Italy: Autogrill Villoresi Est
Autogrill Villoresi Est is an example of Italian restaurant strongly engaged in energy efficiency. The service
area embodies a number of innovative, expert solutions that optimize energy consumption and resource
use while safeguarding nature and the environment. These are based on the international best practices
for environmental protection. Villoresi Est is made of eco-friendly, recyclable building materials, and the
entire skeleton of the building is constructed of PEFC-certified glued laminate timber from sustainable
forests. The building is constructed of eco-friendly, recyclable materials. Villoresi Est features numerous
technological innovations including a solar roof that harvests energy from the sun and a closed-circuit
geothermal plant whose 25-meter-deep geothermal probes can supply 380 kilowatts of geothermal
energy. The building is equipped with a system to collect and recycle rainwater and groundwater, which
are used in the air conditioning, green irrigation, toilets and fire protection system.
Spain: HIPOTELS Bahía Cala Millor Hotel (Mallorca)
The reform consists of the conversion of an apartment building
with 30 years of antiquity into a 4* hotel. A dining room for clients,
a cooking show and a central kitchen are added. Reorganize
noble areas and delete the apartments on the ground floor
and basement to the new spaces. The envelope of the building
is sought by replacing windows and covering cone partition
walls Insulation around the exterior perimeter, achieving energy
certification level B.
The addition of the thermal envelope suggests that will lead to
a decrease in losses of 25% by heat transmission of the exterior
facades. Of the same way the losses by windows and large
windows they will be reduced by 35%. The combination of both
measures implies a reduction 28.30% of the thermal losses due
to the envelope of the building. Heat recovery from boiler fumes
provide us with a 9% reduction in the cost of fuel, going from
96% to 105% over PCI, using energy according to its quality, there
where is able to provide the highest performance.
The high temperature heat recovery of the refrigerating machines allows reaching a reduction 15% in fuel
expense being indicated for heating ACS and any other use that requires high quality of energy. The solar
panels allow a 20% annual reduction in consumption of energy, since its use is not only for production of ACS
but it is distributed where it is needs according to the level of energy produced.
