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 iC clean energy solutions GesmbH office@ic-group.org www.ic-group.org www.ic-ces.at

Hot Water Consumption Especially for 4* and 5* hotels up to 2000 L/m²a up to 100 kWh/m²a pool heating, pool feed water, laundry, etc.

Reference hotel case (worst case) 100,00 kWh/m²a 4.600,00 m² 460.000,00 [kWh/a] … demand 511.111,11 COPel 0,9 … consumption 0,10 EUR/kWh 51.111,11 EUR/a

Reflection on ST vs HP Careful, the above calculations were not taken into consideation the piping costs for the required distribution, but, in conclusion: Summary on the expected paybacks Solar Thermal Hot Water Preparation Hot Water Preparation through a HeatPump 10 cEUR /kWhel 16 cEUR/kWhel 10 cEUR /kWhel 16 cEUR/kWhel 10% interest 15 to 20 years 10% interest 4 to 7 years 5 % interest 9 to 15 years 5 to 10 years 5 % interest 3 to 6 years 2 to 5 years

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 iC clean energy solutions GesmbH office@ic-group.org www.ic-group.org www.ic-ces.at
