Life-Cycle Inventory (LCI) For the comparative Life-Cycle Assessment of a restoration and renovation of a traditional Danish farmer house

This document provides the Life-Cycle Inventory of the study comparing the environmental performance of the restoration (Scenario 1, also mentioned as "S1") or renovation (Scenario 2, "S2") of a traditional Danish farmer house. The LCI is used as input for the life-cycle impact assessment phase in the LCA where the inputs and outputs of elementary flows in the LCI are characterized as potential impacts on the environment. The LCI is based on primary data from the "Apprentices' House" combined with secondary data from materials specific environmental product declaration and the large LCI database ecoinvent v3.

The file contains several spreadsheets organized as follows:

Thicknesses,S1 - Reports the materials and their corresponding thicknesses used for walls, ceilings, floors and insulation in S1

Thicknesses, S1b - Reports the materials and their corresponding thicknesses used for walls, ceilings, floors and insulation in S1b

Thicknesses, S1c - Reports the materials and their corresponding thicknesses used for walls, ceilings, floors and insulation in S1c

Thicknesses, S2 - Reports the materials and their corresponding thicknesses used for walls, ceilings, floors and insulation in S2

Surfaces - Reports the area of all surfaces of the house (walls, ceilings, floors) for all scenarios. 

Bill of materials - Sums up the list and quantity of all the materials used in all scenarios, providing details as to the quantity kept from the actual house, as well as the new input and output of materials during the restoration/renovation

Heat loss, S1 - Provides details for the calculation of heat loss through the building envelope of the house in Scenario 1

Heat loss, S1b - Provides details for the calculation of heat loss through the building envelope of the house in Scenario 1b

Heat loss, S1c - Provides details for the calculation of heat loss through the building envelope of the house in Scenario 1c

Heat loss, S2 - Provides details for the calculation of heat loss through the building envelope of the house in Scenario 2

Parameters - Describes the main parameters used in the LCI and their corresponding uncertainty

LCI Materials - Provides the full breakdown of the processes created and used for the LCI modelling on OpenLCA

LCI Building - Provides the full breakdown of the processes created and used for the LCI modelling on OpenLCA
