoolofchoicefor ArchitectureandInteriordesignand documentation.Now,fiveyearslater we'veusedRevitforoveronehundred projectsandamajorityofourArchitecture and Interiors staff have been trainedtouseRevit.

Room elements are important and useful in Revit Architecture; their equivalents in Revit MEP--Spaces--are fundamental. Spaces in MEP holdenergyusageinformation such as lighting and ventilation requirements and heat loss calculations. MEP puts the required fieldsintothepropertiesof pre-existingornewspaces, andtheuserpopulatesthe valuesduringMEPoperations. MEP places spaces automatically where rooms exist. Revit Architecture can read thesefields,butdoesnotcreatethembyanycurrentlyavailable tool, although you can always create custom parameters.

Its mission is to involve you, the customer, in the progress of design technology solutions. We're not a beta program (although Autodesk does have an active beta community), or a usability team, because the technology we work with is too new to be a product. The user feedback that you provide to Labs is really on product ideas, while they're still in an early conceptual stage. The best way to learn about Autodesk Labs is to start experimenting yourself."

"It is a proof of concept tool that is intended to be used with the Revit 2010 products.

Quoted from the Lab's overview:"The RDBLink tool allows the user to export data from the elements in a Revit project and maintain relationships against data that exists outside of Revit. The tool allows for both import and export of the project data and will allow the user to make changes on the database side that affect the data within the project once imported. Also, during subsequent exports of the data to the same database, only data from the project will be affected, so any new fields or tables added to the database for your own purposes will remain intact along-side the newly exported data. The RDBLink import tool provides a grid view of the data to allow the user to make any final edits before import. This grid control also allows the user to create Revit Shared Parameters which will add new fields for those parameters to the database in the related tables. Changes to these new fields within the database will update these Revit Shared Parameters upon future imports."

Duetothelearningcurvetheengineersweregoingthroughwiththeir firstproject,itwastakingthemlonger to produce drawings. However, Revit MEP ended up saving the team time and money as drawing duplicationwaseliminatedandinterference and conflicts became visible. For example we had an instance where our HVAC team could not get all of their equipment into the basement area. This was easily visible when they started to layout all of their ductwork and ran someinterferencechecking. Withthewaythestructure was designed at first, there just wasn't enoughroom.Asaresult of this discovery, our structure team made some changes, and just two feet was addedtothebasement area.
