Résumé

The energy demand of buildings within the hospitality sector, notably hotels, is high and diversely distributed. Furthermore, it is rising due to growing needs of convenience per guest. Determination and analysis of electrical and thermal energy is necessary to achieve reduced energy loads. This is hindered by missing concrete data on loads.
Therefore, 24 buildings linked to the hospitality sector are equipped with devices for gathering electrical and thermal energy load data in detail from January 2019 to January 2021, a period markedly affected by the COVID-19 pandemic. The data is used for identifying possible energy enhancements and developing a model predictive control (MPC) algorithm for adapting efficiency improvements. A new methodology is introduced by a classification system for categorizing the hotel buildings in terms of utilization and energy efficiency. The buildings are further differentiated into the four application categories conference, journey, event and wellness. This study also explores the integration of renewable energy sources, including photovoltaic (PV) and block-type thermal power stations (BTTP), combined by district heating (DH), besides conventional oil/gas boilers. A specific concept for collecting data in every category is developed and instrumentation is installed to measure energy demand spatially and temporally resolved for a period of two years.
The unique context of the pandemic provides insights into the resilience and adaptability of energy demand patterns in the hospitality sector. By analyzing the collected data, key energy improvement opportunities are identified in relation to the acquired data for base loads, typical peaks and mid-term impacts like holidays.
