BH.oM.LifeCycleAssessment.MaterialFragments.CombinedLifeCycleAssessmentFactors

An Combined Life Cycle Assessment Factors is aggregate class to compute final impact factors. This object is commonly created based on a EPD for cradle to gate metrics (A1 - A3) with addional project and site specific data added for relevant stages beyond the product stage.

Class structure

Implemented interfaces and base types

The CombinedLifeCycleAssessmentFactors is inheriting from the following base type(s) and implements the following interfaces:

Properties

Defining properties

The following properties are defined on the class

Name Type Description Quantity
EnvironmentalProductDeclaration EnvironmentalProductDeclaration THe Environmental Product Declaration as the basis for the life cycle assessment. Commnly outlines the metrics for A1-A3 modules, but might contain metrics beyond those modules. -
A4TransportFactors ITransportFactors Factors for computing the emissions relating to Module A4 which captures the impacts associated with the transportation of the materials and components from the factory gate to and from the project site. -
A5_3ConstructionWasteEmissions ConstructionWasteEmissions Factors for computing the emissions relating to the Construction and instalation process (A5). -
C2TransportFactors ITransportFactors Factors for computing the emissions relating to Module C2. Module C2 Transport impacts consists of any carbon impacts associated with the transportation of material from deconstruction and demolition to the appropriate final location, including any interim stations. -
C3C4WasteAndDisposalFactors WasteAndDisposalFactors Factors for computing the emissions relating to Module C3 (waste processing) and C4 (disposal). WasteAndDisposalFactors defines the end of life waste processing and disposal factors to be applied to the material fragment. These factors are applied in addition to any end of life factors provided by an Environmental Product Declaration, and can be used to fill gaps where no EPD data is available. If applied this will help populate all Climate change metrics available, with LandUseFactor being set to 0. -
