🌱 Cuatro Caminos II: a Passivhaus building

Spain’s first timber-structured Passivhaus coliving!

You’re living in a Passivhaus building!
Designed for maximum comfort, clean air, and ultra-low energy use.

What is Passivhaus standard?

The Passivhaus standard is a benchmark for the design, calculation, and construction of highly energy-efficient buildings — both new builds and renovations — in any climate and for all building types. It aims to provide maximum comfort, excellent indoor air quality, and near-zero energy consumption.

Developed in 1990 by the Passivhaus Institut in Darmstadt, Germany, this standard is the result of a rigorous design process and strict on-site quality control. A Passivhaus building offers significant energy savings compared to a conventional building.

What makes your home special?

  • 🧊 Thermal insulation: stable indoor temperature all year round
  • 🪟 Triple-glazed windows: airtight and super efficient
  • 💨 Continuous ventilation: fresh air 24/7 — no need to open windows
  • ❄️ Efficient climate control: quiet heat pump system
  • ☀️ Solar + renewable energy: save money and reduce your impact

Tips to make the most of your Passivhaus home


To get the best experience from this Passivhaus concept, we need an active community — we need you! 🤝
  • 🪟 Windows
    You don’t need to open them to ventilate — the system handles it for you.
    In summer/winter, keep them closed to stay comfortable.
  • 🚿 Hot water
    Hot water is produced centrally with solar energy ☀️
    Use it efficiently (e.g., short showers).
  • 🌡️ Climate control
    Ideal temperatures: 20°C in winter, 25°C in summer.
    Use responsibly.
    If you open windows, turn off the A/C.
  • 🌞 Solar shading
    In summer, lower the blinds to block heat.
    In winter, raise them to let in natural warmth.
  • 👩‍🍳 Cooking
    Always use the extractor hood (with carbon filter).
    Strong cooking? Turn up the ventilation or crack open a window.
  • 💡 Electricity use
    The building is equipped with LED lighting and energy-efficient appliances.
    Use responsibly.
    If possible, run the washing machine/dishwasher during the day (☀️ = free energy!).
