How to make a house produces a minimum environmental impact on the environment through energy favorable.

The information system electrical energy behavior established by the European Directive 92/75/EEC (22/09/1992) has been deprecated in the next few years will grow to incorporate new classes A +, A + +, A + + + and eliminate those less efficient (E, F, G).

Efficient appliances, that are energy labels

Appliance manufacturers in European Union countries are required to label an informational tool to indicate the amount of energy in products such as dishwashers, dryers, washer-dryers, refrigerators, freezers, household light sources, electric furnace and air conditioning. These labels are regulated by European Directives through royal decrees and are classified into seven classes of different labels depending on the power consumption to perform each. They are distinguished by color and covering letters of the alphabet from A (most efficient) in dark green to G (least efficient) to dark red. They all refer to the energy efficiency class, name and brand of device. In this way users do valuations of the goods of the same type or range of appliances but in different makes and models. These labels are mandatory for all manufacturers including store sales on-line as Redcoon or pixmania . Thus the consumer contributes to energy saving, environmental protection and responsible consumption.

Objectives of the IDEA and the “Practical Guide to Energy”

The public corporation IDEA (Institute for Diversification and Saving of Energy) was created by the General Secretariat of Energy attached to the Ministry of Industry, Tourism and Trade to promote diversification of renewable energy. To do this in 1996 published a reference book at information for the public called “Practical Guide to Energy” in which information is organized into seven chapters and identifies the different energy consumption that occur in everyday life and how to improve through practices first edition is published in 2004 as in 2007 the second run successfully distributed in major national newspapers with more than seven million copies in print.

Its last edition in July 2011 with a total circulation of 50,000 copies redesigned and became the third with more fresh news from the date of which was his second edition in 2010. Similarly IDEA seeks to serve the consumer a database with all the appliances with energy labeling of existing Class A or higher in the Spanish market. This data is updated regularly with other manufacturers like ANFEL (National Association of Manufacturers and Importers of white goods) or ANGED (National Association of Large Distribution Companies) that have been voluntarily added to this database.

New to the third edition of “Practical Guide to Energy”

The energy label on appliances is reviewed every four years which promotes technological development. The latest revision was approved in 2010 by the European Commission and take effect in December 2011. Their classification will from A to G but adds three additional energy classes:

Class A +: for units with a consumption of less than 42% of average consumption for a product equivalent to the same range. In washing is the most efficient class and is identified in dark green being the letter F the lowest of them all.
Class A + +: on appliances that consume less than 30% as the refrigerator.
Class A + + +: is the most efficient energy class and assigned to products that use less than 24% as air conditioning and refrigerators being the letter D the lowest class.

All of them will be reflected in a single label for the 27 member countries of the European Union.

Other innovations for energy labeling on appliances

Other developments in the energy label for appliances includes changes ranging from easy viewing by replacing the text to the noise level at different descriptive pictograms summarizes the characteristics of the device. Some of them are:

Annual energy consumption: based on amount of energy normalizations by a test trial in hours (refrigerated) or wash cycles (washing machines). He is identified by an estimated consumption of energy by a number expressed in kilowatt-hours ( kWh ).
Storage volume: in refrigerators and freezers this pictogram in liters ( l ) controls the storage volume available for non star rated compartments (symbol of a refrigerator) and frozen (symbol of a star).
Capacity of product: washing is expressed with a number of kilograms ( kg ) using a t-shirt symbol and identifies the ability to take the clothes inside and another expressed pictogram associated with a letter that the efficiency of spin (T-shirt drop of water).
Intensity noise: it is expressed in decibels ( dB ) associated with product performance on stage wash and spin washing machine (symbol sound level).

Some appliances efficient provision of energy rating A, A +, A + + and A + + + are the least spending, consuming up to 2/3 parts less power than Class C and providing an energy saving important consumers and the environment.
