10. SUMMARY OF RESULTS AND SENSITIVITY

The table below shows the results from the top-down model in total savings per year. These calculations are based on the EU numbers from the EIA report.

For each product group in each country, a specific scale was assigned in an iterative process with representatives from Nordsyn authorities in each country. The total savings from the top-down model are in TWh/year.

The table below shows the total savings from the bottom-up model in GWh/year in 2030 for the products for which this calculation was performed. Note that bottom-up calculations were not possible for all products due to the lack of data, and this table thus does not show total savings in each country from the market surveillance of ecodesign and energy labelling.

Robustness of the bottom-up model. To examine the model's robustness, a sensitivity test was performed for refrigerators/freezers in Sweden. The results show that increasing the lifetime of products leads to higher savings due to a higher stock.

The table below shows the consequences of changing the assumptions. This is an example for refrigerators/freezers in Sweden. The first line shows the standard assumption. In this example, the sales numbers do not change. The first example is a decrease in the lifetime from 12 to 10 years, which causes the stock to decrease, and the savings thus decrease by 15%. In the second example, the lifetime is increased from 12 to 14 years. This causes the stuck to increase, and the savings then also increase by 14%. In the third example, the size of the refrigerator/freezer is increased by 10%, which increases the savings by 6%. In the last example, the volume is decreased by 10%, which causes the savings to fall by 5%.
