Saving work and -material numbers explained

The saving_material and saving_work variables per part concern the saving part of the investment, split into material and labour. This affects the final calculation of CO2 emissions and the ELG.

saving_material: cost saving part of the investment per unit for material (excluding VAT). saving_work: cost saving part of the investment per unit for labor (excluding VAT).

As a rule, the savings share is on average 92.5% (between 90 and 94%) of the investment in material and labour.
