With an energy saving of 40%, the energy management system emsyst 4.0 has convinced the Baden Württemberg Minister of the Environment Franz Untersteller. He supports broad use of the system.
Minister of the Environment endorses energy management
With innovative energy management from Oberboihingen, BMW saves 40 percent energy
Franz Untersteller (Green Party) spent one and a half hours on Friday (20 November) in the Stuttgart BMW dealership to gain an insight into the energy management system emsyst 4.0 and to understand exactly how it works as a digital node for all building service equipment and machinery.
The energy-saving system has been in use there for just under a year, and has cut electricity and heating oil consumption by 40 percent by reducing waste. “I’ll make sure you get all the relevant contacts so that your system becomes established in businesses even faster” promised Baden-Württemberg’s Green Party Minister of the Environment, speaking to emsyst developer Friedrich E. Riempp.
The software has been market-ready since 2013 and is currently used in 20 companies throughout the state – with similar results to those at BMW. It was implemented there in January as a logical next step in the building services the Oberboihingen-based company R.I.E.MPP has been supporting at the dealership since 2011.
So far, the Stuttgart BMW branch is the first of 50 authorised dealerships around Germany which have adopted the environmental fitness program. Dealers in Mannheim and Saarbrücken have already made enquiries. The core principle behind emsyst 4.0 is that it prevents waste by logging energy consumption using sensors, then controlling and verifying consumption.
This includes automatically turning down the heating in a room when a window is opened and turning it up again when the window is closed. If there is no movement in a room, the lighting dims or switches off. These are just two features of the system. “We save 40 percent of our former energy costs of EUR 600,000 per year” says Werner Pfanzelt. The Commercial Manager has invested EUR 1.2 million in the system, and expects a return on investment within four years.
During his tour of the 10,000 square-metre dealership with its 350 employees in the showroom, workshop and administration, the minister stated that he was impressed by the fact that the software communicates its data not only via cable but also wirelessly via radio. This makes the solution easy to install even in existing buildings and very versatile.
As he was already planning a facility upgrade, Pfanzelt cooperated with the company Riempp and they jointly drew up an investment and action plan to reduce the energy consumption in the building. At a cost of EUR 800,000, the entire lighting was converted to LED lights, which are up to 60 percent more efficient. This alone delivers annual costs savings of EUR 160,000. The emsyst 4.0 energy management system, which Riempp developed in the context of the federal goverment’s decision to phase out nuclear power, accounts for an investment of EUR 200,000. A photovoltaic system on the roof of the multi-storey car park for
EUR 150,000 is designed for a capacity of 80 percent of the company’s energy consumption and will reduce the electricity supply from the public grid by another 30 percent from 2017.
Untersteller was accompanied by Green Party legend Rezzo Schlauch, who was secretary of state in the Federal Ministry of Economics up to 2005,
and state MP Nikolaus Tschenk. The event, in the run-up to the state election in February, was an ideal opportunity to demonstrate that ecology and cars can go hand in hand.
