5 keys to energy rehabilitation

Theenergy rehabilitationIts objective is to reduce the energy demand of homes. Hethermal insulationIt is one of the most important and immediate solutions: the better insulated our home is, the less energy it will consume.

1. What does an energy rehabilitation contribute to the home?

An energy rehabilitation throughthermal insulationcontributes to creating healthy and comfortable environments. In addition to saving energy, the noise level inside the home is reduced. Acoustic comfort is relevant since excessive noise can cause discomfort and even health problems. In addition, it prevents condensation andappearance of humiditywhich can damage the home and encourage the appearance of mold.

2. Why is it so important to eliminate thermal bridges?

When we insulate roofs and walls we prevent them from appearing “thermal bridges”, areas through which heat filters more easily than the rest. In addition to causing a very significant loss of energy – between 20% and 40% of the total heat loss of the building envelope -, “thermal bridges” cause the appearance of “cold spots” on the interior walls, which lead to the formation of humidity, condensation and make the rooms less comfortable.

3. What regulations must we comply with in energy rehabilitation works?

If we carry out a rehabilitation work that affects an area greater than 1,000 square metres with a renewal of 25% of the enclosures (roofs, walls and floors), compliance with DB HE1 of the Technical Building Code on energy saving is required. A requirement that establishes that buildings will have an envelope that limits the energy demand necessary to achieve thermal well-being.

4. How much energy can we save with energy rehabilitation?

Heenergy savingIt will depend on the type of home we have. In general, for an energy rehabilitation project, savings in energy consumption can range from 5% to 20%, as well as annual savings on the energy bill between €500 and €2,000 per building.

5. How long does an energy rehabilitation take to pay for itself?

Thermal insulation requires an investment that can be easily amortized thanks to the reduction in heating and air conditioning costs. Thermal insulation such asTHERMOCHIP® sandwich panelsIt guarantees a long useful life, so that a thermal rehabilitation can pay for itself perfectly in less than 10 years.
