"Energy Efficient Production - Interdisciplinary, Systemic Approach through Integrated Simulation";
If the main concern of manufacturing companies was increasing the productivity, reliability, flexibility, and quality of the industrial process, more recently the energy efficiency of the production process and facilities came under scrutiny. To enhance the energy-efficiency of production facilities detailed information regarding the production processes, heat emissions from machines, operation level and occupancy analysis are necessary. In this context, the present paper describes an ongoing research effort that aims to develop a systemically integrated model of an energy efficient production facility. In this context we demonstrate initial results of the implementation of an integrated simulation approach for a specific industrial facility. On the case study of an existing facility the different levels of energy in-and outputs were analysed; starting from machines and production systems, user behaviour and building services related requirements, to the building envelope of the facility. The collected information was further processed to develop a new building design. This layout provides the basis of an initial building performance simulation model. The generated model is part of the integrated simulation approach and used as a starting point to address the impact of different design- and building operation options on the indoor climate and energy performance of the industrial facility. The goal of the integrated simulation approach is to evaluate a production facility not separately for individual mandates pertaining to production process, building envelope, and systems, but in a coupled and integrated fashion. Based on results of thermal simulation a first life-cycle costs model is developed, upon which the crucial points for decision-making process in planning of energy-efficient industrial facility can be identified.
