HOTREC | Energy Efficiency Report

24 / 36

An energy recovery system has also been installed on the exchanger of the water chiller to preheat the
domestic hot water used by their clients, which allows them to reduce substantially their gas consumption.
As part of the Departmental Climate Plan, the Hôtel Martinez received in November 2017 a Climate Energy
Trophy in the “Development and Creativy” category by the president of the departmental council.The
Hôtel Martinez has been Green Globe-certified since 2010 and has adopted more sustainable practices
in all of its activities. Regarding water consumption, the clients can choose the frequency of cleaning
for their bed linen and their towels. The hotel installed next-generation faucets equipped with aerators
in the bathrooms and dual flush toilets. The hotel is also largely engaged in waste sorting, recycling and
partnership with charitable organizations. In 2015, the hotel also invested in a dehydrator of organic
waste, which allows them to reduce organic waste volume by almost 90%. In regards with safeguarding
biodiversity and safeguarding bees in particular, the hotel sponsors a beehive located in the Gorges de
Daluis (Alpes-Maritimes) with the association “Un toit pour les abeilles” (A roof for bees).
France : Hôtel Martinez (Cannes)
Between 2016 and 2018, the hotel implemented many actions to reduce
its energy consumption. They installed more energy-efficient equipment,
such as a more efficient water chiller for the air conditioning of the entire
building and more efficient motors for the elevators, which are also
capable of energy recovery. The lightning of the building’s façade has been
equipped with LED. During renovation works, low-energy light bulbs have
also been installed throughout the entire hotel, the insulation of exterior
walls has been improved and the brightness of the corridors’ lighting is
dimmed by half automatically by night and by day with a motion detector.
A temperature management system has been put to control the rooms’
temperature, depending on whether they are occupied or not.
France: NOMAD Hotel Le Havre Gare (Le Havre)
Environment is a priority at NOMAD Hotels, with
the objective to reduce as much as possible the
environmental footprints of their hotels, from their
construction until their exploitation. Their air handling
unit is equipped with an energy recovery system. The
parking area is illuminated with LED light poles. The
domestic hot water is heated by two complementary
systems: 120 m2 of solar panels on roofs and high-
temperature heat pumps. By design, the elevators were
also equipped with an energy recovery system. To
prevent the loss of energy from the building fabric, the
windows are double glazed and the concrete walls and
the insulation are very thick.
Opened in 2015, the Nomad Hotel Le Havre has been
designed to be environmentally responsible.
