5 2 APPLICABLE STANDARDS There are a number of requirements in the National Construction Code as well as relevant Australian and international standards that relate to passive chilled beam design and selection. Codes and standards referenced in this specification include: General Requirements NCC/ BCA : National Construction Code / Building Code of Australia AS3500 : National Plumbing and drainage code State plumbing regulations s AS : The use of ventilation and air conditioning in buildings Part 2: Mechanical Ventilation in buildings AS3666 : Air Handling and water systems of buildings Microbial control Eurovent : EN14518 BIM-MEP AUS Page 5

6 3 MODELS 3.1 Model workflow One of the principle aims of BIM-MEP AUS 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-MEP AUS generic design families provide a catalogue of sizes (types) that allow designers to spatially model to LOD 300 as well as specify the passive chilled beam 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. The passive chilled beam lengths (mm) are customizable in 100mm increments with a minimum length of 600mm and maximum of 5400mm. Commonly used lengths are 1800, 2100 and 2700mm. Passive chilled beams are available in widths from mm. Design firms with content libraries can pre-populate these passive chilled beam 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. 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-MEP AUS compliant this should be readily achieved. Manufacturer s models are preferably generated from the BIM-MEP AUS Industry Foundation Models (IFM) and are a single type family that has the passive chilled beam geometry needed for the virtual build plus the manufacturer data for the specific passive chilled beam to be supplied to the project. BIM-MEP AUS Page 6

7 BIM-MEP AUS certified manufacturer models are fully interchangeable with the generic design models and provide: Accurate geometry Performance data Full BIM-MEP AUS 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-MEP AUS 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-MEP AUS 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. 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 modeller s 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.

8 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-MEP AUS 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-MEP AUS Product Data Template shared parameters MCM geometry model with supporting BIM-MEP AUS Product Data Template Excel file. To allow efficient and reliable data exchanges, it is critical that the BIM-MEP AUS 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.

10 5 PASSIVE CHILLED BEAM SPECIFICATION The following guidance has been developed through the industry consultation process for this specification and provides advice in relation to passive chilled beam selection and completion of the quality/performance schedules. 5.1 Passive chilled beam selection The majority of new buildings that utilize passive chilled beams aim to leverage the benefits of waterside cooling in the space to increase energy efficiency and occupant comfort. There are other benefits to gain including acoustics. When selecting passive chilled beams as a method of providing cooling to a space it must first be ensured the operating chilled water temperatures are above the space dew point in order to avoid condensation issues. Control strategies allowing for high humidity days are recommended. 5.2 Passive chilled beam installation arrangements Installation of passive chilled beams is to be as per manufacturers guidelines and instructions. Due to the cooling method of passive chilled beams dimensional requirements between the underside of the floor above to the chilled beam and the chilled beam clearance from the ceiling become important due to the buoyancy forces involved. 5.3 Controls Chilled beams should be grouped into zones to suit the load characteristics of the building and any other zoning requirements. Each zone will have a single two way valve which is controlled by an appropriately located thermostat within the zone. The chilled water temperature serving the chilled beams should be high enough to prevent condensation forming on the chilled beam 5.4 Connections Chilled and heating water pipes are connected through flexible hoses using a threaded BSP or o-ring type fitting. 5.5 Unit Selection The length of the chilled beam will be selected based upon the heat load requirements of the room.
