First ClimateHotel: tourism gets sustainable

Enertour destination- The Theiner’s garten BIO Vitalhotel was awarded the first certification of ClimateHotel. This new certification system by CasaClima Agency establishes the criteria for sustainability in the construction and management of tourist facilities.

The Theiner family, owner of the hotel, has been active for over 25 years in the farming and trade of organic products. The theme of "organic " is therefore not just a fad, but a philosophy of long life. The ClimateHotel in Gargazzone offers its guests 53 rooms, a wellness area and a gastronomy exclusively using certified organic products. The challenge of the clients, the architect Domink Rierder (Baukraft Architektur) and the construction team was to reconcile modern architecture with the requirements of environmental building. The result is obvious: the ecological footprint of the hotel was reduced -compared to traditional accommodations in the same category- more than 80%.

The floors that house the bedrooms were made ​​of solid wood. The largest trial for the architects was to make the rooms free of allergens and electromagnetic pollution. The problem of sound transmission between rooms was also solved by a particular type of construction of the ceilings and walls. The walls of the rooms, as well as the exterior walls were built using an innovative system called "Soligno”, which provides a built in solid wood elements totally without glue or metal parts. This type of wall, which has an extremely low coefficient of heat transfer, has been used in combination with ecological insulating materials of highest quality.

The hotel’s heat index is about 50 kWh / m²a and has, as calculated by the CasaClima Agency, CO2 emissions of less than 20 kg / m²a. The heating and cooling of the building is controlled entirely through a system through floors and walls. The thermal energy is produced by a solar thermal plant (110 m²) and a natural gas boiler of high efficiency. The hotel also uses the excess heat of the wellness area for energy purposes. A considerable part of the supply of electricity is instead produced thanks to a photovoltaic system (124 kW). Much attention was given to water saving and the use of rainwater.
