Energy efficiency cost of lighting in an average Greek house

green-energyAccording to the Ministry of Development and the Energy and Natural Resources survey was conducted which shows that the energy cost of lighting in average Greek house is around 17% of total energy consumption, about 134 € per year.

  

To better understand the importance of energy costs in lighting is enough to mention that in the life cycle of a dwelling, the replacement cost of the lamps is about 3%, while the cost of electricity is about 86%.


There are many kinds of lamps for various applications, such as halogen lamps, sodium vapor lamps and vapor hydrogen, but the most common in residential applications are the common incandescent lamps, fluorescent lamps, electronic energy-saving bulbs and lamps LED. One of the most important factors in saving energy in lighting installations is choosing the appropriate bulb for any lighting application, as well as accessory devices.


EU Directive 98/11/EG adopted by the Greek legislation in September 1999, provides the legal framework to classify household lamps for household use. According to a standard method, the lamps are classified into different categories of energy consumption, starting with category A for the most economical to Class G for more intensive.


This classification (ABCDEFG) aims to inform the general public, making the / lamp market energy efficiency directly visible to the prospective purchaser.

Incandescent / Eco 30 Halogen


Incandescent lamps / Eco 30 Halogen with low purchase and maintenance costs, the flux is regulated easily, offer excellent color rendering amenable to direct ignition and reignition hot and functioning in any position (horizontal, vertical, diagonal).
Fluorescent


Fluorescent lamps have a higher light output (about three times) than incandescent bulbs, and their lifetime exceeds 6000 hours.


Economy lamps / LED lamps


Modern economic lamps, for the same level of brightness with ordinary incandescent lamps, they have 10 to 30 times longer lifespan (10,000-30,000 hours), and one-fifth of the electricity consumption. The purchase cost is higher but although the overall economic benefit for their use is important as a result of low power consumption and longer life (1 bulbs equivalent to 10 ordinary bulbs).


Some simple measures exoikononisis energy in the operation of lamps, is the following:


Compare the power consumption at the time of buying a bulb from the indication on the label because there are large differences between different types of lamps.

In places where lights work longer (kitchen, living room or outdoor night lighting), energy consumption can be reduced approximately 5-fold if replace ordinary incandescent bulbs. It may cost more, but it is much more economical and have a longer lifespan.

This classification (ABCDEFG) aims to inform the general public, making the / lamp market energy efficiency directly visible to the prospective purchaser.
