  1. Question 7-3 Could environmental considerations lead the design process or is it a natural side effect of product optimisation ?

  2. AbcdSpecial reportQuestion 7-3 Could environmental considerations lead the design process or is it a natural side effect of product optimisation ? Answer: Improvements are not a natural side effect. • To be most effective environmental issues must be considered throughout the design process taking into account the whole of a product life cycle from concept to disposal or in other words from “cradle to grave”. • However, environmental considerations cannot be the only parameter driving a product development, but must form an integral part of it. • There are often many equally good answers to a technical question. The parameter “environment” can then become decisive and thus a leading factor.

  3. AbcdSpecial reportQuestion 7-3 Example: Development of a new range of vacuum interrupters using “A Design For The Environment Approach” All stages from “cradle to grave” considered – some examples: 1) Development process: reduction of short circuit tests by ten shifts by computer modelling  saving 120 MWh or 150 k€ 2) The new design: weight reduction by 40 % leading to product life span savings of 2 700 tons or 8 000 k€ 3) Manufacturing process: • Surface treatment: reduction of fresh water consumption by 6000 m3 over product life span due to new design & process • Seal-off: reduction of electricity consumption by 40x106 kWh over product life span due to improved seal-off method increasing at the same time the furnace capacity by factor of 2,6. • Conditioning / testing: replacement of SF6 by compressed air 4) End-of-life disposal: elimination of all toxic materials / additives
