Optimizing the building's energy uses.

The number of French hotels, cafés and restaurants represents approximately 7% of all commercial buildings in France[1]. These buildings are now directly concerned by the reduction of their energy consumption with the implementation of the tertiary decree on the 1^st of October 2019. 

Through this decree, the law requires all tertiary buildings (over 1000m2) to significantly reduce their energy consumption in the coming years.

Notice: Article L. 111-10-3 of the French Building and Housing Code requires the implementation of actions to reduce final energy consumption in existing buildings for tertiary use. This is in order to achieve a reduction in final energy consumption of at least 40% in 2030, 50% in 2040 and 60% in 2050, compared to 2010.

These buildings are major energy consumers: 241 kWh/m2/year, with an average energy bill of 21.6 €/m2/year¹. In a hotel, there are many expense items: lighting, kitchen, laundry, heating, air conditioning, ventilation… Many people travel on a daily basis and more particularly customers, who are often less careful to their energy expenses than at home: a customer consumes on average twice as many liters of water in a hotel as at home.

Considering the reduction of energy consumption is therefore an important concern for the Ibis Confluence hotel, both for regulatory and environmental aspects. The challenge is therefore to find solutions to reduce energy consumption and to monitor their evolution over time without influencing the comfort of users.
