LABEL EFFICIENT WINDOWSENERGY EFFICIENT WINDOWS
The publication in the Official Gazette (No. 53, March 3, 2011) of Royal Decree LABEL EFFICIENT WINDOWS of February 18 on the establishment of eco-design requirements applicable to energy-related products is part of measures taken in Spain to accommodate the European Directive, Directive LABEL EFFICIENT WINDOWS LABEL EFFICIENT WINDOWS EC of October 21, 2009, on ecological design criteria, whose aim is to establish eco-design requirements applicable to energy-related products that will increase energy efficiency and security of energy supply, reduce emissions of greenhouse gases and contribute to sustainable development and environmental protection. It applies to energy-related on that are applicable implementing measures in order to be placed on the market or put into service, including the windows products.
Replace energy-inefficient windows other better performance is one of the measures either individually can be implemented to improve the energy efficiency of housing. To assist users in choosing energy efficient windows the Spanish Association of Manufacturers of light facades and Windows (ASEFAVE) has developed a system of energy efficiency labeling for windows that will differentiate ventanasde quality and efficient that they are not , by measuring four basic parameters: thermal transmittance, glass thickness, sound attenuation and air permeability. This label energy efficiency of windows is currently voluntary and is already being used by some manufacturers of windows, although in the future it is anticipated that mandatory.
For those users who are thinking of changing your windows more energy-efficient and, considering that the energy efficiency label windows has peculiar characteristics we want to explain here the contents of this tag. The first thing we find in them is the data of the window manufacturer, model and registration code
The following is a classification system for energy efficiency of windows distinguishes between two climatological variables: summer and winter. In the part of the left LABEL EFFICIENT WINDOWS it is for the energy performance of the window in winter, composed de7 levels LABEL EFFICIENT WINDOWS A (most efficient) to G (least efficient). In the part of the right is LABEL EFFICIENT WINDOWS energy efficiency of the window in summer with 3 levels of efficiency three stars for the most efficient and effective for less.
Finally at the bottom of the technical data of the window are collected: Thermal transmittance of the frame, glazing and window, ie, the flow of energy through the window and each of its elements from the hot side LABEL EFFICIENT WINDOWS Air permeability of the window or what is the same property to prevent air leaks between separate LABEL EFFICIENT WINDOWS Solar factor of the glazing of which depends on the degree of transmission of solar radiation into the housing.
Each manufacturer is responsible for labeling windows and the veracity of the information contained on labels for energy efficiency of windows and in no case can be used to calculate the actual energy savings because it will depend on factors as the placement of it, the location of the property or the existence of mechanisms such as the use of shading blinds or awnings.
