• Achieve maximum energy efficiency: The primary goal was to bring the building technology up to date in order to significantly reduce energy consumption and optimize operating costs.
• Take important steps towards climate neutrality: The modernization aimed to contribute to environmental protection and reduce CO2 emissions.
• Further improve guest comfort: Despite the modernization, the refined comfort of the traditional hotel should not only be maintained but further enhanced through optimized heating, ventilation, and pool technology.
• Always be at the cutting edge of technology: The owner family aimed for a comprehensive modernization of the building technology to be future-proof.
• Modernization with minimal operational disruption: The entire renovation was to be completed within a short closure period (around six weeks) to minimize disruption to hotel operations.
• Optimize critical building systems: In particular, the heating supply (heating system, lake-bath heat pump), ventilation and air conditioning systems, and parts of the swimming pool technology were to be made more efficient.
• Central control and monitoring: Implementation of a central building management system for efficient control, regulation, and monitoring of all building services.
• Utilize sustainable energy generation: Installation of a photovoltaic system for self-generated electricity and further reduction of external energy demand.

Siemens supported Hotel Hochschober with a comprehensive modernization of its building technology, perfectly tailored to the hotel's specific requirements:

• Comprehensive system optimization:
  • Heating and hydraulics: Optimization of the hydraulic heating system, re-regulation of the entire system (from district heating converters to underfloor distributors), replacement of radiator valves, and substitution of approximately 35 rigid pumps with highly efficient, variable-speed pumps.
  • Ventilation and climate control: Renewal of ventilation systems with 38 direct-drive fans equipped with frequency converters and installation of CO2 sensors for demand-controlled operation.
  • Pool technology: Implementation of highly efficient Siemens heat pumps (150 kW) and new heat exchangers for the lake-fed pool, as well as retrofitting of the pool water technology in the wellness pools with flow optimization using frequency converters.
• Central building control and energy management:
  • Installation of a central building management system Desigo CC from Siemens for the integration, automation, and flexible control of all systems.
  • Implementation of the cloud-based energy and asset management platform Navigator from Siemens for visualizing, analyzing, and continuously optimizing energy consumption.
• Sustainable energy generation: Installation of a heavy-duty photovoltaic system (51 kWp) on the hotel roof.

Hotel Hochschober, located on the Turracher Höhe in Carinthia since 1929, is a traditional establishment with a unique location directly on Lake Turrach. It offers refined comfort and has recently modernized its building technology with Siemens' support to achieve maximum energy efficiency and enhance guest comfort.
