MEP spaces
Revit MEP 2009 includes the ability to create spaces that are independent of rooms. Areas that are to small to be classified as a space are accounted for automatically. This capability provides increased control over how the geometry of the area is defined in the analysis results. The result is a more accurate analysis model.
Spaces inherit the architectural room information initially created in the architectural model. Those spaces can be associated to zones. The spaces automatically update as the room boundary updates in the architectural model, whether the model is in the host file or linked.
Easily assign information, such as occupancy or latent and sensible heat gain, to a single or multiple spaces.
HVAC zone element
New to Revit MEP 2009 are HVAC zones. This powerful feature enables engineers to dissect architectural rooms into identifiable spaces and groups of spaces, based on engineering volumes, required as part of systems equipment selection as well as to perform accurate heating and cooling loads calculations.
Zones also appear in the system browser to provide more flexibility to identify which systems are in which zones. In addition, zones can be color filled for easy visual reference.
Now you can represent building spaces based on engineering needs.
Zone and light fixture data
Revit MEP 2009 provides the ability to export not only newly created HVAC zone data, but also lighting fixture element data for use in the IES
Heating and cooling loads
Heating and cooling loads reports have also been enhanced to reflect the powerful HVAC zones and spaces functionality new to Revit MEP 2009. Loads reports have been reformatted to logically display crucial design calculation results, including check sum values for identified zones or spaces. Viewing and navigating the Heating & Cooling Load dialog box and reports have also been enhanced. The Loads dialog box can be expanded for better analytical model scrutiny and includes new report navigation buttons to help you quickly locate desired report information.
You can also expand the dialog box to full screen and modify multiple spaces or zones at the same time. The heating and cooling loads report summary includes new engineering-specific parameter controls that provide more robust calculation results, as well as greater control over zone and space selection, and phasing.
Improved gbXML (green building extensible markup language) workflow integration helps maximize information going to third-party analysis programs with the benefit of the new spaces and zones.
Plumbing calculations
Revit MEP 2009 includes enhanced plumbing flow calculations to more accurately reflect plumbing standard flow calculations and conversions from fixture units to flow values in GPM. You can also view the fixture units in the System Inspector.
The total fixture unit parameter can be scheduled. In addition, the flow is a demand value, based on fixture unit count. The conversion between fixture units and actual GPM flow is based on universal plumbing code standards so you can estimate demand based directly on fixture unit.
Piping enhancements
Model sloped piping for all plumbing systems according to industry code. Simply define the rise over run while laying out your plumbing design, and let Revit MEP 2009 do all the calculations. With enhanced slope propagation, applying a slope to a run of multiple pipe selections, through fittings, is a breeze.
Revit MEP 2009 also offers improved routing features to help speed up your system design and layout, by providing improved proposed routing solutions to better match design considerations.
3D family content
Content, content, content! Revit MEP 2009 substantially increases MEP-specific content, and we are not stopping there! With this release, architectural and MEP content overlaps to streamline the architectural and engineering workflow, by providing MEP-specific content to architects for use in space planning.
Significant enhancements have also been made to content part type and behavior, helping to ensure that custom content creation maintains Revit MEP systems design integrity.
In addition, Autodesk Labs allows engineers to search and find generic or manufacturer-specific building products or components and associated design content. This content could include 3D models, 2D drawings, specifications, and descriptions for that product or component.
Modeling in section and elevations
Revit MEP 2009 includes enhanced design tools, and the ability to model in section and elevations improves design and layout functionality. Reduce time and number of steps required to create complex routing layouts by modeling in 3D, plan, and now section and elevations as well.
Design layout tools
Ease of use is key to laying out systems. Revit MEP provides the Layout Path tool especially for that purpose. In this release, users have greater control for more comprehensive layouts. Easily modify proposed layout solutions using the Layout Path tool by simply dragging main and branch sketch lines to better customize your layout. And of course, if you change your mind while still in the Layout Path tool, simply undo to reconfigure your design layout path sketch.
A streamlined user interface is a hallmark of the Revit® platform. Revit MEP improves on this by including option tool buttons for auto connect, justification, and tag on placement.
Size list integration
With the goal of providing tools to create virtual building systems and components, sizing table integration increases capacity to control system settings to reflect real-world MEP systems requirements. Quickly define the behavior of MEP systems components for more robust design and calculation results.
Select sizes from a list, or create custom sizing directly in the Settings dialog box. Comprehensive pipe sizing and fluid-based control parameters in Revit MEP software are based on materials, roughness, connections, and schedule/type.
Electrical wire sizes can be configured with correction factors as well as ground conductors.
The ton unit has been added in Revit MEP 2009 to provide check sums based on units that engineers use to calculate, size, and select mechanical equipment.
Transfer project settings
Increased coordination is central to Revit MEP 2009 enhancements. Now, easily transfer significant MEP project settings from one project to another. Quickly update project settings with revised project information, such as customized settings developed in integrated size lists.
Panel schedules and tick marks
Users have asked for greater control over the appearance of electrical schedules, and Revit® MEP 2009 answers that request. Now, format your electrical panel schedules just like other Revit® schedules, and improve sheet placement and information documentation by placing numerous panel schedules on a single sheet.
In the same way that size lists have been integrated, wire tick marks have also been integrated as standard families, helping to ensure greater usability and scalability. You can now edit them in family editor.
MEP detail lines
Revit MEP now has MEP detail lines that enhance construction documentation. Detail lines appear as solid lines for MEP graphical representation when you add detail to documents.
Draw detail lines in any MEP discipline view and help ensure that the MEP components stand out against the screened architectural background.
Mechanical display and layout
Size ductwork with improved duct justification integrity, helping to ensure communication of design intent. When using an eccentric reducer, be assured that the justification remains the same even after resizing.
Revit MEP 2009 works the way engineers think. Duct sizes appear natively in plan and section as they should appear based on industry documentation standards. In plan view, see width and then height; in section view, see height and then width.
Graphical and view control
Revit MEP 2009 now gives you greater display and graphical control with the powerful new ViewCube™ and SteeringWheels™ features that help you to navigate and view your BIM model with ease.
ViewCube and SteeringWheels are multiplatform viewing tools. Use these intuitive view navigation tools to quickly manipulate views to maximize efficiency. Also take advantage of the same rendering engine provided in Autodesk® 3ds Max® and Autodesk® VIZ software for high-quality 3D rendering with the mental ray® application.
View display performance
Revit MEP 2009 improves performance of hidden line regeneration, resulting in better working view performance.
Revit MEP helps to improve efficiency by sending users a more detailed error message to facilitate better design decisions.
