Theoretical and Practical Aspects of Electrical Equipment Eco-Design

In the last time some factors and especially the environmental protection requirements have forced to add the ecological criterion for design of electrical equipments, within a new Eco-design concept. The essence of this concept consists in the integration of environmental aspects at project phase, taking into account full life cycle of product. The work presents some theoretical and practical aspects of Eco-design for electrical equipments. Relationship between environmental management systems and Eco-design is underlined. Some key indicators for measuring the environmental performances are exemplified. The actual eco-design conception combines Qualitative Assessment of Life Cycle Criteria with a quantitative method based on the Product Carbon Footprint. The calculation of the last indicator means the quantification of the greenhouse gases emissions (kgCO2 equivalent) during the life cycle of products and services. The maintenance and repairs activities of electrical equipments have also some negative impacts on environment (directs and indirect). The author proposed, as an original contribution, two relevant environmental performance indicators in this field: 1. The absolute indicator (Es)-CO2 emission involved into service [kg CO2]; 2. The relative indicator (es)-CO2 specific emission involved into service [kg CO2/euro] . These indicators assist the companies to find the losses and to establish the efficient corrective and preventive actions, to complete environmental data base and to compare the environmental performance between different management levels. The main advantages of eco-design application are: Creativity and innovation; Low manufactured costs; Superior quality of the product; More guarantees; “Green is better sold” .
