Due to constantly rising prices, energy consumption is a considerable cost factor in every production plant - lighting, heating and air conditioning contribute significantly to this. Current building automation systems, however, are only based on target values. This ensures appropriate working conditions, but there is no demand-oriented control.
The research project »BIG« aims at reducing the energy demand of support processes of manufacturing companies by coupling production planning and control, weather forecasts and building automation. Studies forecast savings of 30 to 40 percent in peripheral energy costs when the above parameters are combined.
Germany-wide there are more than 50 companies offering systems and/or hardware components for building or home automation. However, these are limited to private houses and thus the classic HVAC (Heating, Ventilation and Air Conditioning) parameters. Solutions for production companies and their individual requirements, possibilities and boundary conditions do not exist on the market at present.
There are a large number of patents for building automation, which deal with temperature control, ventilation or lighting in isolation. In addition, there are patents for predictive control after occupancy and for adaptation to weather forecasts, which, however, do not focus on the individual requirements of production and, furthermore, only offer isolated solutions instead of an integrated concept.
The project »BIG« is intended to make an important contribution to energy system transformation and the achievement of climate targets by means of an integrated concept: Above all, the networking of different building technologies as well as coupling energy production and energy use is expected to lead to considerable savings compared to previous approaches which considered the energy consumption individually and in isolation. The claim to develop a manufacturer-independent solution holds a high innovation potential and many advantages in terms of flexibility and cost-effectiveness.
Since different approaches to energy saving are not considered individually as in the past, the product offers a high degree of innovation and a clear competitive advantage for users. The application of the software leads to savings in energy costs, which in turn leads to an increase in the added value of the products.
The development of such a building automation system means a first-time integration of all possible applications in this field. The use of information from other systems and hardware control tailored to these systems contributes to energy savings with increasing control performance, taking into account the new possibilities of building automation. From now on the transfer to the peripheral areas of the production under recourse to the production planning is possible.
Various studies assume a high savings potential through intelligent building automation: In the manufacturing industry, for example, 17 percent of final energy consumption is caused by room heating and lighting. For an exemplary, medium-sized production company in Germany, this results in costs of around €700,000 per year for space heating and €150,000 per year for lighting. This results in annual savings potentials of around €280,000 to €340,000.
The combination of individual automation functions targeted by »BIG« enables further savings of 33 to 40 percent compared to their isolated use. According to studies, a combination of daylight utilization, presence control, occupancy planning and load shedding can also be expected to save up to 40 percent of electrical energy in lighting.
