Housing rehabilitation to reduce energy consumption and pollution

Rehabilitación de viviendas Sistema Masa

The high-energy consumption of homes causes worrying levels of pollution. The residential housing is responsible of the 18% of total energy consumption and 8% of pollutant emissions, according to the latest data from the Ministry of Agriculture, Food and Environment of Spain.

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

The first step to becoming aware of the problem and taking action is to think that housing rehabilitation is not an expense, it’s an investment. As we have already mentioned on other occasions, the rehabilitation of houses improves the aesthetic appearance of our house, reduces noise and reduces the use of harmful components, among other advantages. All this means an increase of up to 40% in the electricity bill.

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

According to experts, starting with the F letter we can save up to 75% of energy by simply carrying out a housing rehabilitation that consists of improving the isolation. In fact, another of the data that highlight the ITeC study is:

"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.

Almost Nil Energy Buildings by 2021

Pollution and the lack of energy efficiency of housing are of concern to the European Union. To improve emission levels and to raise awareness of society, the EU recently published a document with recommendations on Near-Nil Energy Consumption Buildings (DEEE). The EU calls on member states to take action and require public buildings to be DEEE before 31 December 2020.
