Because this project shows that decarbonising a building does not have to mean choosing between heritage, comfort and efficiency. A 19th-century farmhouse has been transformed into a five-star boutique hotel where several thermal technologies work together as one intelligent system. Heat pumps provide heating and cooling, underfloor heating delivers silent radiant comfort, and surplus heat that would otherwise be wasted is recovered for domestic hot water. Airzone coordinates these systems from a single control environment, down to individual guest-room level. What makes the project particularly compelling is that the technology is almost invisible. Guests experience a historic countryside hotel rather than a technical installation, while behind the scenes the building continuously coordinates different HVAC systems to use energy more intelligently. La Dehesa de Don Pedro demonstrates a highly replicable principle for Europe’s renovation challenge: historic and character buildings can retain their identity while adopting smart, efficient heat pump solutions capable of meeting modern expectations for comfort and sustainability.
