Characteristics Hotel Sector Large hotel chains in Europe
mostely city locations / city tourisms / occupation all year round have established benchmarking systems standardisation allows for high end solutions towards energy efficiency attract manufacturing companies proving energy efficiency solutions energy savings potential is typcially between 2 % and 5 % (max. 10 %) solar thermal energy is considered as a viable source for DHW preparation /
other renewable energy solutions depend on philosophy of the owner/s
Individual hotel operations less standardisation, if any more often focusing on seasonal tourism less stable ownership energy savings potential typcially above 10 % , up to 30 % RE are typcially not considered as a viable solution

Reflection on ST vs HP Careful, the above calculations were not taken into consideation the
piping costs for the required distribution, but, in conclusion:
Electricity price is key to achieve a viable investment in RE Low interest rates are supportive All year round operation is recommended for Solar Thermal HP system outperforms ST at the availability of low cost energy ST becomes interesting at 16 cEUR/kWhel and above
