## 4 Results
### Analysis of Economic Impact
Since energy costs fluctuate continuously based on market prices, the fourth column (energy cost) of Table 4 reflects the average value in euros per MWh (EUR/MWh), derived from the monthly report in [55];
* Finally, the fifth column (economic cost) of Table 4 presents the result of multiplying the third and fourth columns, providing an estimate of the potential economic savings that could be achieved by managing the heating to comply with recommended threshold (not exceeding >21 \({}^{\circ}\)C, first row, yellow background). Following this methodology, the results for each month are analysed as follows (see Table 4):  
* November. Temperatures exceed 21 \({}^{\circ}\)C (with heating on) for 29.9 h, where half (15.7 h) corresponds to the first degree (21-22 \({}^{\circ}\)C), monitored as 7.92 MWh. It means (estimating an average energy cost of 63.44 EUR/MWh) a potential savings of over EUR 500. * December. Temperatures exceed 21 \({}^{\circ}\)C (with heating on) for 18.6 h, where the majority (12.3 h) corresponds to the first degree (21-22 \({}^{\circ}\)C), monitored as 5.13 MWh. It means (estimating an average energy cost of 72.19 EUR/MWh) a potential savings around EUR 370. As already noted in Section 4.5, in December, heating was used more appropriately (compared to November), as now quantitative demonstrated. \begin{table}

**\textgreater{}23 \({}^{\circ}\)C** & 0.4* January. Temperatures exceed 21 \({}^{\circ}\)C (with heating on) for 16.5 h, where majority (12.6 h) corresponds to the first degree (21-22 \({}^{\circ}\)C), monitored as 4.49 MWh. It means (estimating an average energy cost of 74.09 EUR/MWh) a potential savings around EUR 330. These values are similar to December, as noted in Section 4.5. * February. Temperatures exceed 21 \({}^{\circ}\)C (with heating on) for 92.8 h, monitored as 25.08 MWh: the highest value, as noted in Section 4.5. However, the estimation in February of average energy cost decreased to 39.93 EUR/MWh, which represents an estimated economic cost around EUR 1000. Even so, it means a significant potential savings.
