lib-acoustic-rating

lib-acoustic-rating is a Javascript library which calculates acoustic rating requirements for IFC-data according to SIA 181.

Installation

Use the package manager npm to install lib-acoustic-rating.

npm install @vyzn-tech/lib-acoustic-rating

Usage

import CsvConverter from '@vyzn-tech/lib-acoustic-rating/dist/csv-converter'
import { AcousticRatingCalculator } from '@vyzn-tech/lib-acoustic-rating/dist/calculator'

const items = new CsvConverter().convertToComponents(csvString)

const calculator = new AcousticRatingCalculator(
  items, //                               required => see CSV
  externalAcousticRatings //              required => see External-Acoustic-Ratings
  // additionalNoiseSensitivityMap        optional => see Noise-Sensitivity-Map
  // additionalAirborneNoiseExposureMap   optional => see Airborne-Noise-Exposure-Map
  // additionalFootstepNoiseExposureMap   optional => see Footstep-Noise-Exposure-Map
  // additionalSpectrumAdjustmentTypeMap  optional => see Spectrum-Adjustment-Type-Map
)

console.log(calculator.calculate())

Expected Input

CSV

Column	Description	Supported Values	Example	Comment
GUID	An IfcGloballyUniqueId holds an encoded string identifier that is used to uniquely identify an IFC object.	22 character length string "0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz_$"	01$34_67$9_BsbEFbH$JK_M	GUID(same as original IFC) or UniqueLabel (unique string)
Entity	In an IFC model, project information is represented as a series of IFC entities. Each IFC entity contains a fixed number of IFC attributes as well as any number of additional IFC properties. The IFC schema includes several hundred entities, of which the building element-type entities (such as IfcWall and IfcColumn) represent only 25.	IfcWall IfcSlab IfcRoof IfcSpace IfcZone IfcBuilding	IfcWall	ElementType Could be remapped in an interface to match the request
PredefinedType	only required for IfcSlab: The predefined type based on IFC.	FLOOR BASESLAB ROOF	FLOOR	See Entity
ParentIds	The ID of the parent element (IfcRelation/ IfcRelToGroup)	A value from column “ID” of another row or null (empty cell)	01$34_67$9_BsbEFbH$JK_M	Will be the result of the link service
Name	only required for IfcZone and IfcBuilding: Bezeichnung respektive Name, welcher sich von anderer Nutzungseinheit oder anderen Gebäude unterscheidet	frei (string), beispielsweise Nutzungseinheit_1, Nutzungseinheit_2,... Dach Fluchtweg_1, Bauprojekt, Nachbargebäude	Nutzungseinheit_1	User input - ideally to be inputted on the platform / second option would be IFC input
AcousticRatingLevelReq	only required for IfcZone	Mindestanforderungen, Erhöhte Anforderungen	Mindestanforderungen	User input
Status	only required for IfcZone and IfcBuilding: Status of the element, predominately used in renovation or retrofitting projects. The status can be assigned to as "New" - element designed as new addition, "Existing" - element exists and remains, "Demolish" - element existed but is to be demolished, "Temporary" - element will exists only temporary (like a temporary support structure).	new, existing , temporary	new	ConstructionType Missing option “temporary” should be added
IsExternal	Indication whether the element is designed for use in the exterior (TRUE) or not (FALSE). If (TRUE) it is an external element and faces the outside of the building	TRUE FALSE	TRUE	PositionAgainst Could be remapped in an interface to match the request
OccupancyType	Occupancy type for this object. It is defined according to the presiding national code.	Werkstatt, Empfang, Warteraum, Großraumbüro, Kantine, Restaurant, Bad, WC, Verkauf, Labor, Korridor, Wohnen, Schlafen, Studio, Schulzimmer, Wohnküche, Büroraum, Hotelzimmer, Spitalzimmer, Ruheräume Therapieraum, Lesezimmer, Studierzimmer	Wohnküche	User input - Since that is a national standard the options should be in german
CelestialDirection	Himmelsrichtung 8 options	N, NE, E, SE, S, SW, W, NW	SW	Orientation Could be remapped in an interface to match the request
CenterOfGravityZ	Gravitationsschwerpunkt des Raumvolumens [m]	-99.99 to 99.99	3.43	Should be produced by the REF model
