Sustainable beach homes: how to find energy-efficient properties and save on your second residence

Buying a beach house is a dream for many, but if you want to truly enjoy it and save money in the long term, choosing a sustainable and energy-efficient property is more important than ever. At Munfort, we explain how to identify efficient properties, what advantages they offer, and where to find the best options to combine quality of life with savings.

What is a sustainable beach house?

A sustainable home not only reduces environmental impact but also allows owners to significantly save on electricity, water, and cooling costs—crucial in coastal areas with hot summers.

Key features of an energy-efficient beach house:

• High energy rating (A or B) indicating low consumption.
• Double or triple-glazed windows with thermal break.
• Insulated walls and roofs to reduce air conditioning needs.
• High-efficiency climate systems (aerothermal, underfloor cooling, etc.).
• Renewable energy: photovoltaic panels for electricity or solar thermal for hot water.
• Low-consumption appliances (A+++).

How much can you save with an efficient property?

According to Spain’s Institute for Energy Diversification and Saving (IDAE), average annual energy costs in a Spanish home are around €1,200–€1,500.
In a home rated A, savings can exceed 60% compared to a property with an E rating or lower.

Real example:
Traditional home: €120/month for heating/cooling → €1,440/year.
Efficient home: €50/month → €600/year.
Estimated annual savings: €840, which is over €8,000 in 10 years.

Why is it important in a second beach residence?

Many vacation homes remain empty for weeks or months: an efficient property can stay in good condition with minimal energy use for ventilation, dehumidifiers, or climate control.
With electricity prices in Spain up 80% since 2020 (Eurostat), savings are even more crucial for non-resident owners.
Efficient properties are increasingly demanded in the vacation rental market and can rent for 10–20% more than older homes (Idealista, 2024).
