Given these worrying figures, the European Union has already published a series of recommendations to reduce pollution and energy consumption, among which is the rehabilitation of homes.
Rehabilitation of homes to reduce energy consumption
Regrettably, in Spain the rehabilitation of buildings prior to 1980 only represents 0.62% of the total. According to the latest study published by the Institute of Construction Technology (ITeC) if in the last five years’ rehabilitation façade works had been carried out with energy efficiency criteria, it would have increased energy improvement by 6.7 times.
In this sense, the countries that have achieved greater energy efficiency are Germany, Italy and Japan.
Certificate of efficiency
"In Europe, the per capita expenditure on housing rehabilitation is €789, in Spain it is €303".
Obtaining the energy efficiency label is mandatory since 2013. Homeowners must request it for a certifying technician to inspect the home and determine the level of energy efficiency.
Among the key aspects to achieve a better qualification are the rehabilitation of houses, good insulation of facades, roofs and windows or air conditioning systems, such as boilers and pipes.
