Rehau Exposes in Ingurubide solutions to improve the energetic classification of the buildings
24 June 2013
The certificate evaluates the energetic efficiency of the real estate and awards him a classification in a letter that will vary of the To to the G, a similar system to the of the appliances of seven scales. In addition to the information on his energetic characteristics, the certificate will include recommendations for the improvement of the energetic efficiency of the real estate.
The managers of
Daniel Moral stood out that the energetic classification favours the reduction of the energetic consumption, the economic saving, revaloriza the real estate in the market; it improves the conditions of the building, respects the environingingment; and it allows the obtaining of helps and subsidies.
The heating/air conditioning, with near of 76%, is the manager of the greater energetic cost of a building, followed to a lot of distance of the sanitary ware hot water (13%), power (6%), or lighting (2%). The greater part of the heat is used to produce by the windows, with 37%; followed of the external wall, with 35%; the cover with 15%; and the floor with another 13%.
To improve the classification, signalled Igor Gutiérrez, has to act in the reduction of energetic losses (improvement in the windows, enclosures, and isolation of faã§ades); aprovechamiento of the renewable energies (geothermal sensors, biomass, solar, or ecoventilación); and an efficient distribution of the power (systems of heating/refrigeration through radiant surface, system of efficient regulation and pipes preinstaladas of district heating).
Juan Ramón Castro, boss department of windows, detailed the technological evolution of the windows from mediated of the 20th century. Until then, in his greater part were wooden and ironinging, and from 1958 begins to incorporate new technologies like the PVC, the polymer (1968), the central board (1976), the two cameras (1980), the third camera (1994), the new generation of insulating glasses (1998), or the profiling with four and until five cameras (2000). The current systems delete the thermal sensors bridges and achieve energetic savings of until 76%.
The technology Rehau is implanted in numerous edificaciones residential, public or industrial equipments. Between the most recent examples of his possibilities finds the Saint Palace Cristóbal of Zalla, a real estate of the 18th century that has attained the energetic qualification To, the maximum category, by the different systems of saving entered in the real estate.
Between other measures, this house has a thermal sensors isolation reinforced in the envolvente, using external carpentries of high quality, inner thermal sensors mass and ventilation crossed. Also it has realised a ‘free heating' taking advantage of in the cold months the power produced by the warming of the solar manifolds and that serves to heat the radiant floors. This energetic rehabilitation has made possible to win the third prize of the I Edition of the International Contest Sustainable Urban Buildings 2013, organised by Construction21 and Metropolitan Solutions.
