The Corinthia Hotel Lisbon, currently the biggest five
star hotel in Lisbon, claims to be the most energy efficient hotel in the city.
A refitting project started in 2011, developed in a
partnership with Galp Energia and ISQ Energia, two energy companies operating
in Portugal, increased its energy efficiency dramatically.
The company was committed to reduce its energy
consumption and at the same time its CO2 footprint by implementing efficient
systems, and by the use of renewable energy sources.
The measures included the optimization of the water
heating and acclimatization systems, lighting hardware and software and
installing both a cogeneration and solar stations.
By the end of the refitting, the hotel was able to
save 2,02 GWh/year. That’s 22% of its previous yearly energy consumption.
Replacing around 6300 halogen light bulbs for LED
alone, granted a 202.599€/year save. The equivalent of 635.181 KG CO2/year or
31.753 trees.
