Single Family Home Son Vida (Mallorca)

  • Variable water coolant volume system.
  • Production of hot water for heating and sanitary hot water through a geothermal aerothermy system (water up to 65 ° c)
  • Photovoltaic solar training.
  • Mechanical ventilation system with heat recovery.

NZEB Building Mendillorri (Navarra)

One of the most efficient buildings in Spain, with Passivhaus certification *

It has a bioclimatic concept, for its high level of insulation and architectural design where heating and ventilation work through a system of heat recovery with post-heating batteries through an aerotherm and a centralized control of the building with probes of air quality in each room and corrective actions for the optimization of the installation.

* Passivhaus certification, a document that certifies sustainability according to certain requirements such as thermal insulation, air quality or the use of the sun.

House of Culture Blanca d’Anjou (Tarragona)
