- •
An automated procedure for optimizing the design of structures is presented.
- •
There is a parabolic relation between the span length and the minimum energy.
- •
The energy reduction has an average cost impact of 3.23€ per square meter of deck.
- •
Since both criteria are dependent, 1€ reduction is equivalent to 4 kW h saving.
