We are conscious that a Heritage that is not sustainable will be lost. For this reason, is born Eficiencia y Patrimonio.


 We provide alternatives and solutions that help improve the energy efficiency of historic buildings preserving its character, values and historical integrity.



        We believe that Heritage must be sustainable. We, therefore, propose strategies to achieve:

               - Cost savings. We lowered the monthly expenditure on payment of energy supply.

               - Ecological Benefit: We help to decrease emissions of CO 2 emitted by the building.

               - Energy Efficiency: We reduce demand kWh / year ensuring maximum comfort.

     It is important to promote energy efficiency in the field of architectural heritage. These actions require a thorough and meticulous study that combines research with new measures on energy efficiency and technical knowledge, sensitivity and deep respect for the heritage in order to find the most appropriate solutions without affecting the protected elements.


        We provide a personalized and comprehensive service. We take care of everything.
