## 4 Data Analysis
### Initial Cost
#### 4.1.2 Manufacturing
It is expected that 20% of the labor cost will be allocated to the procurement of necessary tools for the manufacturing process [45], such as picks, shovels, brooms, and other implements, at a rate of USD 0.004 per adobe block for the extraction process. The heavy machine can reach values almost double the labor force [45], and the value is assumed to be USD 0.0272. This amount is referred to as TOTAL (E) and takes the value to USD 0.0276. [PERSON]. [7] undertook a comparative analysis of adobe production in three factories located within the province of Azuay, Ecuador. The energy consumption, comprising electricity and fuel, required for the extraction of materials, transportation of the raw material, and the production of the final product, was determined to be 52.54 kWh and 52.92 kWh for two and one of the factories analyzed, respectively. With regards to energy expenditure, the average monthly energy consumption for a block adobe production plant is 52 kWh. This suggests that each individual block of the adobe consumed approximately 0.067 kWh. As of the current date in Ecuador, the electricity tariff was fixed at 0.0920 USD per kWh by Resolution No. ARCERNN--009/2022 [46]. Consequently, the total energy cost for a single adobe block is 0.0061 USD (K). Regarding administrative expenses associated with the manufacturing process, it is essential to consider factors such as the upkeep of the workspace, remuneration for administrative personnel, and other indirect expenses that contribute to the cost of an adobe block. Although these expenses are projected to account for up to 60% of the direct costs in some projects [32; 47] within the construction sector in Ecuador, they can reach up to 20% of the direct costs [44; 45], as shown in the fifth row of Table 5.  
The expense associated with the creation of an adobe block measuring 10 \(\times\) 20 \(\times\) 40 cm amounts to USD 0.1637, which translates to 16 cents in United States currency. This price reflects the costs associated with the artisanal manufacturing and drying of the blocks as well as their extraction. The total costs and corresponding percentage of contribution for each section are listed, with the intention of discussing the results obtained, as shown in Table 5. \begin{table}
