With the arrival of summer, the increased use of air conditioning devices to grow 45% in energy consumption resulting in a significant increase in electric bills. Now more than ever, to the current economic situation of Spanish families is necessary to adopt all measures that contribute to savings accounts.

“The effects on the economy caused by rising domestic consumption of electricity during the summer months can be minimized to 30% if you adjust the insulation of homes, promoting energy savings”, says Jordi Bolea, head of the department of technical and Regulatory Certification Rockwool products.

Thermal insulation is the key to saving energy at home.

Isolation is one of the most cost-effective measures to reduce demand for energy because it avoids energy losses through the deck and walls.

According to data from the IDEA (Institute for the Diversification and Saving of Energy), in Spain more than half of the buildings are built without adequate thermal protection. One of the key solutions for reducing energy consumption is the implementation of passive energy rehabilitation measures, based on increased levels of insulation in buildings.

According to Jordi Bolea, "Energy efficiency resultant of better insulation of houses is the main source of savings. An environmental, thermal insulation is a significant savings in energy consumption and is reflected in an estimated decrease of 30% in the electricity bills. All this without losing quality or thermal comfort and made a consequent reduction in emissions of CO2."

Why save energy?
The potential of energy savings through the buildings not only translates into a saving on the bills but also helps reduce CO2 emissions to the atmosphere.
"Being responsible in the use of air conditioning helps to improve the environment, reducing the emission of polluting gases. Energy efficiency has become the largest source of energy," says Jordi Bolea.
This is one of the main objectives of the Fifteenth United Nations Summit on Climate Change to be held next December in Copenhagen, to negotiate the document on energy efficiency to replace the current Kyoto Protocol (which expires in 2012).
Energy certification for buildings
It is required to make available to purchasers or users of the new buildings Energy performance certificate describing their energy characteristics since last November 1st.
With this legislation, all newly built homes or buildings where there are alterations or rehabilitation to renew more than 25% of all building fences are required to have an informative label Class Energy Efficiency, which will vary from Class A, for more energy efficient, to class G, for the less efficient. According to Jordi Bolea, "It is important that users will recognize this certificate as a guarantee for energy savings."
