How to improve energy efficiency in a flat
A 88m2 flat in San Sebastian (1975) with an F energy rating can be significantly improved by insulating the façade.
This can save up to €222/year and can help your home achieve a D energy rating.

From normal home to optimised home

In addition to achieving significant savings, these improvements optimise sustainability. They do so by significantly reducing the pollutant emissions of the home compared to its initial energy consumption:

Thermal insulation is one of the most efficient and cheapest technologies for improving thermal comfort. This solution avoids 30%-35% of the heat loss or cold coming in and is installed in a single day.
 

Tangible results, great benefits

Having a D rating on the energy performance certificate is a sign of sustainability and commitment to the planet.

Short-term benefits
  • Energy efficiency in summer and winter.

  • Thermal comfort.

  • Sustainability. Reduction of polluting gases by using less energy.

  • Revaluation of the home.

Notable reductions
  • Energy consumption. Lower costs for boiler and air-conditioning (A/C) consumption.

  • C02 emissions. Reduction of greenhouse gases.

  • Electricity bills. Savings on electricity bills.

Sustainable and economic benefits
The changes will optimise the energy efficiency of the home, which will be upgraded from an F to a D energy rating. This will reduce CO₂ emissions and energy consumption.

Façade insulation will prevent energy losses and contribute to savings in the home.
