We are at a very interesting moment when considering a reform in our house. On one side are appearing regulations urban character posed new initiatives when save energy in cities, and other, to a smaller scale, changes have been made in the basic documents of the technical code to promote reducing consumption and energy demand in residential buildings.
There are some points that can be very important when facing a efficient housing refurbishment, some already commented on this blog
Must take into account that between 15 and 20% only energy consumption in Spain occurs in homes. For this reason it establish basic criteria that can help make decisions when reforming our homes.
The elements that consume inside housing are, far, appliances, hot water, and heating, while lighting and air conditioning remains at around consumption 15% Total between.
The windows is where greater thermal bridges occur in homes, It is for this reason that good materials, as can be PVC, followed by a proper installation helps greatly that the temperature is maintained and no points appear significant loss of temperature. The most important difference between a material such as PVC and aluminum carpentry classic, is that the former is an insulating material, while the latter is not. In like manner, placing a low emissivity glass can be reduced by 20% energy loss over a conventional glass.
Installing leds, or bulbs low consumption You can get to consume 70% less energy in the field of lighting.
Another very important area for reform is the installation of thermal insulation both facades horizontal elements and (floors and ceilings). Placing sheets from rockwool 2 and 4 cm or polyurethane foam injection solutions are very efficient when replacing these items. In soil, the most efficient element is extruded polystyrene.
Last, choosing to install heating, condensing boilers can expect to save hast one 25% Power. In like manner, the choice of appliances with energy label AA helps reduce energy consumption in the reform of our house.
