One of our most ground-breaking pilot projects is intended to generate energy for recharging an electric car. But you wouldn't imagine how ...by using an elevator!

This is possible thanks to a set of pulleys that are attached to the lift, which produces energy when the car moves down by gravity and uses it to recharge electric car batteries.

These eco-efficient elevators enable us to supply the hotel's recharging points with the energy needed to drive 30,000 km.

A good way to keep on contributing to looking after our environment, caring our planet.

Thanks to the highly efficient technologies used in our hotels’ air conditioning systems, you can now choose just the right temperature for you, making efficient use of energy.

To cool air, we use the Free Cooling method. Sounds refreshing, right? It consumes as little as a hand-held fan, as it uses the outside temperature to keep each of the rooms at the perfect temperature. Since air conditioning represents 40% of a hotel’s electricity consumption, you can imagine how significant that reduction is.

For heating, we use condensing boilers: they produce hot water, which consumes less and therefore pollutes less. This type of boiler is twice as efficient as a conventional boiler.

So, every time you stay in one of our rooms, choose the most comfortable temperature for you. We ensure the minimum energy consumption and the lowest environmental impact.

Every year we support the  #EarthHour. This initiative promoted by the WWF organization (World Wildlife Fund for nature) proposes to turn off the lights of monuments and symbolic monuments to bring attention to the impact of climate change.

NH Hotels plays its part in this initiative, turning off our exterior lights every year from 20:30 to 21:30.  This initiative is considered as the best global campaign to bring awareness to the fight against climate change.

In  NH Hotels we adopt many methods to save natural resources, you can find out about them all by visiting our website.

Do you like ganzing at a starry sky? We do too. That's precisely why the signs and exterior lighting of new NH Hotels  use LED technology. It's the most innovative when it comes to energy efficiency, wich hepls us contribute to the important task of keeping our skies clear.

LED lamps save up to 80% compared to conventional lighting. That's  why since 2011 NH Hoteles have been changing all light bulbs that remain lit longer than 12 hours, wich has resulted in the replacement of more than 60,000 bulbs. Can you imagine how much energy that saves? To give you an idea, with all those bulbs you could light up 1,970 m of San Francisco's Golden Gate Bridge.

This way,  when you look at the sky you can see your favorite constellation in all its glory.

In most of our hotels, the windows are equipped with high protection sunscreens and heat filters, adapted to the area's climate. These provide better insulation and lower environmental impact regarding energy consumption for air conditioning, as sunscreens reduce the cost of air conditioning by 30%.

A major step forward which means you can relax comfortably in your room at NH Hotels, enjoying the perfect temperature wherever you are.

NH Eurobuilding not just an amazing hotel with many amenities and great facilities. It is also the first hotel in Europe to achieve the ISO 50001 certification. This certifies that each and every aspect of its management is designed to reduce energy consumption to reduce the environmental impact.
