Appendix 4. Production of input data for life cycle assessment.
3.1. Water Sector Case
The modelling the manufacture of water distribution network’s pipelines was based on the
following assumptions:
- The materials used for the pipeline is HDPE,
- Pipeline diameter, i.e., the smallest diameter is 63mm,
- The weight of one meter of pipeline for the chosen weight is 3.8kg.
- The total length of the network is not available. Therefore, the calculation is performed
for 100 km.
Thus, the amount of CO2 resulting from 100km of water pipeline is 148.2 MtCO2eq.
3.2. Urban Planning Sector Case
3.2.1. Embodied Energy
Modelling of the generated emissions during the manufacture of building materials
(embodied energy), and the consumption of electricity and natural gas (operational energy)
has been established on GEMIS based on approximations necessary for the production of
input data.
This the quantification was based on the weight of the materials used and the weight of the
dwellings of each wilaya, calculated as follows;
1. Total number of dwellings in each wilaya for different types of housing programs.
2. Estimate of the proportion of materials used for each material (concrete, brick and
steel), the calculation of proportions was based on the characteristics of each material
(e.g., amount of steel in the reinforced concrete).
3. The total weight of the three materials represent the total weight of one dwelling for
each type of program.
4. GEMIS modelling considers 1 tonne of a housing unite with the specific proportions
(%) of each material.
5. The same calculation applies to individual houses (self-build) assuming an R+1 based
on the quantitative reports provided by the architects and projects managers.
The conversion figures for each material are as follows:
- The conversion of reinforced concrete is based on its given density 350 kg/m
3
or 150
kg/m
3
in tonnes.
- The conversion of the brick is based on the surface of the brick used, where a double
brick corresponds to 0.06m² and 3.5 kg per unit
- The conversion of steel is based on its proportion in reinforced concrete, which is on
average 5%.
