MECHANICAL

Mechanical Engineers and Designers can quickly create a preliminary physical model of the

buildings HVAC and plumbing systems using many of the HVAC and Plumbing placement tools

found on the HVAC and Plumbing Design task menu. The physical model is important not only

for coordination with the other discipline models, but it will also be used for the creation of the

Mechanical HVAC and Piping/Plumbing drawings, along with any necessary schedules and

reports.

This chapter will give an overview of basic Mechanical Building Designer concepts that need to

be understood to effectively create and modify designs.

MECHANICAL BUILIDNG DESIGNER FEATURES

Mechanical Building Designer supports a 3D workflow, with 2D output. Intelligent components

allow design engineers to work in the 3D model, while changes are automatically updated and

synchronized with the 2D drawings. Automatic drawing generation uses industry-standardrepresentations of mechanical system components. Automated connections, routing and sizing

tools, and system component editing all designed to increase efficiency and workflow.

Mechanical Building Designer is also integrated with all the AECOsim Building Designer

solutions to ensure that designs and documentation are coordinated throughout the design and

construction phases. Design project models provide extensive continued use during life cycle

operations and future projects. Compatible Building Designer tools such as Clash Detection,

provide integrated collaboration and analysis to facilitate coordination of designs with all

disciplines in the project team.

Significant Mechanical Building Designer features include:

Supports both HVAC and Plumbing disciplines-Placement, modification, and

manipulation tools are available to each discipline.

Drawing resymbolization control- Automated drawing representations for mechanical

components are customizable. Standard single line and double line presentations can be used

or they can be edited to meet company and project requirements.

Dynamic routing connections place transitions, fitt ings, and combinations of

fittings as route sizes change- Placement commands automatically place fittings, such as

elbows and transitions, and symbols in logical locations without leaving the command.

Automatic labeling and label updating - Various components are labeled with one

command. Labels are associative and update automatically when changes to components are

made.

Automatic device hookup - Devices and route elements are hooked up by selecting them.

Additional settings contain options for connecting devices to existing route elements. If

requirements exceed settings, then hookups are finished automatically.

AccuDraw key-in short cutsspecific to the Mechanical Building Designer

application- AccuDraw key-ins assist placement by re-orientating components dynamically

during placement or modification operations.

Context sensitive option menus assist with DataGroup property entries - A right

click on key components launches option menus and dialog boxes used to apply entries totentatively placed or modified Mechanical Building Designer elements.

Integrated schedules and reporting- Building information can be entered at any point

during the decision making and modeling process. This information is managed and used by

the DataGroup System to quickly generate accurate, user produced, schedules and reports.

Automatic manufacturer catalog selection - Automatic component selection from widely

recognized manufacturer catalogs simplifies the routing process. Manufacturer catalogs can be

queried during both the placement or modification operations.

System analysis tools- Analyze individual routes or runs as well as entire systems.

Functionality includes automatic detection of disconnected components, global assignment andcalculation of flow rates and velocities based on designed values, system optimization and

automatic generation of system ID's and insulation.

GBXML Export- The energy analysis model and GBXML export tool employ the Energy

Analysis Module (EAM). EAM is a web based application that enables design and modeling

applications supporting the GBXML (Green Building XML) schema the ability to use common

building energy analysis applications.

PARTS/FAMILIES AND DATAGROUP DATA

Mechanical Building Designer componentsare intelligent 3D models of ducts, pipes, diffusers,fans, fittings, valves, pumps, and in line devices. Mechanical Building Designer is delivered

with predefined parts and part families; however, new parts and part families can be defined to

suit any specific project type. Part/Families data includes the default symbology definitions for

these components used for both design and drawing environments.

The DataGroup System is a data schema utility common to all Building Designer applications.

Design teams from every discipline need a system that enables them to assign important

model data to model objects to distinguish their use. Many mechanical teams place duct and

fittings that have different usage requirements depending on environmental conditions and

other engineering variables. Assigned catalog item data must place with each item instance

and the system must also track and manage the data for schedules and reporting.

Furthermore, design teams need to be able to set catalog items and instance data for a host of

placement tools so that workflow can begin and continue without interruption.

SNAPS, ACCUSNAPS, AND ACCUDRAW

Snaps and Tentative Snaps are covered in theAECOsimBD-000-Introduction to AECOsim

Building Designer Core Functionality,but the mechanical tools also make use of

discipline specific connection points, to facilitate correctly connecting (or snapping) one

component to another.

Icon Locks (Ctrl+Shift+I)

Icon Locks determine whether data points and snap points will be projected onto the ACS

plane (locked mode) or remain at the true placementelevation (unlocked mode). Whenever aplacement tool is chosen in Mechanical Building Designer the locks will automatically be

unlocked, since placement is typically relative to other components and not an ACS plane.

THE INTERFACE

The Building Designer tasks dialog box, by default, docked

on the left side of the Building Designer application window,

provides all the Mechanical Building Designer tasks and

tools in task toolboxeswhich organizes them into logical

groups based on their specific type of use. For instance, the

HVAC Oval Ductstask contains all the Mechanical

Building Designer component placement and component

modification tools for placing oval ductwork. TheHVAC

Equipment task contains all the tools necessary for

placing mechanical equipment in the model.

Similarly, Mechanical Building Designers drawing and

reporting features are provided in several other tasks; the

Datatask, the Drawing Compositiontask and the

Annotationtask.

Mechanical Building Designer provides Mechanical

placement tools that simplify connect point sensitivity,

selection of components, and provide increased component

availability for more realistic system models.

Mechanical components obtain and maintain their

intelligence through to their categorization in the

Part/Familysystem. And within that categorization is

further definition, including size, material, orientation,

drafting attributes, labeling, and even specific customizable

notes such as manufacturers name. The DataGroup

Systemextends the intelligence of Mechanical members by

managing the Part/Familydata and additional

Datagroupdata used in processes throughout Mechanical

Building Designers features.

Enhanced placement functionality takes advantage of

manufacturer catalogs.When available, manufacturer

catalog entries are scanned for the nearest match to user

inputted data. DataGroup property values for key

dimensional parameters such as diameter, radius and angle

are examples of the scanned properties. Data is

automatically applied from the manufacturer catalog to the

DataGroup Instance Data dialog box during placement.

PLACE EQUIPMENT

The Place Rectangular AHUtool, found

on the HVAC Equipment task bar, is used to place

an AHU in the model. AHUs are available in twocategories based on their shape type; rectangular

or round. Multi-end AHUs are also available up to

5 ends.

The Place Componentdialog along with the

DataGroup Instance Datadialog opens.

The AHU end conditions are modified in the End

Spec schema properties. Set the Widthand

Depthof Duct Connections.

Set the overall length of the AHU with the Total

Lengthproperty.

CellSymbol Sets model cell from cell library to

the AHU by fitting cell proportionally to extents of

device.

EndType The end conditions of ducts are set to

flange, male or female connections with full

dimensional control by setting the EndType

property. Also, the two ends are independent, and

may have different connections. For example, thevalue fl-2; fe-.13 creates a flange at End1 with

size 2, and a female connection at End2 with a

clearance of .13.

Enter a data point to place the member in the

model.

Besides these default devices, Mechanical Building

Designer allows designers toassemble a unit by

selecting components of the AHU like duct, filters,

fans, dampers and air modifiers.

PLACE DUCTWORK

The Place Rectangular Ducttool, found

on the HVAC Rectangular Ducts task bar, is used

to place rectangular ductwork in the model. Ductis a component type with unique properties and

behaviors. Placing duct employsautomatic

fitting placementlogic that senses the

dimensional properties of the duct and orientation

in 3D space of the AccuDraw Compass to correctly

select combinations of elbows, transitions,

takeoffs and coupling components to maintain

connectivity throughout the route.

The Place Componentdialog along with the

DataGroup Instance Datadialog opens.

In the Place Componenttool, set the

justification to the center-centerposition.

Set the active Family and Part in this example to,

Duct/Supply-New.

Turn on the Orientation, Size andShapein the

Place Componenttool settings. The duct

appears attached to the pointer.

PLACE DIFFUSER

The Place Top Square Ceiling Diffuser

tool, found on the HVAC Grilles & Diffusers task

bar, is used to place grilles and diffusers in themodel.

Once selected, the Place Componentdialog

along with the DataGroup Instance Data

dialog opens.

If placing the diffuser in a ceiling grid, set the

justification to the top-leftposition in the Place

Componentdialog.

Set the active Family and Part, for instance,

Diffuser/Supply-New.

Set the parameters for the diffuser under the

CustomParamDiffusertab. Alternatively,

select a catalog name in the Catalog Namefield

under the Propertiestab. Once the catalog is

defined, right click in any of the

CustomParamDiffuserfields and select

Manufacturer Catalog.

In the Manufacturers Catalog dialog, set any

required parameters like the diameter of the

connection (D1) to filter the catalog down to

available items that fit the criteria. Select the item
