Air Handling Units


3 MODELS

3.1 Model workflow

One of the principle aims of BIM-MEPAUS is to enable efficient BIM workflows that see the design model

progressively refined through the design, virtual build and construction process to ultimately deliver a completed

Commissioned As-Built Model.

A key step in this process is the virtual build during which the change-out of the generic design components with

Manufacturer’s Certified Models (MCMs) occurs. These MCMs are able to support a range of construction and

commissioning workflows as well as the asset’s life cycle management post-handover.

The completed construction model generated through the virtual build is then used to drive a range of activities

including site layout, procurement and installation scheduling and tracking.

Once the installation is completed and the systems commissioned, as-built data and project completion information

are used to finalise the Commissioned-As Built Model for handover to the client.

3.2 Generic design content

BIM-MEPAUS generic design families provide a catalogue of sizes (types) or one adjustable parametric object, that

allow designers to spatially model to LOD 300 as well as specify the Air Handling Unit’s performance and quality

requirements.

The generic design model shared parameters have been developed through industry consultation and are

considered those necessary to schedule the quality and performance requirements for tendering and procurement

purposes.

Design firms with content libraries can pre-populate these Air Handling Unit design families with their specific quality

specifications in order to minimise repetitive data entry on each use in a project. This approach limits subsequent

scheduling to only those instance based performance parameters that are typically scheduled in specification

equipment schedules.

The generic design Air Handling Unit is setup to be fully adjustable, no specific catalogue of sizes is provided due

to the extensive variability of selections available.

3.3 Manufacturer certified content

The virtual build develops the design model into the LOD 400 construction model and typically involves changing

out the design content with manufacturer certified content. Where the manufacturer’s model is BIM-MEPAUS

compliant this should be readily achieved.

Manufacturer’s models are preferably generated from the BIM-MEPAUS Industry Foundation Models (IFM) and

are a single type family that has the Air Handling Unit geometry needed for the virtual build plus the manufacturer

data for the specific Air Handling Unit to be supplied to the project.

BIM-MEPAUS certified manufacturer models are fully interchangeable with the generic design models and provide:

Accurate geometry

Performance data

Full BIM-MEPAUS Revit operability.

Where the data is not able to be provided by the manufacturer in Revit shared parameter format, manufacturer data

should be delivered in Excel format using the BIM-MEPAUS Product Data Templates to allow the data to be efficiently

imported by the specialist trade contractor into their scheduling database or Revit virtual build model.

Microsoft Excel based product data templates are provided for this purpose on the BIM-MEPAUS website under the

specification product templates section. Where required additional fields can be drawn from the shared parameter

schedules in this specification to provide additional product data as required.


Air Handling Units


As the MCM and supporting shared parameter schedule replaces the certified drawings and technical schedules

that have traditionally been provided by manufacturers, the model accuracy should be no less than that provided

by a manufacturer’s certified drawing.

Manufacturer’s certified models should preferably include a link to a pdf or web page providing pre-commissioning

checklists for modellers and shop drawers to facilitate the proper incorporation of the component into the model as

well as providing the pre-commissioning check sheet for the project site team.

3.4 Commissioned As-Built Model

The commissioned as-built model comprises the construction model updated to reflect any changes made during

the field installation.


Air Handling Units


4 SHARED PARAMETER SCHEDULING

The shared parameter schema has been developed to effectively support data requirements for design,

procurement and commissioning as well as life cycle asset management.

All BIM-MEPAUS plant and equipment models have the same schedule structure shown below.

Identity

BIM Classification

System Analysis

Green Building Properties

Performance / Quality

Manufacturer

Commissioning

Completion

System Analysis, Green Building Properties and Commissioning schedules are only included where applicable or

where they have been defined by a relevant standard.

The schedules are progressively completed as the MEP services model progresses through design and virtual

construction to a fully completed Commissioned As-built component within the final model.

Schedule Section Generic Design / MCM

Model schedule

Schedule completion by

Identity Generic design model Designer / Manufacturer / Installer

BIM Classification Generic design model Designer

System Analysis Generic design model Designer

Green Building Properties Generic design model / MCM model Designer / Installer / Manufacturer

Performance /Quality Generic design model / MCM model Designer / Installer

Manufacturer MCM model Manufacturer

Commissioning MCM model Installer

Completion Schedule MCM model Installer

The identity and completion schedules must be completed for all components and once the values are defined are

fixed for the life of the component.

It is expected that not all data will be carried in the Revit design or virtual construction model with non-core data

likely to be managed off model using scheduling databases and/or spreadsheets. This non-core data is commonly

required for the finalization of procurement, commissioning and facility management purposes.

Manufacturer BIM data must be supplied in a format that can be imported into a data management system and/or

Revit based Virtual Construction model with suitable formats including:

MCM model incorporating BIM-MEPAUS Product Data Template shared parameters

MCM geometry model with supporting BIM-MEPAUS Product Data Template Excel file.

To allow efficient and reliable data exchanges, it is critical that the BIM-MEPAUS shared parameter names and

respective GUIDs be used.

Parameters indicated in bold font are core Revit model data expected to reside in the model whilst those in italics

are non-core data that can be managed either in the Revit MEP model or off model in a scheduling database.


Air Handling Units


Parameters notated with the symbol have an industry defined set of allowable values or descriptions that are

listed in the master BIM-MEPAUS shared parameter schedule.

It is noted that BIM-MEPAUS compliant manufacturer’s certified models can be used for the basis of design where deemed appropriate by the designer and/or where specific manufacturer plant and equipment is to be nominated.


Air Handling Units


5 AIR HANDLING UNIT SPECIFICATION

The following guidance has been developed through the industry consultation process as particular areas requiring

focus during the completion of the Air Handling Unit quality/performance schedules.

5.1 Air Handling Unit duty selection

Air Handling Unit duty should make appropriate allowances for system leakage and/or system diversity to avoid

issues with motor sizing, Air Handling Unit fan efficiency and system commissioning. The duct leakage calculations

should be based on ASHRAE or SMACNA ductwork surface area based methods.

5.2 Air Handling Unit installation arrangements

Air Handling Unit Installation arrangements are important in the Air Handling Unit selection process, the schedule

should nominate the required Air Handling Unit fan arrangement, coil handing and casing openings.

Air Handling Unit fan arrangements are coded as below, with this parameter selectable in the shared parameters

list of the generic design family.

Handings are always nominated left or right looking in the direction of the airflow.

Casing openings and coil connections are nominated in the shared parameters of the generic design family in

accordance with the surface nomination diagram and Air Handling Unit diagram below.


Air Handling Units



Air Handling Units


5.3 Smoke spill applications

Air Handling Unit’s contain several components that are covered under AS 1688.1, designers should familiarize

themselves with these requirements and ensure their design complies with the requirements. Plenums and casings

particularly relating to the construction of Air Handling Unit’s, shall be constructed to comply with the requirements

of AS 1668.1. AS 1668 1998 Part 1 requires

The exposed face of any insulation in equipment plenums, built-up air-handling and proprietary air-handling

plant casings shall have indices not greater than the following as determined in accordance with AS/NZS

1530.3:

a. A spread of flame index 0.

b. A smoke-developed index 3.

Masonry, concrete, metal or metal-faced sandwich construction shall be deemed-to-comply materials for the

purpose of this requirement. Where casings are of metal-faced sandwich construction, all raw edges shall

be covered effectively to ensure that the insulation core is not exposed, inside or outside the casing. Where

necessary, raw edges shall be fitted with edge strips. When located on the airstream side of the casing,

edge strips or gaskets between panels shall comply with the early fire hazard indices nominated above for

exposed insulation.

Where not exposed to the airstream, but otherwise exposed within the building, materials used for edge

strips or gaskets between panels shall have fire hazard properties in accordance with the requirements of

the relevant building regulations.

All gaskets thicker than 3mm between metal faces and all non-metallic edge strips that project over the metal

face of the sandwich panel on the airstream side of the casing shall be completely covered with metal strips.

Note: Metal-faced sandwich constructions is not intended to include foil-faced insulation.

5.4 Air Handling Unit motor selection

Motor IP ratings: Typically IP55 is considered adequate for most applications – higher IP ratings may be warranted

for specialized applications.

Thermistor protection is normally provided for all motors 75kW and over as standard, however for motors under this

size thermistor protection must be specified if required to be fitted.

Motors are generally based on 400V 3 Phase 50Hz 4 pole motor selections due to their lower noise and vibration

levels with the following standard range of motors sizes available:

0.37 2.2 11 37

0.55 4.0 15 45

0.75 5.5 18.5 55

1.1 7.5 22 75

1.5 9.5 30 90

Alternative single phase motors are also typically available up to 1.5kW.


Air Handling Units


Motor speeds are determined by the number of poles as follows:

5.5 Air Handling Unit coil selection

Coils are a highly configurable component of Air Handling Unit’s and will be selected by the manufacturer to suit the

design duty. There are several important parameters to note for coil selection that influence the geometry of the

Air Handling Unit, connections required and manufacturers selection inputs.

Parameter name Range of Values

Number of rows 2, 4, 6, 8, 10, 12

Fin spacing 236, 316, 394, 472

Tube material Copper

Fin material Aluminum or stainless steel

Maximum single coil height 1270 mm (40 tubes)

Maximum single coil width 3150 mm

Tube diameter 9.5 / 12.7 / 15.8

2 Pole = 48 rev/s

4 Pole = 24 rev/s

6 Pole = 16 rev/s

8 Pole = 12 rev/s
