### 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.
