Buildings consume more energy than the transport sector (33%) or the industrial sector (26%), according to data from the Institute for Energy Diversification and Saving (IDEA). And it is that homes in Spain are a great drain on energy, Due to the age of the Spanish real estate stock, built mostly before 1990, being very deficient constructions from the energy point of view. If we add to this, that in June there was a change in the electricity tariff, which directly affects consumption in certain time slots; and the heat, typical of the summer season in which we find ourselves, we can affirm that we are facing a great problem for many Spanish pockets.
For this reason, and coinciding with the expiration of the first month of operation of the new electricity bill, the home improvement platform, habitissimo has recalled some reforms that you can do to avoid power leak points and to be able to reduce energy consumption.
The first and most important is to have a good insulation of the roof and facade of the building, “This will allow us to stabilize the interior temperature in such a way that, if there is good ventilation, the houses will not need air conditioning, except on hot summer days,” they say from this company. For individual interventions, the insulators can be placed from inside the house, inside the wall or attached to it.
It must be borne in mind that if these improvements are made within the framework of a comprehensive reform, the cost will not be so high. For a work of 30,000 and 40,000 euros, the budget would be more expensive between 10% and 20%, but in the long run it would allow a minimum saving of 40% in air conditioning expenses. «If the home is older than the eighties, the reform can provide energy savings of between 30% and 80%, if it is later, it reduces the cost between 30% and 60% “, they add from habitissimo. These reforms can be deducted up to 60% in personal income tax, through the Government’s ‘Recovery, Transformation and Resilience Plan’.
The Windows are the most important elements when it comes to ensuring proper insulation of the house, and do not let the heat pass through. To increase the insulation one of the best options are those that have a thermal bridge breaking system that integrate an insulating element that prevents heat from entering. In addition, we must not forget that an optimal glass is as important as a good window, since up to 25% of the energy in homes is exchanged by the windows. The price will depend on the size, between € 200 for a window and € 900 for the sliding windows of the balcony. This must be complemented with the installation of motorized blinds, since by the hands together with the drums, they are vanishing points, therefore it is advisable to isolate them.
Another small reform that can help reduce energy consumption is the installation of controlled mechanical ventilation systems, capable of expelling stale air and introducing new from outside. «Currently, there are heat recovery units capable of extracting stale air at 24 degrees and recover it without particles and at a minimum of 22 degrees “, they indicate from the habitissimo platform.
Lower the air conditioning bill
Undoubtedly, with the arrival of summer, one of the biggest concerns for Spaniards is how much the price of the new electricity bill and air conditioning in the house will increase, a resource that in some houses and regions, seems essential. In order not to increase consumption excessively, experts recommend getting an air conditioner that meets some requirements that guarantee the highest efficiency. Thus, they underline the importance of look at the power of the appliance, its energy classification and sound pressure. “Depending on the size of the room that we want to condition, we will need one power or another, being, for example, around 2.7 kW sufficient for an area that does not exceed 30m²”, they indicate from habitissimo.
In addition, it is important to look at the energy classification of the appliance, which will indicate the relationship between the frigories produced by the appliance and the electricity consumption. Thus, appliances with the A +++ label will be the best when it comes to saving at the end of the month on the electricity bill. “Although the initial outlay on household appliances with the best energy classification may be higher, in the medium term it can lead to savings of up to 50% on the bill,” they indicate from habitissimo.
Another tip is to bet on those solutions with Inverter technology, which detect changes in temperature and are capable of supplying the necessary power at all times. “This type of device can help us reduce the bill by up to 25%, since in addition, many of them have presence control, which allows the device to work automatically depending on whether it detects movement in the room”, they point out.
In this sense, they also recall the usefulness of the “Eco” modes, which many of the new devices already have and which allow rreduce consumption and night function by up to 30%, which allows the functions to be programmed so that they are suspended at night and does not affect consumption. In addition, installing a good thermostat will contribute to saving up to 15% on the bill.
Finally, from habitissimo they remember that other solutions, such as installation of awnings and windows with good insulation, will contribute to improving the air conditioning of the home, reducing consumption in air conditioning systems and therefore, save on the electricity bill at the end of the month. “This type of improvement can reduce the interior temperature by up to 10 degrees, avoiding the ‘magnifying glass effect’ and improving the air conditioning inside the house”, they conclude from habitissimo.
