The minimal investment cost, flexibility and expandability of the built structure were the highest priority planning aims in the development and planning of industrial facilities. With the sharpening of building codes and the upcoming European polices on climate protection and energy efficiency, the life cycle optimization is starting to gain importance among industrial investors. Optimized, highly efficient building hull and building services play crucial role in the realization of an over-all energy-concept of modern industrial facilities. On the case study of an energy efficient industrial facility within the research project INFO (Interdisciplinary Research for Energy efficient Production), a tool for ecological and economic life cycle analysis - assessment of life cycle costs and emissions of the façade (EEFA) was developed. For the proposed building model of industrial facility three different façade-typologies (metal sheets, metal-sandwich panels, wood panels) were simulated and calculated by the tool. In terms of ecology (CO2 emissions) the wood-based façade features the best performance; however is the most expensive regarding the initial costs, which would have been a knock-out criterion when planning an industrial facility in the past. Nevertheless, life cycle cost related findings imply that even though the examined typologies feature large differences in the initial cost, after a period of 36 years of life-time all three façade-types sum up to the same amount of life cycle costs. This paper argues that in order to achieve the goal of sustainability a long term view is necessary, as well as further development of planning tools which support decision-making process in early design phases.
