same category and facilities, depending on the installation design, technology,
maintenance and control. This difference in terms of energy consumption between an
environmentally friendly hotel that has implemented measures to preserve natural
resources and a hotel built during the 1970s and 1980s and not yet refurbished can be
from 30% to 60% with all other factors being equal (same climate, same needs).
Future scenarios go from reduction of energy and increase the renewable energies.
Mallorca have actually facilities of solar, wind and wastes, and a big potential in hydro,
biomass and shallow geothermal. Smart Energy measures in hotels have to be carefully
selected in order not to endanger the Electric system and increase the maximum
Renewable energy in the system. The highest energy demand in hotels comes from
HVAC devices, raising the demand of electricity which is the common source of
energy in all hotels and the easiest to save and to store with buffer tanks.
Accordingly, priority should be given to control energy used in the guests’ rooms, for
example, by using simple controls to ensure that practically all electrical appliances are
turned off when guest rooms and corridors are unoccupied. A better distribution of the
building’s layout and an improved control of energy use result to a potential energy
saving between 15 to 30%. The total energy consumption for hot water may represent
between 12%-36% of the total energy consumption, which varies according to the hotel
category and weather conditions. Average annual energy consumption may reach 1300-
5000 kWh per bed. Installing between 1-2 kWp per bed we could arrive to a
sustainable scenario.

The potential average annual energy savings from solar collectors reach 1200
kWh/kWp [9]. Thus they can be used to cover a significant part of the energy demand
(80%), and if combined with smart chillers, they can also be used for cooling. The use
of heat recovery from the cooling system (i.e. the recovery of waste heat from cooling
