Energy efficiency partnership between Lindner Hotels and Siemens
More than 10% savings thanks to energy management

The efficiency of building systems depends not only on high-quality planning, execution
and commissioning but also on professional building operation. Yet even highly automated,
well managed heating, ventilation and air-conditioning systems have hidden efficiency
potential, as demonstrated by Lindner Congress & Motorsport Hotel at the Nürburgring.
With support from the Building Performance Optimization remote service from Siemens, the
hotel plans to cut its energy consumption by at least 10% through zero-investment and
investment measures with a payback period of less than one year.
Energy-efficient building operation and the collection of energy consumption data has always been
part of the Lindner Hotel Group's strategy for operating its hotel properties. As early as 1990, the
company began recording the energy data of Lindner hotels on a monthly basis and combining this
information with its occupancy schedules and energy rates in a way that enabled the creation of
key figures, known as “benchmarks.” This relatively crude system for recording energy
consumption was sufficient for assessing the hotels’ energy use until around 2006. Motivated by a
disproportionate rise in energy prices, Lindner Hotels AG launched its internal “Energy Save”
offensive. The message at the time was this: Each of Lindner’s 1,000 employees was to save one
euro in energy costs each day. Time-limited power purchasing agreements, which expired in 2006
and would have subsequently led to approximately €350,000 in added costs per year, were the
external impetus for this concerted appeal to the staff to save energy.
