In general, the predominant feeling that when you get home there must be conditions pleasant comfort. At the same time, however, these conditions involve achieving economic cost. Building homes with tight budgets, controlling the speed to quality, has caused many homes to become energy inefficient. Materials of low quality, poor insulation or walls, unfavorable orientations are some cases that can be observed. In this situation, targetti sankey the Government of Catalonia prepared Decree 21/2006 with the aim of incorporating environmental parameters and eco-efficiency in buildings, but even a step ahead of the rest of the state. In the decree, four parameters are defined eco-efficiency: energy, water, materials and construction systems and ultimately waste. In today's targetti sankey article, we will focus on one of these parameters with: energy, specifically the energy devoted to lighting and spaces. For centuries, the sun has become the key to human activity (among other areas) targetti sankey acting as a temporary marker and influencing mood (both psychological and physiological). Given this source of energy must take it and take it to the inside of the buildings because these properties are developed. But what about the places where natural sunlight is not present normally? Or in buildings that have few openings to the outside? Affect the proper development of the activity inside? Some studies in workplaces, for example, prove it. This may suggest how important the lighting and a space, however, and should brighten correctly and according to the type of activity targetti sankey being performed. When choosing what type of lamp Place cabbage in a public space or workplace, must take into account several parameters: targetti sankey what is the luminous flux of the lamp, the luminous efficiency, luminaire or polar diagram which has lamp (among other parameters). Until recently, the most commonly used lamp was not halogen bulb. With a high color rendering index and low cost, however, has a very low light performance (part of the electrical energy it consumes into heat energy being lost only 5% of energy is transformed into light) . Currently, this lamp is in most homes but has a termination date since according to European directive (as trasposada Spanish Royal Decree 187/2011 through) will prohibit the manufacture of energy-related that are not governed by criteria of ecological design. Thus, the manufacturers of this type of lamps will sell them until the completion of stocks. The alternatives are from incandescent halogen through the compact fluorescent (known as energy saving lamps) without leaving the familiar LED (lighthing emitting diode) with a much higher service life, impact resistant and small. Some of the disadvantages of the LED is that they have high levels of glare (UGR), the high cost and the color reproduction is not as high as in the incandescent. Here you can see then, that according to the characteristics of each lamp, these are better suited to the space and brighten . For example, in areas that require long periods Lighting Fixtures LED's are a good choice. However, businesses aimed, for example, the sale of food, the interests and Lighting is one that emphasizes the colors targetti sankey and make the product more attractive by the customer. Aiming targetti sankey to set criteria to follow in the spaces to be lit and arose Directive 2002/91 / EC also did respecting targetti sankey energy efficiency criteria. In Spain, this directive is trasposada with UNE on and 12464.1 Lighting of indoor workplaces posing as three key criteria parameters, and maintained luminance (amount of luminous targetti sankey flux reaching a surface) limits UGR ( glare) and color rendering index. In this document, you can see a detailed listing of buildings and spaces depending on the type of activity that takes place, the minimum requirements Lighting fixtures vary. As an example targetti sankey of the variability of spaces that can be can be seen in Table 1 have the respect these limits targetti sankey will study what kind of cabbage Place lamps at the same time, we also need to pay attention in the light, ie, the support containing the lamp. It is a party in itself does not require power, but can become key in the correct use and addressing the luminous flux where you want (photo 1).
Finally, there is the Spanish Technical Building Code becomes of
