The cost of building a luxury Passivhaus villa in Jávea and the Marina Alta typically is increased in a 3% with respect to a traditional construction, depending on the design, finishes, and the topographical complexity of the plot. Although this represents a slightly higher initial investment, the difference pays for itself in the short term thanks to a drastic reduction in energy bills and maximum thermal comfort.
To help you make the best decision, we break down with complete transparency exactly what goes into the budget of an energy-efficient home on the Costa Blanca.
What factors determine your home budget?
To accurately calculate how much a Passivhaus costs in the Marina Alta, we must consider these three key elements:
- The plot and foundation: Building on sloped plots with sea views requires retaining walls and more complex foundations, which increases the overall investment.
- High-efficiency materials and systems: The budget encompasses triple-glazed windows, ultra-thick insulation (such as ETICS - Exterior Thermal Insulation Composite Systems), and advanced aerothermal and mechanical ventilation systems with heat recovery.
- Official certification: Achieving the international seal requires rigorous airtightness testing (such as the Blower Door test) and the use of certified materials that guarantee the home's excellence.

Frequently Asked Questions (FAQ)
1. Is it more expensive to build a Passivhaus than a traditional villa on the Costa Blanca?
Yes, the initial investment is slightly higher (typically a 3% more) due to the superior technology and quality of the materials. However, this difference is amortized in just a few years thanks to minimal energy consumption.
2. What are the real energy savings when living in a Passivhaus?
The savings are drastic. A certified reduces energy demand by up to 90%. If you opt for the Passivhaus Plus standard, the home generates its own energy through solar panels, reducing cooling and heating costs to almost zero.
3. Does the construction quote include the official certification?
Yes. At Bersife, our budget covers all the technical processes, certified materials, and airtightness tests required to obtain the official seal from the Passivhaus Institut.
