On September 19, 2018, the inauguration of the Rural House renovated according to the Enerphit standard in Casalarreina was held.

More than 100 guests attended the inauguration, including the President of the Autonomous Community of La Rioja.

The reference work has entered the FEDER funds through ADRA, as it is a rehabilitation under a standard of almost Zero Energy Consumption and is the first Rural House in La Rioja designed as a Passivhaus.
