In the construction of new buildings and the renovation of existing structures, designers
are required to design facilities with low energy demand and to include solar energy and other renewable energies, such as CHP, in order to reduce conventional energy consumption. The building in this case is a hotel in which solar energy has been replaced by a Dachs micro-CHP system. The hotel is located in the heart of Astorga, a city of great heritage in the province of León. The building was originally an Art Nouveau gallery, prior to being renovated and converted into a spa hotel.
The provisions of the Spanish Technical Building Code (CTE) stipulate that when thermal energy generation facilities are modified, the contribution of the new facility must be equivalent to that of a solar energy system.
Because it was considered that the solar installation might devalue the heritage value of this historic building and because the CTE allows for the reduction or substitution of such a system by systems such as CHP, a proposal was made to replace it.
