Rehabilitación energética

Europe has recognized the necessity of adaptation to a world with a growing resources scarcity; therefore the efficiency is the angular corner of the Europe 2020 strategy, which states to reach a 20% reduction for the primary energy consumption. Considering that the buildings consume about a 40% of the final energy in the European Union, reducing their energy consumption is a key factor to get the 2020 European objectives.

The energy refurbishment aims at reducing the building’s energy demand, decreasing the energy consumption, by means of optimizing the building envelope and improving the efficiency of the heating and hot water system. Hence it is possible:

  • Improve the dwelling habitability conditions.
  • Improve the thermal comfort and acoustic isolation.
  • Diminish the user’s electricity bill.
  • Increase the dwelling value

The energy performance of a building is optimized when the design takes into account the weather conditions and also is equipped with efficient energy systems. The following combination of both active and passive factors is necessary to reach the energy efficiency:

  • Improve the thermal insulation of the building envelope.
  • Reduction or elimination of thermal bridges.
  • Improve of the building fenestration, glass and air tightness.
  • Control of the renovation and quality of the indoor air.
  • Install efficient heating and hot water systems.
  • Incorporate elements for passive control.
