International. Nine of each 10 hotels can reduce their energy expenditure by half with several measures. The roofs and terraces with green roof allow the hotel to take shelter from the rain and save up to 10% with the "awning effect".

On the occasion of the hotel rehabilitation day organized by the Evetson Group in Barcelona, ​​Danosa, specialist in integral solutions for sustainable construction, has shown several measures that hotels can attribute to reduce their energy expenditure.

Thermal insulation is the main measure provided by Danosa to reduce the energy expenditure of hotels. With the insulation of the building, the energy cost would be reduced by 50%. To do this, the glazed areas of the façade have to be replaced and the air leaks must be controlled. With a complete thermal rehabilitation, energy savings could reach 90%, according to the German Passvhaus Building Platform.

Thermal insulation not only reduces energy expenditure, but also reduces CO2 emissions from establishments. This measure is essential, but it must be accompanied by other measures such as waterproofing and preserving water tightness in the most sensitive areas, such as roofs, gardens, kitchens, elevator shafts, basements or exposed facades; thus avoiding the cold sensation and the possible negative effects to the structure of the building.

The roofs and terraces with green roof allow the hotel to take shelter from the rain and save up to 10% with the "awning effect". Noise is the great enemy of comfort, which is why many architects and engineers already use solutions such as the box in box system, which uses a floating box inside another structural box to prevent sounds from sneaking between floors and walls.
